СТРУКТУРНI ПОКАЗНИКИ ПОПУЛЯЦІЇ КАРАСЯ СРІБЛЯСТОГО (CARASSIUS GIBELIO B.) КРЕМЕНЧУЦЬКОГО ВОДОСХОВИЩА

Ukraine ranks first in Europe the number of natural water bodies. These abundant resources are source significant fish resources, which effectively exploited by fishing industry. Rationalization and equal distribution commercial load, reduction pressure on main species has always been an urgent issue. This can be achieved shifting focus to other types fish, will allow rational use entire complex species. The Prussian carp Carassius gibelio (Bloch, 1782) is among such promising objects - a massive, small-particle species, certain bodies displaced minor formed stable numerical populations. 
 A decisive role age structure formation population was played increase specific middle older groups, associated with insufficient level load. Thus, variation series this catches 2021, unlike had form double-peaked curve, due loss size classes 25-28 cm. According Fishing Rules Regime Fishery Operation Dnipro Reservoirs force today, nets step allowed hole a=38-49 mm 70 more. load selectivity reduces bream However, it also causes stock carp. And alien populations Kremenchuk Reservoir. its average annual catch period 2000-2020 increased from 44.6 462.4 tons or 10 times 20 years. We should note that occupied insignificant segment no more than 0.1% weight traditional set gill (a=75-90 mm) at Reservoir, while, 50-60 mesh dominant share up 60% weight. indicators characterize fisheries environmental protection components net deals part target objects, indices, bycatch immature commercially valuable generally meet requirements for current legislation might used targeted harvest littoral zones. Considering need intensify high actual mass mm, implementation specialized Dnieper reservoirs considered as means optimizing bioresource fishery. In order minimize negative impact structural functional population, focused areas accumulation carp, i.e. fishery least 50%. necessity meliorative capture introduction aimed downgrade reproductive core prevent uncontrolled growth.
