This book was released on 1994 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lower Granite Dam on the Snake River to evaluate the feasibility of using video technology to document and estimate fish ladder passage of chinook salmon Oncorhynchus tshawytscha, sockeye salmon O. nerka, and steelhead O. mykiss. A video system was to produced video images during salmon passage periods. A technician identified and counted fish images from the video record. Fish ladder passage estimates of target species made from the video record were similar to estimates made by on-site counters during daytime periods, indicating that the two methods were relatively precise. We also found that a significant percentage (6.4% and 8.3%) of target salmonids migrated during nighttime periods when on-site counts were not typically made during the two years of study. Analysis of the video record permitted verification of individual sockeye salmon identified and counted by on-site count personnel, and provided data useful to managers of this ESA-listed stock. Analysis of the video record also permitted collection of additional data such as length measurements of individual specimens, which was used to regulate a fishery located upstream.

This book was released on 1993 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field study was conducted at Lower Granite Dam on the Snake River in 1992 to evaluate the feasibility of using time-lapse video technology to document and estimate fish ladder passage of chinook salmon Oncorhynchus tshawytscha, sockeye salmon 0. nerka, and steelhead 0. mykiss using time-lapse video technology. High quality video images were produced with a time-lapse video system operating in 72 h mode from 1 May through 31 December, 1992 and fish were counted from 1 June through 15 December. From the video record we counted 15 sockeye salmon, 3,283 summer chinook salmon, 1,022 fall chinook salmon, and 125,599 steelhead. The composite count of target species generated from the video record was similar (p = 0.617) to the estimate made by on-site counters during identical time periods indicating that the two methods were precise. Comparisons of 24 h video counts and on-site (10 and 16 h) counts showed that a significant (p

This book was released on 2003 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1995, the Chief Joseph Kokanee Enhancement Project was established to mitigate the loss of anadromous fish due to the construction of Chief Joseph and Grand Coulee dams. The objectives of the Chief Joseph Enhancement Project are to determine the status of resident kokanee (Oncorhynchus nerka) populations above Chief Joseph and Grand Coulee dams and to enhance kokanee and rainbow trout (Oncorhynchus mykiss) populations. Studies conducted at Grand Coulee Dam documented substantial entrainment of kokanee through turbines at the third powerhouse. In response to finding high entrainment at Grand Coulee Dam, the Independent Scientific Review Panel (ISRP) recommended investigating the use of strobe lights to repel fish from the forebay of the third powerhouse. Therefore, our study focused on the third powerhouse and how strobe lights affected fish behavior in this area. The primary objective of our study was to assess the behavioral response of kokanee and rainbow trout to strobe lights using 3D acoustic telemetry, which yields explicit spatial locations of fish in three dimensions. Our secondary objectives were to (1) use a 3D acoustic system to mobile track tagged fish in the forebay and upriver of Grand Coulee Dam and (2) determine the feasibility of detecting fish using a hydrophone mounted in the tailrace of the third powerhouse. Within the fixed hydrophone array located in the third powerhouse cul-de-sac, we detected 50 kokanee and 30 rainbow trout, accounting for 47% and 45% respectively, of the fish released. Kokanee had a median residence time of 0.20 h and rainbow trout had a median residence time of 1.07 h. We detected more kokanee in the array at night compared to the day, and we detected more rainbow trout during the day compared to the night. In general, kokanee and rainbow trout approached along the eastern shore and the relative frequency of kokanee and rainbow trout detections was highest along the eastern shoreline of the 3D array. However, because we released fish near the eastern shore, this approach pattern may have resulted from our release location. A high percentage of rainbow trout (60%) approached within 35 m of the eastern shore, while fewer kokanee (40%) approached within 35 m of the eastern shore and were more evenly distributed across the entrance to the third powerhouse cul-de-sac area. During each of the strobe light treatments there were very few fish detected within 25 m of the strobe lights. The spatial distribution of fish detections showed relatively few tagged fish swam through the center of the array where the strobe lights were located. We detected 11 kokanee and 12 rainbow trout within 25 m of the strobe lights, accounting for 10% and 18% respectively, of the fish released. Both species exhibited very short residence times within 25 m of the strobe lights No attraction or repulsion behavior was observed within 25 m of the strobe lights. Directional vectors of both kokanee and rainbow trout indicate that both species passed the strobe lights by moving in a downstream direction and slightly towards the third powerhouse. We statistically analyzed fish behavior during treatments using a randomization to compare the mean distance fish were detected from the strobe lights. We compared treatments separately for day and night and with the data constrained to three distances from the strobe light (

Book excerpt: The concept of using mass releases of juvenile radio tags represents a new and potentially powerful research tool that could be effectively applied to juvenile salmonid passage problems at dams on the Columbia and Snake Rivers. A system of detector antennas, strategically located, would automatically detect and record individually tagged juvenile salmonids as they pass through the spillway, powerhouse, bypass system, or tailrace areas below the dam. Accurate measurements of spill effectiveness, fish guiding efficiency (FGE), collection efficiency (CE), spillway survival, powerhouse survival, and bypass survival would be possible without handling large numbers of unmarked fish. A prototype juvenile radio-tag system was developed and tested by the National Marine Fisheries Service (NMFS) and Bonneville Power Administration (BPA) at John Day Dam and at Lower Granite Dam. This report summarizes research to: (1) evaluate the effectiveness of the prototype juvenile radio-tag system in a field situation and (2) to test the basic assumptions inherent in using the juvenile radio tag as a research tool.

