ECOLOGY AND ITS ROLE IN THE POND FISH CULTURE

Abstract

The article presents correlation materials at the fingerling and two-year carp and their growth dependence and survival, which determining fish capacity reliant on the many environmental factors. The summary literature review provides illustration about hydrochemical regime of water bodies for aquatic organism (at any trophic status). The presence of nutrients at their different levels and ratios, temperature and dissolved oxygen and carbon dioxide in water are determined the fish growth, development and survival in terms of their biological characteristics and age. The fish reactions to these factors vary depending on the stocking density, hierarchical and ethological reactions.
