The Atlantic bluefin tuna is one of the largest and fastest fish in the world. Atlantic tuna are built for speed; they can reach speeds up to 50 mph. Atlantic tuna have very large appetite, the average size of an Atlantic tuna is 6.5 feet and they usually weigh around 550 pounds. The largest Atlantic bluefin tuna ever caught was caught in Nova Scotia and weighed 1,496 pounds. Atlantic tuna are a gray and silver colour on their underside and then a dark blueish colour on the topside, this helps them with camouflage because from under them it looks like they are part of the sky and the dark blue from a top view makes them look like part of the dark water. Atlantic bluefin tuna is also very delicious, so tuna have been affected by over-fishing and that has lowered the population to drop critically low. Tuna positively affects humans because we use them for food and sport, tuna are huge and you don’t need a lot of them to have a large amount of meat and that’s one of the main reasons humans like to eat tuna. Atlantic tuna have been eaten by humans for along time, but in the 1970s the demand for tuna went up so commercial fishing operations found a new way to catch them. The way fishing industries caught fish was with fleets of giant ships with huge nets to catch large amounts of fish; this act of over-fishing almost caused this species of fish to go extinct. Atlantic tuna are also affected by many other problems, such as acidification and ocean debris. Tuna are affected by acidification because smaller animals that tuna rely on as food die because of acidification. If there is not enough food for tuna to eat then bigger predators that rely on tuna as food will starve, ways we can stop this from happening include; banning offshore drilling and conserving energy. Atlantic tuna are affected by ocean debris because when commercial fishing boats drop their nets in the ocean sometimes when they are done with the net they will just leave it in the ocean, this results in...
