This study was conducted to prepare curry potato pancakes (CPP), curry fish balls (CFB) and steamed eggs (SE) using Pacific saury Cololabis saira as senior-friendly seafood and to determine the physical property stages and quality characteristics of the prepared food. Escherichia coli concentrations were undetected in all the products, which is considered an acceptable limit for senior-friendly foods. On applying the physical properties standards according to the Korean Industrial Standard, saury CPP, saury CFB, and saury SE were classified as the 1^st, 2^nd, and the 3^rd stages as senior-friendly seafood, respectively. Regarding the nutritional properties per 100 g of the three types of senior-friendly seafood using saury according to the Korean food code, CPP had three types of nutrients (protein, riboflavin, and niacin), whereas CFB and SE had four (protein, riboflavin, niacin and calcium) and six (protein, vitamin D, vitamin C, riboflavin, niacin, and calcium) types of nutrients, respectively.

Thousands of pelagic and demersal fishes inhabit the waters around Korea and many of them are overexploited. One of the reasons is technological development, which increases the efficiency of the vessels continuously. The analysis was conducted to identify the change of fishing power index to develop the vessel and gear technology that may have improved the fishing efficiency of the otter trawl fishery from 1960s to 2010s. Gross tonnage was decreased stably, but horse power was increased annually. The perimeter of net mouth was somewhat longer, but little changed. Color fish finder was utilized from the mid-1960s. Hydraulic net drum were introduced in the early 1990s, and supply rate was gradually increased. Surveys on the supply and upgrading of fishing equipment utilized visiting research. Therefore, the relative fishing power index in the trawl fishery increased about two to three times in the 2010s compared to the 1980s. The results are expected to contribute to reasonable fisheries stock management.

This study investigated the concentration of total mercury in 17 species of commonly consumed fishes and assessed the risk to human health from provisional tolerable weekly intakes PTWI% as affected by migratory characterization, such as migration and vagility. The measured mean concentrations of total mercury in these 17 species of commonly consumed fishes suggest that mean concentrations of total mercury in 10 species of migratory fishes (largehead hairtail, chub mackerel, Pacific saury, skipjack tuna, Pacific cod, anchovy, Alaska pollack, brown croaker, Japanese Spanish mackerel, yellow croaker and Pacific herring) were low compared to those in 7 species of demersal fishes (red stingray, brown sole, bastard halibut, conger eel, blackmouth angler, rockfish and filefish). Based on the mean concentrations, the PTWI% of total mercury among commonly consumed migratory fishes was 3.393%, which was higher than that of commonly consumed demersal fishes (2.710%).

This study is aimed to present measures for stable supply of fishmeal and to develop fish farming into a food industry and an export industry. The study analyzed current domestic and international supply and demand for fishmeal and suggested future prospects. The results of the study suggested the basic directions for the stable supply of fishmeal in Korea as follows: first, stable securing of fishmeal importers and establishment of the supply and demand monitoring system; second, policies to boost using of compound feeds and expansion of relevant fishmeal use; third, higher competitiveness of fishmeal and compound feeds through selective and intensive R&D investments. Based on the basic directions, the paper suggested implementation measures such as strengthening of cooperations with fishmeal suppliers abroad, expansion of overseas local market entrance, diversification of fishmeal trading countries, revision of relevant laws and polices on the fishmeal and feeds, organization of domestic fishmeal, promotion of group purchase, improvement of domestic fish meal quality, development of fish meal alternatives, etc.

The sudden drop of water temperature in winter is very threatening factor that affects the productivity of farmed fish and the management in aquafarm. In this study, we investigated the effect of low temperature on the survival, oxygen consumption and stress responses of parrotfish Oplegnathus fasciatus due to acute drop of water temperature. The survival rate of parrotfish Oplegnathus fasciatus was 5% at 6℃, 95% at 8℃ and 100% at 10℃ on the 4^th day of exposure in each experimental temperature. Low-lethal temperature for 4days of parrotfish Oplegnathus fasciatus (4 day-LT₅₀) was 6.99℃ (confidence limit, 6.55-7.42℃). Oxygen consumption rate was significantly decreased with decreasing water temperature. Temperature coefficient (Q₁₀) was found to be 4.0 between 10℃ and 8℃ and 0.39 between 8℃ and 6℃. As a result of investigating the stress response according to the drop in water temperature, the concentration of SOD (Superoxide dismutase), cortisol, glucose, total Ig, AST (Aspartate) and ALT (Alanine aminotransferase) increased with decreasing of water temperature. This study would be useful for the management of temperature about cultured fish.
