Modified Purse Seine Nets

Definition: Modified purse seine nets refer to a type of fishing gear that has been adapted or altered to minimize the unintentional capture of non-target species, also known as bycatch. Bycatch refers to the incidental capture of marine organisms that are not the primary target of the fishing operation.

Reducing Bycatch of Non-Target Species

The use of modified purse seine nets offers a promising solution to mitigate the issue of bycatch in commercial fishing operations. These modified nets are designed with specific features and techniques that aim to minimize the capture of non-target species while still effectively catching the desired target species.

One common modification is the incorporation of escape panels or selective devices in the net structure. These panels allow smaller or non-target species to escape through specially designed openings, reducing their chances of being caught. By providing an exit route for non-target species, modified purse seine nets help to maintain the balance of marine ecosystems and protect vulnerable species.

Furthermore, the use of acoustic deterrent devices (ADDs) in modified purse seine nets can also contribute to reducing bycatch. ADDs emit underwater sounds that are unpleasant or disruptive to non-target species, effectively deterring them from entering the net. This technology helps to create a more targeted fishing operation, minimizing the impact on non-target species populations.

Another modification involves the use of larger mesh sizes in certain sections of the net. This allows smaller fish or non-target species to swim through the gaps, reducing their chances of being captured. By optimizing the mesh size, modified purse seine nets can selectively catch the desired target species while minimizing the capture of non-target species.

It is important to note that the effectiveness of modified purse seine nets in reducing bycatch depends on various factors, including the specific design of the gear, the fishing location, and the target species. Ongoing research and collaboration between sustainable development experts, fishing communities, and regulatory bodies are crucial to continuously improve the design and implementation of modified purse seine nets.

By adopting and promoting the use of modified purse seine nets, the fishing industry can contribute to sustainable fishing practices and the conservation of marine biodiversity. These innovative fishing gears play a vital role in minimizing the unintended consequences of fishing activities and moving towards a more environmentally responsible approach.
