Why is tuna different colours?!
Why is tuna different colours?
Answers:
I. There are different types of tuna, ie from different sub species such as yellow fin and blue fin.
2. Some are genuinely taken from the wild straight to the cannery or your local fishmonger.
3. Others caught in the wild are dragged behind the trawlers still in the water the keep them alive, then placed in offshore farm cages, fed with fabricated feed and growth hormones so they get real fat and heavy real quick and then taken to market or canneries. There is no efficient process yes for producing fully farmed tuna so they use this semi farmed process.
4. The colours vary for several reasons, different species, different feeds and artificila colouring in the feeds when semi- farmed, age of fish, area of capture because of various diets when in the wild.
Hope that answers your question. If you don't like what i have said please don't blame me, blame the Japanese

Is this the beginning of a joke?
Tuna is considered a "Red Meat" and has a charasteric deep, blood red color... if it is anything other than that, it may not be very fresh.
God... God... God... Please just once allow me to have the power to zap people who ask such questions....
Please... you know it makes sense... what possible reason could there be for asking such a nonesense?
the same as chicken, turkey, lamb, beef etc are all different colours duh!!
There are several reasons. First of all, there are different varieties of tuna - albacore, skipjack, yellowfin being the commonest.
Then, tuna fish have both light and dark flesh according to the part of the body it is taken from.
Next, if you get the canned kind, it may be packed in water, soybean oil, sunflower oil or olive oil, all of which can affect the colour of the fish.
