Ikeda (1985), from experimental data of growth, reported a fast growth up to the adult stage (35 mm body length), which then slow down towards full size (60 mm body length). The growth rate obtained using the equation RNA-growth rate of Båmstedt & Skjoldad (1980) resulted 0.17 -0.19 mm day-1 for specimens greater than 30 mm body length (Ikeda, 1989).
