中华绒螯蟹血淋巴和肝胰腺的总蛋白含量与性早熟的关系

中华绒螯蟹扣蟹性腺发育与肝胰腺和血淋巴的蛋白质浓度相关.性早熟前后,雌雄扣蟹肝胰腺总蛋白浓度分别由(121.17±44.50)mg@g-1和(89.43±21.86)mg@g-1下降至(81.08±5.84)mg@g-1和(70.58±9.90)mg@g-1,雌性扣蟹的肝胰腺占体重的比值也由8.18%降至3.90%.血淋巴总蛋白浓度正常发育的雌性扣蟹为(99.55±12.06)mg@mL-1,明显高于性早熟雌性扣蟹的(72.26±17.87)mg@mL-1;而雄性扣蟹性早熟前后的血淋巴总蛋白浓度无显著差异.肝胰腺总蛋白浓度二秋龄雌蟹高于性早熟雌性扣蟹,但它们之间的血淋巴总蛋白浓度没有显著差异.二秋龄雄蟹的血淋巴和肝胰腺总蛋白浓度与性早熟雄性扣蟹相当,差异不显著.

The relationship of the total protein levels in the hemolymph and hepatopancreas with precociousness of Eriocheir sinensis

In Chinese mitten crab ( Eriocheir sinensis ) , the gonadal development of juvenile crab correlates with the total protein level in the hepatopancreas and hemolymph. The total protein level in the hepatopancreas of the juvenile crab is ( 121. 17 ? 44. 50) mg#g- 1 for female and ( 89. 43 ? 21. 86) mg#g- 1 for male respectively. But the protein level in the hepatopancreas of the precocious crab drops to ( 81. 08 ? 5. 84) mg#g - 1 for female and 70. 58 ? 9. 90mg#g- 1 for male respectively. Simultaneously, the rate between hepatopancreas and body weight of female juvenile crab is descending f rom 8. 18% to 3. 90% . The hemolymph total protein level of the female juvenile crab is ( 99. 55 ? 12. 06) mg#mL- 1, it is higher than that of the female precocious crab. The hemolymph total protein level of the male juvenile crab is similar to that of the male precocious crab. The total protein level in the hepatopancreas of the female adult crab is higher than that of the female precocious crab, but they have a approximate value of the total protein level in the hemolymph. The total protein level in the hemolymph and hepatopancreas is not different from the male adult crab and the male precocious crab.
