Does raising the water temperature lead to faster growth rate?

Most people might think that

raising the water temperature –> more appetite & eat more –> faster growth.

This is true to a certain extent, but the upper limit of the temperature would vary between different fish species (a fish is not just a fish).

	Abstract:	The effect of three different temperatures on growth in a first progeny generation, hatchery reared, subarctic population of European whitefish (Coregonus lavaretusL.) were investigated. The whitefish (start weight 444 g, ±SD125 g) were reared for 60 days at three constant temperatures; 15, 18 and 21°C and under ambient light regimes for 70°N latitude. The results showed that temperature had a significant influence on the growth of the fish with the highest increase in weight increment occurring at 18°C (mean final weight 656 g ± SD151 g) compared with the growth of fish held at 15°C (mean final weight 591 g ± SD143 g) and 21°C (mean final weight 505 g ± SD121 g). The cumulative per cent mortality of the fish during the experimental period increased with increasing temperature, from 10% at 15°C to 30% at 21°C. The present study indicates that the optimal temperature for farming of European whitefish is somewhere between 15 and 18°C rather than between 18 and 21°C.
