Have you seen these orange objects floating in the lake this week? If you do, please do not disturb them in any way.
Powell Wheeler, Fishery Biologist for the NC Wildlife Resources Commission, explained that these are gill nets, placed to capture walleye and bass for a genetics study they are conducting. According to Wikipedia, Gillnetting is a common fishing method used by commercial and artisanal fishermen of the oceans and in some freshwater and estuary areas. Gill nets are vertical panels of netting normally set in a straight line. Fish may be caught by gill nets in 3 ways:
- Wedged: Held by the mesh around the body;
- Gilled: Held by mesh slipping behind the opercula;
- Tangled: Held by teeth, spines, maxillaries, or other protrusions without the body penetrating the mesh.
Gillnets are so effective that their use is closely monitored and regulated by fisheries management and enforcement agencies. Mesh size, twine strength, as well as net length and depth are all closely regulated to reduce bycatch of non-target species. Gillnets have a high degree of size selectivity.
Friends of Lake Glenville is so fortunate to have the NC Wildlife maintaining an active presence on our beautiful lake, and keeping us informed of their activities!
