Abstract

Gut evacuation and its dependence on the temperature in bream Abramis brama, silver bream Blicca bjoerkna, roach Rutilus rutilus, gibel Carassius aurtaus gibelio and carp Cyprinus carpio, held in mesh cages in Lake Balaton, was best fitted by an exponential model in 18 of 36 trials, while in 14 and four trials, a linear and a square-root model, respectively, gave a better fit. Adjusted r2 values, however, often did not differ markedly between the three models. The shape parameter, B, was 0.36 for carp and ranged from 0.81 to 1.24 for the other four cyprinids, according to the general evacuation model expanded with the temperature variable, and fitted to whole data sets. Relationships between the food evacuation rates obtained from the exponential models and the temperature were described by exponential functions for bream, silver bream, roach and gibel.
