The primary purpose of this paper is to analyze the membership of fishing community. In order to become a member of fishing community, some conditions are needed both the member of local fisheries cooperatives and resident of fishing village. Generally, many fishing communities have additional conditions such as to be a member of fishing community that is a minimum term of residence, an entrance fee, fishing abilities. These additional conditions play a critical role in making a relationship, building trust and enhancing fairness. However, the setting of excessive additional conditions make it possible to obstruct growth of fishing community.

The purpose of this study was to analyze the conditions of small fishing village & fishing port and to suggest the development direction of them. For this, we tried to field survey and research of development demands for 100 sample places. The results of this study were as follows; First, Small fishing villages & fishing ports have different characteristics and their primary industry was a fisheries. And they have a poor condition for basic facilities and industrial facilities, more smaller fishing port. Second, The living satisfaction of residents was decreased gradually because of a decrease in amount of catching fish, a population aging and etc. Residents and public officers was to demand an expansion of basic facilities, an investment of national expenditure and a simplification of administrative procedure. Third, We could establish the development directions by geographical location and funcion of them. And They must development consider their characteristics.

The purpose of this study is to draw up a plan for improving working conditions of distant water fishing vessel crew in order to revitalize the declining distant water fishing industry. Land-based employment has increased as the result of industrialization, which in turn created shortage in marine crew supply for distant water fishing vessels. Pressure on increasing wages for sea farers is put on the industry for this reason, making the labour market in the distant water fishing industry tougher and tighter. Multiple issues have yet to be addressed for distant water fishing vessel crew. They suffer from excessive work compared to other industries. Crew management is another issue, as sea farers face poor labour conditions, working on board vessels in a collective way where no autonomous actions are allowed. Other issues include unqualified crew supply, increasing ratio of labour costs for crew to sales, and intensified implications of labour unions, which are as well making crew supply difficult as a whole. To this end, more well-qualified workers should take part in production operations in the distant water fishery. Both wage increase and working condition improvement should be achieved in order to strengthen motivation towards qualified sea farers. Sustainable crew supply can be achieved when working environments, gender-based working conditions, welfare are prioritized and improved as a whole.

In Korea, deep-sea fishing industry is faced with pressure of being thrown out of business, because of the upcoming unfavorable business conditions such as the fishing regulation of coastal countries, Korea-US Free Trade Agreement(KORUS FTA), and the other socio-economic changes. Hence, we present an evaluation of future business competitive for the deep-sea fishing industry so that the government can develop a concession plan for the deep-sea fishing industry by utilizing the results of this study. In efficiency analysis of deep-sea fishing industry, the decision maker may have two problems: (1) how to deal with multiple inputs and outputs of deep-sea fishing industry and (2) how to assign the weights on different inputs and outputs, In this paper, we proposed to use Data Envelopment Analysis (DEA) to estimate efficiency of deep-sea fishing industry with multiple inputs and outputs. In the DEA, The direct impact of KORUS FTA, fishing regulation of coastal countries, fishing charges, and competitive fishing conditions were used as input parameters while the profitability and secured fishing quarters, as outputs. The results of DEA-BCC model indicate that 6 out of 12 DUMs have better efficiency under variable return to scale assumption.

Since the middle of the 70s, the countries with the marine resources declared the exclusive water zone of two hundred miles. As a result, our country lacked many foreign fishing grounds. This awakened our perception of fishing grounds. The fishing ground is an important factor in the economical effectiveness of fisheries. The fishing ground must have the following basic conditions. 1. It must be the place the fishery resources inhabit and wander. 2. Their catching or aquaculturing must be possible by the technical methods. 3. It must have economic worth in the management. The fishing ground that achieves the above basic conditions is affected by the following factors. This is the factor of the fishing ground location. A. Natural factor 1). Suitable climate 2).Abundant resources 3). Good quality of the sea-bottom 4). Not to be pollutted area B, Economic factor 1). Be adjacent to fishing port and fisheries market 2). Good working conditions 3). Be abundant of economical resources C. Social factor 1). Be possible to work legally 2). Be permitted in the political relations 3). Be acquainted with the customs of foreign countries The fishing ground location is mainly affected by the natural factor of the above factors. The abundance of resources depends on the natural resources. The resources in the fishing ground have the cycle of developing period, maturing period, and decaying period according to the fishing efforts. The point that we sustainably yield the maximum of fishery resources is the changing point of maturing period and decaying period. We call this point MSY, so the resources of fishing ground should be managed by the MSY. Therefore, when we select the fishing ground location. We should judge the natural factor, the economic factor and the social factor synthetically according to the situation and environment, so we can achieve the efficient management.

