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.

Securing the future of the melon barb: Science-based aquaculture for conservation

Melon barb, Haludaria fasciata.

The melon barb (Haludaria fasciata) is a lemon-striped freshwater fish found only in the hill streams of the Western Ghats in Kerala and Tamil Nadu. Prized by the global ornamental fish trade, its wild populations are falling as deforestation, sand mining, and pollution degrade its habitat. This article sets out a science-based method for breeding the species in captivity, from conditioning broodstock on protein-rich diets to managing spawning tanks, larval feeding, and water quality. It also covers the economics: a small hatchery can be set up for a modest sum and produce thousands of juveniles per cycle, giving rural households a supplementary income. By supplying farmed fish to domestic and export markets, hatcheries ease pressure on wild stocks and support brood banks for conservation. The melon barb shows how ornamental aquaculture can link rural livelihoods with the protection of freshwater biodiversity in the Western Ghats.

Tiny guardians of hill streams: Exploring the ornamental loaches of the Western Ghats

Bhavania australis.

The Western Ghats are home to a distinctive group of small, bottom-dwelling fish: the loaches. Adapted to fast-flowing hill streams, they have elongated bodies, sensitive barbels around the mouth, and cryptic patterns that blend into rock and gravel. The region holds at least 43 loach species across 12 genera, 39 of them endemic, the result of long evolutionary isolation in mountain streams. This article describes their body forms, habitats, feeding habits, and behaviour, and profiles well-known species such as the Zebra loach (Botia striata) and the Zodiac loach (Mesonoemacheilus triangularis), both popular in the global ornamental fish trade. It also outlines the pressures these fish face, including habitat degradation, dam construction, pollution, and unregulated collection. Most Western Ghats loaches still lack legal protection, and the article reviews their conservation status and the measures needed to safeguard them.

Food and feeding habits of some peninsular carps

Carps are a vital component of global freshwater fish production, particularly in India, where both Indian major carps and indigenous species contribute to aquaculture. This study reviews the food and feeding habits of select peninsular carps, highlighting their potential for aquaculture diversification and biodiversity conservation. Indigenous species such as Hypselobarbus pulchellus, Barbodes carnaticus, Labeo fimbriatus, Labeo kontius, and Tor khudree demonstrate adaptability to natural productivity, reducing reliance on artificial feeds. Gut content analyses reveal dietary patterns ranging from herbivory to omnivory, with species consuming vascular plants, algae, molluscs, and insects. Feeding behavior varies across life stages, with juveniles relying on zooplankton and diatoms, while adults shift to macrophytes and benthic organisms. Integrating these species into polyculture systems could enhance aquaculture efficiency and support conservation efforts for threatened endemic fish.

WAS Journal Special Issue: Global Conference on Aquaculture Millennium +20 Thematic Reviews

Eight thematic reviews prepared as preparation for the Global Conference on Aquaculture Millennium +20 (GCA +20) have been published in a Special Issue of the Journal of the World Aquaculture Society "Aquaculture for Food and Sustainable Development". A group of experts prepared advanced working drafts of each thematic review and the key findings from each theme were presented and discussed by expert panels during the GCA +20. Participants were then invited to provide their feedback and perspectives on the reviews and their key messages for consideration in finalisation of the papers. The reviews are available for free download.

Genetic management of Indian major carps

Collectively carps represent the largest global aquaculture sector, contributing over 20 percent of global aquaculture production. The Indian major carps including catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirhinnus mrigala) are cultured widely across the Indian sub-continent with the main culture system being a multi-species polyculture in ponds, often including other carp species. This production sector is supported by major seed supply systems producing over 50 billion seed per annum. This case study analyses genetic management of Indian major carps since they were first domesticated with the development of hypophysation techniques in the 1950s. A review of literature and a survey of common hatchery practices identifies significant problems prevalent in the sector brought about by a lack of application of best practices in genetic management resulting in loss of genetic diversity, inbreeding and uncontrolled hybrid introgression.
