  • The aims of this study are to examine urgent problems for reorganization into future-proof large purse seine fisheries in order to positively cope with rapidly changing domestic and foreign fisheries circumstances. First, this paper provides current situations of the large purse seine fisheries. The current situations of it are composed of fisheries influence such as vessel number, vessel power, and fisher number, use of resource and fishing places, and changes in products and sales of species caught by the large purse seine. Secondly, this paper reviews current problems of the large purse seine fisheries including cost reduction and increase of value added. Thirdly, this paper suggests basic development direction and countermeasures for strengthening competitiveness of the large purse seine fisheries. In conclusion, urgent problems of the larger purse seine fisheries can be summarized as inefficiency of distribution structures and retarded landing system and facilities as well as the worse of profitability according to shrink of fishing places, reduction of products, lack of workers, and increase in oil price. To solve the urgent problems, the large purse seine fisheries should be changed into an industry with low cost and high efficiency, and also need to introduce of new production system, strengthen autonomous management of natural resource, and increase in value added to products.

  • Changing concepts in fishery science increasingly are recognizing depletion of traditional stocks, utilization of alternate(non-traditional) species, demand for high quality products, and a total resource utilization approach. Innovative practices are occurring in fisheries processing wherein solid and liquid discharges are no longer treated as 'waste,' but rather as valuable feedstocks for recovery of a variety of value-added ('value enhanced') by-products. Among these are protein hydrolysates, soluble proteins and amino acids, proteolytic enzymes, flavor and flavor extracts, pigments, and biopolymers such as chitosan. Properties and applications of this deacetylated derivative of chitin are noted. Crustacean processing by-products are discussed in terms of their serving as materials for generation of natural flavors and flavor extracts, and products such as fish sauces using contemporary enzymatic techniques. Various food and feed applications of fisheries processing by-products are illustrated with increased usage seen in formulated diets for an expanding aquaculture market. Examples are given of aquaculture becoming increasingly significant in global fisheries resource projections. Critical issues in the international seafood industry Include those of seafood quality, processing quality assurance (HACCP), and recognition of the nutritional and health-related properties of fisheries products. A variety of current seafood processing research is discussed, including that of alternate fish species for surimi manufacture and formulation of value-added seafood products from crawfish and blue crab processing operations. Increasing emphasis is being placed on international aspects of global fisheries and the role of aquaculture in such considerations. Coupled with the need for the aquatic food industry to develop innovative seafood products for the 21st century is that of total resource utilization. Contemporary approaches in seafood processing recognize the need to discard the traditional concept of processing 'waste' and adapt a more realistic, and economically sound, approach of usable by-products for food and feed application. For example, in a period of declining natural fishery resources it is no longer feasible to discard fish frames following fillet removal when a significant amount of residual valuable flesh is present that can be readily recovered and properly utilized in a variety of mince-based formulated seafood products.

  • Fish bone-based calcium products are currently receiving much attention among high value-added industries involving calcium. Industrial processing of fish products yields unused fish parts including bones, which could be used as marine health foods to enhance the economic and environmental benefits of fish production. The ultimate goal of this study is to develop the high value-added fisheries products fortified with fish bones supplementing calcium. We here explored the physical and chemical softening methods of the fish bones to enhance texture of the fish products with a high degree of calcium absorption rates. The eluted calcium from the fish bone was quantified with the inductively coupled plasma optical emission spectrometry (ICP-OES). The characteristics of the softened fish bones were determined by the laser diffraction particle size analysis, texture profile analysis, and volatile organic compounds (VOCs) analysis. As the result, the optimized softening method of fish bone was established when Theragra chalcogramma bone was treated twice with the pressurized high temperature (110-120℃ and 1.0-1.5 kg/cm2). The produced softened fish bone turned out to be suitable for the food additives with low particle sizes, low hardness values, and negligible VOCs responsible for the unpleasant flavors.

  • Since the existing mass production and consumption systems are no longer sustainable, countries are pushing for policies to make fisheries by-products as resources in an eco-friendly manner, and international standards are also being strengthened to increase the value of by-products. In Korea, economic and environmental perceptions of the by-products are rapidly changing, such as realizing carbon neutrality and enhancing circular resources by Korean Sustainable Development Goals. Raw materials derived from the by-products have been steadily imported from 2018. In particular, the number of imports of fish collagen peptides was only 16 number of times in 2017, but was rapidly increased to 483 number of times in 2020. Simultaneously, the demand for raw materials and nutrients for health functional food derived from fish by-products, which did not exist statistically until 2017, started to arise from 2018, and in 2019, consumption of high-value-added raw materials for fish by-products increased by 45% compared to the previous year. However, limitations are in legal and biotechnical industry aspects while its value as a biomaterial is recognized in the by-products-related industry. In this study, therefore, the status of by-products for upcycling biomaterials was reported and provided a scientific basis for supporting governmental strategies. In order to fulfill with the principles of a sustainable circular economy, the factors on hinder the marine bio-industrialization of the by-products were derived and suggested directions and plans for development into a high-value added the by-products as the marine bio-industry by substituting imported raw materials to support the development.