To suggest more efficient fishing operation, it was analyzed using five years (2011~2015) catch data of six Korean-flagged tuna purse seiners (with 1000 mt of haul capacity) operating in the western and central Pacific Ocean. In terms of annual total catch, it presented a two-year cycle of variation on catch, showing that catches of 2012, 2014 and 2015 were high, whereas those of 2011 and 2013 were low. The proportions on fishing effort of associated set were around 21.9~30.8% having 21.5~45.0% of total catch. In this study, there was no significant difference between catches of unassociated set and associated set. When considered having good fishing conditions, fishing activities were concentrated in the areas of Papua New Guinea (PNG) and Kiribati, while it showed that fishing ground spreaded out to the areas of not only PNG and Kiribati but also Federated States of Micronesia (FSM), Tuvalu and Solomon islands. The average number of fishing days was 271 with a range of 246~285. As restriction on fishing operation such as reduction of fishing days and higher fishing fee are expected to strengthen, the result of this study will be helpful to select more efficient fishing methods for purse seine fishery based on fishing conditions.

In order to offer data about fisheries resources management and prediction of catch on large purse seine fisheries, the fluctuation of the fisheries condition and distributions of fishing ground for mackerel were analysed with monthly catch data for 1990.2009. The overall catch has decreased to about 70% since 1997, with approximately 70% of the mackerel (Scomber japonicus) catch and monthly fluctuations showing a similar pattern. Monthly distribution of fishing ground is like distribution of mackerel in large purse seine fishery. The main fishing grounds are near Jeju Island and the Yellow sea with the main fishing season existing between October to December. The catches fluctuations and distribution of fishing ground were related to the effect of regime shifts. Therefore, in order to prediction of catch on large purse seine fisheries should be studied these relationships.

We consider changes in the fishing ground of the small yellow croaker Larimichthys polyactis and discuss their utility in predicting fishing conditions for this species. The fishing ground, which having been formed around Jeju Island since the 1970s, is dominated by the Yellow Sea Bottom Cold Water (YSBCW), and variation in its southward expansion from the Yellow Sea is the single most key environmental factor affecting the L. polyactis catch. When the YSBCW showed strong expansion and the fishing ground shifted to the west and southwest of Jeju Island, as occurred in the late 1980s, late 1990s, and early 2000s, the L. polyactis catch was low; conversely, when expansion was weak, as in the early 1990s and late 2000s, the L. polyactis catch was high. This relationship was statistically significant and should be useful in predicting fishing conditions for L. polyactis.

A large percentage of maritime accidents in coastal seas are related to small fishing vessels. In order to investigate causes of maritime accidents, it is often necessary to carry out dynamic simulations for the estimation of trajectories and motions of vessels. Initial conditions of vessels such as main dimensions, loading conditions and hydrostatic properties are required for the accurate simulations. Small fishing vessels usually have few records of hydrostatic properties during their fishing operations. Therefore, in this study, estimation procedures for hydrostatic properties of small fishing vessels are proposed. At first, hull form characteristics of Korean small fishing vessels are investigated. Most of vessels have hard-chines and centerline skegs, they have similar hull forms. Bonjean curves of several small fishing vessels whose gross tonnages are below 10 tons are normalized with vessel breadths and depths. Representative bonjean curves are derived from normalized bonjean curves, and a representative hull plan is obtained as well. If the vessel loading conditions such as total weights and centers of gravity are given, fore and aft drafts can be calculated by using the representative bonjean curves with the constraint that weights and buoyancies are in equilibrium. Metacentric heights are also estimated by using the representative hull plan. Drafts and metacentric heights estimated by proposed iterative estimation procedures are compared with actual vessel data, estimated values are in good agreements with actual values. In addition, normalized fore and aft drafts, metacentric heights of vessels can be formulated as the linear functions of normalized total weights and centers of gravity. Empirical formulas of drafts and metacentric heights are proposed, and it is confirmed that the empirical formulas also provide reasonable results, which are similar to the results by iterative estimation procedures with representative bonjean curves and hull plan.
