The necessity of conducting research on the impact sources pollution Dnipro River depending their is determined.It has been established that basin a multi-sectoral complex covers 48% territory Ukraine and accumulates 80% water resources.It noted high natural socio-economic value, as it meets drinking needs 70% population Ukraine.It are industrial complexes, agriculture, urban agglomerations.It proved deforestation, intensification hydromelioration, functioning reservoirs cascade, intensive use resources causes destruction.It determined agricultural development catchment areas caused soil erosion, which most important mechanism substance migration earth's surface, causing up to 17 billion tons mineral particles 3.5 dissolved substances enter seas, oceans internal runoff zones annually.It concentrations in surface reduce quality, requires additional costs for treatment, repair supply network, restoration irrigation networks.The article calculated zonal hazard nutrient waters within multi-level sub-basins transboundary River, consequence soil-erosion processes.It located mixed forest zone or upper part river have lowest potential diffuse by suspended solids.It order assess degree danger bodies with phosphorus, necessary establish "ecologically limiting" values actual concentration.It Lower steppe zone, potentially dangerous accordance indicators phosphorus concentration waters.The developing adaptive landscape erosion control projects elements protection agriculture determined.

Aquatic biological resources and their effective using form the basis of sustainable development fish farming aquaculture in each country.It is an important resource food security, which will determine its state near future, taking into account latest global trends.In recent years, trend towards a decrease catching aquatic resources, producing own products, level consumption products per capita with simultaneous increase import dependence market, indicates absence system insufficient financial support for fishing industry, has been observed Ukraine.But, namely fisheries, as complete complex, plays very role economy Ukraine.The purpose work was to find out current extracting bioresources analyze by Ukrainians.The dynamics general internal water bodies, value indicators development, funds Ukrainians 2021 were analyzed on specialized literature, regulatory legal documents related and, particular, farming, statistical data scientific works scientists dedicated industry structures sea freshwater catch volumes main species studied, changes that occurred cost structure caught analyzed.According consuming staple foods population Ukraine 2021, it established last place.It due low purchasing power rising prices falling incomes most Ukrainians.As result conducted research, regulation insufficiently creates additional barriers business entities, leads unequal access common limited irrational bodies bioresources.
