菲律宾蛤仔,太平洋牡蛎和欧洲牡蛎在1000L再循环海水上升流系统中养殖.菲律宾蛤仔用混合干藻(扁藻Tefraselmis suecica和小环藻Cyclotella cryptica)投喂的生长速度略低于用鲜混合藻类(扁藻和骨条藻Skeletonema costatum).投喂90%干扁藻和10%鲜骨条藻混合饵料和投喂鲜藻混合饵料一样好.使用含有小环藻干饵料的鲜骨条藻混合饵料时,未能促进其生长.投喂100%干饵料生长在上升流循环系统的菲律宾蛤仔稚贝,转移到海里表明比投喂100%鲜饵料有更大的生长潜力.太平洋牡蛎和欧洲牡蛎,使用含30%~50%鲜骨条藻同干藻类的混合饵料,维持其生长和鲜混合饵料一样好.本文还讨论了在室内育苗场有关双壳贝类的投饵量和成本问题.
Ruditapes philippinarum, Pacific oyster and European oyster were raised in a 1000 L recirculating seawater upflow system. Ruditapes philippinarum fed with mixed dry algae (Tefraselmis suecica and Cyclotella cryptica) grew slightly slower than fresh-mixed Algae (Tetrapod and Skeletonema costatum). It was as good as feeding 90% dried algae and 10% fresh algae mixed feed and feeding algae mixed bait. When mixed bait, it failed to promote its growth.Adding 100% dry bait grew in the upwelling circulatory system of the juvenile clams in the clam and transferred to the sea, indicating that there is a greater growth potential than feeding 100% fresh bait.Pacific oyster and European oysters use as much as 30% to 50% of the mixed feed of Skeletonema algae and dried algae to maintain their growth as well as freshly mixed bait.The article also discusses feeding and costs of bivalve molluscs in indoor nurseries problem.
