Resumen


Las Piedras es un pueblo costero de la Península de Paraguaná del Estado Falcón, en el que durante el mes de Octubre de año 2009 se presentó una elevada mortandad de Sardinella aurita en su Bahía, desencadenando una serie de problemas ambientales que despertaron el interés por determinar las causas de la muerte de esta especie en la bahía de Las Piedras. El diseño de la investigación es no experimental, tipo de campo y nivel explicativo. En esta se estudiaron las variables físicoquímicas, ambientales y biológicas de la Bahía de Las Piedras durante los días del fenómeno. Los resultados obtenid-os se analizaron mediante un análisis de varianza de un solo factor con pruebas a posteriori de HDS Tukey y Duncan, de-terminándose que las especies murieron por un efecto sinérgico entre déficit de oxígeno durante la noche, fallas de ali-mentación y estrés térmico, a consecuencia de una posible estratificación de las masas de agua debido alteración en las condiciones ambientales de la zona, causadas por la presencia del fenómeno El Niño.
