摘  要:
水丰水库的渔获量 196 1- 1980年间变化于 4 7~ 30 0t,1981~ 1984年增长到 74 0~ 132 1t,1985~ 2 0 0 0年为 2 2 70~ 4 92 6t。渔获物组成中以亚洲公鱼为主 ,1980~ 2 0 0 0年亚洲蚣鱼占总渔获的 2 9 6 %~ 93 0 % ,平均为 6 5 6 %。鲤鲫鱼占 6 2 %~ 16 4 % ,鲢鳙鱼占 8 1%~ 13 3% ,鳊鲂占 1 8%~ 11 3% ,虾占 5 9%~ 16 1% ,其它鱼类占 2 4 %~ 9 3%。 2 0 0 0年大银鱼占总渔获的 2 8%。 1985~ 2 0 0 0年水库鱼类资源相对稳定。亚洲公鱼、青虾和大银鱼三种小型经济鱼虾的种间关系表现为互利共生 ,竞争和残敌关系 ,可能向种间形成平衡调节方向发展

摘  要:
The annual capture yield changed from 47t to 300t during 1961~1980 and it was from 740t to 1312t in 1981~1984.Then it increased 2270~4926t in 1985~2000.The composition of capture yield in 1980~2000 asian smelt constituted a mainly part and auounted for 65 6% of the total,next came 6 2%~16 4% are common carp and crucian carp,8 1%~13 3% are silver carp and bighead,1 8%~11 3% are white bream and black bream,5 9%~16 1% are shrimps and 4 3%~9 3% are silver carp and bighead,1 8%~11 3% are white bream and black bream,5 9%~16 1% are shrimps and 4 3%~9 3% are the other fishes.The large icefish occupy 2 8% of the total capture yield in 2000.The fishery resource was kept relatively stable during 1985~2000. The interspecific relationship of 3 species (asian smelt,large icefish and shrimps) showed that as fallow:1 mutualism,2 competition,3 adversary,and it can be developed to direction of interspecific balance regulation.
