香鱼(Plecoglossus altivelis)“浙闽1号”是以2002年采捕自浙江宁海凫溪的野生香鱼为基础群体,采用群体选育技术,以生长速度和体形特征为选育指标,经7代连续选育而获得的水产新品种。该品种在相同养殖条件下,9月龄时体长生长要比当地商品苗快11.36%以上,体重生长快25.92%。2012~2014年在浙江宁海和福建南靖两处进行中试,工厂化养殖面积达4.5万m2,9月龄鱼存活率比当地商品苗提高30%以上,畸形率接近于零,平均增收38.98%。本文介绍了“浙闽1号”选育过程、品种特征和中试情况,为该品种的进一步推广养殖以及其他水产新品种的选育提供信息和资料借鉴。
Plecoglossus altivelis “Zhejiang Min 1” is a population based on wild sweetfish collected from Tiaoxi, Ninghai, Zhejiang Province in 2002. The population selection technique was adopted, the growth rate and body shape were selected as the breeding index, After 7 generations of continuous breeding of new aquatic products. Under the same culture conditions, the variety grows 11.36% faster than the local commodity at 9 months of age and grows 25.92% faster. From 2012 to 2014, pilot tests were carried out in Ninghai, Zhejiang Province and Nanjing, Fujian Province, with an industrialized aquaculture area of 45,000 m2. The annual rate of frozen-life of the nine-month-old birds was 30% or more higher than that of the same period. The deformity rate was close to zero with an average increase of 38.98 %. This paper introduced the breeding process, variety characteristics and pilot scale of “Zhejiang & Fujian No.1 ” to provide information and reference for the further popularization of this variety and breeding of other new varieties of aquatic products.
