| 本研究设置10、25、50尾/m2 3个养殖密度，人工饵料、鲜菲律宾蛤仔肉两种饵料，不喂(N)、少喂(L)、饱喂(F) 3个处理，分别于投喂前1 h、投喂时、投喂后1 h测定日本囊对虾(Marsupenaeus japonicus)的争斗次数、平均优势指数等指标，分析养殖密度、饵料种类及丰度对日本囊对虾争胜行为的影响。结果显示，随着养殖密度的增加，对虾的争胜行为逐渐增强，投喂时与投喂前、投喂后对虾的争胜行为差异显著(P<0.05)；投喂时对虾的争斗次数最多；饵料种类和丰度显著影响日本囊对虾的争胜行为，投喂菲律宾蛤仔肉的争胜行为强于投喂人工饵料(P<0.05)，少喂与不喂、饱喂处理间差异显著(P<0.05)。研究表明，养殖密度、饵料种类及丰度均显著影响日本囊对虾的争胜行为。 |
| 英文摘要: |
| Cannibalism is one characteristic of Marsupenaeus japonicas with little understanding, which affects the survival rate and the production of M. japonicas. The current study was designed to investigate the effects of the stocking density, food types and abundance on the agonistic behavior of M. japonicas. Three stocking densities (10, 25 and 50 ind/m2) and three food amounts (full food, less food, and no food) were designed. Agonistic behavior were observed and recorded one hour before feeding, during feeding and 1 hour after feeding. The results showed that the agonistic behavior increased with the increasing stocking density. There were significant differences between “before feeding”, “during feeding” and “after feeding” (P<0.05). Feeding time significantly improved the agonistic behavior. Food types and abundance significantly affected the agonistic behavior(P<0.05). Clam meat had better improvement in agonistic behavior than artificial feed. The stocking density did not impact the agonistic behavior before feeding and during feeding, but it had significant effect after feeding(P<0.05). These results revealed that stocking density, food type and abundance could impact the agonistic behavior of M. japonicus. |
