The SELFDOTT project has been chosen as one of the 48 EU-Funded Research projects to be presented at the
Innovation Convention in Brussels from Dec. 5-6th 2011. Over 450 applications were considered from all fields.
SELFDOTT consists of an international consortium of 13 European partners whose aim has been to breed Bluefin tuna in captivity and provide the basis for future ecologically sustainable aquaculture of this threatened species. The exhibition shows the new technologies and techniques developed to harness the reproduction of this species and monitor fish in captivity.Visitors were presented with in-situ monitoring shown together with diver assisted fish sampling and treatments, as well as live demonstrations of equipment together with video and underwater views of live tuna fingerlings produced at the IEO /Funetes facility in Cartagena, Spain
Bluefin Tuna raised in captivity to over 1 kg in just over 3 months at the Mazarron, IEO and Cartagena Fuentes facility in Spain . There are some hundreds of fish in both open sea cages and landbased tanks from this years spawning. Prospects are good for survival into next year and represent a break-through in the SELFDOTT programme.

STAKEHOLDER MEETING:" The Future of Sustainable Tuna Aquaculture - Horizons for Tommorrow" under the auspices of the IEO was held by the EU SELFDOTT group in Madrid, Spain (Aula Magna de la Escuela de Ingenieros Navales de Madrid) on the 3rd of Nov. 2011. “Sustainable Tuna Aquaculture – New Horizons “
RECOMMENDATIONS OF INTERNATIONAL STAKEHOLDER WORKSHOP MADRID 3rd Nov. 2011 (Shortened Version drawn up in Madrid)
We envisage that gamete production will continue in sea cage based structures for some time but “Land-based facilities which are being developed will provide a more controlled environment, allowing manipulation and guaranteed egg collection for a longer spawning period. An EU Network of excellence of national Centers in Europe should be financially supported together with transnational access.
SELFDOTT has established a knowledge base for larval rearing- using an integrated approach which has lead to real progress in this field. The bottlenecks which still remain are the product of the limited availability of eggs and larvae during a short spawning season. At the moment there is a lack of repeatability in results which needs to be addressed. Larval rearing is still at the research stage and has not reached the status of a commercial technology.
3.Nutrition and Diets
The SELFDOTT projects on nutrition have provided a strong foundation for future developments. Special emphasis should be placed on weaning diets and “as early as possible diets” for larvae. An alternative dry diet should be developed to replace the present supplementary reared yolk sack larvae.
Fingerling transfer and cage adaptation have been a main bottleneck in SELFDOTT and have also been seen by other research teams in Australia and Japan. The fingerling stage is extremely sensitive and the development of techniques for handling and transport require special attention.
New regulations may be required for the “new products” arising out of sustainable BFT aquaculture which may no longer fall under the remit of wild population measures. In this context traceability technologies (“farm to fork”) and distinguishing between cultured and wild populations must become standard practice for the industry. Previous legislative models for aquaculture of endangered species may serve as an example.
6. Finance and Funding?
Further public funding is required for research to close some of the gaps in our knowledge and over come some of the remaining bottlenecks. Continuing cooperative industrial support and investment is also necessary to translate research results into commercial technology.
This group strongly recommends that in future EU FP calls specific problems of the sustainable tuna aquaculture industry should be addressed.
SPAWNING SEASON CLOSES IN SPAIN AN MALTA
First batches of eggs and larvae doing well in Spain. Awaiting first transfer to open sea cages within the next week or two. Larval results from Israel, Crete and Malta show steady progression with survival rates as expected in the first 30 days. Choice of feed now at a crucial stage with YSL playing an important role and copepod suppliments being used in Mlata for the first time.
150 Million Eggs now collected in Spain 12.07.2011. The first 10,000 twenty-five DPH larvae are being weaned for sea cage transfer in 12-15 days. More batches to follow.

