Acipenser naccarii is a critically endangered [Z] species of the sturgeon family. It was probably driven to extinction in the wild due to overfishing and was preserved solely due to the efforts of regional governments and fish farms (one in Italy and the other in Spain) that started a reproduction programme [Z] [Z]. Nowadays its production efforts are divided between repopulation and caviar. A minor percentage is hybridised with Acipenser baerii for meat production [Z]. It is however surprising that almost no information on the biology of this species is available and therefore neither a clear assessment of its current welfare state nor potential for improvement is possible. Further research should be dedicated to all the criteria evaluated on the list below as well as the success of the repopulation effort.
