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

Abstract

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.

Wiritasi ve Sarang Tiung (Endonezya)’da Sabit Kaldırma Ağı Balıkçılığının Karşılaştırmalı Çalışması

Abstract

Bu çalışma, Endonezya’nın Güney Kalimantan bölgesinde yer alan iki balıkçı köyünde—Wiritasi (Tanah Bumbu) ve Sarang Tiung (Kotabaru)—sabit kaldırma ağı (fixed lift net) balıkçılığının yapısal ve operasyonel özelliklerini karşılaştırmaktadır. Ağ yapısı ve balıkçılık faaliyetlerini belgelemek amacıyla arazi gözlemleri ve nitel görüşmeler gerçekleştirilmiş; av kompozisyonunu analiz etmek için nicel av verileri toplanmıştır. Bulgular, iki saha arasında kullanılan malzemeler, birim çaba başına av (CPUE) ve av verimliliği açısından belirgin farklılıklar olduğunu ortaya koymuştur. Wiritasi’de bambu ve aniung ağacı gibi daha hafif malzemeler kullanım kolaylığı ve verimlilik sağlarken, Sarang Tiung’da daha derin sularda dayanıklılığı artırmak amacıyla mangrov kerestesi tercih edilmiştir. Wiritasi’de ortalama CPUE (12,83 kg/çekim), Sarang Tiung’a (8,46 kg/çekim) kıyasla daha yüksek bulunmuş ve bu fark bağımsız örneklemler t-testi sonucuna göre istatistiksel olarak anlamlıdır (p < 0,05). Av kompozisyonu da sahalar arasında farklılık göstermiş olup, başlıca küçük pelajik türler olan Sardinella fimbriata, Selaroides leptolepis ve Stolephorus sp. baskın türler olarak belirlenmiştir. Bu bulgular birlikte değerlendirildiğinde, enerji tüketimi ile av optimizasyonu arasında olası bir denge (trade-off) bulunduğuna işaret etmekte ve küçük ölçekli kaldırma ağı balıkçılığında maliyet-etkin aydınlatma stratejilerinin önemini vurgulamaktadır. Sarang Tiung’da LED lambaların kullanımı ekonomik avantajlar ve çevresel hususları öne çıkarırken, Wiritasi’de kullanılan cıva lambaları sürdürülebilir bir geçiş ihtiyacını ortaya koymaktadır. Ayrıca yerel balıkçılar için temel yönetim ve uygulama önerileri de tartışılmaktadır.
