| Internal electronic tagging is a major issue in flatfish species due to the small size of abdominal cavity. In this study, three tag types, referred to as Nonatec, nano and mini, were evaluated in three weight classes of Senegalese sole: small (0.3 g), middle (0.8 g) and large (2.0 g). Tags were injected from the blind side and fish were carefully handled to minimize sharp movements. Tag losses were 8% in the small size class, between 5.2 and 15.1% in the middle size class and 2–4% in the large size class. The mortality rates ranged between 2.0 and 15.0% with the lowest values in the large size class. No negative effects of tags on growth (tagged vs non-tagged fish using a middle size class) were found after 57 days of culture. Four additional trials using... |
