    摘要:

    为系统评估不同来源中华绒螯蟹(Eriocheir sinensis)早熟品种(品系)在成蟹养殖阶段的表现,以申江1号、光合1号、未选育辽蟹和“北繁南养”品系为对象开展养殖实验,并对平均体质量、生殖蜕壳、组织系数、成活率及产量等关键指标进行对比分析。实验结果表明:(1)就生长性能而言,申江1号雌、雄个体在成蟹养殖中后期(7月和9月)的平均体质量均显著高于未选育辽蟹(P<0.05),光合1号和“北繁南养”品系平均体质量居于两者之间。(2)生殖蜕壳和性腺发育方面,未选育辽蟹雌、雄个体在各采样时间点的生殖蜕壳比例和性腺指数(Gonadosomatic index,GSI)均为最高,其中8月10日和8月25日时未选育辽蟹生殖蜕壳比例显著高于申江1号和光合1号个体,10月28日时未选育辽蟹GSI显著高于光合1号个体(P<0.05)。(3)养殖效果方面,未选育辽蟹雄体成活率显著低于申江1号和“北繁南养”品系,且未选育辽蟹雄体单产显著较低(P<0.05)。综上,申江1号在体质量、大规格成蟹所占比例及最终产量方面均优于另外3组成蟹,但其生殖蜕壳比例及性腺发育速度略低于未选育辽蟹,故不同地区在成蟹养殖中可根据实际生产需求选用合适的中华绒螯蟹早熟品种(品系)。

    Abstract:

    To systematically evaluate the culture performance of different early-maturing strains of Chinese mitten crab (Eriocheir sinensis) during the adult stage, culture experiments were conducted with four strains: Shenjiang No. 1 (SJ), Guanghe No. 1 (GH), unselected Liao strain (ULS) ,and Northern-breed strain(NBS). Key indicators such as average body weight, puberty molting, organ coefficients, survival rate and yield were compared. The results revealed that: (1) The average body weight of SJ individuals (both female and male) in the mid-to-late adult rearing stage (July and September) was significantly higher than that of ULS (P<0.05), with GH and NBS ranking between them. (2) The puberty molting rate and gonadosomatic index(GSI) of ULS (both female and male) were the highest at all sampling points. On August 10 and August 25, the puberty molting rate of ULS was significantly higher than that of SJ and GH (P<0.05), while on October 28, their GSI was significantly higher than that of GH (P<0.05). (3) The survival rate of ULS was significantly lower than that of SJ and NBS, and the male and overall yield of ULS was significantly lower than that of the other strains (P<0.05). In conclusion, SJ outperformed the other strains in average body weight, the proportion of large-size adult crabs, and final yield. However, its puberty molting rate and gonadal development speed were slightly lower than those of ULS. Thus, the selection of suitable early-maturing varieties (strains) of E. sinensis for adult culture in different region should be based on specific production requirements.
