Notes
The influence of temperature and food quality was studied on the following energy balance parameters of B. angularis: ingestion, production, growth and mortality. The ingestion rate rises to an optimum at 15 and 20 degrees C and decreases at 25 degrees C. The other rates increase continuously over the 5-25 degrees C range. The Q10-values of production rate are higher than those of ingestion rate. Temperature also modifies the relationship between food concentration and bioenergetic rates. They react according to a Monod function (production at all temperatures, growth at 10 degrees C) or decrease at high concentrations (growth at 15 and 20 degrees C).
