520 |a In their recent Opinion, Pauly and Cheung () provide new projections of future maximum fish weight (W∞ ). Based on criticism by Lefevre et al. (2017) they changed the scaling exponent for anabolism, dG . Here we find that changing both dG and the scaling exponent for catabolism, b, leads to the projection that fish may even become 98% smaller with a 1°C increase in temperature. This unrealistic outcome indicates that the current W∞ is unlikely to be explained by the Gill-Oxygen Limitation Theory (GOLT) and, therefore, GOLT cannot be used as a mechanistic basis for model projections about fish size in a warmer world
