This paper revealed the change of structure in coastal fishing management entities and trend of person who engaged coastal fishing by analyzing of 2018 year fishery census.

The analysis showed importance of grasping the actual condition of fishing household, for example, labor force status of family member of fishing household, presence of fishing successor because almost of coastal fishing management entities consist of fishing household （independent management）.　Also use of statistics for sustainable fishing community was considered in this paper.

In recent years, the fishing industry has shrunk, and the marine product processing industry has become unstable due to sluggish profit margins and other factors.　However, utilization of foreign nationals is increasingly active in these industries.　The fishing and marine product processing industries are struggling to secure Japanese workers due to a declining birthrate and an aging society, and employment of foreigners has become essential.

In this paper, the actual employment situation of foreign nationals in the fishing and marine product processing industries and the increasing dependence of these industries on foreigners are clarified based on the employment situation and trends concerning foreigners identified in the fishery censuses.　Regarding the fishing industry, analysis was carried out by organization class and fishery type, and the general picture of employment trends in Japan was approached by specifying prefectures and municipalities with many foreigners.　For the marine product processing industry, the national trend was approached by analyzing data on the dependence on foreigners by processing plant employee numbers and by region.

Our analysis revealed that despite the decline in foreigners working on so-called Maru ships （i.e., Japanese ships） amid shrinkage of deep-sea fishing, dependence on foreign technical interns is expanding in offshore fishing and labor-intensive shellfish aquaculture.

As of 2018, the marine product processing industry had 17,336 foreign workers─about three times the number of foreign workers in the fishing industry─and it was revealed that production plans were being created and production activities carried out based on their existence in the industry.

The purpose of this paper is to clarify the actual state of today’s fishing communities using the results of 2018 Fisheries Census in Japan.

In our country, more than 80% of districts experienced a decrease in the number of fisheries management bodies in 10 years from 2008 to 2018.　There were also 114 districts with no fishery management bodies in 2018.　In addition, the number of fishing districts with more than 50% of fishermen aged 65 and older increased in 10 years from 2008 to 2018.　The pace of aging in the fishing industry is gradually accelerating.

Securing successors is important for the stable existence of fishing communities, but nearly half of all fishing districts have less than 10% of fisheries management bodies with successors.　On the other hand, the ratio of securing successors varies considerably from district to district.　The common characteristics of the fishing districts with high succession rates in Hokkaido showed that the succession rate tended to be determined to some extent by types of fisheries and the level of the fishing income.

The efforts for fisheries management are being implemented by fishers in about 90% of the target districts.　The result shows that fisher’s awareness of resource management is widely spread in Japan.　In addition, activities for the revitalization of fishing communities utilizing various local resources have been widely conducted in fishing districts across the country.

From the above, we can see that the number of fishers has been steadily declining and aging in Japan, and there are some districts that are in danger of existing in the future.　It is also true, however, that the current state of fishing district is different depending on natural, social, and economic conditions.　We need to deepen our understanding of the conditions for existing of today’s fishing communities from the field survey, and to examine the possibility of realizing a sustainable society based on fishery.

In this report, I took up the major types of aquaculture in Japan and clarified their current situation from the fisheries census statistics.　In addition, focusing on fish aquaculture, I analyzed the 2018 census and clarified its structural changes.

On the whole, the number of fish farming enterprises is decreasing significantly, especially in the fish farming industries such as yellowtail farming.　In fish farming, expansion of scale has a great significance in improving productivity per worker, and expansion of scale is becoming a necessity to ensure competitiveness.　On the other hand, in non-feeding aquaculture, there is no significant difference in productivity depending on the scale, and there is no clear merit in scaling up.

A small number of large corporate entities have come to hold a large market share, and their actions now have a significant impact on the overall trend of the aquaculture industry.

With the revision of the Fisheries Act, the aquaculture industry is likely to see more of this type of external capital and technology.　The existing aquaculture industry is also developing like a food industry by integrating with land-based industries.　Census statistics should evolve in order to capture these new situations.
