Bluefin Tuna

Bluefin tuna

In a recent study executed by SINTEF Fisheries and Aquaculture (Norway) valuable results, on Bluefin Tuna growth and survival rates, were obtained. Eggs were transported from a fish farm in Spain and hatched into larvae that were offered different stages of copepods.

The growth and survival data from this experiment were significantly better than what has been achieved in the reference hatchery where larvae were offered rotifers and Artemia. A bone-development and skeletal analysis was conducted and significant differences were observed. Larvae fed rotifers and Artemia had high frequencies of deformities in the jaws, tail fin and the vertebral column, whereas these abnormalities were far less frequent in the larvae fed copepods.
