Abstract
Climate variability can affect fish populations and fisheries in numerous ways, including inducing measurable fluctua-tions in fish recruitment, growth, condition, and fisheries production. Fisheries production in the Eastern Pacific (EP) is strongly affected by climate forcing (Beamish 1993). For example, El Niño Southern Oscillation (ENSO) events are associated with significant increases in Sea Surface Temperature (SST), increased precipitation, and decreases in primary productivity in marine environments (Fiedler 2002). Known biological effects of the warm phase of ENSO, El Niño, have included decreases in growth rate in some fishes in the EP (Woodbury 1999). However, warm SSTs during El Niño years have been linked to an increase in growth rate or condition (i.e., weight-length relationships) in some salmonid, lutjanid, and epinephelid fishes (Mcfarlane et al 2005, Williams et al. 2007, Aburto-Oropeza et al. 2010).
