Tuna, tuna, tuna

Yesterday's leftover tuna salad for breakfast, tuna melts for lunch and then, tuna casserole for dinner. Before you know it, tuna is an all day thing. Aside from the fact that you can make a lot of meals from a can of tuna, people often fail to realize this is a "big league" fish that most of us can catch.
These guys certainly landed a big one!
To hook this ocean dweller, you don't necessarily need to charter a boat which may cost hundreds of dollars a day! Nor does it always require behemoth strength. Although tuna weighing in excess of 1,000 pounds have been recorded, most people are familiar with varieties that weigh around 40 pounds (19 Kg.) but, some weigh in at only around 8 pounds (3-4 Kg.) Additionally, tuna are found all over the world except for Polar regions at up to around 1,600 feet (500 meters.)
One of the biggest reasons for the tuna's wide proliferation is its adaptability. Tuna have the rare ability to actually regulate their blood temperature to a certain degree rather than being cold-blooded like most fish. Some species, such as the bluefin tuna, can raise their blood temperature through increased muscle activity. This warmth can result in an increase in activity which places an oxygen demand on their system and is partially responsible for their speed because a tuna must swim one body length per second to pass oxygen giving water over its gills.
Today's "healthy eating" lifestyle cries out for tuna consumption but, it must be remembered that tuna can also be high in mercury content because it is a predator fish and high on the food chain. None the less, it must also be remembered that tuna is high in Omega-3 fatty acids and protein.
As with most salt water fish, squid is always a good bait for tuna but they also respond to herring, bluefish, mackerel, cod, or whiting.

Until next time--watch yourself and watch your line!

Did you know that Starkist Tuna is a part of Heinz? I found that out when I went to the Heinz History Center a couple of weeks ago. Sadly, there are no "Sorry, Charlie" vids on YouTube!
