摘  要:
本文报告了作者近二年在长江流域池塘养殖和大水面养殖辽蟹的情况,并进行了较大范围的养殖效果调查。结果表明,与长江蟹相比辽蟹的养成规格、回捕率、群体增重倍数均明显低于长江蟹,性腺成熟也较长江蟹早。但如技术措施得当,仍能取得较好的经济效益。

摘  要:
The author reports the pond-culture and big-water-area-culture in Yangtze River Basin of Eriocheir sinensis from Liao River System in the past two years. An investigation on a large scale of cultivation efficiency is also implemented. The re-sults show that the marketable size,catch rate and multiple of increase in population weight of crab from Liao River System is remarkably lower than that from Yangtze River System. The maturing of sexual gland in crab from Liao River System is earli-er than that from Yangtze River System. But, supposing appropriate technical mea-sures are taken, satisfactory profits would still be obtained.
