A stable protein source is required to support the rapidly increasing global population, and fishery products are a particularly important part of the required protein supply. However, due to continued overfishing, fishery resources are depleted, and the number of fish caught by fishing boats has stagnated. Consequently, the aquaculture industry is becoming increasingly important. Internationally, smart aquaculture technology that minimizes labor and environmental pollution has been established through technological developments supported by large investments in automation and water treatment technology over the last several decades. In the case of Korea, the aquaculture industry has not yet emerged as a labor-intensive primary industry. However, in recent years various attempts have been made to apply ICT technology to aquaculture to overcome these problems. In this study, domestic and foreign technologies and patent trends for smart aquaculture are analyzed. In addition, the current status of the smart aquaculture cluster business that the Ministry of Oceans and Fisheries has been promoting since 2019 to utilize ICT technology in aquaculture is introduced.

Climate change due to global warming is affecting the global environment. The fishery industry is highly dependent on the natural environment, so the fishery industry is increasingly volatile due to the rapidly changing climate change. At the same time, consumers' anxiety due to marine pollution such as microplastics, radioactivity, and heavy metals are increasing. Accordingly, cell-based seafood are being proposed as an alternative for the sustainable use of seafood resources. Cell-based seafood manufactured through a process of differentiation and proliferation using cells isolated from actual seafood and cell, scaffold, media, and bioreactor technologies are organically connected to each other. This review summarizes the latest research status of cell-based seafood. Based on this, suggests a development direction for cell-based seafood to properly settle in the future market.

This study is to focus on the status of implementation of bilateral-fishery order based on the Korea-China fisheries agreement and aims to improve fisheries relationship between two countries. Korea-China Fisheries Agreement entered into force in 2001, and serves as a basic framework of the bilateral fisheries order. However, the fishing order between Korea and China has the following limitations. First, it is standstill of joint response for a practical resource management. Second, there are still gaps between the quotas of mutual accord fishing and fishing operation work performance. Third, China's illegal fishing is taking place consistently. Fourth, the effective cooperation between two countries in fisheries is not carried out. Finally, the Korea has faced difficult situations to adhere to a balanced position in the fishery negotiations due to conflicting positions on China and Japan. In order to solve these problems, the fishing order between Korea and China will be able to maintain the competitiveness of Korean fishery sector by reinforcing Korea's fishing sovereignty, Korea and China, based on trust and cooperation, will make efforts to improve bilateral fisheries relations to maximize mutual benefit in fishery sector. Specifically, first, the two countries should strengthen the resources management based on the scientific research and the improvement of imbalance of the mutual agreed fishing in EEZ. Second, Korea has to achieve our targeted performance of fishing operation and establish a joint resources management system between two countries in the provisional measure zone. Third, Korea should implement to collect fisheries information about China fishing vessels which are operating in the EEZ of Korea. Finally, Korea and China should be building up effective governance framework for the establishment of fishing order.

Changes in ecosystem risks were evaluated using the ecosystem-based fisheries assessment (EBFA) approach of Zhang et al. (2009, 2010) and the comprehensive ecosystem-based fisheries management (EBFM) plan was made for the southern sea of Korea in this study. The risk assessment of the southern sea ecosystem was conducted by establishing ecosystem management objectives and by estimating risk scores (RS) for indicators. To conduct this analysis a number of indicators and their reference points for assessing these risk scores were developed in this study. The number of indicators in the risk analysis was 28 for the quantitative tier 1 analysis and 30 for the qualitative tier 2 analysis. The objective risk index (ORI), species risk index (SRI) and fisheries risk index (FRI) were calculated from the risk scores. Comparing the past (1988) and the current (2008) status of fisheries resources, management implications were discussed. The fishery risk index (FRI) of large purse seine fishery in the southern sea of Korea decreased substantially from 0.972 in 1988 to 0.883 in 2008, and improvement in the management of fisheries operated in the southern sea of Korea.

