G. resistance to water currents). Growth patterns in the field are largely influenced by temperature and food availability. There is a significant relationship between growth rate and temperature (LeCren 1958, Elliott 1976, Houde 1990, Jobling 1983, Mooij & vanTongeren 1990, Wieser et al. 1988a) and also a positive relationship between food consumption and fish growth (Brett & Groves 1979, Condrey 1982, Elliott 1979, Paloheimo & Dickie 1966). 34 The present study was conducted to evaluate the relationship between food availability and growth throughout the critical period after the onset of exogenous feeding.
