投喂三种商品性的鲑鳟鱼类饲料、一种试验性的甲壳动物饲料、与一种活饵料(颤蚓)对照,作美洲鲟幼鱼生长和存活试验,结果证明,某些加工饲料,特别是一种半潮湿性饲料,能作为美洲鲟开始摄食时头40天的饲料。虽然投喂半潮湿性饲料时鲟鱼的生长率比喂活饵料要低,但存活率仍一样,而且可以避免过去把鱼从喂活饲料转移到喂加工饲料时所产生的高死亡率。干饲料不能被很好利用,而且幼鱼生长率和存活率都很低。
Feeding three commercially available salmon trout feeds, a tentative crustacean feed, in contrast to a live bait (trematode), as a test of juvenile juvenile growth and survival, showed that certain processed feeds , Especially a semi-moist feed that can serve as the first 40 days of feeding when the American sturgeon begins feeding. Although sturgeon growth rates are lower when fed semi-moist diets than with live bait, survival rates remain the same and avoid the high mortality rates associated with the transfer of feed from live feeds to feed processed feeds. Dry feed can not be well utilized, and juvenile growth rates and survival rates are low.
