洱海是云南省主要的水产基地之一。于2009年8月和11月,对洱海进行了鱼类资源调查,渔获物中有鱼类23种,隶属于6目9科,其中,子陵栉鰕虎鱼(Ctenogobius giurinus)、波氏栉鰕虎鱼(Ctenogobius cliffordpopei)、麦穗鱼(Pseudorasbora parva)等小型低值品鱼类在种类和数量上占据优势;鲫(Carassius auratus)、鲤(Cyprinus car? pio)等原定居型经济鱼类产量不高;太湖新银鱼(Neosalanx taihuensis)以及依赖于人工放养的鲢(Hypophthalmich? thys molitrix)、鳙(Aristichthys nobilis)等经济鱼类成为渔业主体。参照国家《渔业水质标准》(GB11607—89)以及 《地面水环境质量标准》(GB3838—88),对2004～2009年洱海的水质监测数据,包括透明度、pH、高锰酸盐指数、五日生化需氧量、氨氮、总氮、总磷等指标,进行了分析。研究结果表明,洱海水质整体上为Ⅲ类水质,处于中营养化水平,除透明度、pH两项指标存在超标现象以外,其他指标总体处于正常渔业水质标准范围之内。针对当前洱海的渔业资源和水环境现状,提出了“增殖现有放养经济鱼种—控制小型低值品鱼种—恢复原有珍稀土著鱼种”和“增殖现有放养经济鱼种—引进优良新品种”两种具有不同侧重点的渔业发展模式。 |

This essay had investigated the fish resources at 21 sites in the Erhai Lake in August and November 2009.The nets were put into water in every sampling site of the lake at around 5 pm and pulled them back at 5 am the next day.The sampling was conducted for 3 times in each site,and the species and amounts of fishes, sampling time,latitude and longitude of sampling sites,types of nets and other information were recorded. The fishes were identified and classified by referencing to‘The Fishes of Yunnan’.The results showed that there were 23 species,belonging to 6 orders and 9 families.The most abundant family was Cyprinidae which contained 14 species and accounted for 60.9%of total number of species.And the fish fauna of Erhai Lake was similar to that of the lower-middle reaches of the Yangtze River.The population of Ctenogobius giurinus and Ctenogobius cliffordpopei was larger,accounting for 96.1%of total amount;next was Neosalanx taihuensis, which accounted for 2.9%.The small-size fishes(i.e.Ctenogobius giurinus,Ctenogobius cliffordpopei and Pseu? dorasbora parva)were predominant not only in the number of species but also in the yield;the yields of original commercial Carassius auratus and Cyprinus carpio were lower;the artificial stocking fishes,such as Neo? salanx taihuensis,Hypophthalmichthys molitrix and Aristichthys nobilis,became the main species in fishery of Erhai Lake.The main fishery model in Erhai Lake was extensive farming model,and the main stocking species were Hypophthalmichthys molitrix,Aristichthys nobilis,Megalobrama amblycephala,Cyprinus carpio,and Carassius auratus.The annual fish production of Erhai Lake has continued to rise since 1999.And up to now, there was no very effective solution in control of the wild trash fishes with small size and proliferation of the rare indigenous fish species.The data of water quality from 2004 to 2009 in Erhai Lake were analyzed by the standard index.The water quality of Erhai Lake was at levelⅢ,which was in the middle level of eutrophication.The 2 developmental patterns of fishery were put with different focuses:proliferation of the stocking economic fish species,control of the small size and low value fish species,and restoration of the rare and indigenous fish species;proliferation of the stocking economic fish species,and introduction of new improved varieties. |
