Which Primitive Fishing Methods Work Best in Saltwater?

Choosing the Right Materials

When it comes to building a primitive fishing net for saltwater, the choice of materials is crucial. For a gill net, a monofilament mesh with a gauge of 3.5 to 4.5 mm (0.14 to 0.18 in) and a mesh size of 10 to 15 inches (25 to 38 cm) is ideal. For a seine net, a nylon mesh with a gauge of 5 to 6 mm (0.2 to 0.24 in) and a mesh size of 12 to 18 inches (30 to 46 cm) works best. The mesh should also be resistant to abrasion from coral and other underwater obstacles.

Building a Gill Net

To build a gill net, start by cutting four equal lengths of netting, which will form the four sides of the net. Tie the top and bottom edges of the netting together with a sturdy knot, leaving a 2-foot (60 cm) opening at each corner. Attach a float line to the top edge of the net, spaced 2 to 3 feet (60 to 90 cm) apart, and a lead line to the bottom edge, spaced 3 to 4 feet (90 to 120 cm) apart. This will allow the net to sit flat on the surface of the water and sink to the correct depth.

Setting Up a Seine Net

To set up a seine net, start by marking out a circular area of the seafloor with a radius of 20 to 30 feet (6 to 9 meters). Tie the bottom edge of the net to a stake or anchor, and then attach a rope to the top edge of the net. Pull the rope tight to form a circle, and then slowly move the net in a circular motion, scooping up fish in the center of the circle. This method is particularly effective for catching large schools of fish.
