2008 - 2011
From capture-based to self-sustained aquaculture and domestication of the
Atlantic bluefin tuna
(SELFDOTT, EU 7th FP)
< 50 Fish, but survivors from 2011 spawning and cage transfer now above 5kg

In 2011 the first successful transfer to grow-out cages in the open sea was carried out and to date as can be seen from the pictures supplied by Manabu SEOKA the fish continue to grow to this date and have reached a size approaching 10kg. This year in Spain induction techniques were used again as the fish were slow in spawning probably due to low water temperatures. For grow out this year approximately 2500 fingerlings had been transferred to sea cages for fattening and growing out. The numbers of survivors from 2011 are around about 40 fish which will hopefully in 2 to 3 years be sexually mature.
In April of this year and new FP 7 project entitled: “Translation of domestication of Thunnus thynnus into an innovative commercial application.” TRANSDOTT commenced. This project involved three non SMEs from the previous SELFDOTT program together with five SMEs, Malta Fish Farming, Panittica, Futuna Blue, ARDAG and Skretting. The aim of this project is the scaling up from experimental set-ups to large-scale rearing of fingerlings
A new initiative started by collaborative discussions with various EU projects and stakeholders is that of Tuna Ocean Restocking (TOR). This is based upon the establishment of four to six broodstock centres which can be either cage based or land-based the placed near to known spawning areas for aBFT. All the broodstock of these centres will be “fin-printed” such that we have a DNA marker for parentage.The centres will supply annually up to 200 million eggs either by induction or natural spawning which can either be directly released into the sea or at least incubated until they hatch. In this way due to the DNA marker we will be a to distribute over one billion tagged eggsinto the environment per year. One of the main problems with any restocking programme is the inability to measure the success of any restocking. It is then planned to seek collaboration with the main markets specifically in Japan whereby DNA samples can be obtained from captured fish and then compare it with a central databank provided by the broodstock centres. Within 3 to 4 years we should obtain measurable results from the market. Funding could be provided from various international sources for both the broodstock centres market sampling for DNA.
The work I have presented to you today are the results of approximately 10 years of effort by a multitude of scientists worldwide. The majority as come from projects involving funding from the European Union. It has been a tremendous experience and I must thank my many fellow collaborators for their input in time and effort into the studies. I do believe we are at the threshold of turning this into a sustainable aquaculture for aBFT as shown by the excellent example of our Japanese colleagues. The journey has been long but we can see the sun rising at the end of the tunnel.
As we see here the sun rising over the broodstock cages in Malta during 2012 may extend a welcome to anyone wishing to attend our TRANSDOTT annual meeting in the facilities of IOLR/NCM in Eilat, Israel where I hope we will be able to discuss further advances and future perspectives for tuna propagation. May I have thank you for your attention * The DOTT projects are carried out with financial support from the EEC Commission, specific RTD programme of Framework Programmes. It does not necessarily reflect its views and in no way anticipates the Commission’s future policy in this area.
