INTRODUCTION The Federal Energy Regulatory Commission (FERC) license granted to the Alaska Power Authority (now Alaska Energy Authority) for the Bradley Lake Hydroelectric Project (Project No. 8221) stipulated that a plan be developed and implemented to monitor the abundance of salmon in the Bradley River. Studies per the approved monitoring plan (Alaska Power Authority 1986a) were conducted from 1986 through 1995 with the intent of providing a yearly index of salmon abundance during both the pre-operational and post- operational periods to allow an appraisal of project impacts to salmon resources of the Bradley River. Additionally, a study of salmon attraction to the powerhouse discharge (tailrace) was initiated in 1992 and completed in 1993. The results of these studies are reported in annual reports for the above years. A summary of the study results from 1986-1995 is included in the 1995 Final Report (Alaska Energy Authority 1995). Submittal of the 1995 Final Report constituted completion of the required fisheries monitoring per the FERC license. However, the Alaska Energy Authority elected to continue the salmon escapement monitoring program for an additional three years to provide a longer period of record and better establish salmon population trends in the Bradley River during the operational regime. This report presents the results of the first year of investigation under the extended study program. Operation of the Bradley Lake Hydroelectric Project began in the fall of 1991, consequently 1992 was the first full year of project operation. However, operational flows were in effect during the summer of 1991 while the reservoir was filling. Therefore, 1996 was the sixth year of the study to examine the salmon resources under the operational flow regime. The salmon resources of the Bradley River have been documented in considerable detail through a series of studies beginning with early permit-related investigations (USFWS 1982; Woodward-Clyde Consultants 1983, 1984; Northern Technical Services 1985) and continuing with the 1986-1995 FERC mandated monitoring program. The Bradley River is a turbid stream of glacial origin, consequently fish cannot normally be visually detected. Various active and passive sampling techniques have been utilized to gain insight into fish populations. The results of these studies have indicated that pink salmon (Oncorhynchus gorbuscha) is the principal salmon species using the river for spawning, although smaller numbers of chum (0. keta), coho (0. kisutch), sockeye (OQ. Nerka) and chinook (0. tshawytscha) also utilize the river. Potential spawning habitat is limited to a short segment of the river due to high gradient and coarse substrate at the upstream end and silty tideflats at the lower end. Pink salmon were identified early in the permit process as the key evaluation species, consequently all study efforts have emphasized this species. OBJECTIVES The primary objectives of the 1996 field effort were to: - Continue monitoring the escapement of salmon to the Bradley River to extend the period of record and provide a better indication of trends in salmon reproduction under the regulated flow regime. - Continue the general assessment of the habitat value of the river under the operational flow regime as compared to the pre-operational flow regime - Gain additional insight into the effects on fish populations as flows are fine-tuned closer to allowable minimums 2 - Maximize the amount of biological information obtained from the study by thoroughly analyzing the data. METHODS Study methodology was essentially identical to that used in the FERC monitoring program from 1986-1995 so that catch and population data would be comparable. The study period was shortened from 9 weeks to 8 weeks to reduce costs while still encompassing the full pink salmon spawning period. Study Area The primary study area consisted of an approximately 2,300-m (7,500-ft) stream segment extending from the downstream end of Riffle Reach to waterfalls above the upstream end of Bear Island Slough (Figure 1). The study area encompasses almost all of the known spawning habitat in the Bradley River systen. One study site was located outside of the primary study area. Fox Farm Creek, a small clear-water tributary to the Bradley River at RM 2.5 was monitored for salmon escapement (Figure 1). Study Duration The study was conducted over an 8 week period from July 23 through September 12. The general timing of the study was originally selected to coincide with the duration and timing of the pink salmon run, based on the results of the earlier studies and confirmed in recent years. Under the normal schedule of sampling, the field crew traveled to the site on Monday evening of each calendar week and intensive sampling took place on Tuesday, Wednesday and Thursday. Trap Net Sampling Trap nets were again used as a primary sampling technique as in the 1986-1995 efforts. The standard project trap nets as redesigned in 1990 (see Alaska Energy Authority 1990) were designed to fish in water as shallow as 0.5 m and proved to work well at selected deeper sites in the river. The redesigned nets are illustrated in Figure 2. These nets were made from 6.35 cm (2.5 inch) stretch