摘要

Abstract

The genetic diversity of both wild and rearedpseudosciaena crocea (Richardson) collected from Guan-Jing-Yang in Ningde

China in May 1999 was investigated by random amplified polymorphic DNA (RAPD) in the present study. The polymorphism and mean difference of the wild population as revealed by RAPD were 18.9% and 0.0960 respectively

and those of the reared stocks were relatively lower

with 16.7% in polymorphism and 0.0747 in mean difference. The genetic distance between the two stocks was 0.0041. From the comprehensive investigation

the main reasons for the loss of genetic diversity were probably overfishing

small number of parents as broodstocks and the debatable artificial ranching. Results from this study also showed that the large yellow croaker populations distributed along Fujian coastal waters including Guan-Jing-yang still potentially wide genetic variability. It is suggested that genetic management and prevention should be scientifically conducted in order to maintain and improve the genetic diversity of theP. crocea population.
