The Research On Assessments For Fishery Evaluation

Fishery is a renewable resource. It is unexhausted only when properly utilized. The resistant and healthy development for fishery relies on sustainable resources of water environment. It will be helpful for preserving varieties of aquatic and prompting effectively the use of water eco-resources to study the assessments for fishery evaluation and analyze the index of fishery problem.The research on assessments for fishery development of lake gathers aspect such as the lake form characteristic, rainfall area ,submerging area, physics and chemistry properties , Biology properties , natural environment , climate meteorological phenomena and hydrology condition. The indicator system of lake fishery ecaluation divides into three build systematically for the lake form and natural environment, the lake physics and chemistry properties and the lake Biology properties appraising index system , each one build system is composed of some individual event index (or subsystem).This paper assesses Chaohu lake fishery evaluation and get the level of development fishing between 0.10 to 0.50, belongs to the low-level. Evaluation results accord with reality. Based on the evaluation results, this paper point on the main problem of the development of the fishing industry in Chaohu lake.
