This study proposed the introduction of the block grant in agriculture, forestry, and fishery sectors so that the local governments get greater autonomy in agricultural policy. First of all, theoretical background on block grant was reviewed and present situation in Korea regarding block grant was examined. Four criteria were set to evaluate the eligibility for the block grant. Four criteria imply that block grant is more appropriate with small-scaled similar projects, high locality projects, easily evaluated projects, and easily formula-applied projects. Applying these criteria to the projects subsidized by the national government, appropriate projects as the block grant were selected. Finally, specific operation scheme of the block grant was proposed.

An ecosystem-based fisheries management (EBFM) approach becomes more important as an alternative management method for a sustainable development of fisheries domestically and internationally. Many methods of applying a practical EBFM to fisheries management have been investigated, and considerable attention has been given to developing effective indicators of the present status of and changes in ecosystems and putting them to practical use. Among ecosystem indicators, developing socioeconomic indicators for EBFM is particularly important. This is because socioeconomic factors have direct effects on ecosystems, and ecosystems have direct effects on socioeconomic factors. Therefore, it is imperative that socioeconomic indicators are developed and evaluated in order to predict changes in ecosystems and to provide advice for effective fisheries management. This study is aimed to develop socioeconomic indicators which can be combined with biological and ecological indicators, in order to conduct the ecosystem-based fisheries assessment. In terms of socioeconomic indicators, five socioeconomic criteria were considered as important attributes of socioeconomic changes. These criteria include economical production, business conditions, income, market, and employment indicators. For evaluation of newly developed socioeconomic indicators, the Traffic Light System (TLS) method was used. In addition, on the basis of the application of developed indicators to the Korean large purse seine fishery, the socioeconomic conditions of the fishery and the usefulness of the indicators were evaluated and management implications were discussed.

This study was conducted to understand the quality characteristics of 89 types of commercial salt-fermented fishery products by measuring their physiochemical compositions and biogenic amine contents. All samples had the following measurements; 41.59-89.20 g/100 g of moisture, 1.71-25.70 g/100 g of salinity, 3.21-7.05 of pH, 0.80-2.93 g/100 g of total nitrogen, 87.02-1,296.78 mg/100 g of amino nitrogen, and 7.30-926.34 mg/100 g of volatile basic nitrogen. The physicochemical components differed extensively between samples from different raw materials, including, fish, shellfish, and others. Histamine (0 to 1,072.2 mg/kg), putrescine (0 to 2,536.4 mg/kg), cadaverine (0 to 545.2 mg/kg of cadaverine), tryptamine (0 to 1,287.9 mg/kg), and tyramine (11.3 to 563.3 mg/kg) were the major biogenic amines detected in the samples. These findings suggest that salt-fermented fishery products meet the domestic criteria but have different ingredient compositions and most had high biogenic amine contents. The results suggest that it is necessary to establish criteria for evaluating the quality characteristics using the ingredient composition and biogenic amine contents of commercial salt-fermented fishery products.

This study analyzes the strategy of determining economic development planning on SME improvement in Indonesia. A qualitative approach was conducted through interview questionnaires with twenty respondents, including sixteen Regional Apparatus Work Unit, Fisheries and Marine Office lecturers, subdistrict heads, and development observers. The method used is Analytical Hierarchy Process (AHP). AHP prioritizes criteria and sub-criteria to increase economic growth, reduce poverty, and increase community participation, while indicating the sub-criteria to optimize resource potential, strengthen micro-economy, develop tourism potential, utilize fishery potential and cultivation, and improve institutional performance. The AHP weighting results based on competitiveness and regional development of Bantaeng Regency is the priority in policy-making for a solution. The research shows that the government strategy, based on the perception of the stakeholders, is: optimizing resources strategy with priority to maximize the resource-carrying capacity that includes agriculture and farm, tourism development potential strategy, self-reliance of community groups and coaching and management. Strategies to strengthen micro economy include: industrial control, SMEs, community cooperatives and infrastructure improvements, strategies to improve institutional performance work capacity and work ethic, and strategies to utilize fisheries and cultivation potential technological development, provision of processed industries of fishery products, and improvement of the quality of the environment.

With the restriction of foreigners' entry into Korea due to the COVID-19 pandemic, the fishery industry faced significant challenges in supplying migrant workers. In response to this, there is growing interest in methods that could facilitate the stable employment of migrant workers. This paper investigates whether the current system used for the employment of migrant workers in the fishery industry, which is highly dependent on them, adequately performs its function of providing a stable and skilled workforce amid the intensified labor shortage resulting from decreasing numbers of households with employment in the fishery and the aging Korean fishermen. To this end, past studies and government documents pertaining to the current system were analyzed, and a survey targeting the owners of offshore fishing boats that employ migrant workers was conducted. A total of 147 owners of fishing boats responded to the survey, and the data of 499 migrant workers employed by them were used for the analysis. The analysis indicated that the migrant fishermen had difficulty in acquiring minimum scores for the change of visa status according to the criteria for the Skilled Worker Points System. Furthermore, distinct differences were found between the characteristics and working conditions of migrant workers employed through the Employment Permit System (EPS) and the Foreign Seamen System. Based on this result, this paper suggests the reorganization of the skilled migrant worker system in the fishery industry and the expansion of the regional specialized visa pilot project.

