Table A1. The results of a fall Chinook salmon (Oncorhynchus tshawytscha) passage and handling study conducted in November, 2014, at the Priest Rapids Salmon Hatchery, Mattawa, Washington. Each adult salmon was given a Passive Integrated Transponder (PIT) tag with a unique identification code (column: PIT tag number). Their gender was determined (column: Sex with M = male and F = female). Fork length was measured in cm (column: Length), body circumference was measured in cm (column: Circumference), and body weight taken in kg (column: Weight). Fish were divided into one of four treatment groups (column: Treatment) – Whoosh Fish Transport System (WFTS) 77 m tube (WFTS-77), WFTS 12 m tube (WFTS-12), trap and haul (T&H), or control. Treatment dates (column: Treatment date) ranged from November 4-6, 2014 and mortality dates (column: Mortality date) ranged from November 4-11, 2014. The following information was collected on a subset of fish – column: Spleen IL1-β normalized with 18s (n = 65); column: Spleen IgM normalized with 18s (n = 65); column: Cortisol concentration (ng/mL) (n = 41); column: Day 3 vitellogenin concentration (mg/mL) (n = 63); and column: Percent epithelial injury (%) (n = 42). In all columns, NR represents no data were recorded. Table A2. The gamete survival results from a study on the effects of passage and handling conducted in 2014 with adult fall chinook salmon (Oncorhynchus tshawytscha) that were captured at Priest Rapids Salmon Hatchery, Mattawa, Washington. Each fish was given a Passive Integrated Transponder (PIT) tag with a unique identification code (column: PIT tag number). Fish were divided into one of four treatment groups (column: Treatment) – Whoosh Fish Transport System (WFTS) 77 m tube (WFTS-77), WFTS 12 m tube (WFTS-12), trap and haul (T&H), or control. Their gender was determined (column: Sex with M = male and F = female). One female’s eggs were fertilized with sperm from one male (column: Pair number) for a total of 37 pairings (i.e., sib family). The fertilized eggs were divided into three sub-samples per family (approximately 100 eggs per sub-sample) and randomly assigned to a stack, tray and cell in vertical flow incubators. Fertilized eggs were held in incubation trays at ~10°C until they reached the eyed egg stage (December 17, 2014, or approximately 40 days post-fertilization), at which time the number of live and dead eggs were counted to determine gamete survival by cell (columns labeled 1st cell survival, 2nd cell survival, and 3rd cell survival, all percentages). Data analysis was done on the average embryo survival to the eyed stage (subsamples were averaged per sib family) (column: Average survival %)
