How is Drag Net Fishing Performed?
Introduction: Drag net fishing is a fishing method that involves dragging a large net through the water to catch fish. It is a common technique used in commercial and recreational fishing operations. This article explains the step-by-step process involved in drag net fishing:
Process:
- Boat Preparation: The fishing vessel is equipped with a winch, outriggers, and a net. The winch is connected to the net and used to drag it through the water.
- Net Deployment: The net is deployed from the boat into the water. The outriggers help spread the net out to maximize its coverage area.
- Dragging: The boat moves forward, dragging the net through the water. The speed and depth of the drag are controlled to target the desired species.
- Hauling: Once the net has been dragged for a sufficient distance, it is hauled back onto the boat using the winch.
- Sorting: The fish caught in the net are sorted and separated by species, size, and quality.
Advantages and Disadvantages:
Drag net fishing has several advantages, including its efficiency, ability to catch large quantities of fish, and effectiveness in shallow waters. However, it can also have negative impacts on the environment, such as bycatch and habitat damage.
