Planting yearlings is a key stage in the fish rearing cycle, determining the future productivity of the water body and the efficiency of feed resource utilization. For an agronomist and a pond farm owner, proper organization of this process allows for the transition from extensive fish farming to intensive production levels. Competent management of stocking density, proper selection of species composition in polyculture, and a well-tuned feeding system are the guarantee of high survival rates and rapid weight gain in cyprinids.
This selection contains practical recommendations for optimizing work with fish stocking material. Readers will find methods for increasing fish productivity through the use of mixed stocking and natural biogenic resources, as well as detailed instructions on rationing compound feed while taking into account the hydrochemical indicators of the water. In addition, the materials cover the technological aspects of working with roe: from assessing the quality of sexual products to the processes of artificial fertilization and degumming, which is necessary to provide the farm with its own high-quality fish stocking material.
