The influence of oceanic circulation and bathymetry on the fish larvae retention inside Mejillones Bay, northern Chile, was examined.
Fish larvae were collected during two coastal upwelling events in November 1999 and January 2000.
An elevated fish larvae accumulation was found near an oceanic front and a zone of low-speed currents.
Three groups of fish larvae were identified: the coastal species (Engraulis ringens and Sardinops sagax), associated with high chlorophyll-a levels; larvae from the families Phosichthyidae (Vinciguerria lucetia) and Myctophidae (Diogenichthys laternatus and Triphoturus oculeus), associa...
