Diversity and longitudinal distribution of freshwater fish in Klawing River, Central Java, Indonesia

Abstract

Suryaningsih S, Sukmaningrum S, Simanjuntak SBI, Kusbiyanto. 2018. Diversity and longitudinal distribution of freshwater fish in Klawing River, Central Java, Indonesia. Biodiversitas 19: 85-92. The aims of this study were to evaluate the diversity and longitudinal distribution of fish in Klawing River, Purbalingga (Central Java). The survey was performed using a clustered randomsampling technique. The river was divided into upstream, midstream and downstream regions. Species diversity was measured as the number of species, and the longitudinal distribution was assessed by determining the fish species present in each of the three regions. Eighteen fish species of eleven families were identified in the Klawing River: Cyprinidae, Bagridae, Mastacembelidae, Anabantidae, Cichlidae, Channidae, Eleotrididae, Beleontinidae, Osphronemidae, Poecilidae, and Siluridae. Cyprinidae exhibited the highest number of species (six), followed by Bagridae and Cichlidae (two species each). The other families were represented by one species each. A single cluster analysis showed that the upstream population had a similarity of 78% and 50% with the midstream and downstream populations, respectively. Species and family diversities were higher in the midstream populations than in the upstream and downstream populations. This longitudinal distribution may be due to differences in environmental conditions and suggests that management of the land surrounding the Klawing River is a key factor in the conservation of freshwater fish.

Species richness and longitudinal distribution of crustaceans in the Logawa River, Banyumas, Indonesia

“…Dendrograms were obtained based on the similarity (%) matrix among the species assemblage from each sampling site and species distribution along the longitudinal gradient (IBM 2017). Longitudinal distribution was also analyzed descriptively and presented in the form of distribution patterns (Iglikowska and Namiotko 2012;Suryaningsih et al 2018).…”

The alien freshwater fish of Mount Galunggung, West Java, Indonesia

“…Galunggung was different compared to other areas. Cyprinidae has been the dominant family in general, such as in Klawing river at Central Java (Suryaningsih et al 2018), Batangtoru River, South Tapanuli, North Sumatra (Roesma et al 2016), Gangga river, India (Pathak et al 2013), and Danau Biwa, Japan (Kawanabe 1996 in Leveque et al 2008). Previously, Kottelat et al (1993) stated that Cyprinidae is a very large family of freshwater fishes found throughout the world, with the exception of Madagascar, Australia, New Zealand, and South America.…”

“…Galunggung but also Gunung Ciremai National Park and Gunung Halimun National Park. Their habitats are shallow stream, slow current water, and converted environments such as rice field or plantation (Beamish et al 2006;Suryaningsih et al 2018). This condition causes these species to pose herbivore feeding behavior with Bacillariophyceae, Chlorophyceae, Cyanophyceae and detritus as the additional diet (Aryani et al 2017;Batubara et al 2019).…”

DNA Barcoding: A Study of Guppy Fish (Poecilia reticulata) in East Java, Indonesia

“…The diversity and distribution of freshwater fish provide different data in the Java Island. Suryaningsih et al (2018) revealed that P. reticulata can be found in the upper and middle parts of the river flow. P. reticulata is easily found in various area and widespread throughout the world (Deacon et al, 2011).…”
