The purpose of the research was to study the morphometric and meristic characteristics of the wild mouse fish (Leporinus ecuadorensis) that lives in the Babahoyo River. 250 specimens with a weight range of 90 to 168 g were purchased from artisanal fishermen, which were then transported to the meat plant of the “La María” Campus of the State Technical University of Quevedo where the morphometric measurements and meristic counts were carried out, the correlation between the morphometric measurements (weight, total length, head, trunk and tail width as well as the perimeter of the head, trunk and tail) descriptive statistics were also applied. For meristic characters, the spiny fin rays were counted: dorsal, pectoral, pelvic, anal and caudal, which were compared by frequency analysis. The results show that the length is directly proportional to the weight of the fish, the correlation coefficients of the morphometric measurements are directly proportional to the weight since they presented values greater than (r2 = 0.50). This species has an elongated morphology, the average weight was 120.15 ± 19.41 g and a total length of 23.38 ± 3.48 cm. These fish had different numbers of rays in their fins, the following predominating: dorsal fin (12 rays); pectoral fin (13 rays); pelvic fin (9 rays); anal fin (11 rays) and caudal fin (23 rays), it is concluded that this species presents isometric growth.
