The genus Semisulcospira is an economically and ecologically valuable freshwater resource. Among the species, Semisulcospira coreana , Semisulcospira forticosta and Semisulcospira tegulata are endemic to the Korean peninsula and Semisulcospira gottschei is widespread in Asia. Therefore, maintenance and conservation of wild populations of these snails are important. We investigat-ed the genetic diversity and population structure of Semisulcospira based on the mitochondrial cytochrome c oxidase subunit I (COI), NADH dehydrogenase subunit 4 (ND4), and combined mitochondrial DNA (COI + ND4) sequences. All four species and various genetic makers showed a high level of haplotype diversity and a low level of nucleotide diversity. In addition, Fu’s F s and Tajima’s D neutrality tests were performed to assess the variation in size among populations. Neutrality tests of the four species yielded negative Fu’s F s and Tajima’s D values, except for populations with one haplotype. The minimum spanning network indicated a common haplotype for populations of S. coreana , S. tegulata and S. gottschei , whereas S. forticosta had a rare haplotype. Also, genetic differences and gene flows between populations were assessed by analysis of molecular variance and using the pairwise fixation index. Our findings provided insight into the degree of preservation of the species’ genetic diversity and could be utilized to enhance the management of endemic species.

Longline fishery targeting tunas and tuna-like species is known to produce a significant amount of catch not only for the target species, but also for ecologically related species like sharks, marine turtles, sea birds and marine mammals. Recognizing this seriousness, tuna related regional fisheries management organizations (t-RFMOs) have established conservation and management measures (CMMs) to reduce bycatch and/or interaction with ecosystem vulnerable species including sea turtles and are obliged to implement bycatch mitigation measures and guidelines on safe release to their member countries. Along with development and strengthening of those measures, various case studies have been conducting to verify the effectiveness of bycatch mitigation for ecologically related species. This study examines the background and progress on developing CMMs of t-RFMOs and regulation programs of the United States related to sea turtles, which have recently become one of the main issues, and reviews case studies on sea turtle bycatch mitigation measures to find out the effectiveness of reducing bycatch rate and impacts to the fisheries. In order to respond the consultation process on certification determination with the United States, it was confirmed the current status of implementation on related measures conducted by Korean tuna longline fishery based on scientific observer data and survey for captains. Even though all Korean tuna longline fleets belong to the deep-set longline fishery (100–300 m), which is not subject to the obligation of those mitigation measures, they are voluntarily implementing both measures, use of circle hook and whole finfish bait, regardless of which RFMO’s Convention area they operate. And the national regulatory and management programs for sea turtle bycatch prevention adopted by Republic of Korea seems to be comparable in effectiveness to that of the United Stated. However, Korea needs to take preemptive measures in establishing sustainable fisheries, including the protection of the marine ecosystem and environment, as stronger requests are anticipated to be made by the international community on this matter.

Shellfish are exoskeleton-bearing aquatic invertebrates that consume various organic and inorganic substances floating in sea-water through filter feeding. Heavy metals are known as absorbed and accumulated in seawater. Some of the toxic heavy metals are highly accumulated in seawater, and exposure to them can cause a variety of risks to the human body. Since Koreans like to eat seafood, they are more likely to be exposed to contaminated seafood with heavy metals. In this study, nine types of heavy metals were analyzed on ten different shellfish species in the coastal area of South Korea. The risk assessment was also done on shellfish in which heavy metals were detected. Zinc (Zn) and copper (Cu) were identified at an average of 56.7 mg/kg (6.70 to 466 mg/kg) and 13.2 mg/kg (0.064 to 143 mg/kg), respectively. Lead (Pb) average of 0.208 mg/kg (0.000750 to 1.02 mg/kg), cadmium (Cd) average of 0.454 mg/kg (0.0388 to 1.56 mg/ kg) and mercury (Hg) average of 0.0266 mg/kg (0.00548 to 0.174 mg/ kg) were identified. Additionally, arsenic (As), chromium (Cr), nickel (Ni), and silver (Ag) were also identified as average concentrations of 4.02 (0.460 to 15.0 mg/kg), 0.167 (< limit of quantification [LOQ] to 0.820 mg/kg), 0.281 (< LOQ to 1.46 mg/kg), and 0.158 mg/kg (< LOQ to 1.15 mg/kg). The result indicates that the monitoring results of heavy metals in most shellfish satisfied the Korean standard. However, Pb and Cd have exceeded some foreign standards, such as the United States and the EU. The permissible human exposure calculated using the heavy metal intake and detection amount was lower than the Joint FAO/WHO Expert Committee on Food Additives human safety standard, and the risk of heavy metals from shellfish consumption was at an acceptable level.

