Abstract
Purpose. To study the fisheries and biological indicators of young-of-the-year carp when applying fertilizer in ponds, introducing stock cultures of Daphnia magna (Straus) and feeding of young-of-the-year with cultured zooplankton organisms and to evaluate the effectiveness of measures for enhancing the provision of young-of-the-year carp with natural feeds. Methodology. Stock culture of Daphnia magna was added into experimental ponds, 65 kg/ha of zooplankton, which were cultured in a pond-cultivator and cages installed in experimental ponds were used for feeding young-of-the-years in July and August. For study of nutrition and growth of young-of-the-year ca...
