Differentiated catchability of trawls as a method for a more precise estimate of density of krill swarms and its biomass
Abstract: Krill escapement in different parts of krill trawls and their differentiated ... considerable importance for catching results. It is proved that the estimation of density and size structure of ... fished krill swarms should be performed on the based of differentiated catchability of krill trawls. A ... mathematical model of krill trawling has been developed for estimating the above values. Author(s): V. Akishin ...
