Kruchinin, O.N. | Babenko, V.S.
The possible ways of fish exit from zone of catching by purse seine are considered and the formulas for account of probability of catching fishes in process encircles and purse the net are deduced. Is shown, that the probability of catching depends on speed of immersing the bottom line of purse seine. The technique of account of immersing of various sites of the bottom line is offered, and the dependence of probability of catching from the form encircles, size and speed of fish jamb movement is determined. The convergence of the theoretic data with the data of experimental observations on catching sardine by purse seine is shown. The received results can be used for a tentative estimation of productivity of purse seine, and also for perfection of imitating models, on the basis of which are developed imitators of processes of catching by purse seine
