But they have two types of gill structures.

Here, in a photo by Brian, a seemingly crucified shark is caught up in a gill net off of Baja.

But this one morning I jumped in and found this thresher that had just recently died in the gill net.

But what they can't deal with is anthropogenic stresses, human things, like this picture that shows a leatherback caught at night in a gill net.

Mr. Gill (India) At the outset, please allow me to express our deep appreciation to the President of the General Assembly for his introductory remarks.

Mr. Gill (India) said that there was currently a wider recognition than in the past of the need for fundamental equality between women and men.

The negative impact of abandoned fishing nets, especially gill nets on coral reefs, is tremendous and has been recorded in the region (State of the Marine Environment Report, 2003).

The author further argues that the Regulations give priority to fishing by way of angling and that traditional fishing methods (gill netting, spearing, bait fish traps, seines, dip nets etc) are restricted.

Likewise, commercial fishing frequently depends on gill nets walls of fine netting in which fish become snared, often by the gills. They may suffocate in the net, because, with their gills constricted, they cannot breathe.

These factors include restrictions on trawl fishing from 1991 followed by its total prohibition in 1993 the imposition of seasonal restrictions on fishing of certain commercially important species and the standardization of gill net mesh size for various species.
