Agro-fishing villages of agriculture and fishery are suffering deepening gap with urban areas due to depreciation from their products market opening pressure. They are facing problems of decreasing and aging population, poor settlement environment, etc. and losing their vitality for their low productivity and lack of young labor force. These issues of agro-fishing villages of agriculture and fishery are divided in so various items and classes that it is plausible to approach in a way to connect each issue in a small frame of each by selecting sub topics according to each item and each class rather than to solve the issues in a large frame. Chungchungnam-do is approaching the issues through 3 agro innovations(agro fishery, agro fishing villages, agro fishing people) in local government level and Durae enterprises are solving local problems through the self supporting residents' community business by utilizing local resources. This study is to draw clues and solutions to vitalize agro fishery villages through community businesses by detailed reviews and research on cases of Durae enterprises' characteristics and their vitalizations and provide a new alternative plan to agro fishery villages losing their vitality and demolishing their communities.

This study, conducted during 2018-2021 in Gangseo, Seoul, monitored residual pesticides in 14 types of fresh-cut produce, including lettuce, tomato, and celery, in wholesale market and supermarkets. A total of 589 cases (2.9%) were inspected; 17 cases (2.9%) were detected within the criteria, and 2 cases (0.3%) exceeded the maximum residual limit (MRL). When assessing the distribution stage of the pesticide violation, there were two violations in the wholesale market (before distribution), which differed from the supermarkets (during distribution). The detected pesticides, mainly insecticides and fungicides, appeared in the order of flubendiamide, flufenoxuron, and diazinon. A violation rate of 0.3% was found for wholesale market, which is collection area dedicated to fresh-cut produce, and this was lower than that for general agricultural products (1.4-2.5%). Since fresh-cut produce are consumed immediately after simple processing, residual pesticides significantly affect the human body; therefore, continuous monitoring of pesticide residues is required.

This paper aims to examine the local changes in which the introduction of new fishery technology in small remote island, Geomun-Do, had resulted. The main findings are as follows. With the help of introduction of new fishery technology, local fishery industry transformed self-sufficient one into commercial one. This led to increase in the productivity of fishery industry and, subsequently, the emergence of new social system and processing facilities. The growth of fisheries, which led the opening of fishing market and the development of processing industry, made it change local industrial structure. This paper focused particularly on local cultural transformation revealed in the process of the introduction of new fishery technology. In conclusion, the paper argues that the pace of cultural transformation can be selectively appeared by the qualitative characteristics of locality and social group, when new cultural elements are introduced and adapted to a certain locality.

It's about time we had to think an alternative to recover out insufficient fishery market caused by IMF locally as well as the fishery agreement on Japan and China. The Ministry of Maritime Affairs ＆ Fisheries have planning the advancing fishery information integrated system for the fishing present condition, marine resource administration and applicability consideration. The fishery information communication system is build up to the raw data ＆ process-network-content. The communication system must be small size, low cost and adapted SSB transceiver, that is using fishery shipping. In this paper We present digital data communication network to exchange information for fishery and safety between fishing ship and coast station in cheeper communication fee using SSB(single Side Band) in HF(High Frequency) band.

During the past 100 years, Korean fisheries management policies have enforced the license system, it is the most typical regulation system in Korean fisheries. Even now, it has caused resource management failure, it has also invited economic inefficiency and inequity. Accordingly, the Korean government has recently introduced the self-regulatory management system for fishermen with the TAC system. These systems are one of the most market-oriented regulation systems in fisheries management systems. It is defined as regulatory policy tools other than regulations with command and control approach. It is also called “alternatives” which is composed of regulatory alternatives and non-regulatory alternatives. The self-regulatory management system and the ITQ system are cooperative-based co-management between government and fishermen as an alternative management strategy ; it is gaining the increasing attention to improve the effectiveness of fisheries management in Korea. It is expected not only to positively improve function in fisheries regulation, but also to decrease inefficiency in fisheries policies. However, these systems have many problems. The monopolization of rent is one of the typical examples. As solutions for the problem in the aspect of fishery management, fisheries policy is need of approach to industrial organization. For instance, Contestable market theory is one of the good theoretical background, it mean that market is able to free entry and free exit. Thus, fisheries management carry out policies such as revitalization of the used market of capital goods in fisheries, organize of the self-regulatory management group. Conclusively, as the exploiters and managers, fishers and the government should put emphasis on improving economic efficiency so that fishery would grow as an industry that contributes to the increase of social welfare, and the change to that direction will be the only way for our fisheries to preserve its importance.

