中文摘要:
      本实验采用实验生态学技术对日本沼虾摄食螺蛳的能量收支,主要环境条件(温度、盐度)对能量利用效率的影响进行了研究.建立了日本沼虾摄食螺蛳的能量收支平衡方程式.结果表明:其吸收能量,可占摄食能量的80.7%;用于生长的能量占摄食能量的34.7%,证实螺蛳向是一种热值大,又容易被虾消化吸收的天然饵料.研究还表明,水温25℃和盐度3‰时,其代谢耗能和排泄耗能最少,因而有利于提高摄食能量利用效率.本实验还测定了日本沼虾的摄食量和体重等因素对特殊动力作用(SDA)的影响,并提出生物能量学等应用基础研究是提高名、特种水产品养殖产量和经济效益的有效途径.
英文摘要:
      he effects of main environmental factors(temperature,salinity)on energy utilization efficiency and energy budget of Macrobrachium nipponensis feeding on Bellamya sp. were studied by means of experimental ecological methodoligies. An equation of energy budget of M. nipponensis feeding on Bellamya sp. was established. The results indicated that the energy used for assimilation and growth accounted for 80. 7%and 34. 7% of total energy consumption respectively. It demonstrated that Bellamya sp. meat was anexcellent natural diet for the shrimps. The meat with high energy can be easily digested and absorbed by the shrimps. The study also indicated that expenditure of metabolic and excretion energy would be minimized when water temperature is 25 `C and salinity,3%0. The paper also reported the effect of rate of feeding and body weight of M. nipponensis on its specific dynamic action (SDA)and proposed that the studies on the bioenergetics is an effective way to improve the culture yield and economic efficiency of famous and special reared species.