EUROPEAN RESEARCHERS PUSH LIMITS IN THE LAST YEAR OF SELFDOTT - SPAWNING NOW IN MALTA AND SPAIN . (latest draft egg table)
Large quantities of BFT eggs have now been shipped to hatcheries in Israel, France and Crete from the Spanish SELFDOTT cages. Eggs are being collected on a regular basis and vary between a few thousand to 40 million on a single day. In Malta although low numbers of eggs are being collected after induction, maximum 250,000 (Sunday 3rd July) probably due to the strong currents in the shallow cages, already numerous hatching experiments are being tried and for the first time copepod suplementation will be in use with support from Norwegian collegues (SINTEF), another first for the SELFDOTT project. In the last year of the project we hope that the constant supply of eggs will enable multiple trials to take place. The commercial partners involved n the work , the Fuentes group from Spain, Malta Fish Farms and the Skretting group all have played an important role so far in the development of what will be a truly sustainable aquaculture of Bluefing Tuna.
The SELFDOTT tuna cage in Spain has begun to supply a steady stream of eggs to the IEO facility and the other SELFDOTT hatcheries around the world. The first sign of eggs was spotted around the 9th of June and to date over 24 million eggs have already been released within 7 days, with a maximum so far of 16 million eggs on one day.
Third generation spawning of Atlantic bonito is obtained
The Atlantic bonito broodstock (Sarda sarda) at the marine culture plant in Mazarrón belonging to the Murcian Oceanographic Centre of the Spanish Institute of Oceanography (IEO) have begun to spawn viable eggs spontaneously, and researchers are rearing the third generation of individuals born in captivity .
Clean Seas Complete their Spawning Season:
Successful transfer of fingerlings to seas cages.
Some broodstock were lost and a number of structures have been damaged including cages etc even though the facilities are over 800km from the earthquake epi centre. The focus now is to re-establish the facilities.
Japanese Researchers almost complete whole Pacific Bluefin Tuna Genome (see article)
Successful Coordination meeting held in Montpellie at UM2. European researchers make plans for the next BFT spawning season. Further scientific meetings to be held at the EAS meeting in Rhodes in October and a Stakeholder meeting to in November 2011
Last fingerlings from 2010 spawning die in SELFDOTT facility in Mazarron Spain at approximately 120 DPHProceedings of "The 40th Anniversary of Pacific Bluefin Tuna Aquaculture "Towards the Sustainable Aquaculture of Bluefin Tuna" held in Amami (Japan) on 15th October can be found under publications:

SPAWNING IN 2010
The 2010 spawning season has started with spontaneous spawning in Spanish Broodstock for the first time and limited induced spawning in Malta Brood stock. In the ALLOTUNA project in Bari 20 million eggs were collected in 1 day. In Spain 11 million eggs were collected on 1 day from 2 cages.
Article Published on Bonito Spawning
5 years ago, my colleague and friend Aurelio Ortega (Yeyo) had a dream: to achieve the domestication of Atlantic bonito (Sarda sarda).As you know, after some very promising trials in the period 2005-2007, we have decided to include it in the SELFDOTT project as the bonito is an scombrid, and it could be consider as a model for the bluefin tuna culture.Last year, after a wise and hard work carried out by Yeyo and also by our technician Javier Viguri, a few bonitos born in captivity in our facilities survived...Last Friday evening-night these bonitos have spawned. So, as the SELFDOTT coordinator is for me a pleasure to announce that...for the first time in the world...
WE HAVE OFFICIALLY CLOSED THE LIFE CYCLE OF THE ATLANTIC BONITO (Sarda sarda).
We will keep you updated about more news related to this very important event.

Tuna eggs ID through simple test kit available within hours:
One of the major concerns pelagic egg identification of Tuna when they spawn has now been solved with a rapid, simple test with in a few hours with a proprietary gel-electrophoresis system which enables protein fingerprinting. Further developments of the SELFDOTT partners UNIDUS, MFF and MRRA and have enabled both atlantic BFT to be distinguished from all other Tuna species and also individual females and male within hours using molecular techniques. This breakthrough will enable a much tighter control on individual species (CITES) relevant and also controlled husbandry of induced spawning and egg quality for sustainable tuna aquaculture.
Example of comparison between BFT, Amberjacks and Sea Bream eggs.
CITES ban could have severe consequences for Dommestication Research !.
Whilst welcoming most attempts to protect dwindling BFT tuna stocks the present proposal being considered in Dohar may have serious consequences for future Domestication Research. It is difficult to foresee how the research work, which has been supported by the logistics and capital investment of numerous Fish Farmers can continue if these are no longer commercially viable. How the proposed close liason with CITES and ICCAT should work in the future if no commercial fishery exists for BFT remains unknown. Too date BFT farming is one of the most closely controlled aspects of BFT management and the SELFDOTT project has also been rigourously controlled. Domestication of this species is possible as shown by our Japanese colleagues and for European scientist it is only a matter of time. Successful spawning in captivity has been possible from 2005 and last years successes in Spain (138 million eggs) show that larval rearing is now the bottle neck to overcome. One would think a CITES ban should stimulate research into domestication but it may have the opposite effect.
