Data from various stunning attempts for Nile tilapia (Oreochromis Niloticus)

The study that this data supports aimed to evaluate the stunning effectiveness of various stunning attempts on Nile tilapia by measuring brain activity to assess neurological indicators of conscioussness/unconsciousness. Thus, this data set contains raw data from measurements of brain activity using electroencephalography in Nile tilapia. Data were collected before and after stunning attempts using the following stunning methods: Live chilling, mechanical stunning (percussion), electrical stunning and a combinational approach consisting of electrical stunning followed by direct throat cutting and chilling. The data is extracted from Labchart, where data was collected using a Powerlab and a Bioamp. The data contains the mean amplitude during 20-80 s during the 200 ms long light and dark phases. The data set also contains the mean amplitude during 10 s before short electrical exposure as well as the mean amplitude of the signal during the time that the epileptic-like seizure lasted after electrical exposure (i.e., 9-27 s). The data also include information on the time that visually evoked responses (VERs) were lost after stunning, as well as the induction time (when applicable) for the loss of VERs.
