In the present study, we aimed to evaluate the effects of intraperitoneal tagging with dummy transmitters on growth of juvenile European catfish (Silurus glanis L.) within a period of 75 days kept in indoor condition. The initial mass of juveniles (mean +/- SD) was 236.5 +/- 21.2 g. We compared growth by analysing specific growth rate (SGR) and the slopes of the growth curves between control individuals and those of experimentally tagged (n = 6 per group). Body mass was increased in both control and experimentally tagged fish. There was no significant difference in SGR between tagged and untagged fish; 0.26 +/- 0.11 %/day vs. 0.38 +/- 0.12 %/day respectively. These results suggest that the telemetry studies of juvenile European catfish to be relevant and unbiased.
