The purpose of this study was to determine the morphometric and meristic characteristics, growth of Signal barb fish in the Tasik river. The method used in this research is a survey method. Morphometric characteristics of Signal barb fish Bodyweight (BW) ranges from 4-73 gr, Total Length (TL), Standard Length 6.3-15.5 mm (SL), Head Length (HL) 1.8-2.5, Snout Length (SL) 0.5, Dorsal Fin Height (DFH) 2.3, Dorsal Fin Length (DFL) 3-7, Eye Diameter (EM) 0.8, Tail Trunk Height (TTH) 0.8-1.8, Body Height (BH) 2-4.5, Pectoral Fin Length (PFL) 2 cm and Belly Fin Length (BFL) 2 cm. The meristic characteristics of Signal barb fish are the number of Linnea Literalis (LL) as many as 35-38 scale, 13 Circular Body Scales (CBS), 11-13 Front Fin Dorsal Scales (FFDS), the Scales Around the Tail (SAT) a total of 5, Dorsal Fin (DF) of DI. 23-26 fin radii, Ventral Fin (VF) of 9 fin radii, Pectoral Fin (PF) of 11-14, Anal Fin (AF) a total of 7 fin radii and a Caudal Fin (CF) a total of 20-22 fin radii. The growth pattern of signal barb fish in the Tasik River is negative allometric with the condition factor value an average value of 0.42
