Determination of limits for catches of roach, bream, zander and carp in Zaporizhzhiya (Dnipro) water reservoir for 2018
Journal Title: Водні біоресурси та аквакультура - Year 2017, Vol 2, Issue
Abstract
The analysis of the current state of roach, straw, bream zander and silver bream populations of the Zaporizhzhya (Dnipro) reservoir was carried out and the size of the admissible industrial extraction of these fish species in 2018 was determined due to the determination of reasonable limits. In the course of the work, the generalized results of ichthyological studies in the water area of the Zaporizhzhya (Dnipro) reservoir during 2010–2017 were used. The basic biological indicators of these fish species were determined, the age and sex structure of the populations were determined, and the values of the industrial reserve were calculated. Basing on the obtained data, the coefficients of natural, industrial and total mortality were determined. The values of the limits of industrial catch of experimental species of fish are calculated.
