The United States is Korea's important trading partner, ranking third (13.7%) in exports of fishery products in Korea. The impact on exports to the United States is expected to be significant if the seafood import provisions under the MMPA are implemented in 2024 accordingly. It is expected that documents proving production information will be required for all items when exporting to the U.S. Therefore, this study attempted to examine the current status of exports and exporters in order to understand the actual conditions of major fishery products exported to the United States. Besides, there are currently no official system and procedures in Korea to prove production information for all fishery items, so we tried to suggest implications by examining distribution channels for major export items to the U.S. In this study, five items including seaweed and halibut as domestic aquaculture items, tuna and squid as deep-sea fishing items, and fish cake using imported raw materials were selected as the target items for distribution channel investigation. In addition, this study is meaningful in that it investigated the routes from production to processing, distribution, and export of each item and identified detailed distribution channel for major items exported to the U.S.

The content of the trace metals in the cultured and wild fishes were determined. The tested fishes were genuin porgy (Pagrus major) and black porgy (Acanthopogrus schlegeli). The samples of the cultured and wild fishes were collected from slices of raw fish in shops, during 2003 to 2004. The samples were digested with acids, then analyzed by ICP (inductively Coupled plasma Spectrometer) and AAS (Automic Absorption Spectrometer) for the content of lead (Pb), cadmium (Cd), arsenic (As), copper (Cu), manganese (Mn) and zinc (Zn). The content of mercury (Hg) was determined using mercury analyzer. The mean contents of trace metals in cultured and wild fish was 0.031,0.047mg/kg far total-mercury,0.321,0.407 for Pb, 0.048,0.063 for Cd, 1.006, 1.132 for As, 0.467,0.806 for Cu, 0.233, 0.293 for Cr, 9.69, 12.20 for Zn,0.798, 0.624 mg/kg far Mn, respectively. The content of all the trace metals except manganese in wild fish was more than that in cultured fish. The highest level of total-mercury, lead, cadmium, zinc, chromium and arsenic in the samples analyzed were all below the quarantine limit of Korean regulation and guideline established by the U.S. Food and Drug Administration f3r human consumption. The level of the trace metals in the samples was negligible, which could be endogenous. Our data obtained in this study showed that the average weekly intakes of lead, cadmium and mercury from cultured and wild fishes takes about $6\∼13\%$ of Un(Provisional Tolerance Weekley Intakes) that FAO/WHO Joint Food Additive and Contaminants Committee has set to evaluate their safeties.

Background: This study aimed to evaluate the impact of a community-based health education and communication programme on reducing liver fluke infections caused by the consumption of uncooked fish among people in a high-risk area of Thailand. Materials and Methods: The study was quasi-experimental in nature, with three-stages. Stage 1 involved a situational and capacity analysis of designated communities in Khon Kaen province. This was followed by the development of a model for community-based health education and communication to prevent liver fluke infections among high-risk people, and, lastly, implementation and evaluation of the model were performed. Data were collected using both qualitative and quantitative methods. In total, 390 people were surveyed, and quasi-experimental and comparison groups, each with 90 people, were assessed between May 2011 and April 2012. Analysis was using statistical OR, 95 % CI, the Willcoxon matched pairs signed ranks test, the chi-square test, and the Mann-Whitney U test. Results: The findings showed that most respondents had a high level of knowledge and understanding of liver fluke disease (89.5%, 95% CI:86.0-92.4), and positive attitudes toward the prevention of the disease (94.4%, 95% CI:91.6-96.4). However, with regard to changes in consumption of uncooked fish, most respondents were still in the pre-contemplation phase (55.1%, 95% CI:50.0-60.1), followed by the contemplation phase, 22.6%. Furthermore, four factors were found to be associated with the consumption of uncooked fish - the consumption of alcohol (OR 4.16, 95% CI:1.79-9.65), gender (OR 3.17, 95% CI:1.53-6.54), smoking (OR 3.03, 95% CI:1.31-7.05), and age 40 years and above (OR 2.68, 95% CI:1.02-7.05). After nine months of the health education and communication programme using local media based on local wisdom, culture and persons, the results showed that, compared to the control group, members of the experimental group had a higher level of knowledge, a better attitude and lower levels of ill-advised consumption behaviour. Also, it was found that consumption of uncooked fish, by an assessment of the level of stage of change, was reduced. (p-value 0.002). Conclusions: The health education and communication programme developed as part of the study was effective in changing the consumption of uncooked fish. Therefore, this approach should be promoted in other high-risk areas in Thailand in the future.

Fish-frames, which are left after obtaining fillets or muscle during fish processing, consists of useful food components, such as muscle, collagen, calcium, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). This study was carried out to prepare snack using conger eel frame (SF) for human consumption and also to elucidate food component characterization of the snack. The results of volatile basic nitrogen suggested that conger eel frame was a suitable material for preparing snack. Based on the results of sensory evaluation and costs, starch syrup was an optimal sweetener for preparing snack using conger eel frame. The starch syrup-treated SF appeared safe because the moisture content and peroxide value were below the safety limits described in the guideline of Korea Food and Drug Administration (KFDA). Starch syrup-treated SF was similar in the pattern of fatty acid composition to soybean oil, whereas EPA and DHA were detected in SF. The total content of amino acid in starch syrup-treated SF was 23.9% based on 100 g of raw material. The maj or amino acids were aspartic acid, glutamic acid, glycine and alanine. The total contents of calcium and phosphorus in starch syrup-treated SF were 4.9% and 2.8%, respectively. The Ca/P of starch syrup-treated SF was 1.9, which is a good ratio for absorption of calcium. The SF made with starch syrup was superior in EPA and DHA compositions, total amino acid, calcium and phosphorus contents to commercial snack using eel frame.

