This study is an analysis of the Aquaculture Industry Development Act that has recently been passed by the National Assembly. In order to improve the structural problem of Korea's aquaculture, a large revision of aquaculture related laws and regulations is needed. The enactment of Aquaculture Industry Development Act is necessary to that effect. It is adequate to aim for development as aquaculture industry not as aquaculture, to alleviate entry restriction of aquaculture, and to provision diverse promotion and support policies. However, it is a concern whether the current Aquaculture Industry Development Act can achieve its goal of enhancing the competitiveness of aquaculture and sustainability. Rather than to solve the problem, the act holds the possibility of further fixing or exacerbating the problem. So there is concern for side-effects after the enactment. This is due to the fact that it complicates terminologies by unnecessarily differentiating aquaculture related concepts from the existing Fisheries Act, lacks regulations regarding voluntary participation in aquaculture, and has limited methods to alleviate entry restriction. In addition, there are very few measures for the scale improvement of aquaculture along with the unlikeliness of a significant effect of the review and evaluation for re-licensing. Thus, the Aquaculture Industry Development Act should promptly be revised after its enactment.

Aquaculture drugs have used to prevent disease in aquaculture field for many years. In spite of many advantages, overdose and abuse may cause environmental pollutions and antibiotic resistances. Many countries try to protect the environment, biospecies and food safety. Recently, Korea enact laws and ordinances such as the Aquatic Animal Disease Control Act. The purpose of this act to contribute to the stable production and control system for aquatic diseases. The Maximum residue limits (MRLs) of aquaculture drugs have been established by Ministry of Food and Drug Safety (MFDS) and Drug licensing was in National Fisheries Research and Development Institute (NFRDI) by Aquatic Animal Disease Control Act. There is 750 items in aquaculture drugs and these are classified into 4 group, which is approval, necessary for prescription, unregulated and safety drug, and banned drug. MRLs of 30 items in aquaculture drug have been established by Food Sanitation Act. Future research is required to determine the suitable for abundant varied fishes of drugs for side effects and safety.

The objects of this study are to consider the current features and the development process of the utilizing system of aquaculture farms in Japan, and to suggest the theoretical basis for improvement of aquaculture system of Korea in the future through the analysis of background of the liberalization theory proposed recently. The aquaculture-fishery system of Japan was begun from the Meiji Era Fishery Act and New Fishery Act of the World war II. A small sum of fishery fee is paid to the fishery cooperative having fishing rights for securing fishing area newly, because the aquaculture of Japan belong to fishery cooperative not individual ownership of union membr of cooperative society, the other words, cultivation fisheries household. In case of Korea, there are several differences with Japan as follows; almost cultivation fisheries household has a individual license, the lisence of fishing rights are recognized as an article, the license of fishing lights are able to do sale. Therefore, it is needed to paid a lots of money for securing fishing area newly. On the other hand, advanced countries in the marine aquaculture such as Norway have reached the stage where the managing abilities of marine aquaculture are similar to those in the manufacturing industry. And the number of large scale aquaculture farms with developed technologies and advanced marketing strategies in those countries is increasing. Considering that the marine aquaculture in Japan under the similar fishery systems of Korea has developed the state-of-the-art management skills or lead to large scale management, it is difficult to expect the decrease in the production costs under the small scale family business in Korea and this will lead to the decreasing competitive advantage over the imported seafood. Therefore marine aquaculture in Korea needs to increase the economy of scale to acquire the competitive advantage.

