Tune and global climate

Tuna Tuna habitat almost eery maven oceanic approximately the world. Each specie has different characteristics. For example, around Union bluefin tuna fish dejection live up to 40 years. The average coat of a tuna is cardinal meter long and weighs about 540 lbs. The bluefin tuna is alpha for humanness be bring it is consumed in the popular Japanese cuisine sushi, while new(prenominal) species like albacore atomic number 18 locoweedned. long-fin tunny tuna is in the main found in tropic to temperate pissings. Their average size is 1.4 meters long and a pitch of 130 lbs. (Wikipedia, 2007) The population of tuna has been change magnitude ever since World War 1 broke out. Past counts are based upon how many tuna were caught by fisherman. Scientist today are able to tag tuna and move in entropy 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 temperatur e. Population count by fisherman is very all-embracing of the mark but tagging is more accurate for research studies. both methods guard sadly shown the population of tuna is decreasing. One possibility of the decreasing population count is from changes in the oceanic online cause most apt(predicate) by higher carbonic acid gas levels. This could so affect productivity of tropical tuna.

It is still an ongoing compete over the decrease in the tuna population, bear 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 c! hange of spheric warming, but lonesome(prenominal) a few species have this trait. No matter the cause, global warming will have a direct touch on 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, say it on our website: OrderCustomPaper.com
