What is a Cast Net? with pictures
Most salmon fisheries in particular have an extremely low incidence of catching non-target species. Cast nets are not common in commercial fishing, but other types of fishing with nets and traps are common. These nets are designed for use in water which is shallow and free of obstructions such as reeds, rocks, or submerged logs. To use a cast net, the fisherman throws the lightweight net out onto the water, where it spreads out and then begins to settle very rapidly, thanks to the weighted edges. As the net approaches bottom, it is pulled closed and reeled back in with a load of fish. Bottom fishing has operated for over a century on heavily fished grounds such as the North Sea and Grand Banks.
A seine is a large fishing net that hangs vertically in the water by attaching weights along the bottom edge and floats along the top. Coracle fishing is performed by two men, each seated in a coracle, plying his paddle with one hand and holding a shared net with the other. When a fish is caught, each hauls up his end of the net until the two coracles are brought to touch and the fish is secured.

A trammel is a fishing net set vertically in the water with three layers. The inner layer is of a finer mesh than the outer layers. In a controlled manner, swing the net away from the target moving both hands together, then back toward the target, releasing the net in an upward motion. When releasing the net, continue pinching the lead line in your dominant hand for a split second longer.
A mesh-like net is cast and pulled through the water. As the net moves through the currents, fish are collected inside. The net is then pulled out of the water and the entrapped fish are removed. Nets with a small mesh size catch non-marketable, undersized targeted fish, un-targeted fish as well as targeted fish. Those unwanted fish are disposed as “waste” back into the ocean.
As with any fishing equipment, the bigger the targeted catch, the bigger size of mesh and stronger netting material needed. Cast netting is very popular, either in fresh or salt water, and can be used in different applications from Sport to Commercial fishing. Many people use cast nets, from kids to experienced professional fishermen, almost everywhere in the world. You should get a “pancake” if you follow all of the steps correctly. Your backyard is a good place to try out your cast net technique until you get the hang of it.
The rope is called the ‘handline’ and has a loop on the end to secure to your wrist. The ‘horn’ is the circular plastic piece at the top, separating the ‘braille lines’ that run through the net. The weighted line at the bottom is called a ‘lead line’ which helps the net sink quickly. Are used in multiple of the fishing methods described here.
Are similar to pelagic longlines but are anchored horizontally to the seabed. This way, fish are caught that live close to the seabed. Up to 20,000 bait hooks are hanging from an up to 130 km long line. Because of its enormous by-catch rate, longline fishing is heavily critiqued. The baits that are drifting close to the surface can not only kill sharks and sea turtles but also lure many seabirds to their death.
Fixed gillnets are mostly used to catch fish in shallow water. Fishing nets have been used by people all over the world for a long time. Our stone-age ancestors may have used these nets to catch fish, and there is proof of it. Indeed, the Antrea net, which is thought to date back to 8300 BC, is the world’s oldest fishing net that has been found so far. This ancient net was made entirely out of willow branches.

He was once a highly successful director of the Zoo and Aquarium, but he has since hung up his gloves and moved on to other ventures. Dion's passion for animals began at a young age, when he would help his father care for their family pets.
