Study finds hormones may contribute to higher rate of salmon embryo survival, WABI reports
A University of Maine study led by Heather Hamlin, an assistant professor of aquaculture and marine biology, has found high levels of two hormones in female, farm-raised Atlantic salmon may contribute to higher survival rates in their offspring, WABI (Channel 5) reported. Hamlin has been investigating why average salmon embryo survival has dropped from as high as 80–95 percent to 50 percent over the past 15 years. “We believe the endocrine system is involved because of this really high correlation,” Hamlin told WABI. “And so now what we’re hoping to do is do some other genetic work and follow that up and try and understand other mechanisms that might be involved.” Mainebiz, FIS and Undercurrent News also reported on the study, and Phys.org published the news release.
