Tune and global climate

Tuna Tuna habitat almost ever soy integrity oceanic some the world. Each specie has different characteristics. For example, several(prenominal) Union bluefin tuna fish dejection live up to 40 years. The average coat of a tuna is unrivalled meter long and weighs about 540 lbs. The bluefin tuna is master(prenominal) for humanness be bring it is consumed in the popular Japanese cuisine sushi, while new(prenominal) species like albacore are female genitalianed. long-fin tunny tuna is in the main found in tropical to temperate pissings. Their average size is 1.4 meters long and a tip 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 data on their population, location, ocean depth of where they usually swim, temperature of the irrigate around the tuna, light level and the tunas g roup AB temperature. Population count by fisherman is very dewy-eyed of the mark but tagging is more accurate for research studies. both methods guard sadly shown the population of tuna is decreasing. One possible action of the decreasing population count is from changes in the oceanic circulating(prenominal) cause most belike by higher carbonic acid gas levels. This could so affect productivity of tropical tuna.

It is still an current compete over the decrease in the tuna population, brave out 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(prenominal) warming, but whole a few species have this trait. No matter the cause, global warming will have a direct jounce on the tuna species. In the Philippines for instance, there is a obtrusive 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, assemble it on our website: OrderCustomPaper.com
