方正银鲫（Carassius auratus auratus L. ）产于黑龙江省方正县双风水库，属鲫鱼的一个地理种群。它与日本和东欧银鲫一样，是一个天然雌核发育种群，因而所产生的后代与母本相似。沈俊宝等用鲤鱼精子与方正银鲫受精时没出现杂交个体，蒋一珪等用照射处理的草鱼精液受精的鲫鱼后代也与母本相似。与日本银鲫和东欧银鲫不同的是，在自然群体中方正银鲫雄鱼约占15％。由于方正银鲫较二倍体鲫鱼具有生长速度快的特点，因而它已成为我国重要的养殖鱼类。本文综述了方正银鲫研究成果，特别是对其特定遗传特性如性别决定等作了详细论述。
The genomic resources from human and several model organisms have been increased very fast since 1990. The techniques for developing genomic resources have already been very advanced and smart. These could make scientists see and improve organism in genomic level. For Chinese aquaculture scientists and aquatic industry, developing genomic resources and genetic tools for the native species are most important in the genomic era. The genomic resources and genetic tools for several aquatic species have been developed and some of them have been used in the marker based selection and other researches. The genome research work on aquaculture species was reviewed in this paper, especially a USDA genome project was focused. Some functional genomic research for aquatic animal was also discussed here. The importance and necessity of China aquaculture species genome project were discussed. Common carp and other cultured fishes in Cyprinidae such as grass carp, silver carp, bighead carp etc were recommended as the candidate species for genome research, because the output of all carps is almost up to 1/3 of total fisheries output in China. Common carp with another virtue for genome research is that there are much more families and strains in common carp than those in other cultured species in China, and those families and strains are the basis for genome research and mapping quantitative trait loci associated with important economic trait. Although the first linkage map of common carp made by Sun needs to be added with more markers for mapping QTL and Type Ⅰ markers ,it has laid the groundwork for QTL mapping and marker-assisted selection in common carp. Because the model organism zebrafish and common carp, grass carp and other carps cultured in China all belong to Cyprinidae, the China carp genome research will obtain a lot of useful information from zebrafish genome research. How the China carp genome program will be conducted and what kinds of strategy involved in this program were all suggested. How the results of the ge