mesh nylon. Net wings were attached to the main frame of the net in various configurations depending on the location of the net in the river. The 6 trap net sites established in 1991 for the operational flow regime were utilized again in 1996 (Figure 3). There was no indication that significant stream channel changes had occurred since the 1991 season, consequently the conditions at each net location effectively duplicated the conditions present during the 1991 through 1995 studies. Some of the nets were accessible by boat and some were only accessible by foot. During each typical weekly sampling period, the trap nets in the primary study area were set Tuesday morning and fished until Thursday morning for a total of approximately 48 hours, after which they were removed from the water until the following week. During normal operations, each net was checked every 4 hours during the daytime and then allowed to fish overnight. Some variation in the typical sampling regime occurred because of the difficulty accessing nets during extreme high tides. Sampling times were delayed by 1-2 hours during those days when unusually high tides coincided with scheduled sampling times. The fish were removed from the nets at each check, identified to species, measured, and salmon species were tagged using sequentially numbered Floy spaghetti tags. Larger Dolly Varden were marked by punching a hole in the upper lobe of the caudal fin. Sex and spawning condition were recorded for all salmon. Spawning a condition codes were as follows: Code Condition 1 Fresh, non-spawning coloration, silvery 2 Spawning coloration, not ripe 3 Ripe, eggs or milt readily stripped 4 Spawned out 5 Visible deterioration 6 Dead Beach Seine Sampling As a supplemental sampling method, beach seining was conducted during Weeks 1 through 8. Seine sites are indicated on Figure 3. Sites S1 and S3 were seined consistently each week and site S7 was seined during Week 5. In most cases two hauls were made at each site. The seine utilized was 100 ft. long by 6 ft. deep, constructed of 2.5 in. stretch mesh netting. Captured fish were processed in a manner similar to that described for the trap net sampling. Carcass Counts All salmon carcasses observed within the study area were counted and tags were noted. Fox Farm Creek Surveys Visual surveys of fish present in Fox Farm Creek, a clear tributary to the Bradley River (Figure 1), were conducted once during each sample week. Observers walked the entire habitable length of the creek at lower tide levels and recorded the numbers of fish present for each species of salmon and the numbers of fish showing visible project tags. Minnow Trap Sampling A brief survey of juvenile salmon within the main study area was conducted on September 10 and 11 using 1/4 inch wire mesh minnow traps set at 10 locations representing various habitat types between Riffle Reach and upper Bear Island. Most of the trap locations corresponded to locations used in a similar survey conducted in the summer of 1994. The traps were baited with preserved salmon eggs within perforated containers and were allowed to fish overnight for a total of about 20 hours. Biological Data Management Data from field data books were entered into a computer spreadsheet (Quattro Pro) using an IBM compatible microcomputer. Printouts from the spreadsheets were checked by field personnel against the field notebooks. The spreadsheets were edited, correcting any observed errors. Graphs were prepared using the Quattro Pro program. Population and Escapement Estimation The principal methods used for estimating populations were the same as those used in past years to assure comparability of data. Population estimates based on trap net catches were calculated for the primary species of salmon present during each sample week using the Peterson model, as modified by Chapman (Ricker 1975). The following assumptions were used in constructing the model: 1. Salmon numbers remained constant during the 3-day sample period. 2. All fish marked during the previous 2 sample weeks were still present in the study area. 3. Fish marked 3 or more weeks prior to the sample week were no longer present in the study area. 4. Marked and unmarked fish were equally susceptible to 6 capture. In addition, population estimates were calculated based on selected seine catches. Physical Data Collection Air temperature, water temperature, turbidity, and stream stage were recorded daily at the field camp (Figure 1) on those days that the study crew was in the field. Turbidity was measured in the field using an HF Instruments Model DRT15 nephelometric turbidity meter. Stream stage was measured using a staff gage. The gage measurements were strictly relative and were not tied to any datum. Miscellaneous Observations Wildlife presence and other events of ecological interest were noted as they occurred. RESULTS Overall Catch Overall catch for all methods combined (not including minnow traps) is summarized by week in Table 1. Complete catch records for all measured fish are presented in Appendix A. As in past years, all five species of Pacific salmon indigenous to Alaska were captured in the Bradley River. Pink salmon again were the most abundant species with a total catch