赛里木湖饵料生物及渔业现状的研究

Research of Fishery sttuation and Feed creature of Sailimu lake

赛里木湖为高山冷水型封闭湖 ,面积 453Km2 ,年平均水温 7℃。 1 997年 :透明度 1 3m ,离子总量 2 967mg/l,水化学型为SMgⅡ ;浮游植物平均 0 436mg/l,以硅藻和蓝藻为主 ;浮游动物平均为 0 32 2 5mg/l,以西藏拟蚤和镖水蚤为主 ;初级生产力为 2 65Kg鱼 /亩·年。自 1 968年引入新疆土著鱼类以来 ,至今未形成商业产量。 1 996年试引虹鳟 ,生长速度较佳。为开发该湖丰富的冷水资源 ,建议移植冷水性浮游生物食性的鱼类 ,改变引种结构 。

The Sailimo lake is a cold water lake at the plateau and covers an area of 453Km 2 The average water temperature is about 7℃ at every year.In 1997,the clarity was 13m.Totalion amountion was 2967mg/l.The main of water chemistry ingredient was sulphuric acid Mg.The phytoplanktons’s amount of biomass varies between 0 156mg/l and 0 536mg/l with an average of 0 436mg/l.The zooplantons’s amount of biomass was 0 3225mg/l.The primary productivity was 2 65kg per acreage year in the lake.Since 1968,the lake to has transplant aboriginal fish of Xinjing.It still,doesn’t shape commerce output.In 1996,we tried to transplant Salmo gairdnerii Richardson into the lake,That growing fine.For the development cold water natural resources,we suggest to transplant some fish that ingest plankton in the lake.The purpose is to change the structure of fishery and to achieve commerce development.
