The purpose of this study is to assess the sanitation level and purchase behavior of fishery products, and to identify management conditions of bad smell from cooking fish at home as perceived by housewives in a metropolitan area. Frequency analysis, descriptive analysis, and cross-tabulation analysis were employed as statistical techniques for current study. Total 270 were collected from housewives. The statistical variables included the kinds of cooking oil and the age of housewives, the types of hoods for fish roasting, the types of covers for fish grills, the number of family, the ventilation methods, and the maintenance of kitchen utensils based on family incomes, and they showed statistically significant differences(p<.05). Furthermore, the housewives whose sanitary cognition level for fishery products was high, the housewives whose level of purchase attitude was relatively high, and the housewives who utilized specialized kitchen utensils demonstrated statistically significant differences(p<.05). It resulted from the assessment of such actual conditions as difference of culinary environment according to the sanitation level of fishery products, the level of purchase attitude, and whether the housewives utilized special kitchen utensils or not. The more efforts were proved from those who had the intentions for improvement of an amenable culinary environment at homes, according to the higher income obtainers, the smaller nuclear family, the younger generation, whether the housewives utilized special kitchen utensils or not, and those who had the higher sanitary cognition level of fishery products. The above results were derived from an individual lifestyle or a dietary lifestyle, but eventually this seems to be related with the propensity and values hierarchy of individuals.

Marine populations are maintained through the processes of spawning, growth, recruitment, natural death and fishing in a marine ecosystem. Based upon each of these processes, a quantitative population dynamic model was developed to estimate damages in fishery production due to accidents in a fishing ground. This model was applied for the abalone culture grounds in Korean waters. Three components of damages were identified in the ecosystem of the abalone culture grounds, namely, physical damages in the substratum of the fishing ground, biological damages in the structure and function of the ecosystem, and damages in fishery production. Considering these three components the processes and durations of damages in fishery production were determined. Because the abalone population is composed of multiple year classes, damages influence all the year classes in the population, when they occur The model developed in this study is: $$y=(n_{\lambda}+1){\times}Y_E\;-\;\sum\limits^{n_\lambda-n_c}_{l=0}\;y_{n_c/i}$$ where, y is the expected damages in fishery production during the period of restoration of the damaged abalony population, $Y_E$ is the annual equilibrium yield, $n_{\lambda}$ is the maximum age in the population, $t_s$ is the year of damage occurrence, $n_c$ is the age at recruitment, and $\sum\limits^{n_\lambda-n_c}_{l=0}\;y\;_{n_c/i}$ is total expected lifetime catch of year classes which were recruited during the restoration period.

The global warming related to GHG (greenhouse gases) emissions from industries is a major issue globally. Furthermore, GHG emissions from the fishery industries also represent an important issue, as indicated by "The Code of Conduct for Responsible Fisheries" at the Cancun, Mexico, meeting in 1992 and by the Kyoto protocol in 2005. Korea pronounced itself to be a voluntary exclusion management country at the 16th IPCC at Cancun, Mexico, in 2010. However, few analyses of GHG emissions from Korean fisheries have been performed. Therefore, a quantitative analysis of GHG emissions from the major Korean fisheries is needed before guidelines for reducing GHG emissions from the fishing industry can be established. The aim of this study was to assess the present GHG emissions from the Korean Purse seine fishery using the LCA (life cycle assessment) method. The system boundary and allocation method were defined for the LCA analysis. The fuel consumption factor of the purse seine fishery was also calculated. The GHG emissions for the edible fish were evaluated by determining the weights of whole fish and gutted fish. Finally, the GHG emissions required to produce 1kg of whole fish and 1kg of edible fish were deduced. The results will help determine the GHG emissions from the fishery. They will also be helpful to stakeholders and the government in understanding the circumstances involved in GHG emissions from the fishing industry.

This paper seeks to find out possibility of introducing market order into Korean fisheries regulatory system. Hayek tells us that market order is equivalent to spontaneous order, while regulations are man-made order created based on incomplete knowledge. He also sees market competition as a discovery procedure of knowledge and information. From this perspective is discussed Korean fisheries regulatory reform-particularly issues of establishing property right on fishery resources. It appears that there is quite a large room for substituting market functions for the regulations regarding fishery resources management, even though fishery resources have a very nature of common pool. Advanced fisheries suggest that successful regulatory reform require a well-prepared strategic plan and check list. In addition, the government should be able to secure sufficient monitoring and surveillance power and to play an important role as a fair supervisor.

