水利渔业多年形成的以放养鲢、鳙为主体的生产模式对增加鱼产量起到了巨大作用。但黑龙江省一些水库常因鱼苗、鱼种、设施、劳务等的投入困难而受到限制。大银鱼移植成本低,效益高,不需每年投放鱼种,市场前景广阔。在适宜移植大银鱼的水库及时转变传统的生产模式,走以移植增殖大银鱼为主的路子,具有重要意义。
For many years, water conservancy and fisheries to produce silver carp and silver carp, as the main mode of production to increase fish production has played a huge role. However, some reservoirs in Heilongjiang Province are often restricted due to difficulties in inputting fish fry, fish species, facilities and labor services. Large silverfish transplantation cost is low, high efficiency, do not need to run fish species every year, the market prospect is broad. It is of great significance to change the traditional mode of production in a timely manner for reservoirs that are suitable for transplanting the big silverfish and to take the path of transplanting the big silverfish.
