Most of the turtles, sharks, tunas and whales are way down in numbers.

And if it's tunas you don't care about, perhaps you might be interested that international long lines and pursing chase down tunas and bycatch animals such as leatherbacks, sharks, marlin, albatross.

Sole, snoek and tuna occur on the continental shelf along the coastline.

Three tunas tagged.

The tuna team from TOPP has done the unthinkable three teams tagged 1,700 tunas, bluefin, yellowfin and albacore all at the same time carefully rehearsed tagging programs in which we go out, pick up juvenile tunas, put in the tags that actually have the sensors, stick out the tuna and then let them go.

We bring the tuna out, we measure it.

That is where the tuna spawn.

This was a harpoon gun... he was, er, skindiving.

These tuna swim the entire ocean.

Black alligator.

Earlier this year, the U.S. warned that albacore and bigeye tuna, also caught with longlines, are being overfished in the Pacific.

Recent studies have documented the rapid decline of large predatory fish species such as billfish, sharks and tuna.

And every single day these tuna, bluefin like this, are stacked up like cordwood, just warehouse after warehouse.

We've actually tagged 1,100 tunas.

Living amongst our tunas our North American tunas are European tunas that go back to the Med.

So we can save the bluefin tuna.

I loaded it with soot, hang it!

They're the largest of the tunas, the second largest fish in the sea bony fish.

There is especially high demand in foreign markets for tuna, shark, lobster and shrimp.

Its economy depends on the tuna fish canning industry.

There was tuna salad sandwiches and egg salad sandwiches and salmon salad sandwiches.

Much of the fish is tuna transhipped from the South Pacific region on its way to the U.S. market.

We've actually taken a sliver of the ocean, put it behind glass, and we together have put bluefin tuna and yellowfin tuna on display.

Bluefin are pursued wherever they go there is a gold rush on Earth, and this is a gold rush for bluefin.

As awareness grows, levels of consumption of large predatory fish such as tuna and swordfish are dropping.

The high seas, where whales, tuna and dolphins travel the largest, least protected, ecosystem on Earth, filled with luminous creatures, living in dark waters that average two miles deep.

The advisory also included a caveat that women should eat no more than 12 ounces of light tuna a week and no more than six ounces a week of white tuna.

Of the 32 demersal, pelagic and shellfish fisheries studied, the Central Pacific swordfish tuna longline fishery had the fourth highest fuel use intensity (liters of fuel per ton of catch), and the tuna billfish longline fishery had the highest exceeding even that of shrimp trawling, the second highest.

So the key now is to make it behave like tuna.

Bluefin are warmblooded like us.

Bluefin have two populations one large, one small.

Swing into the alley, bam! This torpedo cuts loose with a.38.

The distribution and relative abundance of many pelagic fisheries resources such as tuna, squid, sardines and anchovies were related to surface oceanographic conditions.
