彭泽鲫种质特性与品种改良研究进展及展望

Research progress and prospects on the genetic characteristics and breeding of Pengze crucian carp

摘要:

彭泽鲫具天然雌核发育的生殖特性，同时具有生长快、个体大、适应性强等优良性状，是我国重要的淡水经济鱼类。彭泽鲫进行遗传改良后培育出的两个养殖新品种—白金丰产鲫和穗丰鲫，目前取得显著经济效益，养殖范围涉及全国多个省市。本文综述了国内三十余年来关于彭泽鲫的研究进展，包括生物学特性、分类地位、养殖技术、与不同品种的杂交结果等；对白金丰产鲫和穗丰鲫的选育工作进行了总结，包括其亲本选择、培育过程和改良后的优势等；并对彭泽鲫种质资源研究存在的问题和未来方向进行了探讨，为后续彭泽鲫相关研究提供参考。

Abstract:

The Pengze crucian carp (Carassius auratus var. pengsenensis) is a subspecies of the crucian carp characterized by natural gynogenesis, rapid growth, large body size, and high adaptability. These traits render it a valuable and economically important aquatic species in China. In recent years, two notable varieties of Pengze crucian carp, the Platinum fertility crucian carp and the Suifeng crucian carp, have generated significant economic benefits. This review summarized research progress on Pengze crucian carp over the past four decades, covering its biological characteristics, breeding technology, and hybridization with other fish species. Additionally, we highlighted efforts to develop the Platinum fertility crucian carp and Suifeng crucian carp. Finally, we discussed key challenges and unresolved issues that must be addressed in the near future and propose potential directions for future research on Pengze crucian carp in aquaculture.
