The purpose of this study is to identify challenges related to social, economic and environmental change for fishing villages and suggest the developmental direction of fishing village to actively respond to new changes. This study mainly focuses on fishing village fraternities. Its current problems are summarized as follows: shortage of labor, population aging, entry barrier against newcomers, insufficient guidance and supervision functions, lack of funds of new projects and inadequate statistics and data. The fishing village community in the modern meaning of the term can be understood as an economic and flexible social-cultural community based on openness, cooperation instead of exclusiveness and closeness, which aligns fisheries with local industries. Thus, in order for the fishing village community to improve, the followings areas required. First, strengthening capacity of the fishing village community. Second, establishing the database system and the third, reorganizing the fishing village community into a sea village community.

In order to estimate the genetic variability and differentiation in common squid, eleven isozymic loci, coded for nine enzymes detected by starch gel electrophoresis, were scored from nine spawning cohorts in four localities. The expected average heterozygosity ranged from 0.00019 (between II-S$_2$ and Na-W) to 0.00814 (Between Bu-S and Na-W) in nine different spawning cohorts in four localities. A dendrogram, based on genetic distance mentioned, illustrated that nine different spawning cohorts were divided into three groups, similar to the result estimated by their ecological characterizations. From these results, we estimate that the common squid distributed throughout Korean waters will maintain this gene exchange. It is postulated that either the summer or the autumn spawning cohort has developed a local population that is isolated by hydrographic factors.

This paper was carried out from 15 June to 24 December in 2000 in Lake İznik of Turkey, to determine catch per unit effort (CPUE) and size composition of crayfish, Astacus leptodactylus Eschscholtz 1823, captured by fyke-nets of local fishermen. The average CPUE of all size groups was found as 1.65 crayfish/fyke-net/night for fishing season in 2000, but 26.4% of which was below the legal minimum size (crayfish<90 mm). The average CPUE of legal-sized (crayfish$\geq$90 mm) crayfish was 1.10 crayfish/fykenet/night. The annual catch of crayfish was estimated as 2990 tonnes. The length and weight compositions of crayfish captured in the fyke-nets have varied between 60 and 130 mm, and 6 and 71 g, respectively. The mean length and weight were found as 95.5 mm and 28.8 g for all size groups and 100.1 mm and 33.0 g for legal-sized individuals.

The nomenclature of the sea nettle jellyfish from Korea was initially described as Dactylometra quinquecirrha Agassiz, 1862. However its identity has been questioned on the basis of its local distribution and molecular data. Here, we examined morphology and DNA sequences of nuclear rDNA using specimens collected from southern Korean waters in August 2014. Based on morphological characteristics (bell size, umbrella pattern, number of tentacles and lappets) and distribution locality, we reassign the Korean D. quinquecirrha to Chrysaora pacifica (Goette, 1886), and provide a re-description accordingly. The molecular identity of C. pacifica was further confirmed by comparison of nuclear ribosomal DNA sequences.

Fish is a major source of protein for the Senegalese population. Fishing plays a dominant role in the Government's policy towards generating employment. It currently generates about 100,000 direct jobs (fishermen) for nationals, of which more than 90% are in small-scale fishing. The fishing industry also contributes to Government revenue through different agreements. In addition to associated dues, fishing agreements imply a series of economic, trade and technical counterparts. Under the latest fishing agreement concluded by Senegal and the European Union (1997-2001), direct financial compensation amounts to about CFAF 32 billion. Despite its economic and social importance, the sector has to face serious disequilibria both in resource exploitation and market supply: the coastal demersal (deep lying fish) stocks with high market value (mostly exported) are fully and even over-exploited, with a serious risk of local market supply shortages looming ahead as the fishing effort shifts from locally consumed species to export-oriented ones.

Wetlands perform various functions of vital socio-ecological significance playing fundamental role in moderating monsoon tidal floods and coastal protection and generate goods and products such as fish and forest resources. The depletion of mangroves is a cause of serious environmental and economic concern to many developing countries. Problems of sustainability of mangrove ecosystems are not only technical but also socio-economic. Functions played by mangrove wetlands are of fundamental importance for society. The present study aims to identify the challenges of the mangrove wetlands of Southeast coast of Chittagong, their uses and socio-economic influence on local people, and the value of ecosystem services, and to suggest how to conserve this ecosystem in a more equitable way.

