  • Gammaropsis utinomii (Nagata, 1961), an incompletely known species of gammaridean amphipod, is redescribed in detail based on the specimens from the southern coast of Korea. The expanded basis of pereopod 7 of this species allows it to be distinguished from its congeners.

  • This study was conducted to figure out the nutritional nature of seafoods categorized according to the medicinal effects and the usages introduced in Lim-Won-Sib-Rheuk.-Ji, one of the well-known encyclopedias published during the Chosun Dynasty. They were compared with those introduced in other cooking books in order to find out how they were used in the diet of real-life. The seafoods of the book were first categorized into the fish 20, the mollusk 5, the crustacea 4, and the shellfish 7, and reptile according to the biological taxonomy, and then each one was reviewed in terms of the taste and the food-nature. Generally, the fishes had the sweet taste; the crustacea and the shellfish the salty or sour in addition to the sweet taste; none of them were bitter or hot. Most of them had the mild nature; seven of them were regarded as warm; four as cool; one as cold from the standpoint of the traditional medicine. The food-nature of seafoods was closely related with the medicinal effects on the human body. These seafoods were characteristically used in daily dietary life as well as the medical applications; used as the side-dishes rather than the main-dishes. The cooking methods of boiling, steaming, and baking were preferred to drying and stewing. The preservation methods favored were the fermentation, drying and salting. These cooking and preservation methods were believed to reflect the nature of the seafoods to manifest the medicinal effects.

  • Proximate composition, sterol and $\alpha$-tocopherol ($\alpha$-Toc) contents of 35 species of marine invertebrates (13 species of Bivalvia, 10 species of Gastropoda, 4 species of Cephalopoda, 4 species of Crustacea, 2 species of Ascidacea and 2 species of Holothuroidea), which caught off the coast of Tongyeong of the Southern sea (Nam-Hae), Korea, were determined. Protein content showed relatively high level in herbivorous (seaweed feeder) and carnivorous species such as Gastropoda ($17.2\pm4.30\%$), Crustacea ($16.8\pm4.06\%$) and Cephalopoda ($15.3\pm3.24\%$), but showed low in plankton feeder and mud swallow such as Bivalvia ($11.8\pm2.49\%$), Ascidacea ($8.20\pm1.00\%$) and Holothuroidea ($3.94\pm1.13\%$). Total lipid (TL) content was low in most marine invertebrates, ranged from $0.24\%$ (blue colored sea cucumbers) to $1.96\%$ (sea squirts). Ascidacea contained the largest amount of TL in all samples, while Holothuroidea contained the smallest amount of TL, and other classes contained about $1\%$ of TL. Carbohydrates was rich in plankton feeder and Herbivorous species (seaweed feeder) such as Ascidacea ($6.60\pm4.53\%$), Bivalvia ($3.15\pm1.82\%$) and Gastropoda ($3.02\pm1.61\%$), while poor in carnivorous species such as Crustacea ($0.52\pm0.57\%$) and Cephalopoda ($1.00\pm0.63\%$). Moisture content was highest in Holothuroidea ($92.0\pm1.94\%$) and the lowest in Gastropoda ($77.0\pm1.95\%$): There were negative correlations between moisture and protein content, or TL, between protein and TL content; y= -0.8716x+184.452 (r=-0.87, p<0.001), $y=128.52e^{-0.0601x}$ (r=-0.55, P<0.001), $y=6.3047e^{-0.0904x}$(r=-0.42, P<0.02), respectively. Sterol content was ranged from 56 mg/100 g edible portion of red colored sea cucumbers to 216 mg/100 g edible portion of cockle and was high in the following order; Cephalopoda (148 $\pm$30.0mg)>Bivalvia (121$\pm$35.0mg)>Gastropoda (118$\pm$20.0mg)>Crustacea (116$\pm$31.0mg)>Ascidacea (78.0$\pm$2.00 mg)>Holothuroidea(62.0$\pm$8.00 mg). Crustacea contained 1$\~$2 mg $\alpha$-Toc/100 g edible portion whereas other classes contained trace or less than 1 mg/100 g of edible portion.

  • In this study, we conducted field surveys to investigate and analyze species and length composition of catch from gape net with wings being set in two areas - Masari, Supomri - located in southern part of Jin-do for understanding fishing characteristics of gape net with wings fishery from March to September of 2011. And with those results, we attempted to propose fishery management strategy to harvest fisheries resources continuously. Catch obtained from field surveys comprised total 78 species, which accounted for 53 species of fish, 20 species of crustacean, 4 species of cephalopod and one of polychaete. As to species composition in weight, it showed that there was 88.5% for pisces, 9.0% for cephalopoda and 2.5% for crustacea. As to catch specifics by area, there was 36 species (596,891 individual, 456,551g) of pisces, 17 species (35,815 individual, 12,909g) of crustacea and 3 species (2,876 individual, 3,004g) of cephalopoda in Masari area. In Supumri area, there was 41 species (396,898 individual, 281,457g) of pisces, 15 species (16,113 individual, 7,772g) of crustacea and 4 species (6,792 individual, 72,329g) of cephalopoda and one polychaeta (36 individual, 11g). Catch of anchovy by month recorded on high level on June, July, September in both areas. When considering size composition by month, it was found that new populations recruit to these fishing grounds on June and September. Most of bycatch species including hairtail (Trichiurus lepturus), dotted gizzard shad (Konosirus punctatus), conger eel (Leptocephalous), Pacific sandlance (Ammodytes personatus), horse mackerel (Trachurus japonicus) were juvenile, and grass puffer (Takifugu niphobles), Kammal thryssa (Thryssa kammalensis), Japanese sardinella (Sardinella zunasi) were also small in size. As a result, it is considered that gape net with wings fishery which is likely to catch juvenile needs to be set fishing prohibit period for conserving above stocks during the period excluding main fishing periods of anchovy or fisheries management such as expanding mesh size for preventing juvenile catch.