of 636 fish. Substantial numbers of chum (154 fish), coho (204 fish), sockeye (309 fish), and chinook (118 fish) salmon also were caught. In addition, 359 Dolly Varden (Salvelinus malma) were collected. Trap Net Index Sampling Trap nets were the primary sampling technique and proved to be effective at catching adult salmon. The sampling effort for the 6 index nets was uniform throughout the study period. Trap net fishing times for each net and week are summarized in Appendix B. Pink Salmon Pink salmon catch and catch-per-hour for each week and net are presented in Table 2. The catch-per-hour was low until the third week of August when numbers increased dramatically (Figure 4). Catch remained relatively high through the last week of the study. The maximum catch rate was reached in Week 6 at 0.389 fish per hour (Table 2). Chum Salmon Chum salmon catch was highest in mid-July during the first week of the study and declined precipitously after the end of July (Table 3 and Figure 5). The maximum catch rate occurred during the first week of the study at 0.281 fish per hour (Table 3). Coho Salmon Coho salmon (Table 4 and Figure 6) were first seen in the study area during Week 2 with catch rate increasing to a peak in mid- August and remaining high through the end of the study. The highest catch rate occurred during Week 5. Sockeye Salmon Sockeye salmon were present in the Bradley River during the entire study period (Table 5 and Figure 7) with the highest catch occurring during the mid- to late August period. 8 Chinook Salmon Chinook salmon were present in moderate numbers during Weeks 1 through 5 with highest numbers occurring during the first week of the study (Table 6 and Figure 8). Dolly Varden Dolly Varden were collected in trap nets during all weeks of the study with peaks of abundance occurring in late July and again in late August (Table 7 and Figure 9). Beach Seining Beach seine catch data are summarized for pink salmon in Table 8. A total of 211 pink salmon were caught by the beach seine in 1996, of which 43 were fish that had been tagged previously. Small numbers of the other salmon species as well as Dolly Varden were also caught in the seine. Carcass Counts The results of carcass counts are presented in Table 9. During the course of the 1996 study, 14 pink salmon carcasses, 23 chum salmon carcasses, 28 chinook salmon carcasses, and 11 sockeye salmon carcasses were observed in the study area. Fish Condition Pink Salmon The condition codes for all measured salmon are presented in Appendix A-1. Condition 3, "ripe", is indicative of spawning condition and was the least subjective of the condition codes since it depended on the actual presence of eggs or milt. Figure 10 9 shows the percent frequency of occurrence of Condition 3 fish for both male and female pink salmon. During the first four weeks o the study, few pink salmon were present in the river, consequently the frequency data for this period is probably not a reliable indication of salmon maturity. Most pink salmon entered the river in mid-August and Figure 10 indicates that nearly all the males and about half of the females were ripe at the time of entry. The peak of spawning probably occurred in Week 6 very soon after the fish reached the spawning grounds. The pattern observed in prior years of gradual maturation of females while in freshwater was not observed in 1996. Chum Salmon During the first week of the study in mid-July, 97 percent of the males were ripe and 77 percent of the females. During Week 2, 90 percent of the males and 73 percent of the females were ripe. After Week 2 few chum salmon were left in the river. It is likely that chums were at the peak of spawning at the time that the study started. Coho Salmon Coho salmon were first observed in the Bradley River on July 30, however no ripe fish were seen until August 20. Percentage ripeness for Weeks 5 through 8 was 7, 0, 21, and 39 percent, respectively. No ripe females were observed during the study period. The peak of coho spawning likely occurred well after the end of the study period in late September or early October. Sockeye Salmon Small numbers of sockeyes were present in the Bradley River throughout the entire study period. Percentages of ripe fish in Weeks 1 through 8 were 0, 14, 33, 63, 79, 85, 70, and 50 percent respectively, suggesting that spawning occurred over a prolonged 10 period with the peak occurring in late August. Chinook salmon During the first week of the study in mid-July all of the males and 57 percent of the females were ripe. In Weeks 2 and 3 essentially all of the fish were either ripe or spawned out. The number of chinooks present in the river decreased rapidly in Weeks 4 and 5 with no fish present after Week 5. Most spawning probably occurred early in the study period during the last two weeks of July. Stream Life Duration Pink Salmon Table 10 provides information on the tagging history of all pink salmon recaptured in trap nets. As has been the case in past years, most of the prior-weeks recaptures for any given week were fish that had been marked in the previous 2 weeks, suggesting an average stream life duration of about 2 weeks. Only one recaptured fish had been marked more than two weeks prior to