Quick Answer
Gill nets tend to catch larger fish species such as sturgeon, salmon, and cod, which often become entangled in the net's mesh. Fish with a more streamlined body shape, such as tuna and mackerel, are less likely to get stuck. Fish with a smaller girth, like trout and panfish, can easily slip through the mesh.
Types of Fish Caught in Gill Nets
Gill nets are a common type of fishing net that uses a horizontal panel of netting to catch fish. The mesh size of a gill net can vary, but it typically ranges from 2 to 6 inches (5 to 15 cm) in size. Fish with a larger mouth size, such as sturgeon, are more likely to get caught in gill nets with a mesh size of 4-6 inches (10-15 cm).
Construction and Materials
Primitive fishing nets, including gill nets, were made from natural fibers such as cotton, jute, or hemp. The mesh size and construction of the net were often determined by the intended catch. A dip net, on the other hand, is a smaller, handheld net used for catching fish in shallow water. Seine nets, which are larger and more complex, are used for catching larger schools of fish. When constructing a gill net, it’s essential to use a suitable mesh size and material to ensure effective catching and minimizing bycatch.
Avoiding Bycatch and Damage
To reduce the risk of bycatch and damage to the net, it’s crucial to use a mesh size that is suitable for the intended catch. A mesh size that is too large may allow smaller fish to escape, while a mesh size that is too small may cause damage to the net. In addition, using a gill net with a lead line, which is a weighted line that runs along the bottom of the net, can help to prevent the net from drifting and reduce the risk of bycatch.
