For example, a French fisherman caught a Bluefin tuna in Portugal in that took eight hours to bring in. This is the longest example recorded to catch a single Bluefin, but they can often take upwards of an hour or two to catch.
Although, the average size of a Bluefin tuna is around five feet in length, with an average weight of one hundred and fifty pounds. For example, the fishing of Bluefin tuna around Canada is strictly catch-and-release only.
This has been mirrored in many countries, as the conservation of Bluefin tuna is taken more and more seriously as time goes on. Although there have been some efforts to farm Bluefin tuna, it never works out as well as the wild-caught fish.
They are prized among sport fishers for their fight and speed, shooting through the water with their powerful, crescent-shaped tails up to 43 miles per hour. They can retract their dorsal and pectoral fins into slots to reduce drag. Bluefins attain their enormous size by gorging themselves almost constantly on smaller fish, crustaceans, squid, and eels. They will also filter-feed on zooplankton and other small organisms and have even been observed eating kelp.
The largest tuna ever recorded was an Atlantic bluefin caught off Nova Scotia that weighed 1, pounds. Bluefin tuna have been eaten by humans for centuries. However, in the s, demand and prices for large bluefins soared worldwide, particularly in Japan, and commercial fishing operations found new ways to find and catch these sleek giants.
As a result, bluefin stocks, especially of large, breeding-age fish, have plummeted, and international conservation efforts have led to curbs on commercial takes. Nevertheless, at least one group says illegal fishing in Europe has pushed the Atlantic bluefin populations there to the brink of extinction. All rights reserved. Common Name: Atlantic bluefin tuna. Scientific Name: Thunnus thynnus. Type: Fish. In the Pacific Ocean, maturity may be attained at about 90 cm in females and at about 97 cm fork length in males; in the Atlantic Ocean it is reached at about 94 cm in both sexes.
From March through July on the grounds located in the western and central Pacific Ocean it is assumed where the North Pacific albacore stock spawns. Albacore tuna are believed to be pelagic spawners that broadcast their gametes in open water, often near the surface, with fertilization being externally done. An estimation of female fecundity number of eggs range from 0.
The eggs are approximately 1 mm in diameter and remain buoyant by an enclosed oil droplet and develop very rapidly, with hatching occurring within 24 to 48 hours.
The assessment of the stocks of the North and South Atlantic Ocean from the same period showed them to be vulnerable and critically endangered. Also NO juvenile undersized albacore will be accepted into our products. ONLY albacore caught by setting nets on free swimming schools and which have had a full breeding life, the minimum weight which is accepted can vary per each ocean, since maturity age and size is different for albacore in each ocean.
In the exceptional case long lining is used, then special circle hooks and other special pre-cautions should be taken to avoid any by-catch of sharks, marine mammals, turtles or seabirds. Our methods have an absolute minimum by-catch, and leave the eco-system balance in tact. Independent observers on-board will assure and report that these goals are met. Through the Sustunable on-line tracing system — any buyer or consumer buying our albacore product — will be able to trace back exactly by which boat, which captain, and exactly where his yellowfin was caught and which responsible fishing method was used.
Size, Age, and Growth: The maximum length of a Skipjack tuna is about cm fork-length with a maximum weight of Reproduction: Skipjack tuna are oviparous, they spawn all year-round in the warm equatorial waters, while further away from the equator spawning season is limited to the warmer months.
Reproduction: The size of Yellowfin tuna at maturity varies by region, and could also vary between individuals found near- and offshore. Reproduction: Fishery in the pacific surface pole-and-line, and troll fishery , smaller sizes of albacore tuna sizes between 55 to 80 cm fork length predominate, while long-line fisheries will catch bigger fishes sizes between 95 to cm fork length.

The Bluefin Tuna is a warm-blooded animal with a conical head, sharpest vision, and voracious appetite. They also migrate and are identified by their white underside and metallic blue on top of their bodies, which also conceals them from above and below the water.
Sport fishermen and commercial fishers love the bluefin tuna for its meat, speed, and fighting spirit. The typical lifespan of the Atlantic Bluefin Tuna is years. Wikipedia - Atlantic Bluefin Tuna.
