Comparing Ultrasonography and Endoscopy for Early Gender Identification of Juvenile Siberian Sturgeon
Abstract Early gender identification is economically advantageous in sturgeon aquaculture to facilitate the targeting of food and spatial resources to females for caviar production. In addition, many species of free‐ranging sturgeon are threatened or critically endangered, and the ability to identif...
