Abstract

The characteristics of habitat will affect the survival of organisms in an ecosystem including for suckermouth armored catfish Pterygoplichthys pardalis in Ciliwung River Indonesia. There is still no information that explains the suitable habitats for feeding, spawning and breeding sites of P. pardalis in the Ciliwung. The purpose of this study is to identify the habitat characteristics for feeding, spawning, and growing of P. pardalis in the Ciliwung. The results shows that the characteristics of the feeding habitats for P. pardalis in Ciliwung includes; temperatures of 28oC-29oC, light intensity of 1,12-7,74 Klux, depth of 50–148 cm, turbidity of 18,13–42,39 FTU, current velocity 0,4-2,1 m/s, BOD5 3,8-5,7 mg/l, pH 6,5-6,9 with a phosphate value of 0,05-0,1 ppm and ammonia 0,6 to 4,6 ppm. The characteristics of spawning habitats around P. pardalis’ nesting burrows are at temperatures 27,9–28,3ºC, DO 6,3–6,7 mg/L, pH 6,5–7,5 with a TDS value of 0,098-0,222 mg/L, the turbidity of 6,80-18,88 FTU and substrate measuring of 0.062-0.004 mm in the form of mud particles. The type of vegetation that is often found in the Eupatorium triplinerve (IVI = 0,469), Cynodon dactylon (IVI = 0,550) and Pennisetum purpureum (IVI = 0,236).
