Developmental structure of the vertebral column, fins, scutes and scales in bester sturgeon, a hybrid of beluga Huso huso and sterlet Acipenser ruthenus
In the larval bester, a hybrid sturgeon of beluga Huso huso and sterlet Acipenser ruthenus , development of cartilage around the notochord began 7 days post hatch (dph) (14·0 mm, total length, L T ). The vertebral cartilage develops in the following sequence: basidorsals and basiventrals, neural can...
