随着社队养鱼的发展和精养水面的扩大,各地鱼种供不应求的矛盾十分突出。一时要开挖大量鱼种池是难以办到的。利用成鱼池套养鱼种,具有省工、省饵、少占鱼池、成本低、管理容易等优点,是一条解决鱼种来源的有效途径,现已成为不少高产单位的重要增产措施。成鱼池套养鱼种,一般每亩成鱼池可提供80—150斤大规模鱼种,高的可提供300斤以上的大鱼种。如无锡市河埒公社2,312亩成鱼池共投放斤两鱼种93.44万 With the development of community fish culture and intensive water surface, the contradiction between supply of fish species in various places is very prominent. It is difficult to excavate a large number of species of fish ponds at a time. It is an effective way to solve the source of fish species by utilizing the advantages of fish farming in the fish pond, saving labor, saving the bait and taking less fish ponds, low cost and easy management. Now it has become an important stimulation measure for many high-yielding units. Into the fish pond sets of fish species, generally per acre into fish ponds can provide 80-150 pounds of large-scale species, high can provide more than 300 pounds of large species. For example, 2,312 mu of Hegang commune in Wuxi City put a total of 934,400 jin two fish species into a fish pond