A spotted scat, Scatophagus argus , has a high nutritional value and is among Asia’s most widely consumed fish species. Thua Thien Hue’s consumption market considers this species to be of high economic value and requires protection and conservation of the population. However, the studies on the identification and genetic diversity of S. argus distributed in Vietnam are still lack-ing. Therefore, mitochondrial cytochrome c oxidase subunit I (COI) gene was utilized to distinguish different populations and investigate the genetic diversity of two populations of S. argus from Tam Giang lagoon, Thua Thien Hue province (n = 31) and Ca Mau province (n = 14). The sequencing results indicated 13 distinct haplotypes among 45 sequences. Five single nucleotide polymorphisms were observed to distinguish Hue spotted scat population. The S. argus population in Ca Mau province was higher haplotype diversity (Hd) and nucleotide diversity (π) than those of Thua Thien Hue province, which demonstrates that there are minor differences between haplotypes. There were genetic distances ranging from 0%–4% within the populations and 6.67% between the two populations. In addition to the sequencing, the comparison of morphology, biology, culture, and the growth rate was sufficient to distinguish the spotted scat S. argus in Thua Thien Hue from Ca Mau.

The study carried out a 15-day feeding trial of the fleshy shrimp broodstock that have just finished their first spawn using five different maturation feed types (three types of manufactured feed, fresh feed, and commercial feed) to induce multiple spawning in the shrimp and then analyzed and compared hemolymph levels of total protein, total lipid, hemocyanin, glucose, and cholesterol as well as ovary histology between the treatments to identify the potential of the experimental diets to be utilized as maturation feed. The study found that the manufactured diets of polychaetes + clam and polychaetes + clam + squid resulted in significantly higher levels of lipid and protein in shrimp hemolymph suggesting an indicator of multiple spawning in the fleshy shrimp. The other manufactured diet of polychaets + squid led to the highest 2nd spawning with significantly lower levels of lipid, protein, and cholesterol in shrimp hemolymph. The fresh feed treatment showed similar hematological as well as histological responses to the manufactured diet of polychaetes + squid, but with a significantly lower spawning volume compared to the other treatments. The study demonstrated that the manufactured diets could replace fresh feed as maturation feed and attain a higher shrimp maturation than the commercial feed.

The National Institute of Fisheries Science (NIFS) is the only comprehensive national research institute in the field of fisheries in Korea, which has contributed to the development of all Korean fishery industries (NIFS, 2019). Although the NIFS was officially established alongside the Korean government in 1949, it has over 100 years of research history since the beginning of modern and contemporary fisheries science in 1921 (NFRDI, 2001; Won & Kim, 2021). The NIFS is responsible for developing and disseminating technologies necessary for fisheries and supporting fishery policies through a wide range of research. For effective implementation of these responsibilities, the NIFS has established four major strategic directions: technology innovation for the future of fisheries, achievement of a sustainable fisheries industry, development of technologies for responding to fisheries issues, and strengthening of internationalization and industrialization capabilities. These directions show that the NIFS aims to improve the quality of life through ‘research and solution development,’ rather than by exclusively supplying science and technology knowledge through pure research and development. I would like to introduce achievements toward these strategic directions by the NIFS in 2021. The first achievement is related to strengthening sustainable fishery resource ecology and artificial intelligence (AI)-based marine information prediction. The behavioral characteristics of major species in the East Sea of Korea (cod, walleye pollock, and giant Pacific octopus) were investigated using advanced remote technology for the first time. Korea secured 110 tons of Antarctic toothfish through an approved scientific research survey by a regional fisheries management organization. The NIFS responds to damage from marine disasters by establishing a water temperature prediction system based on AI techniques. The second achievement by the NIFS is the development of new aquaculture breeding technologies, with the aim of producing convenience foods. The NIFS restored the endangered dragon kelp, built a foundation for industrialization, and developed and distributed training techniques for breeding giant grouper, a value-added aquaculture variety that can endure high water temperatures. The NIFS developed and commercialized red sea bream and rockfish meal kits and soft abalone retorts, which removed the fishy smell. The NIFS also developed skin cosmetics using Lactobacillus obtained from the vicinity of Dokdo island. The third achievement for NIFS is focused on environmental management to ensure safety of aquatic products and the development of aquatic accident prediction technology. In this
国立水产科学研究院(NIFS, 2019)是韩国唯一的水产领域综合性国家研究机构，为韩国所有渔业产业的发展做出了贡献。虽然1949年与韩国政府一起正式成立了NIFS，但自1921年开始现当代渔业科学以来，它已有100多年的研究历史(NFRDI, 2001;Won & Kim, 2021)。国家渔业研究所负责开发和传播渔业所需的技术，并通过广泛的研究支持渔业政策。为了有效履行这些职责，NIFS确立了四个主要战略方向:面向渔业未来的技术创新、实现可持续渔业、开发应对渔业问题的技术以及加强国际化和工业化能力。这些方向表明，NIFS的目标是通过“研究和解决方案开发”来提高生活质量，而不是仅仅通过研究和开发提供科学技术知识。我想介绍一下NIFS在2021年在这些战略方向上取得的成就。第一项成果与加强可持续渔业资源生态和基于人工智能(AI)的海洋信息预测有关。利用先进的远程技术，首次对东海主要鱼类(鳕鱼、狭鳕、巨型章鱼)的行为特征进行了调查。韩国通过地区渔业管理机构的科学研究调查，确保了110吨南极齿鱼。NIFS通过建立基于人工智能技术的水温预测系统来应对海洋灾害造成的损失。国家水产养殖研究所的第二项成就是开发新的水产养殖育种技术，目的是生产方便食品。该研究所恢复了濒危的龙带，建立了产业化基础，并开发和分发了能承受高温的增值养殖品种巨石斑鱼的养殖培训技术。该研究所开发出了去除鱼腥味的红鲷鱼和岩鱼粉包和软鲍鱼蒸馏器，并进行了商业化。研究院还利用从独岛附近采集的乳酸菌开发了皮肤化妆品。NIFS的第三个成就是专注于环境管理，以确保水产品的安全，以及水产事故预测技术的发展。在这个

