Sports fishing net tips

GILL NETS

A gill net is a special kind of sports costa rica fishing net comprising a long length of fibre (cotton or nylon etc.) meshes. It may be set on the sea bottom, surface or mid water and is usually left overnight.

It may be anchored or free floating. To be effective, a net should not be detectable to the fish. The bottom of the net is generally weighted while the top is supported by floats

A fish, swimming into the net, can only pass part way through before becoming trapped. the twine of the net should have enough elasticity to allow the fish to swim through the mesh until it is firmly caught.  As the fish struggles to free itself, it becomes "gilled" as it can not move or try to escape According to the desired size of fish, the mesh size is varied. Fish with a smaller girth than that of the mesh opening are able to swim through. A large mesh size, e.g. 230mm to 300mm, can be used for larger fish, such as sharks or tuna, and a small mesh size, e.g. 153mm to 178mm, can be used for smaller fish. The way the net is constructed and the depth it is set also determines the size and species of fish captured.

Gill Net Operations

Setting gill nets may involve using a marker buoy with a rope (buoyline) and anchor attached to one end of the net. These are are thrown into the sea from the stern of the boat when sports fishing take place. As the net flows out into the water, the float line and sinker line are arranged so as to ensure that the net does not tangle. The crew then hauls in the net using the float and sinker lines, removing and collecting the fish which are caught in the mesh.

Floats and Sinkers for fishing tour

The purpose of the floats in a gill net is to ensure the buoyancy of the float line (head rope) is correct. They must be strong enough to withstand heavy pressure in deep waters and must not absorb water or become entangled in the netting. Therefore, the shape, size and materials of the floats is crucial. They are usually attached directly to the float line or threaded onto it.

Sinkers (weights) are fastened to the sinker line (foot rope) and must have sufficient weight to sink the bottom part of the fishing net. They must also be smooth to ensure

Sports Fishing Buoys

Surface buoys (generally called marker buoys) should have enough buoyancy to prevent the nets from sinking even with heavy catches and be large enough to be seen from a distance.

Netting Needles

A special kind of needle (figure 4) is used for making nets by hand. It may be made of wood. For hand made nets, a mesh gauge (or mesh stick) is used to determine the mesh size and ensure uniformity. This is usually made from a piece of hard smooth wood which is either flat or rounded.

How to start Net Braiding To start net braiding (figure 7), a number of loops need to be formed, using a clove hitch, on the head rope which will be equivalent to the number of meshes required. This is known as the setting up row. When forming the setting up row the proportion of twine used for the knots is slightly more than the amount used in making the ordinary sheet bend. A smaller mesh gauge is necessary for making the initial row of loops.

Net Mending In order to repair tears, needles with either single or double twine should be used depending on the kind of net pieces to be mended and these pieces should be hung squarely so that the meshes are even. The meshes and bars made during net mending must be the same length as the original meshes of the net.

When the tear needs too much braiding to sew up the sides, the repair can be made by replacing the damaged portion of the net by a patch of netting of the same mesh size. In order to avoid complicating the work, the hole prepared should be square or rectangular, without any bars, like the patch itself. If bars are left in the hole, the patch has to have the same number, in the same places, so that they can be connected.
