摘    要:采用室内流水模拟法测定了摄食水平与铒料生物种类对真鲷、黑鲷、黑Jue特定生长率和生长效率的影响。3种实验鱼类的物壹生长率均随摄食水平增大呈减速增长趋势。二者间的定量关系和对数曲线描述;而其生长效率则均随摄食水平增大呈倒“U”形变化趋势。二者间的定量关系可用二次曲线描述,曲线相关检验结果表明,其特定生长率和生长效率与摄食水平之间均呈显著相关关系。依据上述定量关系,分别求得3种鱼的维持摄食量和最佳摄食

关 键 词:真鲷 黑鲷 黑Jue 特定生长率 铒料种类

Abstract:Using flowing - water simulating experiment in laboratory, the experiment was conducted with 3 species of fishes which were Pagrosomus major, Sparus macrocephalus and Sebastodes Sebastodes. The results show that their specific growth rates (SGR) increase with the rise of temperature or ration (FL), and the quantitive relationship between them can be described as SGR = m' InFL - n; the ecological conversion efficiency (Eg) decreases gradually after increasing to a peak value with the rise of temperature or ration, and their quantitive relationship can be described as Eg =- a' FL~2 b' FL c. According to the formula above, the maintenance rations and optimum ration can be calculated that the maintenance ration of S. fuscescens was the lowest among the 3 fishes. Different feed can affect their growth that when using Ammodytes personatus as feed the SGR of the 3 fishes are higher than using Trachypenaeus curvirostris. But the Eg has no significant difference between the 3 when using energy value (kJ'g~1 ) as calculated basis.
Keywords:Pagrosomus major  Sporus macrocephalus  Sebastodes fuscescens  specific growth rate  growth efficiency  ration  food species
