Sampling gill nets, monofilament, multifilament, trammel, flag gill nets.

Construction - These nets most commonly have 4 or 5 panels with varying mesh sizes, although Sterling has manufactured sampling nets with as many as fifteen net panels. Our standard nets are made of five net panels each with a different mesh size. Each panel is 25' long. All panels are incorporated into one net which is 125' long. Nets are six or eight feet deep.
As standard construction, these nets will be furnished with either a 3/8" or 1/2" diameter braided float line, with the foam enclosed in the braided line. The float line varies with depth, twine construction and special fishing conditions. The lead line is a lead core with soft nylon braided shell, extremely flexible and will not snake when stored. Diameters vary with net use from 1/8" up to 3/8" diameter. A SINKING STYLE NET WILL BE SUPPLIED UNLESS OTHERWISE SPECIFIED. The overall construction makes the net tangle free. No leads or floats will fall through the meshes and snarl the net. The net is ready to fish.

Twine and Mesh Sizes - Mesh sizes range from 1/2" square up to 6" square. The sizes are usually in combinations of 1/4" gradations. Sterling, however, can offer any combination of mesh sizes that may be required. The sequence of the net panels is normally in order of the mesh sizes, but sometimes the smallest mesh is in the middle fanning out to the larger sizes on both ends. The smaller mesh panels are made of lighter twines, Nos. 46, 69, and 104 and the larger mesh sizes are heavier twine, Nos. 139 and 209.

Sterling can supply vertical sampling gill nets, either multifilament or monofilament, that are commonly used to determine the vertical fish distributions of bodies of water.

Construction Design - There is no common design of this type of gear because of the individual parameters of the water being investigated. There are however, several standards in the selection of the net.

Sampling Panels - The sampling panels used take either of two forms. The vertical net can be one solid mesh panel, usually ten to fifty feet wide, equipped with floats and leads and one mesh size. The other variation is a series of vertical panels, usually about eight feet wide and varying in mesh size, joined together. These nets usually do not have floats and leads but are supplied with a 3/16" solid braided nylon cord all around the net. Users generally rig their own flotation bar and spreader bar connected to the edge of the nets to eliminate the problem of the nets bowing in at the midpoints and lead line. The "lead line" is sometimes a weighted tube or pipe that also insures proper bottom width.

Depth Stretched Monofilament - Sterling takes special care in the construction of it's monofilament vertical sampling nets. Because most nets are net vertically hung, but are fished horizontally, Monofilament gill netting is depth stretched when manufactured. The mesh diamonds are elongated in a vertical direction and conform to the normal girth of the fish. When Sterling hangs its vertical gill nets it does not turn the depth stretched netting on its side, up and down, which would cause the diamonds to be horizontally elongated. Sterling hangs its vertical nets by joining one depth stretched panel on top of another, keeping the meshes vertical. This problem is not encountered with the multifilament gill nets because of the net's flexible characteristics.

Pricing - Vertical sampling gill nets are generally custom built to sample a specific marine environment. Sterling will gladly assist you in the design. Please contact us for prices stating water depth, intended use and specific requirements.
