按照《内陆水域渔业自然资源调查手册》对天嘉湖水化学、浮游生物、底栖动物、鱼类状况进行了调查。结果表明:天嘉湖水质良好,适合鱼类生长;鱼类天然饵料生物量相对较低,不适合鲢鳙生长;主要渔获物为人工放养的异育银鲫Carassiusauratusgibelio.,今后应依据其自然条件以放养异育银鲫为主,少放鲢鳙;放养12cm以上的大规格的鱼种,提高成活率和回捕率;控制凶猛鱼类的种群数量。
According to the Handbook for Investigation of Natural Resources of Inland Waters Fisheries, the status of chemical, plankton, zoobenthos and fish in Tianjia Lake was investigated. The results showed that the water quality of Tianjia Lake was good and suitable for the growth of fish. The natural fish food biomass was relatively low and unsuitable for growth of silver carp and bighead carp. The main catches were artificial Carassius auratus gibelio Conditions to stocking allogynogenetic crucian carp, put a small silver carp and bighead carp; stocking large size of more than 12cm species, improve the survival rate and capture rate; control the number of ferocious fish populations.
