Scientists at the ICAR-Central Coastal Agricultural Research Institute (ICAR-CCARI) have successfully standardised captive breeding protocols for some of Goa's threatened indigenous ornamental fish species, a breakthrough expected to reduce dependence on wild collection for the aquarium trade while strengthening conservation of the State's unique freshwater biodiversity.
The institute has reported successful captive breeding of five key small indigenous freshwater fish species -- Haludaria pradhani (endangered), Pethia setnai (vulnerable, Rasbora dandia, Systomus sarana and Puntius vittatus.
Among the most significant achievements is the breeding of Haludaria pradhani, commonly known as the Melon Barb, an endangered ornamental fish endemic to the Southern Western Ghats, including select freshwater habitats in Goa. Valued for its striking orange-and-black colouration, the species has long attracted aquarium hobbyists but faces mounting pressure in the wild.
The institute said it has standardised captive breeding protocols for the species, from broodstock conditioning and spawning to larval rearing, enabling fish to be produced outside their natural habitats.
“This approach not only ensures ex situ conservation but also provides a sustainable alternative source for the aquarium trade, reducing pressure on wild populations,” the report said.
ICAR-CCARI has also successfully bred Pethia setnai, or the Indigo Barb, another endemic ornamental fish confined to select river systems of the Western Ghats in Goa. The fish, recognised for its metallic blue sheen and black markings, is considered to have considerable potential for both conservation and ornamental aquaculture.
The report said captive breeding of the Indigo Barb could simultaneously support conservation and create new livelihood opportunities.
“Captive breeding of P setnai supports its ex-situ conservation and provides opportunities for livelihood diversification through the ornamental fish trade. These efforts, combined with in situ habitat protection, form an integrated approach to preserving the species' genetic diversity and ecological role in its native rivers,” it said.
The institute's two-year survey across 16 freshwater ecosystems also documented 84 fish species in Goa, including eight species listed as threatened by the IUCN Red List, underlining the urgency of conservation efforts amid habitat degradation, pollution and invasive species.
Beyond conservation, ICAR-CCARI sees economic potential in indigenous ornamental fish culture. The report recommended expanding captive breeding, decentralising broodstock centres and integrating native ornamental fish culture with livelihood initiatives to reduce reliance on wild capture while generating sustainable rural incomes.
