Abstract：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.