Download or read book Smolt Monitoring at the Head of Lower Granite Reservoir and Lower Granite Dam, 2002 Annual Report written by and published by . This book was released on 2009 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project monitored the daily passage of Chinook salmon Oncorhynchus tshawytscha, steelhead trout O. mykiss, and sockeye salmon smolts O. nerka during the 2002 spring out-migration at migrant traps on the Snake River and Salmon River. In 2002 fish management agencies released significant numbers of hatchery Chinook salmon and steelhead trout above Lower Granite Dam that were not marked with a fin clip or coded-wire tag. Generally, these fish were distinguishable from wild fish by the occurrence of fin erosion. Total annual hatchery Chinook salmon catch at the Snake River trap was 11.4 times greater in 2002 than in 2001. The wild Chinook catch was 15.5 times greater than the previous year. Hatchery steelhead trout catch was 2.9 times greater than in 2001. Wild steelhead trout catch was 2.8 times greater than the previous year. The Snake River trap collected 3,996 age-0 Chinook salmon of unknown rearing. During 2002, the Snake River trap captured 69 hatchery and 235 wild/natural sockeye salmon and 114 hatchery coho salmon O. kisutch. Differences in trap catch between years are due to fluctuations not only in smolt production, but also differences in trap efficiency and duration of trap operation associated with flow. The significant increase in catch in 2002 was due to a 3.1 fold increase in hatchery Chinook production and a more normal spring runoff. Trap operations began on March 10 and were terminated on June 7. The trap was out of operation for a total of four days due to mechanical failure or debris. Hatchery Chinook salmon catch at the Salmon River trap was 4.2 times greater and wild Chinook salmon catch was 2.4 times greater than in 2001. The hatchery steelhead trout collection in 2002 was 81% of the 2001 numbers. Wild steelhead trout collection in 2002 was 81% of the previous year's catch. Trap operations began on March 10 and were terminated on May 29 due to high flows. The trap was out of operation for four days due to high flow or debris. The increase in hatchery Chinook catch in 2002 was due to a 3.1 fold increase in hatchery production and differences in flow between years. Changes in hatchery and wild steelhead catch are probably due to differences in flow between years. Travel time (d) and migration rate (km/d) through Lower Granite Reservoir for PIT-tagged Chinook salmon and steelhead trout marked at the Snake River trap were affected by discharge. Statistical analysis of 2002 data detected a relation between migration rate and discharge for hatchery and wild Chinook salmon. For hatchery and wild Chinook salmon there was a 4.7-fold and a 3.7-fold increase in migration rate, respectively, between 50 and 100 kcfs. For steelhead trout tagged at the Snake River trap, statistical analysis detected a significant relation between migration rate and Lower Granite Reservoir inflow discharge. For hatchery and wild steelhead trout, there was a 1.8-fold and a 1.7-fold increase in migration rate, respectively, between 50 and 100 kcfs. Travel time and migration rate to Lower Granite Dam for fish marked at the Salmon River trap were calculated. Statistical analysis of the 2002 data detected a significant relation between migration rate and Lower Granite Reservoir inflow discharge for wild Chinook salmon and hatchery steelhead trout. The analysis was unable to detect a relation between migration rate and discharge for hatchery Chinook salmon. The lack of a detectable relation was probably a result of the migration rate data being spread over a very narrow range of discharge. Not enough data were available to perform the analysis for wild steelhead trout. Migration rate increased 4.3-fold for wild Chinook salmon and 2.2-fold for hatchery steelhead between 50 kcfs and 100 kcfs. Fish tagged with passive integrated transponder (PIT) tags at the Snake River trap were interrogated at four dams with PIT tag detection systems (Lower Granite, Little Goose, Lower Monumental, and McNary dams). Because of the addition of the fourth interrogation site (Lower Monumental) in 1993 and the installation of the Removable Spillway Weir at Lower Granite Dam in 2000, caution must be used in comparing cumulative interrogation data. Cumulative interrogations at the four dams for fish marked at the Snake River trap were 61% for hatchery Chinook, 68% for wild Chinook, 58% for hatchery steelhead, and 62% for wild steelhead. Cumulative interrogations at the four dams for fish marked at the Salmon River trap were 51% for hatchery Chinook, 59% for wild Chinook salmon, 45% for hatchery steelhead trout, and 54% for wild steelhead trout. Cumulative interrogations were significantly lower in 2002 than in previous years with similar flow.
