| 摘要: |
| 根据2006-2007年太湖生物资源调查,估算出太湖浮游植物、浮游动物、底栖动物和水生植物总渔产潜力约为78494 t.太湖实施以渔改水的生物调控措施,应加大鲢、鳙放流数量和放流规格,在提高鱼产量的同时对抑制太湖蓝藻水华能起到积极作用;推算每年放流鳙约1000×104尾,鲢约300×104尾,规格为20尾/kg为宜.草鱼、团头鲂、青鱼、鲤等要在保护太湖水草和底栖动物资源和生物多样性前提下适当放流,每年宜放流草鱼150×104尾,团头鲂165×104尾,青鱼8×104~10×104尾,鲤夏花2500×104尾.而对调控鱼类结构小型化、单一化具有重要作用的肉食性鱼类翘嘴鲌建议加大放流量,年放流量可扩大至500×104尾左右,在调控的同时提高湖泊渔业附加值. |

| Abstract: |
| According to the investigations of biological resources in Lake Taihu during 2006 2007, we calculated that total fishery yield potential of phytoplankton, zooplankton, zoobenthos and aquatic macrophytes in Lake Taihu was about 78494 t. In order to increase fish yields and inhibit cyanobacteria bloom in Lake Taihu, stocking number of silver carp(Hypohthalmichthys molitrix Richardson) and bighead carp(Aristichthys nobilis Cuvier) should be increased to 10 million and 3 million tails, respectively, and the specification should be 20 tails per kilogram. To protect resources of aquatic macrophytes and zoobenthos, the reasonable stocking number of grass carp (Ctenopharyngodon idellus Cuvier), blunt snout bream (Megalobrama amblycephala Yih), black carp (Mylopharyngodon piceus Richardson) and common carp(Cyprinidae carpio Linnaeus) should be 1.5 million, 1.65 million, 80 100 thousand and 25 million tails, respectively. As topmouth cutler such as cutler alburnus could play important roles in controlling miniaturization and singleness of fishery structure and increase added-value of fishery economy, its stocking quantity should be increased to 5 million tails. |
