Many people living in Asia countries, particularly Korea, Japan and China, have consumed very widely fresh seafood products, such as shrimps, oysters, mussels and other marine invertebrates and fishes, without any heating or cooking. A variety of Vibrio spp., including V. parahaemolyticus, V. cholera. V. vulnificus, and V. fluvialis, lives in these seafoods and cause great problems associated with human disease. A strong antimicrobial agent to effectively inhibit the growth of these pathogenic bacteria in in vivo or in vitro is urgently need for preventing fish and human diseases. (omitted)

This study investigates the WTO dispute over Japanese fishery products originated from Fukushima and another seven prefectures. Being subject to an import ban and additional radioactive test requirements, Japan complained that the Korean government's trade measures are inconsistent with the principles of the Agreement on Sanitary and Phytosanitary Measures. This paper considered the contrasting judicial decisions made by the Panel and Appellate Body and analyzed the debates with respect to their trade-discriminatory effects (Article 2.4), the relevance of appropriate level of protection (Article 5.6) and the precautionary approaches (Article 5.7). Consistent with the final rulings, this paper identifies the need for a broaden understanding of regional conditions and qualitative aspects of protection in risk analysis. Findings also suggest that Korea has diverted its fishery imports from Japan to other countries, while Japan has created export diversion from Korea to other destinations.

This study aimed to determine mercury (Hg), methylmercury (MeHg), and selenium (Se) levels in deep-sea fishes distributed in Gyeonggi-do, South Korea. Concentrations of Hg, MeHg, and Se were measured by using a mercury analyzer and Inductively Coupled Plasma - Mass Spectrometry (ICP-MS). The average content (mg/kg) in the seafood samples was as follows: Hg, 0.7647 (0.0182-5.3620), MeHg, 0.0764 (0.0096-0.8750), and Se, 0.4728 (0.1075-3.5100). All the levels of MeHg were below the recommended standards of the Ministry of Food and Drug Safety i.e., <1.0 mg/kg. Recent studies have shown that Se prevents Hg toxicity. The average daily intake in humans was 3.3 ㎍/kg, which was lower than the recommended amount (50-200 ㎍/person/day). The weekly intake of Hg and MeHg was calculated to be 6.07% and 1.90%, respectively, of the provisional tolerable weekly intake (PTWI). This study showed that the weekly intake of Hg and MeHg from abyssal fish was less than the PTWI recommended by the Joint FAO/WHO expert committee on food additives. Therefore, the levels reported in this study are presumed to be adequately safe.

As a part of investigation for utilizing seafood processing by-products as a functional food source, we investigated the processing condition (extraction methods and autoclaving time) of a functional calcium-based powder from fish bones and its characteristics. The calcium-based powder from Alaska pollack bone by autoclaving in water showed lower in the calcium content and higher in the yields and the soluble calcium ratio than those from fish bone by the other calcium extraction methods. As the autoclaving time elapsed up to 40 min, the content and soluble ratio of calcium increased, and the yield decreased. On the other hand, there were no difference found in those among calcium-based powders autoclaved for 40 min and over. Judging from the results, the calcium-based powder from Alaska pollack autoclaved in water for 40 min (CAP) was superior to those from fish bone by the other processing condition. The CAP was mostly solublized by shaking $(37^{\circ}C)$ for 1 hr at the acidic condition (pH 2.0). The soluble calcium ratio of acid-solublized CAP was about 59% by shaking $(37^{\circ}C)$ for 3 hr and over at the neutral condition (pH 7.0).

This study was conducted to understand the quality characteristics of 20 kinds of commercial salt-fermented anchovy & sand lance sauces by measuring their the chemical compositions and 9 biogenic amines (tryptamine, 2-phenylethylamine, putrescin, cadaverine, histamine, tyramine, serotonin, noradrenaline, spermine) contents. The commercial salt-fermented anchovy sauces contained $65.84{\pm}0.11{\sim}70.60{\pm}0.21%$ of moisture, $20.50{\pm}0.41{\sim}25.60{\pm}0.42%$ of salinity, $0.98{\pm}0.01{\sim}2.05{\pm}0.05%$ total nitrogen, and $1,011.77{\pm}0.00{\sim}1,724.56{\pm}9.72mg/100mL$ of amino nitrogen. Histamine was the major amine detected in salt-fermented fish sauces and it was varied from 421.27 to 1,507.18 mg/kg in salt-fermented anchovy sauces, whereas commercial salt-fermented sand lance sauces contained $67.87{\pm}0.28{\sim}69.63{\pm}0.17%$ moisture, $22.46{\pm}0.28{\sim}26.11{\pm}0.00%$ salinity, $0.92{\pm}0.01{\sim}1.71{\pm}0.05%$ total nitrogen, $878.20{\pm}0.00{\sim}1430.09{\pm}9.77mg/100mL$ amino nitrogen and 419.10~1,025.50 mg/kg histamine, respectively. These findings suggest that the products of salt-fermented fish sauces have pretty much the same in ingredient composition and meet domestic criteria but most those had high biogenic amine contents. Therefore, ingredient composition and biogenic amine content of commercial salt-fermented fish sauce products were practicable evaluation of the quality characteristics.

Objectives: This study was carried out to provide safe seafood to the public through simultaneous analysis rapid inspections for residual veterinary drugs in 150 fishery products in 2016. Methods: Quinolones (9), Sulfonamides (14), Penicillins (2), Cephalosporins (3), Tetracyclines (4), Macrolides (4), Lincosamides (2), Pleuromutilin (1), Phenicols (4), benzylpyrimidines (2), Others (1) Malachite green (2), and Melamine (1) were analyzed for 49 species using by HPLC and HPLC-MSMS. Results: There were six unsuitable samples, five among fish and one for crustaceans. Within the standard detection were five fish. The antibiotics found were Quinolones (50%), Tetracyclines (33%) and Penicillins (17%). Conclusions: As a result of the experiment, there were six unsuitable samples, five for fish and one for crustaceans. The most prevalent antibiotics were Quinolones. The quinolone antibiotics are highly persistent in fish tissues, so they require more time than the withdrawal period for other common veterinary drugs. Careful attention is required when they are used in fish farms.

The purpose of this study is to identify problems and suggest improvements of estimating procedures and item of fisheries supply-demand statistics served as a basis for the fisheries supply-demand policies. Korea Rural Economic Institute(KREI) and Ministry of Oceans and Fisheries(MOF) respectively publish the fisheries supply-demand statistics. But the reliability of data is low as the statistics of these two organizations are limited and show discrepancy in the numbers. It is therefore difficult to use them as the basic data for policies. Also, an accurate data aggregation is difficult due to following problems in the items of statistics. 1) Problems in estimating route sales and non-route sales of production, 2) adequacy of fishery product yield rate compared to raw material in the fisheries import/export sector, 3) selection of target companies for understand stocks and survey scope of fish species, 4) applying'0'to non-edible product demand etc. In order to develop the fisheries industry as a future growth industry, it is necessary to establish the accurate fisheries supply-demand policy as the instability of fisheries supply and demand is increasing. To do this, statistical reliability has to be improved. The improvements proposed in this study should be implemented considering urgency. First of all, an exhaustive analysis of stock statistics and conversion rates of raw material yield in the fisheries import/export sector should be conducted. In the medium term and the long term, transferring production statistics to MOF and surveys on the use demand of non-food product and the level of reduced and discarded seafood products should be carried out in consecutive order.
