The water quality parameters among treatments were similar (Table 2, Fig. 1) and although analysis of variance indicated sig- nificant difference between groups in some parameters, the water quality remained appropriate for the hatchery observed stage of L. vannamei. These parameters were similar that found in a com- parative test between the conventional hatchery system with high rates of daily exchange and the BFT hatchery systems with sources of organic carbon (Lorenzo et al., 2015).
