Sri Lanka

Sri Lanka is home to more than 12,000 reservoirs, one of the highest densities of freshwater bodies globally. Originally constructed for irrigation, domestic water supply and later hydropower generation, these reservoirs have increasingly been used to support culture-based fisheries.

Culture-based fisheries have significantly enhanced inland fish production and emerged as a vital source of low-cost animal protein and household income for rural communities. By 2017, production from culture-based fisheries reached approximately 83,000 tonnes annually, contributing meaningfully to national food security and rural livelihoods. However, the absence of a solid foundation of science-based knowledge and evidence-based practice has limited its capacity for sustainable expansion and innovation.

This publication presents information from an end-of-project workshop held in Colombo, Sri Lanka, in February 2025. The papers were drawn from an ACIAR-supported research project, Improved productivity, efficiency and sustainability of the culture-based fishery for finfish and giant freshwater prawn in Sri Lankan reservoirs.

• Third Asia-Pacific Laboratory Proficiency Testing Program for Aquatic Animal Diseases launched.

The third Asia-Pacific Laboratory Proficiency Testing Program for Aquatic Animal Diseases has been launched, with a regional workshop in Bangkok bringing together 50 people from 13 countries and territories across the region. The program, supported by the Australian Government Department of Agriculture, Fisheries and Forestry and CSIRO’s Australian Centre for Disease Preparedness, builds on more than a decade of collaboration to strengthen diagnostic capacity, safeguard aquaculture livelihoods, and support safe trade and food security.

In 2023, FAO and NACA initiated a consultation process on aquaculture effluent management in Asia and the Pacific in collaboration with NACA member governments. Experts across the region gathered information to assess the state of governance, advancements in technology and innovation in aquaculture effluent management. The consultative process culminated in an expert workshop, convened from 14 to 15 November, funded by FAO, to share views and national experiences on aquaculture effluent management.

Risk analysis is an essential component of a national aquatic organism health strategy. Now widely applied in many fields, risk analysis provides a science-based framework for evaluating hazards, determining the likelihood and extent of potential harms, mitigating risks and guiding policy decisions. Combining risk and value chain analysis provides a risk-based and people-centred approach to managing disease risks and planning control measures for aquaculture systems. FAO organised a training course on Risk Analysis in the Value Chain from 3-5 September in Bangkok, Thailand, in partnership with NACA, INFOFISH, Thailand Department of Fisheries and the ASEAN Network of Aquatic Animal Health Centres. Financial support was provided by the Norwegian Agency for Development Cooperation and Thailand Department of Fisheries.

Join us on 31 May for a free webinar on Culture-based fisheries for rural development, with leading experts from the Asian region. Culture-based fisheries (CBF) are practices to enhance fish stocks in waters that don't have enough natural recruitment to sustain a fishery. CBF practices are usually applied in small water bodies such as village dams and irrigation reservoirs. Fish growth is driven by the natural productivity of the waters, foraging on natural food supplies. The simplicity and low capital requirements of CBF make it easy for farming communities to learn and adopt.

The 87th edition of the Quarterly Aquatic Animal Disease Report contains information from fifteen governments. The foreword discusses the 19th Meeting of the Asia Regional Advisory Group on Aquatic Animal Health, held 26-27 November 2020.

The Regional Workshop on Underutilized Fish and Marine Genetic Resources and their Amelioration organised by the Asia-Pacific Association of Agricultural Research Institutions (APAARI) was organised on July 10-12, 2019, in collaboration with the Sri Lanka Council of Agricultural Research and Policy (SLCARP) and National Aquatic Resources Agency (NARA) in Sri Lanka. About 95 participants from thirteen countries of Asia-Pacific region participated in the workshop. The perspectives gained will be instrumental in increasing awareness of the importance of underutilised aquatic genetic resources and to formulate strategies for strengthening their sustainable use at the regional level. 

The workshop was held from 10-12 July 2019, Colombo, Sri Lanka. The objectives of the workshop were to i) assess the current status of underutilised aquatic genetic resources at the regional level and to assess R&D status of priority species with potential for use in food and agriculture; ii) discuss knowledge gaps and regional priorities concerning underutilised genetic resources and create awareness on their role and value for diversification of food supplies and livelihoods; and iii) formulate strategies for strengthening the institutional framework for management and conservation of genetic resources at the regional level.

Two consultations were held back to back in Thailand from 5-7 November, namely the Consultation on Strengthening Governance of Aquaculture for Sustainable Development in Asia-Pacific and the Consultation on Demographic Changes in Fishing Communities in Asia. The consultations were held at the Centara Grand Hotel at Ladprao, Bangkok. The consultations were attended by 29 participants from 15 countries in the Asia-Pacific region. The consultations were jointly organised by FAO and NACA. Audio recordings are available of some presentations.
