Cast Net
A cast net, also known as a throw net, is a net used for fishing. This type of net is circular, with small weights distributed around its edge. The net is cast, or thrown, by the fisher in such a manner that it spreads out while it's in the air before it sinks into the water. This mechanism makes it a highly effective tool for catching fish.
Design and Structure
The cast net is particularly noted for its simplicity and efficiency. Its design includes:
- Circular Shape: The net is typically circular, creating a wide area to trap fish.
- Weights: Weights are evenly distributed around the edge of the net. These weights help sink the net quickly to trap fish underneath.
- Lead Line: A weighted line, often called a lead line, runs along the perimeter of the net, aiding in its rapid sinking.
- Hand Line: A hand line is attached to the center of the net. This line is used to retrieve the net once it has sunk into the water.
Technique of Use
The technique for using a cast net involves:
- Folding: The net is typically folded in a specific manner before casting.
- Casting: The fisherman throws the net into the water with a spinning motion, causing the net to fully open and create a wide circle.
- Sinking: The weights cause the net to sink quickly, trapping fish inside.
- Retrieving: The hand line is used to pull the net back to the surface, closing the net around the captured fish.
Types of Fishing Nets
Fishing nets come in various types, each designed for specific fishing methods. Some notable types include:
- Seine Nets: These nets hang vertically in the water with weights at the bottom and floats at the top, used to encircle fish.
- Hand Nets: Small nets held by hand, used to scoop fish or other aquatic creatures.
- Haaf Nets: An ancient type of net used for salmon and sea trout, particularly associated with the Solway Firth.
Historical and Cultural Significance
The use of cast nets dates back to ancient times and has been depicted in various cultures. For example:
- Roman Gladiators: The retiarius, a type of gladiator, used a trident and net combination, similar to a cast net, to fight in the arena.
- Haaf Net Fishing: This traditional method is still practiced in parts of Britain, showing the enduring legacy of net fishing techniques.
