Abstract

Dogamit Swamp is one of the swamps in the Merauke Wasur National Park, which stores an abundant diversity of fish and biota. This study aims to examine the diversity of fish species in the waters of Rawa Dogamit. The research was conducted from July to August. The method of data collection was by determining 3 locations of observation stations, at each station an identification of all species and their environmental factors was then linked to the Diversity index, Abundance Index, Evenness Index, and Dominance. The results obtained from the study are that there are 15 species of fish, which have the highest abundance of Betik (Anabas testudineus) by 35.74% and the lowest is the Moon Fish (Megalops cyprinoides) by 0.05%. Measurement of the Diversity index is categorized as moderate, whereas for the Evenness index is categorized high at stations I and II, while station III is categorized as moderate. For the measurement of the Dominance Index, it is categorized as low or not dominant. It was concluded that there was a significant relationship between the diversity, evenness and dominance index with environmental parameters both for the survival of fish in Rawa Dogamit waters.Key Words: Diversity; Fish; Dogamit Swamp

Abstract

Climbing perch (Anabas testudineus Bloch, 1792), one of the types of fish that is able to survive in freshwater and brackish water, which belongs to the type of Blackwater fish. The study aims to determine the reproduction of Climbing perch (Anabas testudineus Bloch, 1792) at Wasur Swamp. The fish sampling was conducted in May to July 2019, with catching using a mesh of gills measuring the net-size 2.5 cm. Analysis used is the genital ratio, the maturity level of gonads (TKG), the Maturity index gonads (IKG) and fecundity. The whole fish was acquired during the study amounting to 380 tails consisting of 211 males and 169 females. The genital ratio gained during the study was 1.2:1. The spawning peak for three months of observation of the female fish of TKG IV occurred in May at the I Station. The fecundity of the Climbing perch ranges from 1.984 to 73.795, at a total length range of 105–159 mm and a total weight of 28 - 84 grams.Key Words: Climbing perch; Anabas testudineus; Reproduction; Wasur Swamp
