    Tropical Fish Breeding to Improve as a Result of New University Collaboration

    Pioneering new techniques will enable leading aquarium visitor attractions to breed their own tropical fish, following a new collaboration. The larvae of many tropical fish species are so small, that they are invisible to the naked eye, and their food source is even more microscopic. This makes captive breeding of these fish challenging. But aquaculture experts at Bangor University believe that they can help the aquarium industry to develop techniques to rear their own coral reef fish from captive larvae.

    The Zoological Society of London (ZSL), The Deep and SEA LIFE, three of the UK’s leading aquariums are working with Bangor University’s School of Ocean Sciences to develop ways of breeding and farming coral reef fish. This collaboration is part-funded by the European Regional Development Fund through the Welsh Government’s SMARTExpertise programme. Concern over the sustainability of wild collection is the driver for the aquarium sector to search for sustainable alternatives in order to reduce the ecological impact of the trade on the world’s coral reefs.

    The new project, SustaiNable Aquariums Project (SNAP) aims to increase the number and diversity of sustainably and ethically produced coral reef fish species for the aquarium community and improve the global sustainability of the trade in coral reef fish. An initial 20 tropical reef species, popular in aquariums but which have not yet been successfully captive-bred are the initial focus of the project. These include species of butterflyfish, rabbitfish, wrasse and tangs. Working hand in hand with the aquariums, who will supply the larvae, the scientists will develop new or improved hatchery production techniques, and technology and extend biological knowledge. If successful, the project could lead to the first commercial hatchery for these species in Europe, based in Wales, supplying aquariums and hobbyists across the continent.

    Tom Galley, a member of the research team at Bangor University explained “Fish developed in hatcheries are widely recognised as having advantages over their wild collected counterparts, such as being pre-adapted to life in captivity. However, for this to become a reality a significant amount of work is required.”

    Nick Jones, from Bangor University, also part of the research team on the project also explained: “The difficulty in rearing the majority of coral reef fish lies in the small size of their delicate larvae, a poor understanding of appropriate larval rearing environments, plus the lack of suitably sized and nutritious larval food items. These are issues we hope to resolve during the three-year project.”
