  1. The column title “Recovery” refers to the condition where the fish were exposed to 130% TDG for 2 h and then allowed 2 days of recovery. Each fish was used only once. Body length was analyzed with one-way ANOVA, and no significant difference in body length was found in the Ucrit and Uburst groups.
