Abstract

Uceng (Nemacheilus fasciatus) is relatively common fish in Indonesia. Characteristics of this are small and slender bodied with a line marking on the lateral part of its body. This species is distributed in Java and Sumatra. There are differences on geographical conditions such as water levels, water currents and the environment in each distribution area of this species. These differences may result in both morphology and genetic variations. This study aimed to determine morphological variations of uceng fish among populations from three different regions of rivers in Java, namely Cijeruk River in Bogor, Progo River in Temanggung and Lekso River in Blitar; and to compare its morphological variations between populations from those three difference regions. Methods used in this study was purposive sampling to collect samples, meristic and morphometric data acquisition, furthermore those data were analyzed using kruskall-Walis to test significant difference between each morphological characteristic, Mann-Whitney to determine the differences between populations and finally PCA data analysis to determine distributional patterns between each populations. Result showed significant morphological differences (p<0.005) between populations from three different rivers and there were differences in several morphometric and meristic characteristics between each populations.    Key words: morphological variations; Nemacheilus fasciatus; Bogor; Temanggung; Blitar

Abstract

Softshell turtles are freshwater turtles with soft carapaces. Their habitat includes freshwater bodies such as rivers and swamps in tropical and subtropical regions. Data on softshell turtle species and their potential habitats in the freshwater ecosystems of the Special Region of Yogyakarta have not been well documented. Based on information from local residents, a softshell turtle population occurs in Sidorejo Village, Lendah, Kulon Progo, Special Region of Yogyakarta. Accordingly, this study aimed to examine the species and potential habitat of softshell turtles in Sidorejo Village, Lendah, Kulon Progo, Special Region of Yogyakarta. Sampling was conducted from 2 February to 17 April 2020 in Kedung Ingas Stream, Sidorejo Stream, and Andong Stream using the Purposive Sampling method. The results showed that the softshell turtle species found was Amyda cartilaginea. The habitat was characterized by shallow streams with depths of 20–70 cm and widths of 150–250 cm, muddy substrates with leaf litter, clear water available throughout the year, calm currents, and riparian vegetation with canopy cover such as water apple, guava, gayam, thorny bamboo, apus bamboo, and lempeni. Softshell turtle nests were characterized by their location under trees, fragments of crab shell in front of the nest cavity, small bubbles in front of the cavity, nest forms resembling cavities in soil or solid rock, and isolated nest sites. These three streams are potential habitats for softshell turtles.