This study analyzed the content of eight biogenic amines (BAs), including histamine, in 198 fishery products (121 school-meal products and 77 distributed products) in Korea in 2019. Changes in BA content according to time, temperature, and salt treatment in Japanese Spanish mackerel, chub mackerel, and salmon were also observed. The average histamine content of 198 fishery products was 0.4±2.3 mg/kg, and all were within histamine criteria (200 mg/kg or less). As a result, the margin of exposure (MOE) was calculated to evaluate the risk of fishery products, and school-meal fishery products were evaluated as safe with a MOE of 1 or more. At 30℃, the histamine content of the fish increased rapidly to 144 mg/kg (Japanese Spanish mackerel, 36 h), and 308 mg/kg (chub mackerel, 24 h). When the Japanese Spanish mackerel, chub mackerel, and salmon were stored at 4℃, histamine was not detected for 3 days, and it was not detected for 14 days at -20℃. The BA content (histamines, etc.) of salt-treated Japanese Spanish mackerel and chub mackerel was lower than that of fish not treated with salt.

The purpose of this study is to find food safety approach in the Eco-label Chain of Custody(CoC) which is only focused to traceability. Because, consumers want to be assured the certified seafood comes from sustainable fishery as well as hygienic. In order to this approach, we used Analytic Hierarchy Process(AHP) method as belows. We first understood the CoC criteria for using pair-wise comparison and analyzed and selected each Eco-label certifications and standards. Second, we carried out a survey to the targeted standard Marine Stewardship Council(MSC) CoC auditors all over the world and analyzed the priorities of food safety approach to 4 principles and 12 criteria belong the MSC CoC Standard. As the results, we found out that 'Management System' has the highest priority in the principles and 'Documentation' and 'Keeping Record' are the most important criteria for this approach. In addition, 'Training' and 'Identification' are also higher priority of criteria. So, we suggested food safety approach method for improvement of these criteria in conclusion based on discussion with specialist in this field.

Many studies to cope with the present problems of Korean coastal and offshore fisheries has been performed, but these were done partly in necessities and general studies for Korean inshore and offshore fisheries are in early stage. Most of these studies adopted analytical way of approach for each fishery individually and they could not reflect the effect of correlated interaction among fisheries on the several common species/stocks, and thus optimal effort allocation was impossible. To consider general fisheries and optimal effort allocation among competing mixed species, a linear programming (LP) approach is applied in this study and introduced into 16 important inshore and offshore fisheries with 13 constraining species which were chosen by annual yield order. This study is not based on the biological interaction among species (i.e., prey - predator system) but the technological interaction between species and fishing efforts. For the application of LP model in these fisheries, the standardization of fishing efforts through different fishing gears could not be successful and a new way of effort standardization through CPUE for vessel tonnage was originated. Total standardized fishing effort on a particular species i, Ei, is computed as the linear summation of standardized fishing effort generated by each fishery j. That is, (equation omitted) where $f_{j}$ is the total vessel tonnage of fishery j and aij is the coefficients contributing to the standardized fishing effort per ton for species i taken in fishery j. The total fishing effort level on species i due to both directed fishing and by - catch can thus be accounted in the aij's. Optimal effort allocation among the j fisheries may be considered a minimizing problem (minimize $\Sigma$ $f_{j}$), subject to the constraints that standardized fishing effort levels on particular species are maintained at, above, and below certain predefined levels. Fishing effort goals for individual species can be based on various biological and/or economic criteria, i.e., fishing effort level generating maximum sustainable yield and/or maximum economic yield. But in this study the $F_{0.1}$ criteria which was accepted as an approximate level for $F_{mey}$ by Outland and Boerema's (1973) study. The findings of this study are, (1) LP model can be applied to the Korean inshore and offshore fisheries giobally. (2) Through a new way of combining multiple different fisheries' efforts for a particular species together generating standardized fishing effort, Schaefer curve could be applied to the complex system successfully. (3) The results of this study for total reduction scale were mostly the same as those of prior studies, but different much from the individual scales of reduction. This study showed the necessities for exploitation of more concrete parameters to put into consideration of profitability of fisheries and social factors, and this model can be modified according to the actual constraints. Also, considering the age structure of stocks, this model can be developed into better one for better fisheries management.ent.

The paper deals with the problem of selective harvesting in a prey-predator model with predator self limitation. Criteria for local stability and global stability for both the exploited and unexploited system are derived. The effort has been considered as a dynamic variable and taxation as a control instrument to protect the fish populations from over exploitation. Finally, the optimal taxation policy is discussed with the help of control theory.
