Attempts to Acclimate Embryos and Alevins of Atlantic Salmon, Salmo salar , and Rainbow Trout, S . gairdneri , to low pH

Embryos and alevins from three strains of Atlantic salmon, Salmo salar, and one strain of rainbow trout, S. gairdneri, were tested for low pH tolerances following exposures at several pH values. Acclimation to low pH, judged by resistance adaptation, did not occur. Alevins had 10 000 min LL 50 '...

Description
Summary:Embryos and alevins from three strains of Atlantic salmon, Salmo salar, and one strain of rainbow trout, S. gairdneri, were tested for low pH tolerances following exposures at several pH values. Acclimation to low pH, judged by resistance adaptation, did not occur. Alevins had 10 000 min LL 50 's for pH of about 4.3 for all strains and were less tolerant than embryos.Key words: pH, acclimation, Atlantic salmon, rainbow trout, embryo, alevin
