The stern deployment method is particularly advantageous in rough seas, as it reduces the risk of the net becoming entangled or damaged. Stern trawlers are widely used in modern fishing operations. They are known for their efficiency and suitability for large-scale fishing operations. The design of stern trawlers often incorporates advanced technologies, such as powerful winches and electronic monitoring systems, to enhance fishing performance and operational safety.

Purse Seiners: Encircling the Catch

Purse seiners are designed to encircle schools of fish with a large net, effectively creating a temporary enclosure from which the fish cannot escape. This method is particularly effective for catching schooling fish, such as tuna, sardines, and anchovies. The technique involves deploying a long net around the school of fish and then closing the bottom of the net, creating a purse-like structure. The fish are then hauled aboard the boat. Purse seiners are a crucial part of the fishing industry, particularly in regions where schooling fish are abundant. The efficient catch rates of purse seiners make them highly productive. However, the environmental impact of purse seining requires careful consideration and management to minimize bycatch and habitat damage.

• The Purse Seining Process: The deployment of the net is a highly coordinated process. The boat circles the school of fish, ensuring the net is properly positioned to encircle the targeted species. Once the circle is complete, the bottom of the net is closed, preventing the fish from escaping. The net is then drawn in, concentrating the fish towards the center, where they are eventually hauled aboard the vessel. This technique relies on the ability of the crew to locate and track the fish schools accurately. They also need to expertly handle the large nets. The successful use of purse seining requires experience, skill, and appropriate equipment.

• Advantages of Purse Seining: Purse seining can be a highly efficient fishing method. It often results in large catches in a relatively short period. The method is particularly effective for catching schooling fish, making it a valuable tool for commercial fisheries. The selectivity of purse seining can be improved through careful target species identification and deployment techniques. Purse seining can be less damaging to the seabed compared to some other fishing methods.
