虹鳟对不同盐度水的适应,使其在盐水及海水水域的商品鱼养殖成为可能。 1977年开始网箱养殖虹鳟,盐度10—30‰。在生产规模获得虹鳟幼鱼以前,必须自己养殖亲鱼,然后才能说明能否进行卵的人工孵化及用井水及取土坑的水培育幼鱼。亲鱼一冬龄,平均重50克,1977年由明斯克省《沃尔马》养鱼场运来,然后由平均重5—10克当年鱼补充后备亲鱼,同年由《沃尔马》及《班加》立陶碗共和国养鱼场
The adaptability of rainbow trout to different salinity water makes it possible to breed commercial fish in salt water and seawater. Rainbow trout cultured in cage since 1977, salinity 10-30 ‰. Prior to obtaining juvenile rainbow trout on a production scale, broodstock must be raised before they can be hatched for their eggs and young fish are fostered with well water and borrow pit water. The broodstock, a winter-age, weighs an average of 50 grams. It was brought in by the “Wal-Mart” fish farm in Minsk in 1977 and was supplemented by an average of 5 to 10 grams of fish in the same year. In the same year, “Volma” and “ Banjar ”Lithuania fish farm
