Ekomorfologi Udang Galah (Macrobrachium Rosenbergii) Di Sungai Kampar Bagian Provinsi Riau

Abstract
Water quality in the upstream and the downstream of the Kampar River is diferent due to pollution. However, Macrobrachium rosenbergii can be found in those areas. The condition of the water may affect the morphological characteristics of the prawn. To understand the morphological differences of the prawn, a study has been conducted in February - April 2022. Samplings were conducted three times, once/ 2 weeks, using traps and fishing rods. The prawn data were analyzed using a Kruskall Wallis and Mann Whitney tests. Seven parameters of the aquatic environment and nineteen morphological characteristics of the prawn were studied. Carapace length (CL) was used as a reference. Results shown that in the upstream, water temperature was 29-300C, brightness 38.5-42.5cm, pH 7, DO 4.12-4.86 mg/L, CO2 4.99-5.99 mg/L, BOD5 4.12-
4.82 mg/L, hardness 120.0-320.0 mg/L. While those of the downstream were temperature 29-300C, brightness of 33-34.5 cm, pH 7, DO 4.12-4.57 mg/L, CO2 5.62-
5.99 mg/L, BOD5 2.26-4.12 mg/L, hardness 180.0-240.0 mg/L. The prawn’s morphological characteristics from both areas were different (Asymp values. Sig <
0.05). The prawn from the downstream was smaller than that of the upstream (37.3 mm CL and 52.0 mm CL respectively). The prawn from the upstream shows several characteristics that are relatively longer than those of the prawn from the downstream, namely rostrum length (167% and 137%), total length (84% and 72%), standard length
(140% and 112%), carpus length (21% and 18%), and merus length (50% and 30%) of CL respectively.
Keywords : carapace length, morphological characteristics, Kruskal Wallis test, Mann Whitney tests, shrimp size.
