    摘要:

    为探讨饲料中添加南极磷虾粉对中华绒螯蟹(Eriocheir sinensis)亲蟹的营养强化作用, 通过 60 d 的饲养实验, 评估了南极磷虾粉对中华绒螯蟹繁殖性能及胚胎质量的影响, 分别在饲料中添加 0%、10%和 20%南极磷虾粉作为 3 个实验组, 并以投喂缢蛏作为对照组, 每组设 3 个平行。分析各组雌蟹肝胰腺重量(HW)、性腺重量(GW)、肝胰腺指数(HSI)和性腺指数(GSI)的变化特征。营养强化结束后开展了亲蟹的繁殖实验研究, 每组设 3 个重复, 每缸中放 5 只雄蟹和 10 只雌蟹, 比较各组中雌蟹的产卵量、生殖力和生殖指数等繁殖性能, 分析胚胎卵径、重量、生化成分及脂肪酸组成。结果表明: (1) 营养强化后, 各饵料组中雌蟹的肝胰腺重量和肝胰腺指数均显著低于强化前 (P＜0.05), 性腺重量和性腺指数均显著高于强化前(P＜0.05), 其中以 20%组最高。(2) 雌蟹的产卵量和生殖力均以 20%组中最高, 但各组间生殖指数无显著差异(P＞0.05)。(3) 各实验组胚胎卵径、卵重、水分、粗蛋白、总蛋白和粗脂肪均不存在显著差异, 20%组中磷脂(PL)含量最高, 且与其他各组均有显著差异(P＜0.05); 10%组中甘油三酯(TG) 含量最高, 平均为(1449.73±101.38) μg/g, 且显著高于其他各组(P＜0.05)。0%组和对照组胚胎中胆固醇含量(CHOL) 均显著高于 10%组和 20%组(P＜0.05)。(4) 0%组中 C20∶2 和 C20∶4n6 含量最高, 且显著高于 10%组(P＜0.05), 但 SFA、MUFA 和 PUFA 各组间均无显著差异(P＞0.05)。结果表明, 饲料中添加 10%~20%南极磷虾粉能促进中华绒螯蟹雌蟹的性腺发育, 其中 20%南极磷虾粉能显著提高繁殖性能和改善胚胎质量。

    Abstract:

    To explore the nutrient enrichment effect of Antarctic krill meal to Eriocheir sinensis brood stocks, a 60-d feeding trial was conducted on the reproductive performance and embryo quality of the Chinese mitten crab, Eriocheir sinensis. Three diets were formulated, incorporating varying levels of Antarctic krill meal at 0%, 10% and 20%, with a control group fed razor clam Sinonovacula constricta. The hepatopancreatic weight (HW), hepatopancreas index (HSI), gonadal weight (GW), and gonadosomatic index (GSI) were detected after 60 d of nutritional enrichment. Each treatment had three replicate tanks stocked with five males and 10 females. The reproductive performance of broodstock and embryo quality—such as egg production, fecundity, reproductive index, egg diameter, weight, and biochemical and fatty acid compositions—were analyzed. The results showed: (1) The HW and HSI of female crabs in each group significantly decreased (P＜0.05), while GW and GSI increased significantly (P＜0.05) after 60 d, with the 20% group showing the highest values. (2) Egg production and fecundity of female crabs reached their peak in the 20% group, with no significant differences (P＞0.05) in reproductive indices among all groups. (3) The phospholipid content in the 20% group was significantly higher than that in the other groups (P＜0.05), the highest triglyceride (TG) content was found in the 10% group, with an average of (1449.73±101.38) μg/g, significantly higher than other groups (P＜0.05), cholesterol content in the 0% and control groups were significantly higher than that in the 10% and 20% groups (P＜0.05). No significant differences were observed in egg diameter, egg weight, moisture, crude protein, and crude fat between the groups (P＞0.05). (4) The content of C20 : 2 and C20 : 4n6 was highest in the 0% group, with a significant difference compared to the 10% group (P＜0.05). However, no significant differences were found in the total content of saturated fatty acids (SFA), mono-unsaturated fatty acids (MUFA) and poly unsaturated fatty acids (PUFA) among all groups (P＞0.05). The results indicate that 10%~20% and 20% dietary Antarctic krill meal could promote gonadal development of the female E. sinensis and significantly improve reproductive performance and embryo quality, respectively.
