| 1 | 葛洲坝水利枢纽工程截流后长江四大家鱼产卵场调查显示文摘本文报道了葛洲坝水利枢纽工程截流后长江四大家鱼产卵场情况。调查结果表明,长江干流上、中游四大家鱼产卵场的地理分布同60年代的调查结果基本相同。但其产卵总量仅为60年代调查结果的15.7%,资源量已严重衰减。产卵成色同60年代调查资料比较,草鱼和青鱼的比例显著增大,鳙鱼比例略有降低,而鲢鱼的比例显著下降。生殖群体结构已呈现简化(破坏),亲鱼个体变小,年龄组限减少,低龄鱼占群体数量的主导地位,初次性成熟的个体比重较大。调查表明,目前葛洲坝以上江段家鱼产卵数量占总量的36.4%,因此,在长江家鱼资源状况严重恶化的情况下,葛洲坝以上产卵场的地位就益显重要。鉴于葛洲坝水利枢纽工程阻隔了洄游生殖鱼类上溯产卵通道,葛洲坝应尽快修建过鱼设施,使草鱼等洄游性鱼类得以过坝上溯产卵,以保护或扩大四大家鱼及其他经济鱼类的资源。 | Survey Team of Spawning Grounds of Domestic Fishes in Chanjiang River | 1982 | 水产学报1982，6，4： | 74 |
