Figure 2. Behavioral differences among zebrafish lines in the SI preference test.
AB line zebrafish spent a significantly greater proportion of time in the chamber with the stranger fish (**p < 0.05), while Petco short-fin zebrafish spent more time with the empty blue box (*p < 0.01). N = 12 fish, except N = 9 for golden. The differences observed among lines were not due to differences in the number of chamber entries the fish made, which averaged 29 ± 7 for all lines.
