INFLUENCE OF FERTILIZERS ON THE DEVELOPMENT OF ZOOPLANKTON

In the article, that the introduction of nitrogen-phosphorus fertilizer stimulates the development of zooplankton in the rearing ponds. Established as influences the development of zooplankton of the ponds making them optimal doses of nitrogen-phosphorus fertilizers. For experiments were used four ponds in the fish farm "Sarsky", located in the V ecological and phenological fish zone. The application of mineral fertilizers had a positive effect on primary production. Photosynthesis in fertilized ponds were more intensely, improving trophic conditions of zooplankters. Using zoologicheskogo analysis revealed one typical pond complex – Basmanny. In fertilised ponds dominant species was higher (3-4) and higher was the overall significance (219-574) compared with the control (respectively 2 and 132). The dominant thought of the view from a measure of the value not below 20. Species composition of zooplankton in fertilized and control ponds, were mainly the same, the significant differences observed in quantitative terms.
