World Tuna Day is celebrated every year on 2 May. Tuna Day does not provoke eating more tuna fish rather allures attention to this valuable species threatened by a stunning demand for their meat, mostly in the form of canned tuna and sushi (a dish of tuna fish in Japan).
Tuna is a delectable fish. Tunas are splendid creatures, with torpedo-shaped bodies that are ideal for speedy swimming, the bluefin tuna can travel up to 45 mph, dive 4000 feet and their age is up to 40 years. Pacific bluefin tuna become mature between the age of 3 to 5 years, at this age their size is about 4 to 6 feet long. The largest tuna caught so for has a size of 9.8 feet and weight is 990 lbs.
Adult female tuna of average size can spawn about 5 million eggs yearly. The length of female tuna affects her fertility and an eight feet lengthy tuna can spawn 25 million eggs yearly.
Mostly tuna species are warm-blooded, they can jump high out of water. They travel in huge schools, yellowfin tuna are fiercely loyal to their schools. Tuna has been known to team up with dolphins for protection against sharks. Pacific Bluefin Tuna breed in Western Pacific waters and migrate to Eastern Pacific waters. This creates a challenging situation to protect such a high leveling migratory species.
