史氏鲟(Aclpenser Schrenckii)为肉食性鱼类,其消化系统中,既有硬骨鱼类的幽门盲囊,又有软骨鱼类的瓣肠,因此具有很高的水化吸收功能。幼鱼的食物以底栖生物、水蚯蚓和水生昆虫为主;成鱼则以水生昆虫、底栖生物和小型鱼类为食。在饲养情况下,经过驯化,可摄食人工配合饲料。 因此我们进行了人工颗粒饲料驯养史氏鲟的试验。本次试验参 Aclpenser Schrenckii is a carnivorous fish whose digestive system contains both the pyloric sac of the bony fish and the valve intestine of the cartilaginous fish and therefore has a high hydration and absorption function. Juvenile food is benthic, water earthworms and aquatic insects; adult fish and aquatic insects, benthic organisms and small fish for food. In keeping the case, after domesticated, can feed artificial feed. Therefore, we conducted artificial pelleted domesticated Acipenser schrenckii test. The test parameters
