OPTIMIZATION OF QUALITATIVE CHARACTERISTICS OF FISHING LOAD IN THE KAKHOVKA RESERVOIR

Based on the analysis of current biological state of some species of the Kakhovka reservoir, there have been determined indices, which characterized the efficiency of commercial exploitation of their stocks. We assessed specific accumulation of crucian carp and pikeperch ichthyomass by age groups. Based on the data of catch distribution by mesh size in fishing gears and age-size structure of crucian carp and pikeperch populations, we proposed measures on optimization of qualitative characteristics of the technical base of fish harvest in the Kakhovka reservoir.
