Reproductive Cycles in Sturgeons with a Special Focus on the Farmed Siberian Sturgeon

2017
The chapter reports the published data on biological cycles and/or puberty in sturgeons for both wild and farmed brood stocks. There are three main lines to document these data, the analysis of large-scale sampling or landings, the analysis of sampling with previously tagged fish and the echography which has a remarkable efficacy.
