Fig. 5
Total proportional increment of N. granulata juveniles from the three studied populations cultured in laboratory and fed with five experimental diets. References as in Fig. 2. Numbers on bars indicate the a posteriori paired comparisons among diets (Holm–Sidak test); same number signifies no differences between pairs (p > 0.05). Horizontal bars indicate results of a posteriori paired comparisons (Holm–Sidak test) among populations; bars join no different groups (p > 0.05)