This study was investigated the species composition of demersal fishes by a bottom trawler GAYA, in order to be used basic data for resources management of fishery in the jointly controlled waters of the East China sea. We caught 52 species, 1,167 individuals and 186.171kg in biomass in summer, and 1,924 individuals and 200.871kg in biomass in winter The first dominant species in individuals in summer was Glossanodon semifasciatus, and in biomass was Dentex tumifrons. But that in winter was Ovalipes punctatus in both individuals and biomass. It was a special phenomenon that crustacea was to be the first dominant species compared with general offshore fishery in Korea. Catch per unit effort (kg/hr) of bottom trawl in winter was higher than that in summer. There was also big difference by station in the diversity index, the evenness index and the dominant index.

The negative fishery factors from an environmental perspective are greenhouse gas emissions due to high fossil fuel use, destruction of underwater ecosystems by bottom trawls, a reduction in resources by fishing, and damage to ecosystem diversity. In particular, the greenhouse gas emissions from fisheries is an important issue based on the Cancun meeting in Mexico in 1992 and the Kyoto protocol in 2005. However, no investigations on the GHG emissions from Korean fisheries have been conducted. Therefore, a quantitative analysis of GHG emissions from the Korean fishery industry is needed as a first step to identify a method to reduce GHG emissions from fisheries. The purpose of this study was to investigate the degree of GHG emitted from fisheries. Here, we calculated the GHG emissions from four main Korean fisheries(i.e., large trawls, large purse seines, Danish seines, and bottom pair trawls) using the life cycle assessment(LCA) method. The system boundary and input parameters for each process level were defined for LCA analysis. The fuel use coefficient of each fishery was also calculated. The GHG emissions from edible seafood were calculated considering different consuming areas. The results will be helpful to understand GHG emissions from Korean fisheries.

Thousands of demersal fishes inhabit in the waters around Korea and most of them are overexploited. One of 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 Danish seine fishery from 1960s to 2010s. Gross tonnage was decreased stably, but the horse power was increased annually. The length of ground rope, warp and hand rope was somewhat longer, but changed a little. Color fish finder was utilized from the mid-1960s and positioning system was used five years later. A hydraulic line hauler were introduced in the mid-1980s, and supply rate was gradually increased. Surveys on the supply and upgrading of fishing equipment utilized visiting researchers. Therefore, the relative fishing power index in the Danish seine fishery increased stably from 1.0 in 1970 to 1.0 in 1980, to 1.2 in 1990, to 1.3 in 2000 and to 1.3 in 2010. The results are expected to contribute to reasonable fisheries stock management.

The fisheries industry has led the Korean economy, and has been achieving high-level position in the world. However, this industry meets aging, low growth and profit. In order to overcome this critical situation, it is needed to understand the overall status of industry. In industry level, most of previous researches focused on ocean industry rather than fisheries. In addition, scholars have been getting a lot of attention about fisheries cooperatives, fishing-ports, methods of fishery, and manufacturing process in fisheries sector. The aim of this research is analysis of domestic fisheries industry's managerial performance using data envelopment analysis(DEA) considering operating and scale view. Furthermore, the comparative analysis is performed by firm size, and industry type. In results, fisheries industry's managerial performance is not high, overall. In more detail, most of big size firms are under decreasing returns to scale(DRS) status. Fishery processing industry's performance is low, and fishery distribution industry has the best performance. This paper suggests that transferring operating capability from big firms to small firms, and policy supports and firm's activities should be accompanied for high-value added in fisher, and fishery processing industries.

The existing Law of fisheries Management of China was firstly established on October 30th, 1986 and revised in October, 2000. The new Law of Fisheries Management provided a basis for introduction of the TAC (total allowable catch) system into China. Introduction of the TAC system is a natural result of the practise of EEZ (exclusive economic zone). In addition, the inability of the traditional fishery management system and the promising results obtained by conductions of TAC system in some countries with advanced fishery also make the introduction of TAC system a necessity, However, the contradictions between the unrealistic introduction of the fisheries management systems, the small-scale operation, higher expense of the conduction and supervision of the systems, and the insufficiencies of human power, financial fund, and scientific technique of the underdeveloped country resulted in the ineffectiveness of the new systems. So this study is to discuss the background and the possibility of TAC system implementation in china. The results of this study showed that many factors restrict the implementation of TAC system into China at present. It will take a long time to practise the new system. meanwhile, reforming and improving the functions of the existing systems to provide a better environment will play an important role in the introduction of the TAC system into china.
