Structure and mucosubstance histochemistry in the epidermis of five teleostean species, i. e., spotty belly, Agrammus agrammus, devil stinger, Inimicus japonicus, stone fish, Erosa erosa, cubed snailfish, Liparis tessellatus, and Japanese bluefish, Scombrops boops were investigated. The epidermis of five species studied is composed of three layers: superficial, middle, and basal layer. The superficial layer is comprised of rather flattened cells. Mucous cells, the type commonly found in fishes are completely lacking in the epidermis of devil stinger, stone fish, and cubed snailfish. The epidermis of devil stinger and stone fish have multicellular glands which do not have mucosubstances. The skin surface of them is covered with mucous layer. The superficial cells in the epidermis of devil stinger, stone fish, and cubed snailfish are mucus-secreting cells. The composition and the amount of the mucosubstances vary in species and body regions. The mucous layer on the skin surface and superficial epidermal cells of devil stinger contain a mixture of neutral and acidic(sulfated and nonsulfated) mucosubstances. In stone fish, the mucous layer has acidic(sulfated and non-sulfated) mucin and the superficial epidermal cells contain neutral mucin. In cubed snailfish, the type of epidermal mucosubstances is identified as a mixture of neutral and acidic(non-sulfated) mucin. The mucous cells of the epidermis in spotty belly and Japanese bluefish contain neutral mucin.

Two species of demersal fish, Liparis tessellates (cubed snailfish) and Hemitripterus villosus (shaggy sea raven), were investigated in relation to seasonal chemical composition. Total fat contents of the two fish were very low and were not appreciably different throughout the year, whereas their fatty acid compositions were significantly different depending on season. Noticeable changes in the moisture and protein contents in the two fishes were observed before and after spawning. Cubed snailfish showed relatively high amounts of total amino acids and free amino acids during summer months, whereas the levels of those in shaggy sea raven remained relatively unchanged throughout the year. Regardless of season, the major fatty acid of the two fishes was palmitic acid and most of polyunsaturated fatty acids (PUFAs) were n-3 PUFAs. Lead was over the legislative limit in some samples of the two fishes.

Liparis tessellatus(cubed snailfish), Hemitripterus villosus(shaggy sea raven), Ligularia fischeri, and Cirsiu setidens, which are staple products in Samcheok, were studied as food resources for the development of a representative local menu. Thus, their nutritional compositions were analyzed, and the resulting values were used to assess the nutritional characteristics of the newly-developed menu. In Liparis tessellatus and Hemitripterus villosus, the organic components including protein and fat tended to be lower than the corresponding values referred to as the 'Seventh Revision Food Composition Table' (2006), which was presumably linked to the spawning period of the fish. The contents of Zn, Cu, and Mg, which are nutritionally important even though the consumption of these minerals by Koreans is not sufficient, were determined to 0.5, 0.2, and 34.3 mg/100 g for Ligularia fischeri, and 26.2, 1.1, and 147.7 mg/100 g for dried Cirsiu setidens. Cirsiu setidens cultivated in Samcheok contained noticeably higher amounts of calcium, zinc, and iron, and its calcium level was more than an order of magnitude higher than that provided by the Food Composition Table. This might be associated with the fact of that Samcheok is abundant in lime which consists of calcium-containing inorganic materials. n-3 fatty acids including docosahexaenoic acid(DHA) accounted for 21% and 13% of the total fatty acids, for Liparis tessellatus and Hemitripterus villosus, respectively, and the major amino acids were glutamic acid, aspartic acid, glycine, and alanine for both fish. One of the newly developed menus, Cirsiu setidens hae-jang-gook, was nutritionally superior to the corresponding menu that used dried radish leaves, a typical ingredient in hae-jang-gook, in terms of the protein, iron, and zinc contents. Rice pottage cooked with Liparis tessellatus instead of abalone was high in protein, calcium, iron and zinc, where one serving provided 29.1, 15.4, 31.0, and 27.8% of their Reference Intake (RI)s, respectively.
