COMPOSITION OF TYPES OF FISH THAT IS CAPTURED WITH THE GILL NETS IN KUMBE RIVER, MALIND DISTRICT, MERAUKE REGENCY

The purpose of this study was to determine the composition of the species of fish caught with gill nets on the Kumbe River in Merauke Regency. Fish sampling is carried out in July - September 2017 at three observation stations which are fishing areas by local fishermen, including: station I in the estuary section; station II ± 1500 meters from the estuary and station III ± 3000 meters from the mouth of the Kumbe River. The fishing gear used is gill nets with mesh sizes: 3.5, 4 and 7 inches. Fish samples obtained were then calculated according to the number per species and were identified at the Aquatic Resource Management Laboratory of the Faculty of Agriculture, Musamus University. Biological parameters observed were species composition, species richness, diversity index (H '), evenness index (E) and dominance index (D). The results of this research are species composition: Cinetodus crassilabris namely 41.48% and the most and the lowest is Megalops cyprinoides and Nibea squamosal namely 0.25%. There are 22 species of wealth. Moderate diversity and evenness index, dominance index close to 0 indicates that there are no dominant fish on the three research stations.
