Title: Development of Rations for the Enhanced Survival of Salmon, 1985-1986 Progress (Annual) Report.

Abstract

This investigation tests the hypothesis that ration protein quality can influence the survival of smolts and the ultimate return of adults. The general approach being used involves a comparison of coho and chinook salmon reared on rations containing very high quality protein derived from vacuum dried meals and commercial rations relying on commercial fish meal as a source of protein. Survival and return of replicate brood-years of coded wire tagged test and control fish are being used to determine the influence of ration on survival. Project rearing and release of tagged fish to date include 1982, 1983, and 1984-brood replicates of coho salmon; the 1983 and 1984-brood replicates of fall chinook (tule stock salmon; and the 1985-brood of fall chinook (up-river-bright stock) salmon. The 1985-brood year replicate of coho salmon is presently being reared and has been tagged for release in April 1987. The rearing of the 1986-brood replicate of fall chinook (up-river-bright stock) salmon has been initiated. This report covers the rearing and release of the 1984-brood coho and the 1985-brood fall chinook (up-river-bright stock) salmon. Plasma cortisol and thyroxine (T/sub 4/) level, gill Na/sup +//K/sup +/-ATPase, osmoregulatory performance, immunocompetency and total hepatic/gill microsomal lipid content were monitored frommore » early June to mid-October 1986 to assess the physiological condition of fall chinook salmon. Results indicated that on several sampling dates early in the 1986 rearing period fish supplied the control ration were physiologically different than fish receiving the salmon meal ration. Incomplete recovery of coded wire tags from 1982 and 1983-broods of coho salmon (Sandy stock) revealed an improved (P greater than or equal to .05) survival for fish supplied test rations.« less
