Surrogate sushi: Japan uses biotech for bluefin tuna

I hope he succeeds. I love Otoro.

Dr. Moreau would have been proud of him.

Love that comment Cleo! :D

This is one possibility for farming these fish, but why has it taken until the fish is damn near extinct until they start to take it seriously? This technology has been around for decades and has been used in many fisheries for a long time. It's also been documented that, the Japanese, who consume over 90% of the world's fresh tuna, are not interested in eating farmed tuna. The only way for all tuna populations to recover is to ban fishing, which is not gonna happen. Even reduced quotas is not answer cos the fish stocks are already at an unsustainable level. There has also been suggestions of banning the fishing of certain species of tuna, but that will only put pressure on the stocks of other species of tuna. If tuna fishing was banned today it would take at least twenty years for some of the species to recover. However, scientists believe that, the populations of other species of tuna (like blue fin) may never recover.

Disillusioned

Lots of crock science you write there. Give us some data to prove them. For you information it only takes three years for a small fry to become a mature species to give off-springs based on studies at Kinki University and any where from 0.01% to 0.1 % succeeds in become mature from 100,000 eggs born. That's 10 to 100 mature fish after three years from a single pair alone per year and reproduce for at least 5 years. How many pairs do you think there is in the wild at the moment?

In captivity the success rate in maturing goes up by 10 to 30 folds at the moment. That is why they can ship out 2000 tonnes per year.

good news i guess but sure to be some downside also - like we see with salmon farrming and the prolifeation of diseases that spread to the wild population.

@Kearimashita - ... prolifeation of diseases that spread to the wild population ...

If these are caused by virus or bacteria to which their farmed siblings are immune, it is likely the wild fish will eventually also develop immunity, especially if they interbreed.

An immediate ban on all Blue Fin fishing is needed. Without the tuna, the oceans will be filled with jellyfish. The economy will be hit hard but this is a better alternative to having no Blue Fin at all.