capture. This fish was marked on August 20 and recaptured on September 11 for a stream life duration of at least 23 days. In general, the 1996 pink salmon run was very abrupt with most fish entering the river in Weeks 5 and 6 and spawning quickly thereafter. Chum Salmon Since the 1996 study began near the peak of chum salmon spawning, the information does not provide much insight into stream life duration for this species. Of 48 recaptured fish, none were recaptured more than 10 days after the marking date. Chinook Salmon The timing of the study period did not include the early part of 11 the chinook salmon run; consequently, stream life duration cannot be accurately determined. Twenty-four chinook salmon were recaptured in 1996, most of which had been tagged in Week 1 and recaptured in Week 2. Two fish were recaptured in Week 3 that had been tagged 16 days earlier. Spawning Area Location The unusually high turbidity during the 1996 study period prevented most visual observations of spawning fish. General observations suggested that spawning locations were similar to prior years with two exceptions: (1) chinook salmon were visually observed for the first time spawning in the south channel of Riffle Reach downstream from Net 7 (Figure 3); and (2) seine sampling at Tree Bar Reach (Site S1) indicated that sockeye salmon were intermingled with pink salmon on the Tree Bar spawning area. Fox Farm Creek Surveys During visual surveys conducted each week at Fox Farm Creek, only one adult salmon was observed: a tagged sockeye salmon carcass was found in the creek on September 11. The fish had been tagged at Site S1 in the Bradley River on August 27. Population Estimates Pink Salmon Weekly population estimates for pink salmon based on trap net recaptures using the same mark and recapture techniques employed in the 1986-1995 studies are presented in the first part of Table 11. Weekly population estimates ranged from a low of 85 in Week 2 to a high of 1000 in Week 5. Because of the small number of recaptures in all weeks, the 95 percent confidence limits (Table 11) for the estimates are broad and the statistical reliability of the estimates should be considered poor. 12 Population estimates also were calculated from selected seine hauls in Weeks 6 through 8 (Table 11). These estimates are also based on small numbers of recaptures and, thus, have broad confidence limits. Chum Salmon A mark-recapture population estimate was calculated for chum salmon in Week 2 as follows: Week Total Catch Tags Out Recaps. Pop. Est. 95% Limits 2 62 54 a7 193 128-351 Chinook Salmon A single estimate for Week 2 provides some insight into numbers of chinook salmon: Week Total Catch Tags Out Recaps. Pop. Est. 95% Limits 2 39 48 il 163 100-364 Estimates of Total Escapement Pink Salmon An estimate of the total escapement can be calculated from the weekly trap net population estimates for pink salmon using the method of Pirtle and McCurdy (1980). With this method the weekly estimates are summed and divided by a stream life factor of 2.5. Since there is no population estimate for Weeks 1 and 3, these populations were assumed to be equal to 10 times the total catch for the week, which is a highly conservative estimate of the actual numbers of fish present. Based on the above methodology, total escapement for pink salmon in the Bradley River in 1996 is estimated at about 1520 fish. 13 Another approach to escapement estimation is based on a comparison of the overall trap net catch-per-hour in 1996 compared to previous years. The year 1994 was used for comparison purposes because it is an even year with a low salmon population and the escapement estimate for that year is considered to be reasonably accurate. Reducing the 1994 escapement estimate to reflect the lower 1996 catch rate yields an estimated 1996 escapement of 2690 pink salmon. The relative accuracy of these various escapement estimates is examined below in the Discussion section. Chum Salmon The net catch of chum salmon in 1996 was 154 fish of which 32 percent were recaptures of fish caught previously. The mark- recapture estimate for Week 2 indicated that the number of chum salmon present in the river at that time probably fell into the range of 128-351 fish. An estimated total escapement of around 250 fish is reasonable, based on the 1996 catch statistics. Coho Salmon The study endea early in the coho run, therefore escapement cannot be estimated. The total net catch was 204 cohos, of which 9 percent were recaptures. It is likely that at least 300 cohos were present in the river at the time of the study. Sockeye Salmon A total of 309 sockeye salmon were caught during the study, of which 30 percent were recaptures. A conservative estimate of the number of sockeyes present in the Bradley River, based on observations during the 1996 season, is 400-500 fish. 14 Chinook Salmon Combining untagged captures with untagged carcasses results in a total of 117 individual chinook salmon that were handled during the study period. This represents the minimum number of fish present. The mark-recapture population estimate for Week 2 described above suggested that about 163 chinooks were present in the river at that time. A conservative estimate of the total escapement