Abstract

The threat of extinction for bilih fish is caused by uncontrolled fishing with various types of non-selective fishing gear. dependence of fishing communities on bilih fish and there is no community-based bilih fish conservation area. This study aims to examine the various types of gillnet mesh sizes used in catching Bilih fish at Singkarak Lake, west Sumatera. Research data collection used three mesh sizes, namely gillnet mesh size 5/8 inch, 3/4 inch, and 1 inch in four villages, namely Nagari Guguak Malalo and Nagari Batu Taba (South Batipuah District, Tanah Datar Regency) and Nagari Muaro Paninggahan and Muaro Pingai (Junjung Sirih District, Solok Regency). The results showed that Bilih fish caught with gillnet mesh size of 5/8 inches had an average length of 6.680 cm and an average weight of 2.652 grams, and Bilih fish caught with gillnet mesh size 3/4 inches with an average length of 7.594 cm. and an average weight of 4.112 g, while the number of fish caught with gillnet mesh size 1 inch with an average length of 9.460 cm and an average weight of 8.200 g.

Abstract

This study aimed to analyze the structure of the mangrove community including the identification of species, density, frequency, dominance, important value index, and mangrove basal area on Kapo-Kapo Island, Mandeh Region, Pesisir Selatan Regency. Mangrove community structure data collection was carried out by direct observation, starting with data collection and identification of species, number of individuals and diameter of mangrove tree. In collecting data on the structure of the mangrove community, water quality measurements were also carried out pH, salinity, temperature and looking at the substrate of the mangrove. Based on the results of the study, identified species of mangrove in Kapo-Kapo Island, Mandeh Region, Pesisir Selatan Regency, namely R. apiculata, S. casseolaris, and L. littorea. The average values of KR, FR, DR and INP on tree-level mangroves at R. apiculata were 97.00%, 65.00%, 93.02%, and 255.03%. S. casseolaris 1.82%, 28.33%, 6.14%, and 36.29%. L. littorea 1.18%, 6.67%, 0.84%, and 8.68%. The species R. apiculata had the highest Important Value Index from the tree level of the most dominating species on each transect.Keywords: Kapo-Kapo Island; mangrove; structure of the mangrove community
