AFLP 분석에 의한 병어속(Pampus) 3종의 유전 변이

Genetic variation and relationship of two wild (Pampus argenteus and P. echinogaster) and one cultured (P. chinesis) pomfret fish belonging to the genus Pampus were assessed. Specimens were collected from Korea and China and subjected to amplified fragment length polymorphism (AFLP) DNA fingerprinting. Four primer combinations generated a total of 304 DNA fragments ranging from 153 to 251 bands. Polymorphism and genetic diversity of cultured P. chinensis (22.9% and 0.038) were significantly lower than the two wild species of P. argenteus (93.6% and 0.311) and P. echinogaster (94.0% and 0.290). Genetic distance ranged from 0.335 (P. argenteus and P. echinogaster) to 0.646 (P. argenteus and P. chinensis) and showed a congeneric relationship within this genus. Twenty one of specific AFLP markers from four primer combinations bands were produced. These results suggest that AFLP polymorphism may be a useful marker for genetic identification among the three species studies here.

The external morphometric characteristics of silver pomfret, Pampus punctatissimus and Korean pomfret, P. argenteus of Stomateidae in Korea were investigated through direct distance. The 16 measurements were expressed as a ratio to the total length, resulting in 8 measurements of P. punctatissimus were found to be larger than those of the P. argenteus (p<0.05). The factors by components in the morphometric characteristics were extracted into three sub-factors, among which factor 1 was length component of species division, factor 2 was length component of body shape, and factor 3 was length component of pectoral section. As for the correlation between the length factor between P. punctatissimus and P. argenteus, DFL-DH showed the highest positive correlation by 0.923. The most remarkably distinguishable factor for the morphometric trait of Stomateidae was the length in dorsal and anal fin shapes, DH and AH, which were longer in the P. punctatissimus than in P. argenteus.
