Question

Blue Fin Tuna Aquaculture

After successful fertilized egg production in captivity the next bottle neck is larval rearing to fingerling size. Anyone has some new ideas?

    That is really true but this can be possible if you can provide enough live food during larval stage. try to wean faster if you don't have enough live food. I think the best way is to set up an artimia culture unit to produced live food for producing good fingerling with higher survival and growth
    with best regards

    Many thanks for the suggestion we have had trials with other partners at hatcheries with rotifer and then Artemia but the latest trend for live food looks like a copepod system. Do you know of any trials with marine fish and copepods apart from the work on Cod?

    Why not try a mixture of food to provide variety?. Maybe some freshwater amphipod larvae as well

    Hi Beatrice. Do you have experience using amphipod larvae as food? Can share the experience with us?

    They gave very good growth rates with seahorse fingerlings, they loved them.

    Google Scholar for Copepods+red snapper. There's a wealth of info. See also: http://nsgl.gso.uri.edu/flsgp/flsgph07002.pdf for the Acartia tonsa culture manual.

    You might also contact Patrick Tracy at LinkedIn: http://www.linkedin.com/pub/patrick-tracy/37/141/497 He has conducted research in Panama on Tuna aquaculture and may have useful information.

    Hi,

    we now have evidence from work this year with Futuna Blue that copepods work extremly well and a new micro diet from Skretting can be used at a realatively early stage to increase survival rates A new project TRANSDOTT has just taken off and will be pushing the sustainable aquaculture boundaries even further.

    Larvae of earth worm is also another live food of blue fin fish. It can be collected from sewerage drain. Artimea is also good live food for this species.
