SAN DIEGO-( )-South Pacific Tuna Corporation (SPTC) announced today that is selling more than half of its 14 U.S.-flagged purse seine fishing vessels to foreign operators, reducing its fleet to six by the end of the year. Approximately 12 U.S.
Captains and their crew will be relieved of duty. Additionally, the San Diego-based office and management team will be reduced to support the downsized fleet.The sale of the vessels represents a reduction of 70,000 tons of US-produced tuna, which will increase the U.S. Seafood trade deficit by $80M to $100M USD annually. The move also reduces the volume of sustainable FAD-free, MSC certified fish for the global tuna market, including fish supplied under the Pacifical program. SPTC will continue to supply sustainably harvested tuna to its current customers with its remaining operations.“Our fleet reduction is due in part to the U.S. Government’s continued lack of support and the lack of interest in ratifying the,” said SPTC Executive Director J. Douglas Hines.
“Despite our efforts to work with the Trump Administration, the National Marine Fisheries Service (NMFS) has not reciprocated and continues its overly aggressive compliance and enforcement actions.”NOAA compliance authorities have made it virtually impossible for the U.S. Distant water tuna fleet to compete against the fleets from China, Korea and Taiwan. Unlike foreign competitors who are strongly supported by their governments, the U.S.

Fleet faces policies by its own government that are non-supportive and essentially anti-industry and anti-trade.With the withdrawal of the U.S. Fleet from the Western Pacific, the United States’ influence in those waters will continue to decline as China, Korea, and Russia take a larger role in the region.“In the global priorities of the U.S. Government, the Western Pacific has become an afterthought,” said Hines. “But as Pres.
Ronald Reagan recognized in 1988, the South Pacific Tuna Treaty is a critical step to ensuring American vessels and commerce continue to lead in the region and the world. The reduction of the U.S.
Fleet will be a devastating blow for the international policy community as well as the Western Pacific sustainable fishery ecosystem.”“It is a sad day for us all after fighting all these years as we see the end of long legacy of Tuna harvesting by U.S. Interest,” Hines added. “However, we leave with pride of years of fighting to improve the region.”SPTC will continue to evaluate the opportunities and challenges for its remaining U.S.-flagged purse seine operations as it continues to operate the balance of its fleet, but with guarded hope.About SoPacTunaSouth Pacific Tuna Corporation (SPTC) is a United States-based tuna vessel management company headquartered in San Diego, California.

