Expression profiles of genes associated with chitin hydrolysis: (A) chia.2, (B) chia.3, and (C) chia.5. Relative mRNA levels were evaluated in zebrafish larvae (30 dph), juveniles (60 dph), and adults (90 dph) fed with V instar and prepupae diets compared to controls fed with a diet containing fishmeal as the main protein source. Data are expressed as mean ± S.D. (n = 6). Different letters indicate significant differences in transcript levels among experimental groups within the same sampling time (p < 0.05).
