Less highly prized by some who feel bluefin is the best, nonetheless there are some who swear that yellowfin tuna is the best eating overall. :dribble:

Natural History

Yellowfin tuna are powerful swimmers, built for endurance and speed. To help conserve energy on its long-distance journeys, a tuna’s body is almost perfectly streamlined, reducing drag around its fins. And a tuna can retract those fins so water flows more smoothly over its body. This makes the tuna super-streamlined.

Unlike most fish, tuna are warm-blooded and can heat their bodies up to 6° C (43° F) warmer than the surrounding water. This added warmth helps a tuna’s muscles work faster and more efficiently. Tuna consume as much as 5% of their body weight daily and must continually swim with their mouths open to force water over their gills, supercharging their blood-rich muscles with oxygen.

Yellowfin tuna prefer tropical temperatures, so the only time they visit the outer bay is when strong El Niño currents bring warm water to Monterey Bay. They look similar to bluefin tuna, except for longer and wider pectoralhttp://www.montereybayaquarium.org/images/shared/icon_glossary_brown.gif (http://javascript<b></b>:openGlossary('pectoral')) fins and a long second dorsalhttp://www.montereybayaquarium.org/images/shared/icon_glossary_brown.gif (http://javascript<b></b>:openGlossary('dorsal')) fin.

Conservation

Yellowfin tuna mature and reproduce very quickly and seem to have a healthy population size, but there are problems with how they’re caught.

A staple of the tuna canning industry, yellowfin tuna are sought by purse seine and longlining fleets worldwide. Purse seines catch tons of unwanted fish and other animals, called bycatchhttp://www.montereybayaquarium.org/images/shared/icon_glossary_brown.gif (http://javascript<b></b>:openGlossary('bycatch')). Longlineshttp://www.montereybayaquarium.org/images/shared/icon_glossary_brown.gif (http://javascript<b></b>:openGlossary('longlining')) kill a large number of endangered sea turtles every year.

When buying yellowfin tuna, ask for U.S. troll-caught, pole-caught or handline-caught; these are environmentally friendly fishing techniques. Visit the Seafood Watch section (http://www.montereybayaquarium.org/cr/seafoodwatch.asp) on our web site to learn more about choosing seafood wisely.

Cool Facts

A 200-pound yellowfin tuna can swim steadily at 23 miles per hour.
Light-colored, vertical bars appear on the sides of yellowfin tuna while they’re feeding.
Magnetite, a mineral found in neural pits in the tuna’s snout, may be used by the tuna to detect the earth’s magnetic field for navigation.





I love those heart videos, dark! The guys in the 2nd set are punks, either you're going to eat it or not, don't eat half and then puke or spit it out! They should have brought Mommy along on the trip to hold their hands.

:waaah:
