摘要

A fish weir equipped with an underwater video system was installed and operated between 29 April and 5 August in the Funny River during 2008 to collect abundance, run timing, and biological information on adult Chinook salmon Oncorhynchus tshawytscha and steelhead O. mykiss. A total of 1,246 Chinook salmon and 187 steelhead was counted past the Funny River weir between 30 April and 4 August. Non-target species enumerated included 303 Dolly Varden Salvelinus malma, 177 pink salmon O. gorbuscha, 52 sockeye salmon O. nerka, 58 rainbow trout O. mykiss, 14 round whitefish Prosopium cylindraceum, 5 lamprey Lampetra spp., 1 coho salmon O. kisutch, and 1 chum salmon O. keta. Peak weekly passage of Chinook salmon and steelhead occurred between 13 and 19 July and 4 and 10 May, respectively. Age, sex, and length information was collected from 128 Chinook salmon and 14 steelhead. Sex of both species was also determined by examining recorded video records.
