Atlantic Bluefin Tuna
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 many ocean animals (such as tuna) to be caught in the net and die.
It is now more important than ever for people to do what the politicians failed to do – stop consuming bluefin tuna,” Dr. Tudela, Head of Fisheries at WWF Mediterranean Atlantic bluefin tuna are mainly found in the western Atlantic, but they are also found around Newfoundland and the Gulf of Mexico. Tuna usually live in the open ocean, but they can be seen jumping out of the water catching small fish. Tuna mostly live in groups; schools of tuna can be found feeding, just hanging out or migrating thousands of miles across the Atlantic.
Atlantic tuna faces many problems such as the ones I previously wrote about, but if we want to put a stop to those problems we need to find a solution. One of the things we can do is make fishing seasons, if the government was to make a certain time when it was okay to fish for tuna and then once the season was over fishermen couldn’t fish for tuna anymore. I think that that is a pretty good plan but we would have to do more than that, for example they could ban tuna fishing for a year or a designated time duration and then check to see if the tuna population increases.
Ocean debris and Acidification is also a problem, the way to stop that is not very hard, people just need to take the initiative to stop dumping harmful chemicals, non-organic waste material, ect. “After overwhelming scientific justification and growing political support in past months – with backing from the majority of catch quota holders on both sides of the Atlantic – it is scandalous that governments did not even get the chance to engage in meaningful debate about the international trade ban proposal for Atlantic bluefin tuna,” –Dr. Sergi Tudela, Head of Fisheries at WWF Mediterranean
