Technical publications

NACA publishes technical papers and manuals for a wide variety of farming systems and related environmental and social issues. Many of these provide guidance on better management practices with a view to improving crop outcomes and on-farm resource utilisation efficiency. By using inputs such as feed and power more efficiently, farmers can simultaneously improve their profitability and environmental performance.

Case study on the impacts of climate change on milkfish pond production in Panay Island, Philippines

This case study examines the impacts of climate change on milkfish farmers in Iloilo. Farmer perceptions of climate change, attitudes and adaptation strategies were mapped via focus group discussion, stakeholder workshops and questionnaires. Measures that could be achieved to reduce vulnerability to climate change include sustainable aquaculture practices; diversification of farmers’ income sources; diversification of culture species; utilising natural resources to increase productivity; and building farmer capacities through access to information and knowledge.

Impact of climate change on culture-based fisheries in seasonal reservoirs, Sri Lanka

The present study identifies changes in reservoir filling patterns and water retention period of seasonal reservoirs in Sri Lanka in five administrative districts from 1960 to 2010. Results reveal that there is high drawdown in the recent past in seasonal reservoirs compared to the 1960s, and a forward shifting pattern of drawdown due to altered rainfall patterns. These changes have affected the culture season and the duration of the culture period of stocked fingerlings in the reservoirs.

Case study: Vulnerability and adaptation to climate change for catfish farmers in the Mekong Delta

The catfish industry in the Mekong Delta faces several risks and challenges including disease, environmental issues, fluctuating price, higher quality requirement of the product, and climate changes, including salt water intrusion. The different production zones were found to be different in terms of their climate change impacts, productivity, culture system and socio-economic characteristics. This study examines farmers perceptions of climate change, scientific and policy support requirements and potential adaptation strategies to sustain the industry.

Vulnerability and adaptation to climate change for polyculture systems, Vietnam

The shrimp farming case study was conducted in Cà Mau and Bạc Liêu provinces, Mekong Delta, Southern Vietnam by: (1) organized stakeholder workshops to map farmer's perceptions, adaptation measures and agencies involved; and (2) questionnaire survey to assess vulnerability of the production system to climatic changes and extreme climatic events. Farmer perceptions of climate change and possible adaptation measures were identified. Policy frameworks including the policy options were recommended and an action plan proposed.

Guide to establishment of community-based aquaculture management groups

This practical manual "Guide to establishment of community-based aquaculture management groups" was prepared by the national team of Vietnam under the ASEAN Foundation supported project "Strengthening capacity of small holder ASEAN aquaculture farmers for competitive and sustainable aquaculture".

Self-use manual on group formation and group certification of small-scale aqua-farmers

This manual is intended for the use by the current and prospective small-scale farmer groups who are interested in obtaining accreditation for their production process. The objective is to provide them an easy-to-follow, stepwise guide that can be used as a practical tool in their venture of attaining group certification. However, this can be used by the field extension officers and certifiers who are directly involved in the process or other interested parties.

Better management practices for grouper culture in Indonesia: A practical manual

This practical manual covers key aspects for successful grouper farming including formation of farmer groups, cage crop planning, crop calendar and better management practices for cage aquaculture of grouper. These include site selection, design, cage preparation, seed selection and stocking practices, feed, water and health management, harvest and post-harvest, record keeping, marketing and capital strengthening. It is designed for use by small-scale farmers.

Better management practices for seaweed farming (Eucheuma and Kappaphycus)

This practical manual "Better management practices for seaweed farming" is produced by the Philippines national team under the ASEAN Foundation supported project "Strengthening capacity of small holder ASEAN aquaculture farmers for competitive and sustainable aquaculture" implemented by NACA in five ASEAN countries. The long-term objective of the project was to assist ASEAN small- scale aquaculture farmers improve their livelihoods by being competitive in markets and improving farm management practices to deliver quality and sustainably produced aquaculture products.

Shrimp price study, phase III: Case studies in Vietnam, Indonesia and Bangladesh

This study is a continuation of “Evaluation of the impact of the Indian Ocean tsunami and US antidumping duties on the shrimp farming sector of South and South-East Asia” with the aim of assessing the impact of the 2004 Indian Ocean tsunami and the introduction of anti-dumping duties on shrimp farming in the Asian region, with special focus on the effect that these unforeseen events had on shrimp prices and livelihoods of the stakeholders.

Supporting and demonstrating small scale shrimp farmer group to access international market through certification

This project was conducted to demonstrate small scale shrimp farmer group access to international markets through certification schemes. This project proved that small-scale farmers organised into groups, can improve their technical capacities, and achieve access to markets. This achievement was the result of strong partnerships with producers, private sector and government agencies assisting to develop a sustainable business model for small scale aquaculture. Cost of compliance was found to be a significant barrier to entry.
