Mutant fish demonstrate delayed hatching and swim bladder development, and motor skill impairment. Bar graphs representing the percent (%) of embryos hatched at 72 hpf (left bars) and 78 hpf (right bars), while n denotes number of clutches (A), and the percent of swim bladders inflated at 5 dpf, while n signifies number of clutches (B). Movement in pixels acquired via the mean square difference (MSD) assay at 8 dpf, while n denotes the number of fish (C). Time in seconds that adult zebrafish could efficiently swim without being swept into the whirlpool as observed in the spinner task assay, n represents the number of fish (D). In all cases, Wt AB are shown in purple bars, and Mgat1b−/− in gold bars. Data are presented as mean ± SEM and were compared using Student’s t-test (*** p < 0.0001; ** p < 0.01; * p < 0.04).
