Today in my Ecology of Fishes class we all had to bring a fish/invertebrate dish to share with the class. We also had to give a short presention on it. The dish that I prepared was Tuna pita pockets. I did a little bit of research to find out what species of Tuna it was(since they are all quite different), and found it to probably be the Skipjack Tuna. The reason I was able to decipher that this was the one, is from a number of things. First off the fact that it was really the only tuna species that tends to have pinkish meat was a huge clue. Secondly the fact that it is heavilly consumed in the United States was a further clue, as many Tuna species are only eaten in Japan. A third clue, was the fact that because it is the smallest tuna species, it is easy to make into chunks for canning purposes (which was what I used). These three things left me pretty certain that this was the Tuna species that I had made. one very important fact about this small Tuna (350mm long), is the fact that unlike other Tuna does not really impact Dolphins. The fact that it does not swin with Dolphins as many bigger Tuna species do almost guarantees that it be Delphin friendly (this was even on the package for the canned no name Tuna). A second interesting fact, is that this tuna is currently caught at 1.5 million metric tonnes per year and is probably the maximum that the world as an ecosystem can sustain and thus maked it a threatened species.
Some other important facts:
1) Most popular Tuna for consumption
2)Swims in upper layers of ocean
3)Highly migratory (found all over the worlds tropical waters)
4)Live on average about three years
