Fish (Osteichthyes) in Biesbosch storage reservoirs (the Netherlands): a method for assessing complex stocks of fish

Original language description

A new method of habitat volume and CPUE weighting of gillnet catches is proposed and reasonable correspondence was found between the length and weight compositions of acoustic and netting results. The fish stock in three Biesbosch reservoirs (the Netherlands) was studied using an echosounder, Nordic multi mesh gillnets, fry trawling and beach and purse seining. There were up to 11 benthic and open water habitats in the reservoirs based on the depth and slope of the bottom. All these habitats were inhabited by fish but differed in terms of the relative abundance, age and species present, volume and importance. The fish stock can be characterized as a smelt-pikeperch system. In addition to European smelt, important prey fish are common bream and roach. The survival rates of the prey fish were extremely low. The survival rate of percid fish (European perch, pikeperch and ruffe) was much higher. Lack of cyprinid reproduction and a high natural mortality keep the total biomass of fish at le
