and sport anglers, Hawaii is revealing Pacific Blue Marlin with large, great fish spear-shaped from the tip of the long migration paths. electronic tags Marlins on surprising activities, including the three fish that floating Hawaii-Marquesas Islands to Mile 3 000 trips throughout the South Equator. Such trans-Equatorial migrations is unusual, i.e. researchers expect the information that I look forward to this summer, the marking of.
Pacific Blue Marlin, one of the biggest billfish to swim in the open sea are beginning to give some information about the options in this mysterious secrets. The new data is whether "and release the" anglers Hawaiian International Billfish Tournament involved in underwater journeys thanks to Marlins. they were committed to help Stanford researchers with the marking of large fish catching and releasing.
Anglers and researchers marked 10 Marlins electronic tags in August on the coast of Hawaii Big Island Hawaii this year during the tournament set Great Marlin Race off. 120 days when the Marlins will be stored in the tags, how to travel to dive deep into the water temperatures and what they encounter.

If are indications about should be interesting.The winner is, as the case may be, the farthest to the fish swims.
Marine biologist Stanford's Hopkins Marine Station Randy Kochevar "in 2009, we received some of the longest tracks which never have been found to be using electronic tags, Marlin" said. "Three of these Marlins swam as Hawaii the entire Equator-Marquesas Islands, which was something that we really did. "This is a journey of about 3 000 km (more than 1,850 miles).
Kochevar said is very unusual aquatic animals through the territory of the Equatorial move is due to a combination of high temperature surface water and oxygen poor water only below. "Equatorial region is an important limit for so many species was really surprising to see that three long songs went right for all, "he said.
"Great Marlin Race is unique in that it combines the thrill of excitement in the State-of-the-art competitive angling conservation with the investigation," said Kochevar. "By calling the charter boat captains and crews and the tournament anglers as such investigation we can learn a lot more and get a lot more people excited about the work we do. "
Two already this year, the tags have become fish, off sooner than the researchers wanted to but it is a part of transoceanic labelling and monitoring of the game.
"This is part of the challenge for tag fish," says Barbara block, Professor Charles and Elizabeth Prothro, Marine Sciences, leading research group."You have a large number of tags to return enough data."
Block, which adopted the electronic tags are in the mid-1980s on the use of competition, has made extensive studies after the tag, and is completing the 10-year mark, Pacific Predators (TOPP) program, which more than 4,300 electronic tags introduced 23 species open ocean animals in the North Pacific.
Early days of electronic encoding technology is not very developed, which could make it difficult for an unusual interpretation of results: .1980 one Tags from Marlin Found floating near the Galapagos Islands, Kochevar said.
"No one believed it comes out Marlin, which had swum fully down there," he said."They thought extension has just come and free trumpetinsoittaja."
Kochevar said last year But on the basis of the results of swimming, far Marlin idea looks much more plausible.

Anglers were given the opportunity to finance the electronic tags to enable Marlins caught and released during the tournament.
Billfish Tournament organizers offered to provide free team competition in the year following the entry into force of the tag from the farthest to the surfaces, where it was originally introduced.
Although a large Marlin Race is associated with the sponsors of the competition between the Marlins, additional information is the primary focus.
"We really do not know a lot of Marlins patterns and their operation," said Kochevar.
"It appears that instead of traveling to spawn a specific location, and then feeding, bluefin tuna, such as end-of-year expenditure it seems like they are constantly spawning and their sorting, come and go from one place to another," he said.
"What we hope to learn from this work," said Stanford marine biologist George Shillinger, "is the basic information about the history of the life of these animals, we would like to know. when they go to the feed and when they go to paritella. we want to understand how they use the ocean, the type of area and in the end, how can we manage their populations to ensure that they remain in light."
Updates will be posted regularly to the Great Marlin Race-on a site that presents the results of the 2009 race.
"Our hope," said Kochevar, "is that we can consider any other sport fishing tournaments you can create your own Great Race programs."
