Why they could not fertilize tuna's eggs like the way they do with salmon by squeezing the eggs out of a female and squeezing the male sperms into the eggs! You just need bigger hands for bigger fishes! Voila!
-
is it sustainable?
-
THIS is the source of the problem here 03:29 for Tuna and many many other issues.
-
A bit misleading, tuna farming already exists and has been for a decade at Kinki University in Japan. The trouble is the quality of the fish and the economics of it.
-
Don't believe the hype, typical BBC misinformation. I've seen what the fishing is like in Port LIncoln and the bit they did get right is the fact there are a lot of millionaires there and guess how they maintain that wealth? Not farming that's for sure! Just stop buying Tuna and stop the slaughter.
-
I say we duke Japan again but this time bigger and that'll save 3/4 of the world's tuna population.
-
OR stop supplying mercury laden tuna to fish sellers.... OR sink the boats that catch tuna, or they will be extinct
-
i love simons work
however it seems stupid if it requires
20 inputs for one output
stupid -
Yeah and to produce 1 kg of tuna you need 20 kg kg wild fish. Wild tuna is still better.
-
there are plenty of fish in the sea I'm not buying your fish decline story . just say your in it for the money i would have more respect for you
-
Is it Legal to raise bluefin tuna as pet?
-
Gonna make myself a tuna sandwitch now
-
Great work.
-
By the way, it is wrong that world population increases. It doesn´t any longer. Search on Hans Rosling and demographics and you´ll see.

Tuna are magnificent fish and are actually warmblooded like we humans. They´re clearly overfished and even though they are trying to breed them, it is extremely difficult. Tuna are pelagic fish and as they state, not much is known about their behaviour. What we do know is that catches and size decline. I don´t eat any tuna at all, even though I love it. Make your choice - save the tuna or eat it?
-
Whoa, that's impressive, because I had no idea tuna was so difficult to breed.
-
in conclusion humans are A-holes and tuna is delicious
-
At least 25 times the size.
-
This is so wrong in so many ways. That tank needs to be at least 25 times the size..