of chinooks in 1996 is 150-250 fish. Tag Returns From Outside the Study Area Two tagged fish were reported to the Alaska Department of Fish and Game in 1996. A coho salmon that was tagged in the Bradley River on August 13 was recovered by a sport fisherman at the Homer Spit lagoon on August 28. A second coho salmon that was tagged on August 22 was caught by a sport fisherman in the Homer Spit lagoon on September 2. Minnow Trap Sampling The ten minnow traps caught 105 juvenile chinook salmon, 74 coho salmon, 31 Dolly Varden, and 46 sculpins (Table 12). Most of the juvenile cohos were caught in two ponds within Bear Island Slough. These ponds were isolated from the main river at the time of sampling but become connected during high water periods. Chinook salmon were commonly found within the main channel of the Bradley River and in some backwater areas. Field differentiation between juvenile coho and chinook salmon in the Bradley River is difficult and some mistakes in identification were likely made. Length frequency analysis of the juvenile salmon (Figure 11) suggests that two age groups of chinooks and possibly two age groups of cohos were present. The length analysis indicates that some Bradley River chinooks spend two years in freshwater prior to outmigration. 15 Physical Data Air and water temperature, turbidity, and relative water level data are presented in Appendix C. Temperature data were collected at about 8:00 a.m. and, thus, are approximately representative of daily minimums. Water temperature showed relatively little variation, ranging from 7.9 to 10.7 degrees C. Predominantly cloudy weather combined with minimal air temperature extremes contributed to the stable stream water temperature regime. Turbidity was consistent and very high compared to previous years, ranging from a low of 104 NTU on September 12 to 134 NTU on July 31. Minimal snowfall during the winter of 1995-96 and low precipitation during the study period contributed to generally dry conditions in the Bradley River drainage. Nearly all the water in the lower Bradley River was contributed by release from the fishwater bypass at the Bradley Lake dam and, thus, contained high glacial sediment load. Clear water contributions from ground water and/or the North Fork drainage were significantly less than in prior years. River water level was very stable throughout the study period varying by less than 1.5 inches, again reflecting the release of a nearly constant amount of water from the dam. Miscellaneous Observations A new eagle nest was noted in a live cottonwood on the east side of the Bradley River about 200 ft. downstream from Net 4. The nest was probably built by the same pair of eagles that utilized the nest at Eagle Pool in 1994 and 1995. The new nest is about 1000 ft. upstream from the old nest. Two young eagles fledged from the nest in late August. Overall eagle activity was relatively low along the river in 1996, probably reflecting the generally low population of pink salmon. Bear signs were observed intermittently throughout the study period. Individual black bears were sighted on August 20 and September 9. A bear excavated a bee’s nest near Fish Camp during 16 the night of August 19. Other observations included: 1. A boreal owl was observed and heard frequently in the Fish Camp area between August 6 and August 27. 2. A river otter was observed near Net 5 on August 14. 3. Harbor seals were observed as far upstream as Net 5 during extreme tides on July 31 and August 1. DISCUSSION Validity of Abundance Indices and Estimates The potential difficulties with the use of mark and recapture population estimates under the circumstances in the Bradley River are discussed in detail in the 1986 study report (Alaska Power Authority 1986b). The analysis of marking net vs. recapture net presented in the 1989 study report (Northern Ecological Services 1989) indicates that pink salmon move widely throughout the study area prior to actual spawning and provides some assurance that the assumption that tagged fish are randomly distributed is not grossly violated. It should be noted that all of the "capture" methods were biased in favor of specific components of the pink salmon population. The trap nets sampled fish that were actively moving within the river and tended to catch more males than females. Seining in the latter part of the study period sampled fish that were actively spawning and usually included a more equal sex distribution than the trap net fish. Because of the generally low number of pink salmon and the small number of recaptures, population estimates in 1996 should be viewed very carefully. Statistical confidence limits are broad. Additionally, the run was unusually late and abrupt in 1996; most fish entered the stream in Week 5 and spawned quickly thereafter. The rapid influx followed by rapid mortality significantly violates the assumption of a closed population which is required for a7 accurate mark-recapture estimates. Nevertheless, trap net and seine estimates for Weeks 6-8 are relatively consistent and are probably reasonably reflective of numbers of fish in the river at that time. The shortened 1996 study period (8 weeks compared to 9 weeks in prior years) combined with