柴河水库捕捞池沼公鱼的各种渔具、渔法

柴河水库于1987年和1989年引进池沼公鱼受精卵共5400万粒。1996年后池沼公鱼数量大增,形成了良好的自然种群。调查池沼公鱼在柴河水库的栖息规律,找到适合池沼公鱼捕捞的渔具渔法,对综合利用池沼公鱼资源、提高经济效益具有现实意义,同时通过合理捕捞,既可以发挥池沼公鱼渔业效益、控制池沼公鱼数量,又可以为水库主体鱼花、白鲢提高生存空间、节约饵料生物。

Fishing Gears and Methods for Pond Smelt in Chaihe Reservoir

A wild population of pond smelt(Hypomesus olidus)was increased after 1996 since 54 millions of the fertilized eggs successively introduced into Chaihe Reservoir,Liaoning province,China,in 1987 and 1989. The effective fishing gears and fishing methods for the pond smelt were created via the habitation pattern of the pond smelt in Chaihe Reservoir to comprehensive utilization of the pond smelt resources. Meanwhile,the reasonable fishing can not only give scope to the fishery benefit of the pond smelt,but also improve the life space and natural food available for the principal fishes including bighead carp(Aristchthys nobilis),and silver carp(Hypophthamichthys molitrix)in the reservoir.
