Comparative Study of the Fixed Lift Net Fisheries in Wiritasi and Sarang Tiung, Indonesia

This study compares the structural and operational characteristics of the fixed lift net fisheries in two fishing villages: Wiritasi (Tanah Bumbu) and Sarang Tiung (Kotabaru) in South Kalimantan, Indonesia. Field observations and qualitative interviews were conducted to document gear construction and fishing operations, while quantitative catch data were collected to analyze catch composition. The results revealed notable differences in material selection, CPUE, and catch composition between two sites. Wiritasi used lighter materials like bamboo and aniung wood for ease and efficiency, while Sarang Tiung’s gear incorporated mangrove timber for durability in deeper waters. Wiritasi exhibited a higher mean CPUE (12.83 kg/haul) than Sarang Tiung (8.46 kg/haul), with the difference being statistically significant based on an independent samples t-test (p < 0.05). Catch composition also differed between sites and was dominated by small pelagic species, particularly Sardinella fimbriata, Selaroides leptolepis, and Stolephorus sp. Collectively, these findings are consistent with a possible trade-off between energy consumption and catch optimization, underscoring the relevance of cost-effective lighting strategies in small-scale lift-net fisheries. The use of LED lamps in Sarang Tiung highlights economic benefits and environmental considerations, while Wiritasi’s mercury lamps demonstrate the need for sustainable transition. The key recommendations for local fishermen are also discussed.
