滁州鲫种质资源现状与选育技术探讨

The Germplasm Resources Situation and Breeding Technology of Chuzhou Crucian Carp(Carassius auratus)

滁州鲫产于安徽省滁州市,是我国七大天然雌核发育的鲫鱼种群之一。该鱼生长速度快、个体大、耐低氧、不易染病,更因其肉质细嫩,味甘香醇,一直深受养殖户与当地居民的欢迎,具有巨大的选育和推广应用价值。本文概述了滁州鲫在形态特征、生活习性、养殖技术、养殖性能、遗传特征等方面的研究进展。同时,作者利用滁州鲫种群克隆的多样性和其具有两性生殖、雌核发育的能力,应用现代分子生物学和传统生物学相结合的方法,为滁州鲫的选育提供了新的思路和技术路线。本文丰富了滁州鲫生理生化资料,为科学化选育和饲养滁州鲫提供依据。

The Chuzhou Crucian carp （Carassius auratus） is one of the seven natural gynogenetic carp populations. It is originally founded in Chuzhou City, Anhui. The fish have many excellent characteristics： the fast growth, larger than the common carp, strong and antihypoxia, disease resistance, tender and mellow meat. So the fish have a huge application value and been welcomed by farmers and local residents. The paper summed up the research progress of the Chuzhou Crucian carp in the morphological characteristics, living habits, breeding technologies, genetic characteristics and so on. The diversity of the population and the modes of bisexuality and gynogenesis were applied to the process of breeding. In addition, the paper also provided the new ideas and technology roadmap which were integrated the modern molecular biology and traditional biology for the breeding of the Chuzhou Crucian carp. The paper enriched the physiological and biochemical informa- tion of the Chuzhou Crucian carp and provided the basis for the scientific breeding and feeding of the Chuzhou Crucian carp.
