For instance, the National Oceanic and Atmospheric Administration (NOAA) advises using mesh sizes that prevent overfishing.
-
Vertical Configuration: Gillnets can be set vertically in the water. They often extend from the surface to the seabed, capturing fish swimming in any direction. This vertical setup increases capture rates for pelagic (open water) and demersal (near the bottom) fish species.
-
Set and Drift Types: Gillnets can be set stationary or allowed to drift with the current. Stationary gillnets, referred to as set gillnets, are anchored to the seabed. Drift gillnets move with marine currents, making them effective for catching highly migratory fish such as tuna. According to a study by O’Farrell et al. (2018), drift gillnets can yield significant catches but also raise concerns about bycatch, which refers to unintended species caught in the nets.
-
Bycatch Reduction Devices: Many commercial fisheries incorporate bycatch reduction devices, such as excluder panels. These panels allow non-target species to escape, helping sustain fish populations. Research conducted by the Pew Charitable Trusts (2019) found that implementing these devices can decrease bycatch in gillnet fisheries by over 30%.
-
Regulation and Monitoring: Gillnet fishing is subject to various regulations to minimize environmental impacts. These regulations include limits on fishing seasons, mesh size requirements, and maximum catch limits. Regulatory practices, such as the use of vessel monitoring systems (VMS), help enforce compliance and track fishing activities. This is crucial for maintaining sustainable fish stocks in accordance with guidelines set forth by organizations like the Food and Agriculture Organization (FAO).
Overall, gillnets are a versatile fishing method, but their efficiency comes with the responsibility of managing bycatch and ensuring that fish populations remain stable and sustainable.
