Genetics and Biodiversity

The Genetics and Biodiversity Programme supports member states to improve scientific knowledge of aquatic genetic resources and to guide strategic planning in their management. The programme addresses both the conservation aspects of genetic resources and their responsible usage in aquaculture to minimise impacts on biodiversity and wild strains and to assist members to meet their obligations under international treaties.

The programme promotes international linkages between member states, capacity building, research programs to develop improved strains of finfish and shellfish, genetic characterisation of existing strains, adoption of new genetic tools and technologies and consortia regional programmes to address common issues, species and strains of value from conservation and/or aquaculture perspectives.

Key activities

Key activities of the programme include:

  • Building capacity in aquatic genetic resource management and application of new molecular technologies, tools and strategies.
  • Characterising aquatic genetic resources to discover species, stocks and valuable genomic resources.
  • Facilitating national and regional programs for domestication, genetic improvement and conservation.
  • Applying conservation aquaculture models to support diversification, fishery enhancement and in-situ conservation of indigenous fish species.
  • Facilitating responsible exchange of germplasm, safe propagation and access-benefit sharing.

Invasive apple snails (Pomacea spp.) in Vietnam: Short review

Originating from South America the apple snail species of Pomacea, commonly referred to as golden apple snail, was imported into Vietnam from 1985 to 1988 with the intention of raising it for human consumption. Not long after that, the introduced snails quickly spread to most freshwater ecosystems of the country. This review examines the current status and history of apple snail introduction in Vietnam, and the various control and management measures used to cope with snail infestations.

Video lectures: Regional Training Course on Culture-based Fisheries in Inland Waters

This collection contains video recordings of the lectures from the Regional Training Course on Culture-based Fisheries in Inland Waters, held at Nha Trang University, Vietnam. The objective of the course was to provide participants with the skills to assist local communities to plan and manage culture-based fisheries; a relatively simple and low cost technology that can deliver nutritional and economic benefits to rural communities with few livelihood options. The course was sponsored by the United Nations University Fisheries Training Programme.

First training course on culture-based fisheries held in Nha Trang, Vietnam

The first ever Regional Training Course on Culture-based Fisheries in Inland Waters was held at Nha Trang University from 30 October to 8 November. The objective of the course was to provide participants with the skills to assist local communities to plan and manage culture-based fisheries. These practices are an example of a relatively simple and low cost technology that can deliver nutritional and economic benefits to rural communities, which often have few livelihood options.

Biology and Management of Invasive Apple Snails

Apple snails have become a major pest of wetland rice in much of Southeast Asia. Two species are involved, Pomacea canaliculata and P. maculata. One or both of these species have become widely established not only in many parts of Southeast Asia but also in other parts of the world. This book provides an update on research into the biology, management and use of apple snails and highlights the need to prevent further spread of these species.

Giant Prawn 2017

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.

Development of regional code of practice for movement of aquatic organisms in the lower Mekong basin

The objective of this project was to develop an agreed code of practice for the transboundary movement of aquatic organisms that feeds into the fisheries management strategy for the lower Mekong basin. The code of practice provides guidance on risk management and mitigation measures be taken into account for live aquatic animal imports or other transfers that are part of the established commercial practice, or those related to scientific study at research facilities.

Final Draft Code of Practice for Trans-boundary Movement of Aquatic Organisms in the Lower Mekong Basin

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.

Sustainable intensification of aquaculture in the Asia-Pacific region: Documentation of successful practices

This publication is the major output of a regional programme jointly implemented by FAO and NACA in 2015 to document and disseminate successful practices that contribute to the sustainable intensification of aquaculture in the Asia-Pacific region. Twelve practices are described that contribute to at least one of the following: Improved production and resource use efficiency (land, water, feed, energy); improved environmental benefits; strengthened economic viability and farmers' resilience; and improved social acceptance and equity.

Genetic considerations in culture-based fisheries development in Asia

A shift away from exotic speces towards the use of indigenous ones was believed to counter negative impacts of culture-based fisheries. However, hatchery-produced fingerlings can also pose a potential threat to genetic diversity and integrity of their wild counterparts. This paper entails the pros and cons in the use exotic vs. indigenous species in CBF and steps to be followed when decisions are made on species choice for CBF.

Future considerations for the domestication and breeding of penaeid shrimp

Domestication in livestock industries is the process in which animal populations change in response to the artificial environments of farming production systems. Significant and widespread economic gains have been achieved through genetic improvements made through domestication and selective breeding of commercially farmed shrimp species, particularly Litopenaeus vannamei. Different policies on the translocation of shrimp genetic resources have influenced the approaches to shrimp domestication in different countries. The present paper examines the different approaches.

Inbreeding and disease in shrimp aquaculture: A reappraisal and a caution

Tropical shrimp aquaculture is facing a disease crisis that may be propelled by an interaction between management practices that cause inbreeding, and the amplification by inbreeding of susceptibility to disease and other stresses. Broodstock accumulate inbreeding and lose genetic diversity when they experience bottlenecks or are chronically too small. The genetic lock is a practice that leads to inbreeding at farm level. Inbreeding may be amplifying the severity of diseases, including the major current threats.
