Abstract
This study assessed growth of individually tagged brown trout Salmo trutta in a temperate system of north-west Spain (2010-2012). This study identified notable individual variation in fish growth with individuals growing sub-optimally compared with laboratory-based growth-model predictions in most cases (85.5% of individuals). The present observations of suboptimal growth need to be considered in view of intraspecific competition or limiting food resources instead of thermal regimes.
