"Ecosystem approach to aquaculture"
Development and dissemination of sustainable aquaculture technologies in the tropical area based on the eco-system approach
For fishing and farming communities in the Southeast Asian region, marine products are essential as an important source of income as well as an important source of nutrition such as protein and minerals. However, the socio-economic background of rural communities, including small-scale aquaculture operators, is becoming more complex. In order to develop and disseminate practical aquaculture technologies, an ecosystem approach is effective, in which local needs and the use of aquaculture fishing grounds are thoroughly discussed with relevant stakeholders in advance. In doing so, multiple scenarios can be presented as a decision-making tool for the community, enabling them to understand and share the direction of environmentally harmonious and sustainable aquaculture.
Ecosystem approach: A process for humans to use natural resources sustainably and rationally without destroying them while preserving ecosystems.
The project will develop and disseminate sustainable aquaculture technology in the tropics by applying community-based aquaculture farm management that maintains ecosystem functions (ecosystem approach to aquaculture), and improve the nutritional status of local communities by stabilizing the supply of aquatic products.
- Enhancement of sustainable aquaculture technology adapted to tropical regions and improvement of nutritional status of local residents
- Development of aquaculture systems that introduce high-value seed production and intermediate breeding in harmony with the environment in the tropics

Report on the JIRCAS International Symposium 2022 “Artisanal Fisheries and Aquaculture in the Sustainable Food Systems”
The JIRCAS International Symposium 2022 “Artisanal Fisheries and Aquaculture in the Sustainable Food Systems” was held in hybrid format at Hitotsubashi Hall, Hitotsubashi University and online on November 22, 2022 under the auspices of the Ministry of Agriculture, Forestry and Fisheries (MAFF) and the Japan Fisheries Research and Education Agency (FRA).
Methane from cow and sheep burps is one of the greenhouse gases thought to have a significant impact on climate change. Recently, it has been shown that methane emissions from cattle can be reduced by feeding them seaweed. The seaweed called Asparagopsis is particularly effective in suppressing methane emissions and has attracted considerable interest. The cultivation of seaweed for methane reduction is now being started all over the world and is expected to become a new seaweed industry.
June 8 is World Oceans Day. It was established to create an opportunity to raise global awareness of the challenges facing the international community regarding the oceans. Also, 2022 is the International Year of Artisanal Fisheries and Aquaculture. In today's Pick Up, we introduce two examples of international joint research related to small-scale fisheries and aquaculture in the field of fisheries featured in the JIRCAS Research Highlights.
Pick UpThe Japanese people love shrimp, and in 2019 they consumed more than 230,000 tons of shrimp annually, making them the second largest consumer per capita in the world, after the United States. According to government statistics, about 70% of the shrimp imported to Japan comes from Southeast and South Asian regions such as Vietnam and India. Shrimp caught in these countries were exported until the 1980s, but since the 1990s, production has shifted mainly to aquaculture due to dwindling resources. In addition, 2022 is the International Year of Artisanal Fisheries and Aquaculture. In this Pick Up, we will introduce some of the less commonly known methods of shrimp farming.
