TRANSDOTT Egg collection successfully completed

TRANSDOTT  Spawning Season Ends with Collection of over 40 million Eggs

A highly successful  spawning season for the captive Atlantic Bluefin Tuna Broodstock of the TRANSDOTT project has just been completed. The Team consisting of  the Malta Aquacuture Research Centre, Malta Fish Farming, IOLR/NCM and Univ. Düsseldorf have collected over 40 million eggs over a period of 4 weeks. Now the hatcheries based at Futuna Blue, ARDAG, IOLR , GMA are concentrating on Larval rearing.

Atlantic Bluefin Tuna Spawning Seasons Starts with a Bang

The TRANSDOTT broodstock in Malta under the care of Malta Fish Farming has already started to produce eggs in significant quantities. Starting on the 8th June until the 24th June  over 15,7 million eggs have already  been collected.

The TRANSDOTT partners in Israel IOLR and ARDAG have all received their first and sometimes their second shipment as with Futuna Blue in Spain. The hatchery belonging to the  Malta Aquaculture Centre and Malta Fish Farming have also been stocked with eggs. Larval rearing results so far have been positive  and 14 DPH larvae are still surviving.

Bluefin Tuna Survival may also be threatened by Ocean Acidification

In  a pilot study carried out by TRANSDOTT scientists in Malta Aquaculture  Research Centre  Bluefin Tuna eggs and larvae from captive broodstock were exposed to the simulated Oceans of  the Future (1200 ppm CO2). The first results indicated a lower hatching rate and a 10 -15% decrease in survival rate compared to control tanks with  present day CO2 levels of 390 ppm. A more in depth study is planned this year in parallel to the Tuna propagation work with other TRANSDOTT partners.

World Tuna Day May 2 2014

WORLD TUNA DAY 2014 – GOOD NEWS for Atlantic Bluefin Tuna:

The EU 7th Framework Research Project TRANSDOTT has   just received an extension for a third spawning season to cover this seasons work with its European partners:

The project which was due to end in March 2014 has received a six month extension  to enable European researchers to optimally use their extended Broodstock, now up to  50 fish with weights exceeding  120kg. These fish should be capable of delivering up to 100 million eggs  this season. The research groups based in Malta, Israel, Spain, Norway and Germany will again pool their resources to try and deliver  large quantities of Tuna fingerlings (35g+) to commercial sea cages in the Mediterranean for “growing out”. Last season’s supply only survived in Spain until December when  cold weather prohibited further growth. Similar experiments  from the IEO group in Spain, part of the  previous SELFDOTT consortia still have survivors from 2011, 2012 and 2013. In a growing international effort to protect Tuna resources   sustainable Tuna aquaculture is a key technology developing in Europe which can relieve the pressure on wild-stocks and provide closed circle aquaculture of this  valuable natural resource.  European and  International scientist are striving to conserve an important “Top Predator” using different strategies for conservation and propagation. TRANSDOTT has a role to play in transferring this technology  to applications in the  Paciifc and Indian Ocean as  done  by our Japanese colleagues.
