Abstract
The necessity of control of selective characteristics in fishery and the results of selective opera-tion of instruments of catch and fishery is studied. The techniques of control are considered. The operations for intensive catch taking into account only selectivity of net bags as two components that help estimate the influence of catch selectivity on intensity of the catch and compare it with the influence of the catch intensity while nonselective fishing are closely studied. The mutual influence of selectivity and intensity of fishing on efficiency of fishing gear as a factor of fishing productivity is considered.
