Research about the Influence of Environmental Factors on Breeders Quality

Abstract

Along the growth period of the breeders, the monitoring of environmental parameters is a fundamental condition to ensure the quality of the breeders used for reproduction. The results from the research presented in this paper were obtained following experimental type investigations developed in vegetation and cold season within Carja 1-Vaslui fish farm, on chemical and biological samples which were analyzed within the research laboratory of the Department of Aquaculture, Environmental Science and Cadastre. Were analyzed parameters which influence bio-productivity: temperature, oxygen, pH, the concentration of nitrites, nitrates, phosphates, the density and abundance of phytoplankton and zooplankton, the individual weight and health condition of breeders. Analyzed parameters included mean values recorded in the optimal range for fish waters, as reflected in the numerical density and abundance of plankton and the average weight of Asian cyprinids breeders with a plankton nutritional spectrum.
