AbstractThe process of sexual differentiation (i.e. development of ovaries or testes) in fishes is much more plastic than it is for humans or other mammals. Even in fish species for which genetic sex determination systems have been well described, exogenous factors such as high temperature or steroid exposure may override those genetic controls and induce sex reversal—a mismatch between genetic and phenotypic sex. Sablefish Anoplopoma fimbria, also known as black cod (or “gindara” in Japan), is an important United States fishery and emerging marine aquaculture species, and a focal species for intensive aquaculture research and development at the Northwest Fisheries Science Center (NWFSC, Seattle, Washington, USA). Upon initiating our work with sablefish, we recognized that it exhibits sexually dimorphic growth, with females growing significantly faster and attaining a larger body size than males, a phenomenon seen in many other species as well. This led to a major goal to develop a non-GMO met
