Abstract:131 live left-eyed flounders, Paralichthys olivaceus (T. ET S.), were collected from the coastal waters of Qingdao and a fishing farm in Rongcheng City, Shandong Province from May in 1996 to April in 1998. In total, 710 biochemical samples from 6 tissues and organs (eye, muscle, heart, liver, pectoral fin and kidney) were fetched and stored immediately in liquid nitrogen (-196°C). The supernatant of samples to be used for the experiments were extracted by homogenizing and centrifuging. 15 isozymes (LDH, MDH, MEP, IDHP, G3PDH, AK, CK, ACP, PGM, SDH, ADH, CAT, SOD, GDH, GPI) in 3 buffer systems (TC, pH=6.9; EBT, pH=8.9; TG, pH=8.3) were tested by horizontal starch gel and vertical polyacrylamide gel electrophoresis, and their expression in 6 tissues and organs-tissues specify was also tested. The biochemical genetics were analyzed in terms of their locus number, structure, alleles, etc., on the basis of which the basic electrophoretic patterns of these 15 isozymes were gained. The electrophoretic patterns of the rest isozymes were not recorded. Altogether 29 gene loci were recorded, among which 9 gene loci including Ldh-A(alleles, 100, 167), Ldh-C(alleles, 98, 100), Idhp-1(alleles, 78, 100), Acp-1(alleles, 78, 100), Pgm(alleles, 100, 200), Sdh(alleles, 100, 125), Adh(alleles, 70, 100, 150), Cat(alleles, 93, 100, 140) and Gdh(alleles, 100, 130) are polymorph, and the mean proportion of polymorph loci was 31.03%. in the meantime, the expression of Ldh-A and Ldh-B during the biochemical genetic analysis of LDH on Paralichthys olivaceus (T. ET S.), the interrelationships between the activities of isozymes protein and stored condition of samples, and testing of effective genetic markers were also discussed.