The Indonesian Archipelago has a very complex geological history, along with equatorial warm sea temperature, resulting in diverse types of coral reefs and high diversity of coral reef fish. Many livelihoods of the coastal community are dependent on coral reef fisheries. The present study aimed to determine which region and location in the Indonesian Archipelago has the most diverse and abundant coral reef fish. The archipelago was divided into four regions: the Indian Ocean, Sunda Shelf, Wallacea, and the Pacific Ocean. Data were obtained from a national coral reef monitoring program of the Indonesian Research Center for Oceanography (RCO)-the National Board for Research and Innovation (BRIN). The reef fish data were collected using the underwater visual census method, from 321 belt transects on 24 locations (districts) across the archipelago. The results show that coral reef fish diversity of the Pacific region was the highest across the archipelago for all three trophic levels, i.e., corallivore, herbivore, and carnivore fish. The Pacific Ocean region also had the highest fish abundance for the three trophic levels. Comparison among locations revealed that the best ten locations in reef fish diversity and abundance were Sabang, Mentawai, Makassar, Selayar, Buton, Luwuk, Ternate, Raja Ampat, Biak, and Wakatobi. Wakatobi reefs showed their supremacy in carnivore fish diversity and abundance, while Biak reefs were the best in herbivore fish. The abundance of corallivore fish was also considerably high in Sabang reefs, but it is still lower than in Raja Ampat, Biak, and Wakatobi reefs. These results provide empirical evidence that the coral reefs of Wakatobi and Biak are the hottest hotspots of coral reef fish diversity and abundance in the Indonesian Archipelago.

Many livelihoods of the coastal community are dependent on coral reef fisheries. The present study aimed to determine which region and location in the Indonesian Archipelago has the most diverse and abundant coral reef fish. The archipelago was divided into four regions: the Indian Ocean, Sunda Shelf, Wallacea, and the Pacific Ocean. Data were obtained from a national coral reef monitoring program of the Indonesian Research Center for Oceanography (RCO)-the National Board for Research and Innovation (BRIN). The reef fish data were collected using the underwater visual census method, from 321 belt transects on 24 locations (districts) across the archipelago. The results show that coral reef fish diversity of the Pacific region was the highest across the archipelago for all three trophic levels, i.e., corallivore, herbivore, and carnivore fish. The Pacific Ocean region also had the highest fish abundance for the three trophic levels. Comparison among locations revealed that the best ten locations in reef fish diversity and abundance were Sabang, Mentawai, Makassar, Selayar, Buton, Luwuk, Ternate, Raja Ampat, Biak, and Wakatobi. Wakatobi reefs showed their supremacy in carnivore fish diversity and abundance, while Biak reefs were the best in herbivore fish. The abundance of corallivore fish was also considerably high in Sabang reefs, but it is still lower than in Raja Ampat, Biak, and Wakatobi reefs.