  • The study aims to identify the generation and treatment of fishery by-products in Korea and suggests future directions and strategies for their eco-friendly utilization and industrialization. First, the study focuses on the identification of the generation and their treatment in Korea since merely few study were conducted and they did not provide enough information regarding the overall generation and treatment at the national level. According to the estimation, Korea generates 800 thousand to 1,200 thousand tones of fishery by-product every year. The fishery by-products generated at large seafood markets and processing facilities are used or processed as fish meal and feed, but those generated from households and small seafood restaurants are currently treated as food waste. In addition, inadequately treated fishery by-products cause various problems such as spoiling urban landscape, creating odor and incubating pest. After identifying the generation and treatment of fishery by-products, the study suggests directions for the formulation of infrastructure for transition into resource circulation society, minimization of dumped waste and their eco-friendly recycling as resources, diversification of recycled goods and development into a high-value added industry. Finally, the study suggests detailed strategies for the directions such as establishment of legal and institutional foundation, separation of fishery by-products from wastes, development of technology tailored for commercialization, introduction of pilot projects for industrialization and cultivation of social enterprises.

  • The proportions of both the fishery industry and the gross regional domestic product in the national economy are gradually decreasing. If high value-added processed fishery products suitable for regional characteristics are developed, these proportions can be improved. In pursuit of this, it is first necessary to discover processed fishery products specialized in each region and then establish a development framework for them. In this study, location coefficient was used to find processed fishery products specialized in each region. Then, dynamic shift-share analysis was used to establish a development framework which consisted of four development types of processed fishery products. Based on the magnitudes of the industrial mix effect and the regional shift effect, the supporting strategy directions were proposed for four development types of processed fishery products. The supporting strategy directions were all focused on revitalizing the local economy.

  • By-products from fisheries produced in Korea are of the same industrial material as imported raw materials and are valuable resources for marine bioindustries. Securing raw materials for the mass production of functional materials is one of the main objectives for marine bioindustrial development. The use of fishery by-products as raw materials is anticipated to increase rapidly as the biomarket is growing into a promising industry. In this study, data were acquired from an open-source environment to perform exploratory data analysis, and various visualization methods were used to compare fishery production to the production of marine processed products in the year 2020. This study suggested that the amount of seafood processing, types of processing items, and areas where fishery processing residue is generated, should be able to secure hygienic raw material supply in large quantities. Thus far, it has been found that the Gyeonggi-do and Busan province, where HACCP-certified processing facilities are concentrated, and the local government Seafood Cluster and the Smart Aquaculture Cluster are at the forefront of stable, mass production of raw materials.

  • The market size of Korea's seafood industry is estimated to be about 62 trillion won ('19), of which the seafood processing industry is about 10 trillion won ('19), accounting for approximately 16% of the total market size. However, the current level of processing technology required for the development of seafood products is mainly simple primary processing, such as freezing and drying raw materials (in Jeollanam-do, which ranks first in the country in terms of seafood production, primary processors account for 86% of all seafood processors).In the future, trends in the development of processing technology for seafood will become more advanced in response to changes in domestic and international food consumption patterns. Blue food tech linked to ESG, convergence and digitalization linked to the 4th industry revolution will be further advanced in line with the national seafood industry policy direction. Through this, it is expected to establish itself as an axis of future technology management in the fisheries sector based on the large and small success stories of accumulated seafood R&D commercialization.

  • The global cod market is supposed to have weak structure with a high dependence on the supply of Russia, the United States, Norway, and China. The COVID-19 pandemic has significantly disrupted the cod supply chain for the worse. Fish processing facilities in China stopped their operation, and cod demand declined due to shrinking consumption in Europe. The position of South Korea as an intermediary trade country between Russia and China strengthened due to the U.S.-China trade war and the Atlantic cod decrease in 2019. However, this global cod supply chain collapse has caused South Korea to export accumulated cod to Indonesia and Vietnam at a bargain price, showing that South Korea was unable to cope with this supply chain crisis. The primary purpose of this study is to investigate changes in the global cod supply chain and their impacts on the intermediary trade of South Korea caused by the COVID-19 pandemic. It also aims to provide implications by analyzing advanced cases in Denmark. As the cod supply chain crisis countermeasures, this study suggests that South Korea develop high value-added marine products, gain competitive advantages by solidifying the value chains of related countries, and activate export by discovering alternative markets in terms of the supply chain of the cod industry.