Seafood is attracting attention as a future food industry. In recent years, the demand for fishery equipment of mechanization, automation, and unmanned was increased due to the environment affected by seafood processing, stricter regulations on safety, decline and aging of fishery worker. Ark shell (Scapharca subcrenata) was being produced in many steps in the production process. The process has been made such as collection-landing-washing-first sort (goods/non-goods)-transports-second sort (size). It was undergone first and second steps by delivering to the consumer. Here, the first step is to sort goods to collection and the second step is to sort by size. The fishery workers need ten people in first step and six people in second step. The workload of one hour per kg is 4,247 kg/h in first step and 2,213 kg/h in second step. In addition, the goods ratio by work process was 79% in first step and 98% in the second step. In this process, a lot of fishery worker and working time is needed. Therefore, this study developed elemental techniques for an automated size sorting system considering the working process problem, time and situation for washing and sorting of ark shell.

This study was carried out to investigate the benthic polychaetous community and benthic ecosystem quality status on the adjacent continental shelf of Jeju Island, and field surveys were conducted at 31 stations in July and August, 2020. The surface sediment was generally composed of muddy sand facies and sandy mud facies, and the average particle size was medium silt (6.1±1.6∅). The benthic polychaetous community revealed a total of 73 species with a mean density of 242 ind./m². The major dominant species were Notomastus latericeus, Ampharete arctica and Onuphis shirikishinaiensis. By the cluster analysis and nMDS results based on species composition of the benthic polychaetous community, the study area was divided into three station groups arranged from east to west by the water depth and sedimentary facies. The station group located in the west was subdivided into two station groups from south to north. From results of correlation analysis and PCA, it was found that the benthic polychaetous community in the study area had a strong correlation with the sedimentary environment and water depth. The benthic faunal community (or ecosystem) on the adjacent continental shelf of Jeju Island was assessed to be in a healthy state by biotic indices such as AMBI and BPI.

본 연구는 최근 3년간의 항만 및 어항개발사업에 따른 해역이용협의서 91건을 분석하여 그 작성실태(평가항목별 조사현황과 영향예측 등)를 파악하고, 문제점을 개선하기 위한 방안을 요약 제시하였다. 9개 평가항목 중에서 해양화학, 해양퇴적물 및 해양생태계 부분에서는 현장조사 비율이 높았으나(70 % 이상), 조사자료를 활용한 영향예측은 미흡하였다. 반면, 해양물리의 경우는 현황조사 비율은 낮았지만(조석 7.7 %, 조류 24.2 %), 영향예측 수행비율은 높아 예측결과를 뒷받침할 만한 근거와 검증 측면에서 문제점이 있었다. 즉, 조사와 예측에 대한 평가가 연관성이 낮아 신뢰성이 떨어지고 있었다. 항만 및 어항개발사업에 있어 영향예측과 밀접하게 관련되어 있는 주요 외력(조석, 조류 및 파랑 등) 및 중점평가사항에 대한 체계적인 진단이 필요하나, 현재는 사업유형을 고려하지 않는 일반적인 평가방법과 자료인용이 이루어지고 있는데, 향후 사업규모와 지역특성 등을 고려한 중점평가항목과 구체적 평가사항(조사시기, 정점선정)을 사전에 스코핑해 줄 수 있는 제도적 장치가 필요할 것이다. 또한, 현장조사자료의 신뢰성 강화를 위해 해양화학 및 해양퇴적물의 분석에 관한 정도관리체계의 적용이 강화되어야 할 것이다.

Parabrachiella bera (Yamaguti, 1939) is redescribed based on newly collected material from multicolorfin rainbowfish, Parajulis poecilopterus, landed at Wando fishery port on the southern coast of Korea. Although some differences were observed between the original description and the specimens examined in this study, these differences do not warrant a change in the taxonomic status of this species. Parabrachiella bera bears some resemblance to Parabrachiella incurva Shiino, 1956, but differs from it in details of the trunk and genital processes.