Thunnus thynnus orientalis(Temminck and Schlegel, 1844)The Pacific bluefin tuna ( Thunnus orientalis) is a species of found widely in the northern, but it is and also recorded as a visitor to the south Pacific.In the past it was often included in, the 'combined' species then known as the northern bluefin tuna (when treated as separate, T. Thynnus is called the ). It may reach as much as 3 m (9.8 ft) in length and 450 kg (990 lb) in weight.Like the closely related Atlantic bluefin and, the Pacific bluefin is a commercially valuable species and several thousand tonnes are caught each year, making it.
It is considered threatened by the. 's program have placed all bluefin tunas on the 'Avoid' list, and they are also placed on the 'Red List' by and the. Contents.Distribution The Pacific bluefin tuna is primarily found in the, ranging from the coast to the western coast of North America. It is mainly a species found in oceans, but it also ranges into the tropics and more coastal regions. It typically occurs from the surface to 200 m (660 ft), but has been recorded as deep as 550 m (1,800 ft).It in the northwestern (e.g., off, and ) and in the. Some of these to the East Pacific and return to the spawning grounds after a few years.
It has been recorded more locally as a visitor to the, including off Australia, and.The species is considered to consist of only one stock. Physiology. This section needs additional citations for. Unsourced material may be challenged and removed.Find sources: – ( December 2011) Thermoregulation Almost all fish are cold-blooded. However, tuna and are: they can regulate their body temperature. Warm-blooded fish possess organs near their called that consist of a series of minute parallel veins and arteries that supply and drain the muscles. As the warmer blood in the veins returns to the for fresh oxygen it comes into close contact with cold, newly oxygenated blood in the arteries.
The system acts as a counter-current heat exchanger and the heat from the blood in the veins is given up to the colder arterial blood rather than being lost at the gills. The net effect is less heat loss through the gills. Fish from warmer water elevate their temperature a few degrees whereas those from cold water may raise it as much as 20 °C (36 °F) warmer than the surrounding sea.The tuna's ability to maintain body temperature has several definite advantages over other sea life. It need not limit its range according to water temperature, nor is it dominated by climatic changes.
The additional heat supplied to the muscles is also advantageous because of the resulting extra power and speed. Bluefin tuna have been clocked in excess of 30 miles per hour (48 km/h) during 10 to 20 second sprints, enabling it to hunt, etc., that slower predators cannot capture.Life cycle Pacific bluefin tunas reach maturity at about 5 years of age, the generation length is estimated at 7–9 years and based on two separate sources the is 15 years or 26 years. At maturity it is about 1.5 m (4 ft 11 in) long and weighs about 60 kg (130 lb). Individuals that are 2 m (6 ft 7 in) long are regularly seen, and the maximum reported is 3 m (9.8 ft) in length and 450 kg (990 lb) in weight. Elsewhere, a mass of up to 550 kg (1,210 lb) has been reported for the species.
According to the, the all-tackle game fish record was a 411.6 kg (907 lb) individual (Donna Pascoe) caught on 19 February 2014 onboard charter boat Gladiator during the National Tournament.Spawning occurs from April to August, but the exact timing depends on the region: Early in the northwest (the southern part of its breeding range) and late in the (the northern part of its breeding range). Large females can carry more eggs than small ones, and between 5 million and 25 million eggs have been reported.Pacific bluefins eat various small schooling and fishes, but have also been recorded taking animals,. Human interaction Commercial fishery. Pacific bluefin caught near in 1913Pacific bluefin tuna support a large.Aquaculture Japan is both the biggest consumer and the leader in tuna farming research. Of Japan first successfully farmed already-hatched bluefin tuna in 1979. In 2002, they succeeded in breeding them, and in 2007, the process was repeated for a third generation. This farm-raised tuna is now known as Kindai tuna.
Kindai is a contraction of Kinki University (Kinki daigaku). Conservation Unlike the other bluefins ( and ), the Pacific bluefin tuna was not considered threatened initially, resulting in a rating in 2011.
In 2014, it was found to be threatened and the status was upgraded to. Is occurring in the Pacific bluefin, but overall the stock was not yet believed to be in an overfished condition in 2011.According to stock assessments completed in 2011, 2014 and 2016 by the International Scientific Committee for Tuna and Tuna-Like Species in the North Pacific Ocean (ISC), the present-day population is at just 2.6 percent of its historic levels. The overall fishing mortality rate for this species remains up to three times higher than is sustainable.In 2010, it was estimated that the complete spawning was 40–60% of the historically observed spawning biomass.
In 2000–2004, between 16,000 tonnes and 29,000 tonnes were caught per year.Its wide range and migratory behavior lead to some problems, since fisheries in the species are managed by several different that sometimes give conflicting advice. The IUCN have recommended that the responsibility is moved to a single organisation. Other recommendations include a substantial reduction of fishing of this species, especially juveniles. As much as 90% of the caught Pacific bluefins are juveniles.' S program have placed all bluefin tunas on the 'Avoid' list, and they are also placed on the 'Red List' by both and the. Mercury levels.

A exists in other tuna species.Cuisine About 80% of the Pacific and are consumed in Japan, and tunas that are particularly suited for and can reach very high prices. In Japan, some foods made available for the first time of the year are considered good luck, especially bluefin tuna.
Winning these new year auctions is often used as a way to get publicity, which raises the prices considerably higher than their usual market value: on 5 January 2013, a 489-pound (222 kg) Pacific bluefin tuna caught off northeastern Japan was sold in the first auction of the year at the in for a record 155.4 million (US$1.76 million) – leading to record of US$3,603 per pound, or ¥703,167 per kilogram. A 618-pound (280 kg) pacific bluefin tuna sold for 333.6 million yen (US$3.1 million) at a Tokyo fish market on 5 January 2019. The price equates to roughly $5,000 a pound, more than double the previous record.
The fish was caught off Oma in northern Japan. References. ^ Collette, B.; Fox, W.; Juan Jorda, M.; Nelson, R.; Pollard, D.; Suzuki, N. 2014: e.T16749.:. Retrieved 9 December 2012. ^ AsiaPacific-FishWatch (2017). AsiaPacific-FishWatch.
