摘    要:根据1992年12月至1993年9月的调查,丹江口水库的饵料生物资源量为1.845×10~6t.其产鱼潜力为1.615×10~4t.是现有鱼产量(包括捕捞产量和不投饵网箱产量)的5倍左右.就水体营养状态而言,汉江库区为中营养型,丹江库区属贫一中营养型.文中还对丹江口水库的渔业发展和水质保护进行了讨论.

关 键 词:饵料  生物资源  营养状态  丹江口水库  水体  鱼类

Abstract:A survey of food organism is made in Danjiangkou Reservoir which consists of Danjiang Reservoir Region and Hanjiang Rcservir Region during December 1992 and September 1993. The results show that the production of phytoplankton, zooplankton and benthos was 1.5×106 t, 3.0×105 t and 4.48×104 t respectively, a total of 1.845×106 t; the potential fishery production reached 1×104 t, 0.6×104 t and 0.015×104 t seperately, amounting up to 1.615×104 t. Based on the standing crops of phytoplankton and bio-nutrients, the trophic type of Danjiang Reservoir region could be regarded as oligmesotrophic and that of Hanjiang Reservior region to mesotrophic. The fishery development and water quality protection in Danjiangkou Reservoir were also discussed.
Keywords:Food organism resources  trophic state  Danjiangkou Reservoir
