Abstract

This work highlights its importance as a source of food and its impact on the local economy, essential to guarantee its sustainability and the health of aquatic ecosystems in the region.  The objective was to evaluate the morphometric characterization and proximal composition of the muscle tissue of the native fish Hoplias microlepis (guanchinche) in the basin of the Vinces, Quevedo, Mocache and Buena Fe rivers, in Los Ríos, Ecuador. A completely randomized design (DCA) was applied with a factorial arrangement of 1 ×4, morphometric, nutritional and performance characteristics were analyzed, significant differences were found in weight and morphometric measurements, with Vinces being the locality with the highest weight (265 g) and standard length (24.97 cm). Regarding the moisture content in muscle tissue, Vinces had the highest percentage (89.39%), while Mocache had the lowest (63.27%). In ashes it was higher in Buena Fe (6.06%), the lowest in Mocache (5.22%). In terms of lipids, Buena Fe showed the highest percentage (2.23%), followed by Mocache (2.03%), Vinces (1.86%) and Quevedo (1.47%). Blood protein concentrations varied between localities, and no statistically significant differences were found (p = 0.1104). As for the yield of eviscerated fish, it was 73.63% for the Vinces locality, in the fillet yield it was 65.36% for the Buena Fe locality. It demonstrates the importance of the locality in fish quality and its economic and ecological impact, the influence of environmental, nutritional and biological factors on the variability of the characteristics of the guanchiche.
