Resumen
Para cumplir con el objetivo del trabajo de investigación “Determinar las especies de peces de agua dulce autóctonas factibles de desarrollo en ambiente controlado”, se realizaron visitas periódicas a diferentes lugares cercanos a ríos de la Provincia del Guayas para cumplir con un programa de muestreo en busca de los estadios larvarios y juveniles de peces que permitieran ser sembrados en estanques, previa identificación, para ver la posibilidad de su desarrollo en cautiverio. Se estudiaron varias especies que dieron resultados positivos en su crecimiento destacándose la especie Lebiasina bimaculata.
En esta investigación se pudo encontrar que Lebiasina bimaculata (huaija), Hoplias microlepis (Guanchiche), Rhamdia cinerascens (barbudo) y Aequidens rivulatus (vieja azul) son especies que se desarrollan en un ambiente casi natural, sin alimentación; además, son especies consumidas por las personas especialmente de las zonas aledañas a los ríos, lagunas, esteros y pozas donde se encuentran.
Este trabajo abre las puertas para nuevas investigaciones que tengan relación con la biología de la especie, sus hábitos alimenticios y la reproducción de los mismos.
To fulfill the objective of the investigation work “To determine the feasible autochthonous species of fish of fresh water of development in controlled atmosphere”, they were carried out periodic visits to different near places to rivers of the County of the Guayas to fulfill a sampling program in search of the biology cycle of fish that allowed to be sowed in ponds, previous identification, to see the possibility of their development in captivity. Several species were studied that gave positive results in their growth standing out the species Lebiasina bimaculata. In this investigation it could be that Lebiasina bimaculata (huaija), Hoplias microlepis (Guanchiche), Rhamdia cinerascens (barbudo) and Aequidens rivulatus (vieja azul) they plow species that it plows developed in an almost natural atmosphere, without feeding; also, they plows species consumed especially by people from the nearer areas to the rivers, lagoons, tidelands and puddles where they it plows. This work opens the doors for new investigations that have relationship with the biology of the species, its nutritious habits and the reproduction of the same ones.
