Blue fin tuna almost extinct?

Question

I just saw a news report on how Japan is fished the blue fin tuna to almost extinction. The report said that blue fin tuna is as important to Japan as cattle are to the US.

In the US we raise and feed the cattle.

So why doesn't Japan start raising tuna? Instead of just stealing them from the ocean? shouldn't the free ride end some time? Or is it better to let Japan just kill of the blue fin tuna forever?

Answer 1

Tuna typically weigh over 400 pounds each and grow up to 14 feet long... take a look in Google Images and you will see that they are VERY big fish. They eat a lot and need lots of room, very hard to farm.

You can farm fish up to about the size of salmon. After that it becomes impractical and uneconomical.

Fish are in decline all around the world. Even here in North America, the cod stock has dropped to dangerous levels numerous times in the past few decades.

The only real solution is to stop fishing them for a while and let the population naturally get back to it's normal size. Unfortunately people don't want to do this because companies lose lots of money and fishermen lose their livelihood entirely. Even if it is made illegal, people will still want it. If people are willing to pay for it, there always be poachers who break the law to kill animals, whether it is hunting elephants for ivory or just catching fish for food.

Answer 2

Blufin tuna both northern and southern are in severe decline.  The problem is that they are highly migratory and its thought that the entire stock of the worlds oceans could be one meaning that all the fish in the world potentially can be caught in all waters throughout the globe.  Because they cross international boundaries or EEZ's they are suseptable to fishing from all fleets.  It is a species that requires a global quota not just a reagional one because fish in the US EEZ will swim on to Japan and Australia and get hit multiple times.  There is some farming of Tuna but is is still from wild capture seed stock thus not solving any problems and most fish sold in Japan are high value wild caught fish not low value farmed fish.  Fish farmed in South Australia are large but ugly due to scaring from cages hence the low price.  Like on most issues like Tuna ie whale hunting in the Pacific they will deny till the end what effect they are having on the viability of stocks.
