This study aims to highlight new information on histology of sturgeons in general and of sterlet in particular. Some organs, such as: the esophagus, the stomach, the anterior intestine, the posterior intestine, pyloric caeca, the liver, the pancreas, gonads and the gills were observed under the microscope. Samples from 11 months old sterlets were taken from different individuals that were in full growth in a recirculated aquaculture system. Cultured in these conditions, it appears that the sterlet is developing harmonious. The proofs are the large spaces between the muscular fibers, both smooth and ribbed. Source

The research had the purpose to establish if the wels catfish is suitable for growing in closed recirculated system designed for sturgeon farming, because during the cold season the system does not need to reach high temperatures such as for other fish species. Our studies showed that the wels catfish can survive during the cold season from a recirculated system, and furthermore they accept feeds at temperatures as low as 17°C, and even have a slight body weight increase during this season. The wels catfish entered the spring in our experiment at a mean body weight of 72.5 grams, while the wels catfish from semi-intensive system after wintering in earthern ponds entered the winter at a mean body weigh of 30 grams. Our experiments also studied the effect of stocking density on fish development in these conditions. Source
