中文摘要：

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。

英文摘要：

The new variety of ayu （Plecoglossus altivlis） named ＂Zhemin No.l＂ was selectively bred from wild fish population which was captured in Fuxi stream, Ninghai, Zhejiang province in 2002. A population selection process was performed by using growth traits and shape as the main selection index. After successive sevengeneration of mass selection, a novel breeding line of ayu termed ＂Zhemin No. 1＂ was successfully established. Compared with common ayu cultured under the same conditions, the body length and weight of Zhemin No.1 at 9-month old were 11.36 % and 25.92% higher, respectively. During 2012-2014, the pilotscale culture of Zhemin No. 1 reached 45 000 m2 freshwater. The survival rate of Zhemin No. 1 at 9 month old was 30.00% higher than common ayu. The deformity rate of Zhemin No. 1 at 9 month old was close to zero. The average revenue increased by 38.98%. The breeding process, germplasm characteristics, qualified traits and pilot test of Zhemin No. 1 were detailedly described in this paper. This article will be beneficial for the breeding of other aquatic species and the expanding aquaculture of Zhemin No. 1.