the abrupt, late run contributed to difficulty in estimating overall escapement for pink salmon. Stream life duration may have been shorter in 1996 than in most other years and the stream life factor that has been used in the past (2.5 weeks) may be too large for application to 1996 conditions. The 1996 study period did not encompass the end of the spawning period and, thus, escapement estimates based on only 8 weeks probably underestimated actual fish numbers. However, applying various correction factors to compensate for shorter stream life or longer study duration results in only small changes in escapement estimates. For example, if stream life is shortened to 2.0 weeks and a hypothetical ninth week is added to the study period at the same population level as the eighth week, the resulting escapement estimate is about 2400 fish. It can be concluded with certainty that the number of pink salmon in the Bradley River in 1996 was small relative to numbers seen in odd years. The various escapement estimation techniques suggest an escapement in the range of 1500-3000 fish with 2000 being a reasonable intermediate approximation. Comparison With Prior Years Pink Salmon Figure 12 compares the overall catch-per-hour and estimated total escapements for the years 1986 through 1996. The 1996 catch rate, while low, was somewhat above average for even numbered years, excluding 1986. It is thought that extreme flooding in the fall of 1986 destroyed most of the salmon eggs that were in the river at that time, thus causing subsequent even year runs to be low 18 because of the two-year life cycle of pink salmon. Wild pink salmon returns to Kachemak Bay streams and Lower Cook Inlet as a whole were generally poor in 1996; Humpy Creek, the largest pink salmon producer in Kachemak Bay, fell well short of its escapement goal (L. Hammarstron, ADF&G, personal communication). Returns of hatchery pinks to Tutka Bay were also low, about 1/3 of the forecast numbers (Hammarstrom, ADF&G, Personal Communication). The low hatchery return suggests that saltwater survival was poor for pink salmon released in 1995 and returning in 1996. Numbers of pink salmon observed in the Bradley River appeared to be reflecting area-wide trends. Chum Salmon The catch rate for chum salmon in the Bradley River in 1996 was intermediate compared to past years (Figure 13). Estimated chum salmon escapements have varied from 50 fish to 1600 fish since 1986 with 3 years having escapements of greater than 500 fish. The approximately 250 fish present in 1996 is somewhat above average for post-project years. Chum salmon returns in general to Southern Cook Inlet streams were low in 1996 (L. Hammarstron, ADF&G, personal communication), consequently the relatively low number in the Bradley River is consistent with area trends. Coho Salmon Study timing in 1996, as well as in previous years, has prevented estimates of coho salmon escapement and meaningful comparisons are difficult. The 1996 trap net catch rate was the second highest since the beginning of the study program in 1986 and probably reflects an unusually high population (Figure 14). The 1996 spawners were probably the result of eggs spawned in 1992 and/or 1993. Since the 1992 and 1993 spawning runs were small, survival under the regulated flow regime was evidently good. Coho salmon returns to south-central Alaska streams were generally above 19 average in 1996 (L. Hammarstrom, ADF&G, personal communication), consequently the above average return to the Bradley River is consistent with area trends. Sockeye Salmon The number of sockeyes caught in 1996 was by far the highest since the Bradley River salmon escapement study program began in 1986 (Figure 15). Sockeye salmon were observed spawning in the same areas and at the same time as the pink salmon. There has been question in the past regarding whether sockeye salmon in the Bradley River represent a self-sustaining population. Evidence is mounting that the river supports a small run of sockeyes that has become established in the last ten years. Survival appears favorable under the regulated flow regime. Chinook Salmon The catch-per-hour for chinook salmon in 1996 was the highest since the beginning of the study (Figure 16). Since the 1996 study began later than in past years, during the chinook spawning period, it is likely that the overall catch rate underestimates the relative abundance of fish in 1996. Success of chinook salmon under the regulated flow regime appears to be very good based on the 1995 and 1996 returns. Minnow Trap Catch The catch-per-hour for juvenile chinook salmon in the minnow traps (excluding Traps 4 and 5 in isolated ponds) was 0.66 fish in mid- September of 1996. A similar study conducted in mid-July of 1994 (Alaska Energy Authority 1994) resulted in a catch of 0.26 chinooks per hour for traps in roughly the same locations. While study timing is somewhat different for the two efforts, it appears that density of juvenile chinook was substantially higher in 1996 than 1994, 20 ACKNOWLEDGEMENTS We would like to thank the Homer Electric Association Bradley Lake Hydroelectric Project field staff for their cooperation and logistical support of the field crew during the course of the field study.
