| Abstract: | Flow cytometric DNA analysis of peripheral blood cells was used to determine the DNA contents from thirteen species of cultured freshwater fishes in China.The DNA contents of black carp (Mylopharyngodon piceus),glass carp(Ctenopharyngodon idellus),silver carp(Hypophthalmichthys molitrix) and bighead carp(Aristichthys nobilis) were 2.20,2.18,2.18 and 2.15pg/N respectively,which showed no significant difference between each two of them.Three common carps,Xinguo red carp(Cyprinus carpio var singuonesis),C.carpio with mirror carp and C.carpio with red colour,almost had the same content, 3.80,3.73 and 3.76pg/N respectively and no significant difference was observed.Two tilapia (Sarotherodon niloticus and S.aurea) also had the similar DNA content of 2.27pg/N and 2.22pg/N.The DNA contents from rainbow trout(Oncorhynchus mykiss),amur sturgeon(Acipenser schrensch) and blunt snout bream(Megalobrama amblycephala )were 3.47,11.73 and 2.66pg/N.respectively. Finally,the determination of systematic relationship of fish species from the DNA contents was suggested. |
