摘要
本文报道池养长毛对虾体长在6．8～123．9mm范围内的体长与体重的关系。池养长毛对虾雌、雄群体的生长特点是雌虾快于雄虾。由雌雄混合、雌虾、雄虾群体的体重对体长的相关曲线都很接近。在比较池养与海捕长毛对虾体重与体长的回归方程时发现彼此无显著性差异。本文推荐雌雄混合群体的体重对体长的回归方程式W＝3．018×10－6L3.3213作为体长换算体重用于投饵率和估计产量的计算式。
This artical reports the relationship between body weight and length of pond-culturedPenaeus penicillatus whose body length is between 6. 8mm to 123. 9mm. When the bodylength of the prawn is longer than 34mm, its sex can be identified. The male and femalegroup show distinct growth difference in their body length and weight with female groupgreater than the male. In the study, we found that the regressive equation between the bodyweight and length of female and male mixed group was W=3. 018 × 10-6 L3.321l3, the regresslve equation of the female group W = 6. 642 × 10-6L3. 1448,and the male group W = 6. 316 ×10-6L3.1543, Finally, the equation o0f the mixed group was compared with the natural prawn,and the results showed that there was no eviden deference in that relation for body lengthfrom 34mm to 124mm, between the pond-oultured and the natural prawns and the same results to the female group and the male group. Therefore, the regressive equation of themixed group is recommanded to used in calculating the feeding rate and the products.
