gromnet

A gromnet is a type of fishing net designed for use in deep-sea fishing, particularly for catching large pelagic fish such as tuna and swordfish. The term "gromnet" is a portmanteau of "grommet" and "net," referring to the grommets used to attach the net to the fishing vessel. Gromnets are typically made of strong, durable materials such as nylon or polyester, and are designed to withstand the high pressures and harsh conditions of deep-sea environments.

Gromnets are characterized by their large mesh size, which allows for the capture of large fish while minimizing bycatch of smaller species. They are usually circular or rectangular in shape, with a weighted line attached to the center to keep the net open and prevent it from collapsing under water pressure. The net is deployed from a fishing vessel using a large winch, and is then towed behind the vessel at a specific depth.

Gromnets are an important tool in commercial and recreational deep-sea fishing, providing a sustainable and efficient method for catching large pelagic fish. However, their use has also raised concerns about the impact on marine ecosystems, particularly the potential for bycatch and the disruption of fish populations. As a result, there has been a growing focus on developing more selective fishing gear and implementing sustainable fishing practices to minimize the environmental impact of gromnet fishing.
