Poreissa

Poreissa is a term that can refer to several things, primarily related to fishing nets and the materials used in their construction. In a general context, it often describes the mesh or netting material itself. This netting is typically made from strong, durable fibers, traditionally natural materials like hemp or cotton, but increasingly from synthetic polymers such as nylon or polyethylene due to their enhanced strength, resistance to rot, and longevity.

The size of the mesh, or "pore," in a fishing net is a critical factor determining its effectiveness and selectivity. Smaller mesh sizes can catch smaller fish, while larger mesh sizes are designed to allow smaller fish to escape, thus acting as a form of conservation by letting juvenile fish grow and reproduce. Regulations in many regions specify minimum mesh sizes for different types of fishing gear to manage fish stocks sustainably.

Beyond the basic netting, "poreissa" can also refer to specific components or types of fishing nets. For instance, it might describe the treated or strengthened edges of a net, the knots that hold the mesh together, or even a particular type of net construction used for specific fishing purposes. The term's precise meaning can sometimes depend on local dialect or the specific fishing tradition being discussed. Understanding the characteristics of the poreissa, including its material, mesh size, and construction, is fundamental to comprehending fishing techniques and their environmental impact.
