Fig. 4. Fish survival and behavioral classification of goldfish after whole spinal cord crush. (A) Behavioral status of goldfish 190 days after spinal cord crush. Of the 25 surviving fish, 12 regained equilibrium and C-starts (48%), two regained equilibrium but not C-starts (8%), six did not gain equilibrium and had no apparent body abnormalities (24%; a C-start could be elicited in one of these fish), while five had body abnormalities (20%) that are believed to have hindered behavioral recovery. (B) Distribution of the number of experimental fish that died over the 190-day postoperative interval. Twenty of the 45 experimental fish died during the course of this study. The distribution of the number of fish that died reveals two clusters: one at 3-52 days and another at 91-162 dayspostoperatively.
