Fish Traps

Well, it's that time of year again, time to renew the web hosting. And for those of you that don't know, that has become a lot more expensive than it used to be. Fifty dollars a year is now several hundred. Not to mention the price of domain names has gone up ten-fold.

And I just found out that the nice folks at PayPal disabled all my Support buttons, and I never got a notice (although that may be my fault.) In any case, it is all working again now, so if you would like to make a small donation to help defray these costs, it would be greatly appreciated.

fish trap
A fixed fish trap. The curtain nets stretch from surface to bottom, and the fish are funneled into holding areas.

Fish traps are only practical in shallow water. They have the advantage of keeping both the targeted catch and the bycatch alive ( unless a shark gets in ! ) You can still see a few fish traps in use in Raritan Bay, where they are built around fixed pilings rather than buoys and anchors as shown here. In years past, shore-based trawling or "haul seining" was also practiced in the bay, where a net would be deployed off the beach by a small boat, and drawn in by donkeys or trucks.

Haul Seining

An estimated 50 tons of spawning Striped Bass is taken in a single net on a Virginia beach in 1972. This type of fishing would be completely illegal today.

The main fishery in Raritan Bay has always been Mossbunker.

A similar type of fixed fish trap is the gill net, which uses a specific-size mesh to trap a certain size of fish. When the fish tries to swim through the net, only its head fits. Then when it tries to back away, it becomes ensnared by its gill covers. This kind of gill netting is fairly specific, as smaller fish pass through the net unharmed, and bigger ones don't get caught in the mesh. A terrible variation of this is drift-netting, described above.
