These nets can be set at various depths and are effective for catching a wide range of fish species. In Bangladesh, gill nets are used extensively in both rivers and coastal waters. The mesh size of gill nets is carefully selected to target specific fish species, minimizing the capture of non-target species. Fishermen often use different types of gill nets depending on the season and the availability of fish. Gill nets can be set and left unattended for several hours, allowing fishermen to pursue other activities while the nets are fishing. However, this practice also requires careful monitoring to prevent the nets from becoming overloaded or damaged. The use of gill nets is regulated in some areas to prevent overfishing and protect vulnerable species. Fishermen must obtain licenses and adhere to specific guidelines to ensure sustainable fishing practices. The effectiveness of gill nets depends on the water conditions, such as clarity and current, as well as the behavior of the target fish. Fishermen often adjust their techniques based on these factors to maximize their catch. The economic importance of gill net fishing is significant, providing livelihoods for many coastal communities in Bangladesh. The fish caught using gill nets are sold in local markets and contribute to the food security of the region. Proper maintenance and repair of gill nets are essential to ensure their longevity and effectiveness, with fishermen often spending considerable time mending tears and reinforcing weak points. The traditional knowledge and skills associated with gill net fishing are passed down through generations, preserving this important cultural heritage.
Sustainable Net Fishing Practices
