A minimally invasive method for extraction of sturgeon oocytes
James S. Candrl, Diana M. Papoulias, Donald E. Tillitt
2010, North American Journal of Aquaculture (72) 184-187
Fishery biologists, hatchery personnel, and caviar fishers routinely extract oocytes from sturgeon (Acipenseridae) to determine the stage of maturation by checking egg quality. Typically, oocytes are removed either by inserting a catheter into the oviduct or by making an incision in the body cavity. Both methods can be time-consuming and...
