【摘要】 经测量和数理统计分析,确定池养条件下幼螯（中华绒螯蟹幼蟹,下同）背甲长与年龄呈直线关系,体重与年龄为幂函数关系,并计算出它们相应的回归方程式。研究结果表明,在不同饲养条件下,幼蟹生长率略有差异,并揭示出幼蟹个体生长存在着显著的差异性。在营养和溶氧相似的条件下,动蟹在适温范围内的生长与水温呈正相关。根据对185只不同时期幼蟹的测量,计算出幼蟹背甲长对体重的关系式为W=0.4209L^3.1150。更多还原

【Abstract】 The present paper deals with the growth characteristics of the juve-nile of woolly handed crab （Eriocheir sinensis） cultivated in ponds. The relationshipof length （L）/age （T） falls on a straight line, but that of weight （W）/age （T） isexponential. The regression equation of length or weight and age was determinedthrough calculation. The results obtained showed that there is a little differenceabout growth rate of the juvenile crab under different culture conditions, but obvi-ously there is a significant difference in individual growth. Either indoor or outdoorunder same food ration and dissolved oxygen, the relationship of the juvenile crabgrowth with water temperature is a positive correlation between 16.5℃ and 32.0℃.The general equation of the juvenile crab, based on the measurement of 185 indivi-duals, can be expressed as W=0.4209L^3.1156.更多还原
