Title:

G: 162 - Abundance and Migration of Juvenile Salmonids in Study Streams During Migration Year 2007

Description:

Data collected during project activities will be used to estimate abundance and in-subbasin migration patterns for juvenile spring Chinook salmon and summer steelhead in the four study streams of Catherine Creek, upper Grande Ronde River, Lostine River, and Minam River.

Migration timing to Lower Granite Dam of fish tagged in summer, fall, winter and spring, under Work Element E: Mark/Tag Fish, will be analyzed and compared by time of tagging, species and migratory year. In this performance period we will tag spring Chinook salmon and summer steelhead that will migrate to the ocean or be detected across multiple migration years. For example, migrants tagged in spring 2007 will migrate to the ocean in spring 2007, whereas the migrants tagged in the fall of 2007 will not migrate to the ocean until spring of 2008. Therefore, fish tagged in fall under the FY 2006 performance period will be analyzed along with the fish tagged in spring under this performance period, and likewise fish tagged in fall under this performance period will be analyzed along with the fish tagged under the FY 2008 performance period. Given the diversity of summer steelhead migration tactics, tagged fish may include small proportions of fish tagged during as many as three performance periods.

WE Agreement Type:

Contracted

Deliverable Specification:

• Estimate the minimum number of juvenile spring Chinook salmon and summer steelhead that emigrated from rearing areas above trapping locations in each of the four study steams, based on the number of each species collected in rotary screw traps and species specific trap efficiency estimates in each of four study streams.
• Describe the in-subbasin migration patterns of juvenile spring Chinook salmon and summer steelhead in each of four study streams.
• Determine migration timing to Lower Granite Dam by juvenile spring Chinook salmon and summer steelhead. Migration timing data will be assessed using Kruskal-Wallis test on ranks of dates of detection.
• Characterize the cohort size of spring Chinook salmon and size and age of summer steelhead for each study stream. Descriptive statistics (such as mean, range, and standard error) will be used to characterize the length of spring Chinook salmon and summer steelhead collected during migration and rearing phases. Ages of steelhead sampled for scales will be determined and used to construct an age/length key to be used with a length frequency histogram of summer steelhead to determine the proportional distribution by age for migrants collected at rotary screw traps in each of four study streams.

		Description: Estimates of spring Chinook salmon and summer steelhead migrants are based on the number of each species collected in rotary screw traps and species specific trap efficiency estimates in each of four study streams. Estimates will be summarized by migratory year in order to maintain biological relevance.

		Description: For each trap location, plot estimated number of migrants against time of year to determine timing and duration of juvenile migration periods.

		Description: Plot the number and migration timing for PIT-tagged spring Chinook salmon and summer steelhead from each of four study streams that were detected migrating to Lower Granite Dam. Migration timing data will be assessed using Kruskal-Wallis test on ranks of dates of detection.
