Last week there was a show on Discovery about cod fishing in the
Bering Sea and that was one of the issues for the fishermen - when the
whales show up, they have to pull in the long lines and leave because
they will lose half their catch to the whales.

Longliners go for large fish. They put out fifty miles of line with a
hook every two hundred feet. You put it out and haul it back once a
day. Swordfish and tuna are longlined. Maybe halibut. Not cod, which
are netted. They would find cod suitable for bait. As for whales, the
sonar they have will pick them up miles away. They can sit there and
watch while the whales clean the longline.

What about sharks? They must view the fish caught on long lines as a
chow line. I wonder how often when pulling in those lines, the fishermen
encounter a large shark caught on the line and maybe really mad.

They all carry a shotgun just for that. No live sharks on board. Some
sharks are commercial fish, of course.

Have you watched the show on Discovery where the Aussies go out in the
ocean and set up these huge holding pens for Tuna that they are
catching with other boats? Amazing! Great Whites break into the nets
to get to the fish, and divers go down to get the Great White out and
repair the nets!

Many of the sharks I've encountered leave the fish's head on the hook.
And when they do eat the whole fish, they simultaneously bite through
the line like a hot knife through butter. All the shark fishing rigs
I know of use a long length of steel leader. Is steel what a long line
is made of??

The longliner I looked at had fifty miles of 700 lb mono, and the
leaders were mono as well, as far as I know: there were none in
evidence when I looked at the boat.

Fishermen lay out long sets of lines across the ocean floor. These
sets are made up of skates, long lines with baited hooks attached to
them. These sets can run nearly 3 miles in length and hold as many as
4000 or more hooks
