Peces de la subcuenca del río Catatumbo, cuenca del Lago de Maracaibo, Colombia y Venezuela

Abstract

Registros de literatura, complementados con la revisión de ejemplares de colección de referencia de peces del Instituto Humboldt - IAvH-P (Colombia), Estación Biológica de Rancho Grande - EBRG y Museo de Ciencias Naturales de Guanare - MCNG (Venezuela), muestran que 109 especies nativas de agua dulce y 14 de origen marino y estuarino habitan la subcuenca el río Catatumbo, constituyéndose en el sistema con mayor diversidad de especies de peces de la cuenca del Lago de Maracaibo. Estas especies pertenecen a 10 órdenes, 39 familias y 91 géneros. Los órdenes con mayor número de familias, géneros y especies fueron Siluriformes con 12 familias, 42 géneros y 60 especies, y Characiformes 11 familias, 24 géneros y 32 especies. Las familias con mayor riqueza fueron Loricariidae (16 géneros y 25 especies), Characidae (13 géneros y 18 especies) y Pimelodidae (6 géneros y 8 especies); presentando las restantes 37 familias entre una y cinco especies. De las 123 especies registradas, 69 fueron capturadas y catalogadas como resultados de los muestreos durante el presente estudio y 11 corresponden a nuevos registros para Colombia. Para el río Catatumbo se registraron 61 especies de las 68 consideradas endémicas para la cuenca del Lago de Maracaibo y se establecieron como especies pesqueras 40, de las cuales seis fueron marino-estuarinas y 34 dulceacuícolas. Se discute las variaciones del número de especies registradas en los diferentes listados y sus implicaciones en la riqueza de especies para la subcuenca del Catatumbo.
