“…However, fish larvae abundance was higher in December 2011 (rainy season) and thus, it seems likely that other factors besides food concentration are the main drivers of ichthyoplankton abundance. The larvae of anchovies (Cetengraulis mysticetus), a commercially important species, were more abundant in December 2011, which is consistent with their spawning period documented in the Colombian Pacific (October -December) (Beltrán-León, 2002). Likewise, higher abundances of C. mysticetus larvae have been found during the rainy season in Bahía Cupica (A.…”

“…Se observa actividad reproductiva más intensa durante el fenómeno de El Niño que durante el fenómeno de La Niña; sin embargo, con la actual información no se alcanzan a comprobar dichas diferencias y es necesario hacer estudios más detallados al respecto. Se ha demostrado por lo pronto, que tanto El Niño como La Niña afectaron de manera similar el comportamiento reproductivo de la carduma (Cetengraulis mysticetus) en el Pacífico colombiano, observando varios máximos reproductivos en el año, siendo que en condiciones normales tiene uno solo y es considerada como desovante total (Beltrán-León, 2002).…”

“…y Coryphaena hippurus. Beltrán-León (2002) hace análisis más detallados de los efectos de estos fenómenos en la distribución y abundancia de C. myticetus para la misma zona. En Perú se ha visto cómo las especies demersales tienden a migrar hacia el sur (Espino, 1991); en Ecuador y Perú el camarón también ha sido más abundante de lo normal durante el fenómeno de El Niño (Jiménez & Herdson, 1984;Espino, 1991).…”

“…Esto implica necesariamente el transporte de huevos fuera de la costa, aumentando su densidad en la parte oceánica. De igual manera se nota una posible respuesta de la familia Engraulidae a los cambios medioambientales anómalos (altas temperaturas) que se presentaron (Beltrán-León, 2002).…”

“…This necessarily implies the transport of eggs away from the coast, increasing their density in the oceanic zone. Similarly, it is possible that the Engraulidae family was responding to the anomalous environmental changes (high temperatures) it faced (Beltrán-León, 2002).…”
