In this case, the haematocrit and erythrocyte values support this hypothesis for the water salinity levels of 14 and 21 g [L.sup.-1].
Up to 7 g [L.sup.-1] were not observed negative effects on growth, survival and haematological parameters by Tukey's test, although by Regression analysis were observed the best results for daily weigh gain, feed conversion rate and survival, respectively, with 5.62, 2.08 and 4.20 g [L.sup.-1] of water salinity; and worsening trend in the haematological parameters from 0.92 g [L.sup.-1] (erythrocyte count) and 2.39 g [L.sup.-1] (haematocrit).
