Caracterización morfométrica y composición proximal del tejido muscular del pez nativo guanchiche (Hoplias microlepis) en la cuenca del río Vinces, en Ecuador

Abstract

Este trabajo, resalta su importancia como fuente de alimento y su impacto en la economía local, esencial para garantizar su sostenibilidad y la salud de los ecosistemas acuáticos en la región. El objetivo fue evaluar la caracterización morfométrica y composición proximal del tejido muscular del pez nativo Hoplias microlepis (guanchinche) en la cuenca de los ríos Vinces, Quevedo, Mocache y Buena Fe, en Los Ríos, Ecuador. Se aplicó un diseño completamente al azar (DCA) con un arreglo factorial de 1 ×4, se analizó las características morfométricas, nutricionales y de rendimiento, se encontró diferencias significativas en el peso y las medidas morfométricas, siendo Vinces la localidad con el mayor peso (265 g) y longitud estándar (24.97 cm). En cuanto al contenido de humedad en el tejido muscular, Vinces presentó el porcentaje más alto (89.39%), mientras que Mocache tuvo más bajo (63.27%). En cenizas fue mayor en Buena Fe (6.06%) el más bajo en Mocache (5.22%). En términos de lípidos, Buena Fe mostró el porcentaje más alto (2.23%), seguido de Mocache (2.03%), Vinces (1.86%) y Quevedo (1.47%). Las concentraciones de proteínas sanguíneas variaron entre localidades, no se encontraron diferencias estadísticamente significativas (p = 0.1104). En cuanto al rendimiento del pescado eviscerado fue de 73,63% la localidad Vinces, en el rendimiento del filete fue de 65.36% para localidad Buena Fé. Demuestra la importancia de la localidad en calidad del pez y su impacto económico y ecológico, la influencia de factores ambientales, alimenticios y biológicos en la variabilidad de las características del guanchiche.

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.
