Osmotic and ionic regulation in embryos, alevins, and fry of the five species of Pacific salmon
The physiological basis of the differences in the early life histories of pink (Oncorhynchus gorbuscha), chum (O. keta), coho (O. kisutch), chinook (O. tshawytschd), and sockeye (O. nerka) were examined.The LD 50 values indicated that the embryos and alevins of the five species are stenohaline; that...
