pyydysjärjestelmä

Pyydysjärjestelmä, often translated as trapping system or fishing gear system, refers to the complete set of equipment and methods used for capturing fish or other aquatic animals. This encompasses not just the primary catching device, such as a net or trap, but also all associated components like ropes, floats, weights, buoys, and anchoring mechanisms. The design and implementation of a pyydysjärjestelmä are heavily influenced by the target species, the aquatic environment, and the fishing regulations in place.

Different types of fishing gears form the core of these systems. For example, a gillnet system would include the net itself, which is designed to entangle fish by their gills, along with floats to keep it buoyant and weights to sink it. A fyke net system, used in shallower waters, consists of a series of funnel-shaped nets designed to guide fish into a central chamber, requiring poles for support and anchors to hold it in position. Pots or traps, often used for crustaceans, are sturdy structures that allow entry but prevent escape, requiring lines and buoys for retrieval.

The selection and proper deployment of a pyydysjärjestelmä are crucial for efficient and sustainable fishing. Factors such as water depth, currents, seabed type, and the behavior of the target species all play a role in determining the most effective system. Furthermore, modern pyydysjärjestelmät may incorporate technological advancements, such as GPS tracking for deployment and electronic monitoring systems. The responsible use of these systems aims to minimize bycatch and environmental impact.
