Long-liners

long-liner

A long-liner returns to its homeport of Belford. Long-lining is a very labor-intensive operation, and the asymmetrical hull design, high on one side and low on the other, affords the crew some protection from the weather. Gear is also stored along the high wall, and recovered, along with the catch, along the low wall.

Long-lining is an ancient form of fishing in which multiple baited hooks are attached with leaders to a long backbone line, which is suspended at a targeted depth from buoys, and either anchored or allowed to drift. This targets surface-feeding fishes such as Swordfish. Long-lines may also be set deep to target bottom-feeding fishes such as cod. Commercial long-line fishing in the North Atlantic began in the early 1960s. The lines may be 15 miles long or more.

Long-lining is a fairly indiscriminate method that catches whatever takes the bait, and the bycatch is significant. In the last few decades, the long-line fishing industry has grown tremendously, with large boats putting out miles of line in search of sharks and swordfish, both of which are now greatly reduced in numbers. The Andrea Gail of The Perfect Storm was a Gloucester "Sword Boat, " but many such vessels are also based right here in New Jersey and Long Island. New Jersey boats are more likely to be after sharks than swordfish.

Swordfish

Sword fishermen routinely discarded thousands of sharks as bycatch, most of which were dead already, and the rest killed before they could be safely handled. When swordfish became scarce, the long-liners began targeting the sharks themselves instead. Now sharks are scarce.

A monstrous variation on long-lining is drift netting, practiced mainly in the Pacific by far-eastern fishing fleets. Huge floating nets, sometimes hundreds of miles long, are set out to ensnare anything that comes along. There is no such thing as bycatch to a drift-netter - tuna, sharks, squid, seals, dolphins, turtles, whales - everything goes into the freezer. When such a net is lost, it goes on killing until it eventually sinks under the weight of all the rotting sea life it has captured. Drift netting is largely banned, but some countries pay little heed to international law, and far out at sea where no one is watching ...

Having said all that about doubles, there are still times when it makes more sense to dive "lite". Out of the water, double tanks are very heavy and cumbersome, which makes them practical only for boat entries, where you simply have to stagger across the deck and fall overboard. At other times, and in less deep situations, you can maintain a safe redundant air supply using a much lighter "pony bottle" - a small tank of 20-40 cubic feet, weighing only about 10-20 lbs, with its own regulator that is used only in an emergency. Some of the situations where this configuration is useful to include medium-depth dives, 40-80 ft, training and practice dives ( especially in the quarry, where it is possible to reach quite deep water from the shore ), and excursions to the tropics.

Larger pony bottles ( 40-50 cf ) are also useful as "swing bottles" for carrying special decompression mixes, while the smaller ones are small enough to actually take with you when you travel. Most airlines will allow it in checked baggage if you remove the valve. This is very useful since many tropical destinations are not equipped to provide the kind of safety equipment that we take for granted here. The smallest pony bottles are really not big enough to get you out of trouble on a deep Jersey dive, however.
