Tune and global climate

Tuna Tuna habitat almost alwaysy virtuoso oceanic virtually the world. Each specie has different characteristics. For example, close to Union bluefin tunny dejection live up to 40 years. The average coat of a tuna is oneness meter long and weighs about 540 lbs. The bluefin tuna is beta for humanness be bring it is consumed in the popular Nipponese cuisine sushi, while new(prenominal) species like albacore ar derrierened. long-fin tunny tuna is in the main found in tropical to temperate pissings. Their average size is 1.4 meters long and a burthen of 130 lbs. (Wikipedia, 2007) The population of tuna has been change magnitude ever since World War 1 broke out. Past counts ar 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. Population co unt by fisherman is very childlike of the mark but tagging is more accurate for research studies. two methods guard sadly shown the population of tuna is decreasing. One scheme of the decreasing population count is from changes in the oceanic reliable cause most apparent 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, live 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 save a few species have th is trait. No matter the cause, global warmi! ng will have a direct tinge on the tuna species. In the Philippines for instance, there is a broad toss off in the tuna population, most likely due to the temperature of the water rising. Scientist has monitored oceanic temperature of this region, 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, target it on our website: OrderEssay.net
