Tilapia lake virus (TiLV) is an emerging disease of cultured tilapia in the Asia-Pacific region. Originally observed and reported in Israel, Ecuador, Colombia and Egypt, TiLV is now confirmed in cultured tilapia in Thailand causing mass mortalities. At risk is here is the US$7.5 billion global industry per annum, especially among the top tilapia-producing countries in the region including China, the Philippines, Thailand, Indonesia, Lao PDR and Bangladesh. This advisory describes signs of the disease and PCR detection methods.

The fourth major international event on giant freshwater prawns was organised by the Asian Institute of Technology from 20-24 March 2007. The conference, organised by Salin Krishna and Michael New, built on a series of highly successful events that trace back to the very beginnings of the industry. The first conference, Giant Prawn 1980 brought together all those involved in freshwater prawn research and farming for the first time and set many priorities for future research and development.

Bangana dero is one of the most popular indigenous minor carps in the north eastern states of India, fetching triple the market prices of Indian major carps. B. dero is a bottom feeder and feeds on insect larvae, molluscs, algae, zooplankton and detritus. Over the last two decades the occurrence of wild juveniles of this fish in Indian rivers has fallen drastically. A protocol for induced breeding, larviculture, nursery rearing and growout including polyculture of B. dero is described.

In Nepal, low quality and seasonal access to fish seed is an important restriction on the development of the aquaculture sector. Commercialisation of fish farming cannot progress rapidly in the absence of critical inputs and a regular supply of quality fish seed is an integral requirement for the transition of fish farming from a subsistence activity to a commercial enterprise. Participatory market chain approaches are a key tool for the social and economic improvement of farmers and market participants.

These are the proceedings of a consultation on the existence and effectiveness of environmental monitoring systems for fisheries and aquaculture in the Lower Mekong basin. The document provides a baseline assessment of environmental monitoring systems in Cambodia, Thailand and Vietnam and the report of a workshop to discuss the assessments findings and future steps towards an improved environmental monitoring and early warning system that will contribute to climate change adaptation in fisheries and aquaculture in the area.

The 15th meeting was held from 21-23 November 2016, in Bangkok, Thailand. A special session was held on addressing the use of anti-microbial substances in aquaculture and the development of anti-microbial resistance. This is an issue of global concern for both human and animal health, and it had been addressed by a resolution at FAO’s Thirty-ninth Conference in June 2015. The meeting reviewed in detail the status of aquatic animal disease in the region.

The success stories of many small-scale farmers in both Asian and African countries have brought insights on the effectiveness and self-sustaining mechanism of the farmer-to-farmer approach of aquaculture extension. This document will only serve as a guide on how to implement farmer-to-farmer approaches on small-scale freshwater aquaculture extension. Translations of the guidebook are available in Arabic, Bahasa Indonesia, Burmese, English, French, Khmer, Lao, Malay, Nepali and Thai.

This Code of Practice is prepared to promote or ensure compliance to World Trade Organisation-Sanitary and Phytosanitary measures for the movement of live aquatic organisms in the Lower Mekong Basin. The goals of the Code are to achieve environmental protection and management, biodiversity conservation as well as prevention of spread of disease epizootics. Most of the points listed in this Code are based on the inputs of MRC Member Countries.
