Abstract

The Cyprinidae family usually live in peat waters and have high tolerance to various water quality conditions. This study aims to determine the morphological characters of fish from the Cyprinidae in the Peat Waters of Parit Nanas, North Pontianak District, Pontianak City. The research was conducted from October to December 2021 at five stations and four replicates were conducted. The results found 4 species and 489 individuals consisting of D. rhomboocellatus (271 individuals), D. trifasciatus (63 individuals), O. melanopleura (4 individuals), and O. spilurus (151 individuals). The longest body size was owned by O. melanopleura, which ranged from 152.1-250.1 mm, while the smallest was D. rhomboocellatus which ranged from 23.2-51.9 mm. The morphological characters of each species of fish found can be distinguished from the differences in mouth structure, size, color, and body pattern.
