Once loss of nociception and voluntary swimming movements were verified, a second sampling of 200 µL of blood was drawn sublingually. Once the blood samples from the two sampling periods were collected, they were transferred to microtainer tubes and centrifuged at 25 000 rpm for 5 min. Plasma was collected and kept frozen at -20 °C until the day of analysis For more details for blood sampling in fish: 1.-Lawrence, Michael J., Graham D. Raby, Amy K. Teffer, Ken M.

Description of data process To meet the assumption of normality, a logarithmic transformation of the induction and recovery times was suggested by the Box-Cox statistical program . The Box-Cox equation is as follow (y_ij^(?-1))/?=?+?i+?ij.; where yij is the variable response; ?? is the statistical general mean; ???? is the effect of the treatment and ?ij is the random effect of the mean. For descriptive statistics the means and standard deviations of the original data were used. |
