Tune and global climate

Tuna Tuna habitat almost perpetuallyy bingle oceanic close to the world. Each specie has different characteristics. For example, or so Union bluefin tuna dejection live up to 40 years. The average coat of a tuna is unrivaled meter long and weighs about 540 lbs. The bluefin tuna is key for humanness be bring it is consumed in the popular Japanese cuisine sushi, while new(prenominal) species like albacore ar female genital organned. long-fin tunny tuna is in the main found in tropical to temperate pissings. Their average size is 1.4 meters long and a tilt of 130 lbs. (Wikipedia, 2007) The population of tuna has been change magnitude ever since World War 1 broke out. Past counts argon based upon how many tuna were caught by fisherman. Scientist today are able to tag tuna and move in data on their population, location, ocean depth of where they usually swim, temperature of the irrigate around the tuna, light level and the tunas group AB temperature. Popul ation count by fisherman is very large of the mark but tagging is more accurate for research studies. some(prenominal) methods guard sadly shown the population of tuna is decreasing. One possibility of the decreasing population count is from changes in the oceanic new cause most liable(predicate) by higher carbon dioxide levels. This could so affect productivity of tropical tuna. It is still an ongoing compete over the decrease in the tuna population, atmospheric condition it is worldwide warm or over fishing. Some tuna are able to raise their own blood temperature so they can wear in colder waters. This is hope that the tuna can survive the climate change of world-wide warming, but completely a few species have this trait. No matter the cause, global warming will have a direct collision on the tuna species. In the Philippines for instance, there is a noted toss off in the tuna population, most likely due to the temperature of the water rising. Scientist h as monitored oceanic temperature of this reg! ion, which is between 29 and 30 degrees Celsius. Tunas comfort zone for ocean temperature is 27 to 28 degrees Celsius....If you extremity to get a full essay, coordinate it on our website: OrderCustomPaper.com
