This study was carried out in order to elucidate the fundamental data on the taste compounds between wild and cultured fishes produced on Chungmu and Wando at the southern coast areas of Korea. For this purpose, the food components of cultured fishes such as red sea bream Pagnus major, Sebastes pachycephalus and flounder, Paralichthys olivaceus being spot lighted for the main sea fish, the staple food and high economic fish were investigated and compared with those of the wild ones. There was a little appreciable difference in the proximate compositions of all the species from localities between wild and cultured fishes. But according to the growing conditions, wild fishes were higher in moisture contents and lower in crude lipid content than those of cultured fishes and little difference was seen in protein and ash contents between the two. With regard to the nucleotides and their related compounds, i.e. ADP, IMP and inosine were detected but ATP and hypoxanathine were not from them. On the other hand, there were little difference in the total taste compounds of all the species from localities and the growing conditions between wild and cultured fishes. But all the species were higher in IMP content. The total of seventeen amino acids were detected in samples. The highly contents of glutamic acid, lysine, aspartic acid, proline, leucine, alanine, valine and alginine were showed and less low contents of cystein, histidine, methionine, tyrosine and phenylalanine were detected. The total amino acids of the others were much alike in that composition. Little difference was seen from localities and the growing conditions between wild and cultured ones. The free amino acids were much alike in that composition of all the species. There was little difference in the free amino acid compositions all the species from localities and the growing conditions between wild and cultured fishes. But taurine was dominant, showing from 39% to 65% of the free amino acid content and it is followed by hydroxyproline, lysine, alanine and glycine in other. There were differences in the organic acid compositions of all the species from localities and the growing conditions between wild and cultured fishes. In addition, cultured fishes were more abundant in the total organic acid compositions than those of wild ones.

Fish assemblage structure in a sheltered shallow water in the Southern Coast of Korea was examined monthly. Sampling was conducted in Doam Bay using a beam trawl between March 2001 and February 2001. A total of 53 fish species from 33 families were caught. Pinkgray goby (Chaeturichthys hexanema), ponyfish (Leiognathus nuchalis) and yellowfin goby (Acanthogobius favimanus) were the most frequent species, comprised 67.4％ of the total numbers captured. Snailfish (Liparis tanakai), yellowfin goby (Acanthogobius flavimanus) and pinkgray goby (Chaeturichthys hexanema) represented 50.8％ of the total biomass. While total abundance (number of individuals) and biomass were high in autumn and winter, species richness (number of species) and diversity were high in spring. Cluster analysis, based on monthly abundance data of the 14 most frequent species, showed that the species were separated into three different groups. Group A composed of pinkgray goby, yellowfin goby, robust tonguefish (Cynoglossus robustus) and scaly hairfin anchovy (Setipinna taty), which were year-round residents, and devil flathead (Onigocia spinosa), Red dragonet (Repomucenus lunatus) and ponyfish, which were abundant in autumn, group B surmullet (Upeneus japonicus), hairtail (Trichiurus lepturus) and gaff-topsail goby (Cryptocentrus filifer), which were abundant in summer, and group C grassfish (Liparis tanakai), spotted velvefish (Erisphex pottii), chameleon goby (Tridentiger trigonocephalus) and Richardson dragonet (Repomucenus richardsonii), which were abundant in winter and spring. A seasonal homogeneity of fish assemblage indicates that overall fish assemblage in Dom Bay is largely controlled by year-round residents.
