Abstract
At 8–9 C, sockeye ova without added water maintained their initial fertility for 12 hr and a few were still fertile after 175 hr; sockeye milt maintained its initial fertility for 11 hr, and fertilized a few ova after 101 hr. Pink salmon ova maintained their initial fertility for 8 hr and some were still fertile at 129 hr; pink salmon milt maintained its initial fertility for 33 hr and fertilized 67% of the test ova at 57 hr, but none at 81 hr. Comparison of these results with those of tests at lower storage temperatures suggests that cooler storage would extend the period of high fertility.This publication has 1 reference indexed in Scilit:
