Fresh Salmon and Eggs
It’s a mystery that has puzzled University of Maine assistant professor of marine biology and aquaculture Heather Hamlin and the salmon farming industry in New England: the decline in egg survival. The survival rate of fertilized salmon eggs had been as high as 80 percent. Beginning in 2000, salmon embryos began dying in large numbers and the average survival rate fell to 50 percent. Now a study has found that two hormones may play significant roles in achieving an 80 percent embryo survival rate.
