Both feeding and metabolism will slow at both ends of the species temp range. Most fish are cold blooded which causes the above. Bob was talking about max growth at near optimum temps = growing days. Growth rates do vary even within the growth days. Digestion rate is highly variable based on metabolism which is controlled by temps. Feeding is similar but not identical to growth (offset a little on the temp scale).