According to the report of the Korea Agro-Fisheries and Food Trade Corporation (2019), the size of the HMR food market in 2019 exceeded 4 trillion won. On the other hand, the consumption of agricultural products continued to decrease. As reported by Woo (2020) who analyzed consumer panel survey data, when the 2010 agricultural product purchase index was 100, the crop purchase index in 2019 was 72 and the vegetable and special crop purchase index was 69. Therefore, the Rural Development Administration promoted the research projects to develop the technologies for producing stably raw materials of HMR and for optimizing local foods as HMR ingredients. Researches on the development of HMR using local agricultural products has been being promoted in Cheonan, Chungju, and Jeju in 2020. In the case of Jeju, it has been prepared and realized the B2B commercialization of Jeju agricultural products in connection with the convenience store ingredients supplier in the province. In the case of Cheonan, development of HMR foods like as Sundae, dumpling, sausage, and Tteokgalbi using willd chive, cherry tomatoes, shiitake mushroom, fortified perilla, and licopene fortified watermelon has been being promoted. Lastly, in the case of Chungju, a diverse HMR foods have been developed using beans, centella asatica, Japanese lady bell, apples and peaches such as blended juices, frozen boiled rice, and tofu kit. In the future, in connection with the regional specialized crop cultivation project promoted by the Rural Development Administration, we intend to support the convergence commercialization of R&D technology based on regional characteristics.

A number of public loans with lower interests and other tax benefits have been provided for farmers and fishermen. However, much of those loans have been accumulated as non-performing. The result is that a large part of fisheries debts are now on the verge of default, Those loans, that fail to pay interests, keep rapidly growing like a time bomb. Now something has to be done before it burst. Firstly, the government must clean up the debts caused by government's mismanagement in the past. The past debt must be repaid or written off by the government since its guarantee was committed several times in guidelines regarding public loans. As such a measure, the government can greatly enlarge its capital contribution to the Credit Guarantee Fund for Farmers and Fishermen and Loss Guarantee fund for Policy Loan. It would greatly help to compensate local branches of fisheries cooperatives for their loss incurred from carrying public loans. In the past, the government used to roll over old debts of fishermen with new debts whenever maturity came. It ends up growing the size of non - performing loans. For this reason, it is not delay of the debt payment, but its write - off that fishery society needs a lot. Secondly, the loan authorities must lower overall risk in providing public loans for fishermen in the future. The whole process must be thoroughly reviewed and changed to provide and manage government loans. To facilitate this, fisheries cooperative must stop being just a public agent, rather take a bigger responsibility in selecting, and checking loan beneficiaries, and securing debt repayment. Incentives must be arranged properly enough to induce fisheries cooperatives to treat public loans just like their own business. Finally, the so - called 'special account of policy loan in fisheries industry' must be set up to enhance the transparency and to check the performance of public loans programs.

The barren ground is an abnormal phenomenon of coastal ecosystem in which seaweeds, are destroyed and mostly replaced by the coralline algae containing the calcium carbonate components. To restore the seaweed forest, We have exerted an effort in the local areas, Samchuck, Korea, where barren phenomena are profound. Two methods of seaweed forest construction developed in the present study are underwater longline and seed transplantation for the brown seaweed Costaria costata, a fast growing edible seaweed. The sizes of C. costata attached on the underwater longline were $96.7{\pm}2.2mm$ of blade length and $83.6{\pm}7.7g$ of blade weight in April. Thereafter the sizes declined from May. Similar pattern was obtained from in the transplantation method with maxima of $90.4{\pm}15.8mm$ and $70.1{\pm}31.7g$ for blade length and weight, respectively in April. It appeared totality maturation from two methods in May. This maturation time is the same like that of wild C. costata.

Cameroon is a country in Western Africa with 16 million inhabitants. Located between Nigeria and Equatorial Guinea, the country is bordered by the Bight of Biafra. It has a 402 km long coastline. It covers an area of about 475,440 sq km. Cameroon obtains its fish supply from five distinct sources notably-small scale maritime Fisheries, inland fisheries, industrial fisheries, aquaculture and importation. Despite its enormous potential, Cameroon produces only 180,000 metric tons fish annually. The total artisanal annual catch is estimated to be 55,000 t of which bonga/Sardinella, white shrimp and demersal fish contribute 58%, 27% and 15% respectively. The industrial fleet expanded rapidly during the sixties and by 1973 there were 29 trawlers and 13 shrimpers which landed a total of about 17,600 t of fish and shrimp. The total catch of the industrial fisheries peaked at about 20,400 t in 1976 and since then catches have generally declined. The per capita fish consumption in Cameroon stands at about 17.9 kg per inhabitant per year. This means that the demand of fish in Cameroon stands at about 280,000 tons. There is a deficit of in fish supply for which the government always resort to massive importation of fish products to meet the local demand. The main fish product for export from Cameroon is the prawn (Panacus duorarum). The main export market of Cameroon's prawn is the European Union (EU). Between 1998 and 2003, Cameroon's export value has been on the decline, dropping from 1,836 metric tons of prawns for a value of 264 millions USD in 1998 to 51 tonnes, for an estimated value of 315,000 USD in 2003. This drastic drop in exportation is consequential to Cameroon's auto suspension from the exportation of prawns towards the EU as a result of non compliance with EU standards. Today, a good quantity of the catches is being exported illicitly through neighbouring countries.
