Colonización Acuática: Expansión de la tilapia en el río Churute
Palabras clave:

En Ecuador, el río Churute, presentaba presencia confirmada de tilapia, aunque sin estudios previos que cuantifiquen su impacto en la fauna íctica local. Por ello, el presente estudio tuvo como objetivo describir la composición de la ictiofauna en el río Churute, analizar la distribución y abundancia de tilapia, y evaluar su impacto sobre las especies nativas. Para ello, se desarrolló un estudio descriptivo en 25 sitios distribuidos a lo largo de un tramo de 17 km del río. La captura de peces se realizó mediante atarrayas. En cada sitio se registraron datos de abundancia, biomasa, longitud total y peso de los ejemplares. La identificación taxonómica se efectuó con claves especializadas, y para el análisis se calcularon índices ecológicos de riqueza, diversidad y el Índice de Importancia Relativa (IRI). En total, se capturaron 1.065 ejemplares de 20 especies de peces, distribuidas en 6 órdenes y 13 familias. De estas especies, 70% eran nativas, 25% endémicas y 5% introducidas. La especie introducida correspondió a Oreochromis spp. (tilapia) y entre las especies endémicas destacaron Leporinus ecuadorensis, Ichthyoelephas humeralis, Saccodon terminalis y Andinoacara blombergi. El IRI mostró que Oreochromis spp. fue la especie dominante (IRI = 4.0075,58), con una abundancia relativa del 61,13%, biomasa del 38,55% y frecuencia de aparición del 17,01%, y reproducción activa confirmada. Especies endémicas como Leporinus ecuadorensis, Ichthyoelephas humeralis y Brycon dentex presentaron distribuciones más limitadas. Este estudio cuantifica la dominancia y expansión de la tilapia en el río Churute, estableciendo su impacto en la composición y diversidad de la ictiofauna nativa. Los resultados constituyen una base para futuros trabajos de manejo y control de especies exóticas en ecosistemas protegidos, y para la conservación de la biodiversidad acuática en áreas vulnerables.