This study examines the significance and problems of the Fourth Amendment to the Fisheries Act, which went into effect in January 2023. Following the passage of the Aquaculture Industry Development Act, the fourth amendment to the Fisheries Act sought to reform the fisheries legislative framework, while also including significant changes. In particular, a number of new systems for managing fishing gear have been implemented, and local governments now have some autonomy in fisheries management, which has allowed for adjustments to be made to meet the needs of the fishing industry and changes in socioeconomic situations. However, as independent legislation for each fisheries sector continues, the subject of regulation under the Fisheries Act, as well as the Act's position as a basic legal system, has been continuously reduced, overshadowing the Act's objective. As a result, a full-fledged assessment of changing the legislation's name in the future is required, as well as addressing issues such as the lack of difference in the legislative purpose clause and the necessity for further revision of the definition clause. Therefore, any future revisions to the Fisheries Act should aim to overhaul the existing framework, including fishing licenses and permits.

Despite a variety of development in fish farming during the last decades, fish diseases by bacteria, virus, and parasites are still major problems in aquaculture. Aquaculture of Hounder fish is widely performed around Korea as well as Jeju island, due to relatively stable seed production, short farming period, and a higher value in market. However, intensive feeding and environmental pollution in aquacutural farm act as a great limiting factor in economic aspect. (omitted)

We characterized the cytoskeletal beta-actin (${\beta}$-ACT) gene (actb) and its 5'-upstream regulatory region in the Javanese ricefish Oryzias javanicus. The gene and protein structures were deduced from amino acid sequences of the actb gene and conserved in the teleost lineage. The O. javanicus actb gene has common transcription factor binding motifs in its regulatory region found in teleostean orthologues. Following quantitative reverse transcription-PCR, actb gene transcripts were detected in all tissues examined; however, the basal expression levels were different. During early development, O. javanicus actb mRNA levels showed a gradual increase and peaked between late somitogenesis and the heartbeat stage. Microinjection of O. javanicus embryos with the actb gene promoter-driven red fluorescent protein (RFP) gene reporter vector showed a ubiquitous distribution of RFP signals, although most exhibited a mosaic pattern of transgene expression. A small number of microinjected embryos displayed a wide distribution of RFP signals over their entire body, which resembled the expression pattern of endogenous actb. Data from this study provide a basis to develop a transgenic system with ubiquitous expression of foreign genes in O. javanicus.

Flounder was selected as one of the 10 strategic export aquaculture products for seafood export expansion in 2013. The flounder aquaculture industry has promoted export market diversification and product diversification from live to processed goods as a it's main strategy. The purpose of this study is to find an improvement plan for export expansion to the United States, as it emerged as a new target export market for the flounder. A summary of the key findings is as follows. First, the western region of the United States prefers to consume live and fresh flounder, whereas the eastern region prefers to consume fresh flounder. Second, because of it's high quality, Korean flounder is favored in the western region of the United States despite it's high price, whereas in the eastern region of the United States, where production volume is high, Korean flounder has to compete with US flounders because of it's high price. Third, according to the survey results, US consumers tend to enjoy seafood, as well as flounder cuisines. Fourth, the main consumption place of flounders by US consumers are restaurants, and they prefer to consume them in the form of sashimi and sushi. Fifth, 70% of US consumers expressed willingness to consume flounder when eating out. which shows great market potential. However, the high price of Korean flounder and limited size of the live fish market act as major obstacles to expanding export volume. To expand exporting Korean flounder, continuos efforts such as price reduction, exporting highly fresh fish, the co-development of processed food with the US are needed.

This study was performed to have an effect on control the growth of algae such as "Actinastrum fluviatile" which occurs frequently in the aquaculture tank using by a cold plasma, and it also would be expected to promote the growth of water plants due to active element causing OH radicals in the water. In addition, it was verified on the death rate as 99.9% on the scale protrusion of "Aeromonas hydrophila" as well as E. coli, especially, under extreme conditions more than 100 million pathogenic bacterium in the aqua pet tank, the ornamental fish had to act in a safe and healthy environment at over 98% death rate within 48 hours. It has been proven to give no affect on aerobic bacteria that exist in the filter or soil because there was no residual toxicity in the water tank. As the results, it will help to develop and apply on the sterilization device in other industries as well as aquarium organisms due to adopted energy-saving algorithm and reliability in use.
