Fishing Activities and Catch Diversity in the Swamp Waters of Bangkau Village, Hulu Sungai Selatan Regency

Abstract Bangkau Village is one of the swamp areas with significant potential as a fish producer in South Kalimantan. This study aimed to identify the types of fishing gear used during the rainy season, determine the composition and proportion of the catches, and analyze the diversity, uniformity, and dominance indices. The experimental fishing method involved testing fishing operations using the fishing gear found in Bangkau Village, with sampling conducted at each location three times, one week apart. The results revealed that the fishing gear used included tempirai kawat, hancau, lalangit, pangilar , and sesuduk . Ten fish species were caught, with the following proportions: Trichopodus trichopterus 4.38%, Trichogaster pectoralis 28.19%, Helostoma temminckii 1.77%, Anabas testudineus 13.75%, Belontia hasselti 0.90%, Channa lucius 0.009%, Betta picta 1.17%, Dermogenys megarrhamphus 0.23%, Clarias batrachus 2.03%, and Monopterus albus 2.52%. The diversity index was 1.07, which falls under the medium category, the uniformity index was 0.47, indicating a small population with depressed communities, and the dominance index was 0.5, signifying unstable community dominance, meaning certain species dominated others.
