This study was conducted to compare the food quality of domesticated species. Consumers surveyed for safe food intake and proper culture of food distribution. The results of the comparison study are as follows. Muscle moisture content, protein content, and fat content. K, P, and C showed relatively high values in the muscle of the sea bream. Fe showed low contents. As a result of measuring heavy metal component, Cd was not detected in sea bream and mullet, but $0.01{\pm}0.00mg/kg$ was detected in red mine. Other heavy metals were below the reference value or were not detected. Electrophoresis results showed that the band appeared at in red minefish. In the case of sea bream and swordfish, no distinctive features of the band were shown. In the case of sea bream, there was little difference in food science between the similar fish species and the red sea bream fish, but price was different. An environment should be created for consumers to buy the right ingredients at the price they want. It is necessary to educate consumers about food ingredients immediately.

Silver croaker (Pennahia argentata) is a turbulent species that is widely distributed worldwide and is mainly found in the bottom of the ocean. In the study, we characterized the cytochrome c oxidase subunit I (COI) gene of the mitochondrial DNA (mtDNA) on P. argentata inhabiting Gwangyang Bay and analyzed the phylogenetic location of marine fish species. As a result of multiple arrangement of 605 bp COI sequences, high homology of mtDNA nucleotide sequences was confirmed in the silver croakers from Gwangyang Bay (98~100%). However, the nucleotide variation was different according to the catching points of the inland and the open seas of Gwangyang Bay. The nucleotide sequence variation in COI was high in P. argentata from the open seas of Gwangyang Bay (43.2~70.3%). Furthermore, the phylogenetic analysis of 13 fish showed that P. argentata from Gwangyang Bay were grouped into one clade with P. argentata reported in Taiwan, and the evolutionary distance was 0.036. In addition, it was identified that the evolutionary distance was close to that of fish belonging to the Mi-iuy croaker (Miichthys miiuy) and the Big-head pennah croaker (Pennahia Macrocephalus) (0.041~0.048). The result of these studies will be used as the key genetic information for fisheries resources monitoring and species diversity management according to the coastal environment.

In order to rapidly identify four drums species, Larimichthys polyactis, L. crocea, Atrobucca nibe, and Pseudotolithus elongates, a highly efficient and quick method has been developed using multiplex polymerase chain reaction (PCR) with species-specific primers. Around 1.4 kbp of the mitochondrial COI gene sequences from the four drums species were aligned, and species-specific forward primers were designed, based on the single nucleotide polymorphism (SNP). The optimal conditions for PCR amplification were selected through cross-reactivity, using a gradient PCR method. The PCR results demonstrated species-specific amplification for each species at annealing temperatures between 50 and $62^{\circ}C$. Multiplex species-specific PCR (MSS-PCR) amplification reactions with four pairs of primers were performed for sixteen specimens of each species. MSS-PCR lead to a species-specific amplification of a 1,540 bp fragment in L. polyactis, 1,013 bp in A. nibe, 474 bp in L. crocea, and 182 bp in P. elongates, respectively. The four different sizes of each PCR product can be quickly and easily detected by single gel electrophoresis. The sensitivity of the MSS-PCR of the DNA was up to $0.1ng/{\mu}l$ as a starting concentration for the four different species tested. These results suggest that MSS-PCR, with species-specific primers based on SNP, can be a powerful tool in the rapid identification of the four drums species, L. polyactis, L. crocea, A. nibe, and P. elongates.

In order to identify hard distinct 12 fish species(shiba shrimp Metapenaeus joyneri, fleshy shrimp Penaeus orientalis, ridgetail prawn Palaemon carinicauda, yellow croaker Pseudosciaena manchurica, croaker Niber albiflora, Colichthyes fragilis, brown sole Limanda herzensteini, frog flounder Pleuronichthys cornutrs, Areliscus rhomaleus, stone flounder Kareius bicoloratus, harvest fish Pampus argenteus, flag fish Goniistius zonatus) by seeing with naked eye in Kunsan coastal area, sarcoplasmic protein in the supernatant was used for isoelectric focusing. For getting supernatant, fish muscle tissue was blended with two times deionized water and centrifuged (at $4^{\circ}C$, 12,000rpm for 15min). Isoelectric focusing of sarcoploasmic protein carried out on a LKB Multiphor II using polyacrylamide gel plate (2mm thickness, pH $3.5~10^{\circ}C$, pH 5~8 gradient, at $10^{\circ}C$ for 1.5, 3 hours). In case of uncertain protein pattern, pH gradient was modified to narrow pH gradiet, and excuted 2-D electrophoresis using conventional polyacrylamide gel electrophoresis. Most of fishes except yellow croaker and Collichthyes fragilis were distingushed by isoelectric focusing. The protein maps of 2-D electrophoresis for analyzing two protein bands at aimilar positions(pH 5, 6) between the two fish species showed the diffeences of the estimated molecular weights, 11,700(pH5.0) and 87,000(pH6.0)

The purpose of this study is to investigate the distribution of toxin genes and antimicrobial resistance of Vibrio parahaemolyticus isolated from seafood in Gwangju. A total of 335 seafood, including 163 shellfish, 97 fish, and 36 mollusk, were tested in this study. As a result, V. parahaemolyticus was detected in 123 (36.7%) of 335 seafood. The tdh gene was not detected in all strains, while the trh gene was detected in 3 strains (2.4%). According to antimicrobial susceptibility test, 116 strains (94.3%) represent resistance to ampicillin, and 1 strain (0.8%) represents resistance to trimethoprim/sulfametoxazole. However, all strains were sensitive to 9 antimicrobial agents, including amikacin, chloramphenicol, tetracycline, and more. Therefore, the risk of V. parahaemolyticus isolated from seafood in Gwangju is considered low, but continuous monitoring of V. parahaemolyticus in seafood is required.

Fish fauna of fishes collected from the Saemankum area in the west coast of Chollabuk-do was studied from October 1996 to April 1999. The specimens collected from the five sites in this area were identified into 107 species belonging to 83 genera and 52 families. Of them the largest group of fishes was order Perciformes, comprising 50 species and 21 families, and showed 46.7% in total numbers of species. Next larger groups were orders Scorpaeniformes and Pleuronectiformes containing 16 and 14 species respectively. In this area, the group comprising a lots of species was the family Gobiidae taking 13 species, and next groups were the families of Sciaenidae (6 species), Engraulidae (5 species) and Pleulonectidae (5 species). The dominant species was Engraulis japonicus which is 23.4 ％ in total indiyidual numbers, and subdominant species was Thryssa kummazensis which is 18.5%. The important species economically in the Saemankum area were Anguilla japonica, E. japonicus, T. kummalensis, Konosirus punctatus, Sardinella zunasi, Mugil cephalus, Argyrosomus argentatus, Pseudosciaena polyactis, Collichthys lucidus, Paralichthys olivuceus and Cynoglossus joyneri.
