摘要
本研究旨在探究脉红螺摄食喜好性,为脉红螺亲体培育选择最佳饵料为目的。实验投喂等重量的螠蛏、贻贝、文蛤、长牡蛎、毛蚶、菲律宾蛤仔、长竹蛏、青蛤、四角蛤蜊、中国蛤蜊活体饵料,计量脉红螺对各种活体贝类的摄食个数和摄食重量;然后又从脉红螺喜食的种类中选出了四角蛤蜊、中国蛤蜊、缢蛏、贻贝进行了摄食效果和成活率方面进行了实验,以促进其快速发育、交配,产出优质的卵袋,从而人工育苗打下坚实基础。结果表明,脉红螺摄食螠蛏、长竹蛏、中国蛤蜊的个数和摄食重量高出其他活体饵料,尤其对螠蛏摄食个数和重量远高于其他饵料,表现出一定的摄食喜好;四种贝类单一养成实验结果是四角蛤蜊和中国蛤蜊最好,缢蛏次之,贻贝最差,但投喂期间的活率贻贝最高,缢蛏最差。
The aims of the research were to explore the best feeding and provide the most suitable bait for parental breeding of Rapana venosa. This research used several baits include Siliqua Minima, Perna viridis , Meretrix lyrata , Crassostrea gigas , Scapharca subcrenata , Ruditapes philippinarum , Solen gouldi , Cyclina sinensis , Mactra veneri formis , Mactra chinensis with the same quantity then calculated the number and the weight of feeding in each vital bait. In order to promote rapid initial growth, mating and breed egg sac in high quality, the experiment on feeding effects and survival rate was using Mactra veneri formis , Mactra chinensis , Siliqua Minima, Perna viridis that selected from different kinds of bait. Therefore, it could lay a solid foundation on artificial breeding. The experiment showed that the feeding number and weight of Siliqua Minima, Solen gouldi, Mactra chinensis are higher than other, and Siliqua Minima is the best bait for Rapana venosa. In the experiment of paren- tal breeding, the result demonstrated that Mactra veneriformis, Mactra chinensis were the best then followed by Perna viridis, and the worst is Siliqua Minima with a lowest survival rate.
