(A) npc2m/m larvae are mostly identical to npc2+/+ at 6?dpf; however, a few npc2m/m larvae lacked inflated swim bladders or had dorsally curved body axis. A total of 105 npc2+/+ and 112 npc2m/m from five crosses were examined. Numbers of larvae showing representing phenotypes are indicated in each image. Scale bar: 1?mm. (B) Live images of 10?wpf npc2m/m adults showed relatively normal morphology but smaller body size compared with npc2+/+ individuals. Occasionally, npc2m/m adults exhibited scoliosis. Scale bar: 5?mm. (C) Total length of npc2+/+ (31.16±3.01?mm), npc2+/m (31.34±2.68?mm) and npc2m/m (26.62±4.76?mm) adults at 10?wpf. A total of 16 npc2+/+, 32 npc2+/m and 26 npc2m/m adults were examined from two independent crosses. ***P<0.001 (one-way ANOVA and Tukey's test). Total length is presented as mean±s.d. NS, not significant.
