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

https://doi.org/10.5878/59q2-7h64

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.
