PHU YEN IS KNOWN AS THE BIRTHPLACE OF TUNA FISHINGPHU YEN IS KNOWN AS THE BIRTHPLACE OF TUNA FISHING
Phu Yen is the first location nationwide to begin tuna fishing, which has not only brought in a huge income to the locals, but also contributed to defending the country’s sea sovereignty. To develop off-shore fishing, the province has now a fleet of more than 600 ships of large capacity.
Tuna fishing in Phu Yen has been selected by the Government as the key fundament in the plan to develop off-shore fishing. In 2011, Phu Yen tuna was granted a trade mark “Phu Yen Tuna” by the Vietnam’s National Office of Intellectual Property, the first brand of this kind in Vietnam.
Besides fishing, Phu Yen Province has many advantages in aquatic culture with high-quality products including lobsters, flower crab, white-leg shrimp, sweet snails and grouper. The annual output can reach over 10,000 tonnes.
SKIPJACK TUNASKIPJACK TUNA
Skipjack are the smallest and most abundant of the major commercial tuna species. They have a streamlined body that is mostly without scales. Their backs are dark purple-blue and their lower sides and bellies are silver with four to six dark bands. Skipjack can live as long as eight to 10 years. They are found mainly in the tropical areas of the Atlantic, Indian and Pacific Oceans, with the greatest abundance seen near the equator.
Tonggol is a species of tuna of tropical Indo-West Pacific waters. They seem to avoid turbid waters, and form schools of varying sizes.
Longtail tunas are dark blue to black dorsally (on top), with silvery white bellies and lower sides. Colorless oval spots are arranged horizontally along their bellies. Their second dorsal and anal fins have yellow hues, while their caudal (tail) fins are blackish with yellow-green streaks. Their second dorsal fins are higher than their first, and their pectoral fins are short to moderately long in size. Max size and weight recorded is 145 cm and 35.9 kg respectively, while their common length is about 70 cm.
FRIGATE MACKARELFRIGATE MACKAREL
The frigate mackerel has a very slender body shape with two well-separated dorsal fins, short pectoral fins, and an anal fin followed by seven finlets. Its coloration is dark bluish above with a white belly. This species of mackerel grows to 58 cm (23 inches) and may reach 4.5 kg (10lb) in weight.
Mackerels are pelagic schooling fish, and are found worldwide in tropical and subtropical seas. Mackerels, as well as tunas, may be observed along rocky shores and over patch reefs as well as in offshore waters. The black skipjack tuna, Euthynnus lineatus, form schools in coastal waters and near offshore reefs. It is very similar to a frigate mackerel, but with a less slender shape and a narrower space between the dorsal fins.