This study was carried out to investigated the quality characteristics of kimchi, made by adding blue crab. Kimchi is made into a fermented vegetable food by adding red pepper powder, garlic, ginger and fermented salted fish to the salted cabbage or radish. Chitin/chitosan, found in the shell of crab is the biopolymer. Chitin possesses many beneficially biological properties. Salt consumption impacts on human health problems such as hypertension and cardiovascular disease. In this study, we hypothesized that kimchi added with raw blue crab would reduce excessive salt consumption and increase protein supplementation. We analyzed lactic acid bacteria level, pH, acidity, salinity and free amino acid of kimchi added with blue crab during 1, 15 and 30 days storage period at $5^{\circ}C$. Lactic acid bacteria, pH, salinity increased significantly in kimchi added with blue crab compared to the control. Accordingly, this result suggested that kimchi should be manufactured by adding raw fish rather than fermented salted fish.

In order to effectively utilize the fish and squid skin wastes derived from marine processing manufacture, the skin wastes of some pelagic fishes such as yellowfin sole, red cod, cod, Allaska pollack and flying squid were screened for the raw material of edible gelatin and studied some properties of those gelatins. The content of total collagen in the red cod skin was the highest (28.4 g/100 g wet skin), while that in the flying squid skin was the lowest (11.1 g/100 g wet skin) and those of another fishes were similar. Acid soluble collagens in the skins of the fishes and flying squid were $68.9\~84.8\%\;and\;44.3\%$, respectively. But showed no difference in the amino acid composition between acid soluble and insoluble collagens. Those collagens were consisted $\alpha\;and\;\beta$ chain and $\alpha$ chains extracted from fish skins except red cod and flying squid skins were hetero. The collagen of yellowfin sole skin exhibited slightly higher denaturation temperature $(25.4^{\circ}C)$ and also physical properties such as gel strength, melting point and gelling point were better than those of the other species.

This study was performed to investigate the prevalence and its related factors on the Clonorchis sinensis(C.S.) of inhabitants at Goksung-gun, Chollanam-do. After the population was stratified by gender, age, resident area, 651 residents living in eight villages were sampled by cluster sampling method. We interviewed the subjects to survey the various characteristics using the questionnaire, and examined stools to confirm the infection of C.S. from November to December, 1998. The prevalence of C.S. was 19.0%. The factors related with the infection of C.S. were male(adjusted odds ratio, of female=1.71, 95% confidence interval=1.07-2.72), 45-64 year old group(aOR of under 45 year old group=2.16. 95% CI=1.21-3.85), above 65 year old group(aOR of under 45 year old group=2.34, 95% CI=1.31-4.15), basin villagers(aOR of inland villagers=2.34, 95% CI=1.31-4.15), current drinker(aOR of nondrinker=1.83, 95% CI=1.12-2.98), those who took raw fish(aOR of persons who didn't it or take cooked fish=2.09, 95% CI=1.21-3.88) and persons who know the infection status(aQR of the persons who didn't know it=0.57, 95% CI=0.37-0.89). In conclusion, these results suggest that several life styles such as ingestion of raw fish, drinking habit. So we think that it is necessary to set up the efficient management programs for the treatment and prevention of C.S. infection.

In this study we sought to determine the food fraud by discriminating species of commercial seafood product such as Larimichthys polyactis, Larimichthys crocea, Pennahia argentatus, and Miichthys miiuy, which are difficult to morphologically discriminate. After amplifying the mitochondrial cytochrome c oxidase subunit I gene of the reference fish, the DNA sequences of the amplified PCR products were analyzed. As a result, a 655 bp sequence for species identification was selected for use as DNA barcodes. To confirm the DNA data and primer set, the DNA barcode sequence of each fish was compared to that in that in the NCBI. All of the DNA barcode data were matched with the gene sequence of each fish in the NCBI. A total of 32 processed seafood products (8 L. polyactis, 12 L. crocea, 3 Pennahia argentatus, and 9 Miichthys miiuy) were investigated. Homology of 97% or more in DNA sequences was judged as the same species. As a result of the monitoring, there were no discovered cases of forgery or alteration. However, the use of a raw material name having no matching standard name in the Korea Food Code may cause consumer confusion. Therefore, it is suggested that the standard name or scientific name be co-labeled with the raw material name on seafood products to prevent consumer confusion.

Fish-meat gel is an intermediate product used in a variety of surimi-based seafood. One of the most-used raw materials of fish-meat gel is Alaska Pollock due to its high-quality meat in terms of gel strength and texture. However, increasing demand for fish-meat gel, along with overexploitation of the wild catch Alaska Pollock, has put the industry in need of low-cost sustainable alternative sources for fish-meat gel. Pagrus major (PM) is a widely aquacultured fish known for having white meat that is low in fat. The current study compares the quality of fish-meat gel prepared from aquacultured PM to that of high and mid-grade Alaska Pollock fish-meat gel. Gels were compared in terms of gel strength, texture, color, and protein pattern. Results indicated that fish-meat gels prepared from PM were superior to Alaska Pollock fish-meat gels with regard to gel strength, hardness, springiness, chewiness, cutting strength, and breaking force. In addition, although not matching in quality, PM exhibited a cohesiveness, whiteness, and expressible moisture content comparable to Alaska Pollock of both grades. Protein pattern analysis also showed that PM and Alaska Pollock fish-meat gels had similar protein profiles before and after gel preparation. Therefore, P. major is suggested as a potential substitute for Alaska Pollock in fish-meat gel production.
