Sex control experiments - Development of methods to sterilize sablefish

Description

Methods for reproductive sterilization are broadly needed in marine aquaculture due to biosafety concerns associated with escapement of farmed fish and potential genetic contamination of wild stocks. Current methods for sterilization have been primarily tested in freshwater fishes and are often ineffective, particularly in males. The proposed activity builds upon our recent success in producing the first-ever monosex female stocks of sablefish for aquaculture and seeks to develop eco-friendly, non-GMO methods for reproductive sterilization. We will use sablefish as our model marine species for sterilization and continue to collaborate with University of Maryland faculty with expertise in cutting-edge techniques for sterilization. Development of sustainable marine aquaculture is a high priority at the local (NWFSC), regional (WCR), and national levels (NOAA, DOC, Congress). Our sablefish sex control/sterilization project was also highlighted as a critical priority and outstanding area of research in the NOAA Aquaculture Science Review published 28 Feb 2019. We ultimately aim to transfer a sterilization technology to the US sablefish aquaculture industry and expand our methodology to other important species, with the goal of improving sustainability of marine aquaculture and mitigating impacts on the environment. In these experiments sablefish sex ratio data are collected using gonadal histology and a genetic sex marker.