This paper tries to apply the asymmetrical price transmission(APT) behavior observed in the agricultural industry to supply chains of the domestic fishery industry by a statistical manner. The fore mentioned asymmetrical price transmission refers to when price movements in the later stage of the supply chain do not move in a normal or symmetrical manner corresponding to price movements in the earlier stage of the supply chain. Therefore, when the earlier stage price increase and the later stage price increases to a larger degree, it is called positive(+) asymmetry and the opposite behavior is called negative(-) asymmetry. The study examines the data from domestic producers of three fresh fish types, hairtail, mackerel, and cuttlefish, and tries to examine the price asymmetry between the producer or farm, wholesaler, and retail prices via an APT test utilizing unit root, cointegration, and error correction model. The study found, hairtail wholesale and retail pricing bas a negative asymmetric relationship while mackerel has a negative asymmetric pricing relationship at the producer and retail levels of the supply chain. In the case of cuttlefish, all levels of the supply chain showed negative asymmetrical behavior in the supply chain price transmission, meaning the earlier stage price changes are more rapidly and greatly inputted in the later stage of the supply chain pricing. We believe that the reason why the analysis results show negative price asymmetry is due to the uniqueness of fishery products having an important variable such as freshness. If price increases are greater and quicker than price decreases, then consumer demand, which is sensitive to price increases will decrease and subsequently result in the increase of inventory levels, reducing profits for retailers. Also, frozen hairtail, mackerel, and cuttlefish will act as substitute goods to fresh fishery products. Therefore, fresh fishery products have a high demand of price elasticity. When prices increase, demand quickly decreases. Therefore the profit of wholesalers and retailers to decrease, I think this is the main reason of APT in the supply chain of Korea' s fisheries industry.

This study aims to investigate protein consumption market trends in Korea. Protein consumption was divided according to the protein source into meat, fishery, and plant-based protein. To accomplish the goal of this study, food purchase data from 525 households panels collected by the Rural Development Administration over the last 10 years were used. The results of the study showed an increase or decrease in protein consumption by protein type over the last 10 years, and a reason to explain this change has been suggested. Specifically, this study found a dramatic increase in the consumption of several proteins, including beef sirloin, beef tenderloin, seasoned beef & steak, pork belly, pork shoulder, pork neck, seasoned pork, pork cutlet, sweet and sour pork, canned ham, chicken drumstick, chicken breast, dak gangjeong, Chinese fried chili chicken, salmon, eel, abalone, squid, octopus, webfoot octopus, octopus minor, canned whelk, tofu, cold bean soup,and plant-based milk. Some items showed no increase in consumption (such as beef jerky, pork rib, sausage, bacon, whole raw chicken, cutlass fish, oyster, fish cake, crab stick, surimi sausage,and canned fishery), whereas a few items showed decreased consumption (e.g., mackerel, pollack, cod,and canned tuna)

This paper presents the GJR GARCH model (Glosten et. al, 1993) to analyze the influences of volume volatilities on price volatilities in the fishery market. For the analysis, this study used the monthly price and volume data of aquacultural flatfish in Jeju. As a result, empirical analysis suggested volatility clustering. The persistency parameter(${\lambda}$) was estimated to be approximately 1 in aquacultural flatfish. The results showed that there is a significant negative relationship between the conditional variance of supply and that of price for aquacultural flatfish. This means that the general law of supply is valid. Finally, the empirical analysis was that an asymmetric coefficient (${\gamma}$) of GJR GARCH model was negative (-). This means that the higher volatility of volume leads to lower price volatility. That is, it is useful to make government policies that can adjust the volume (stockpiling, stabilizing supply and demand).

This study was practiced to investigate characteristics and antibiotics susceptibility to 296 isolates of Escherichia coli isolated from 2429 fishery samples sold in Noryangjin Fishery Market from Sep. 2001 to Aug. 2002 It showed 12.2% average E. coli isolation rates for the tested samples. Isolation rates were high in summer, especially July and August, but there was no isolate in winter season. Of the fishery groups, the isolation rate showed in crustacea(15.6%), in mollusca(14.4%), in shellfish(12.0%) and in fish(11.0%). But, differences between the fishery groups was not large. In the case of shellfish, the isolation rate of shucked shellfish (16.3%) was higher than the non-shucked shellfish (6.8%). Following the provinces of origin of the fishery samples, in Gyung-Nam (14.3%) showed the highest isolation rate, whereas Je-Ju (6.9%) showed the lowest isolation rate. Results in 12 kinds of antibiotics susceptibility test, the 169 isolates(57.1%) had antibiotics resistances at least one kind of antibiotics and the 104 isolates (35.1%) had the multiple resistance at least two kinds.
