Table 4 Daily growth rate and proximate biochemical composition of Gracilaria gracilis cultivated in Bizerte Lagoon and Bizerte Bay. Values are means ± SD of results obtained at different depth (from 0.25 m to 3.75 m); n = 45. Means in same row followed by same superscript letter are not significantly different according to the Duncn’s test (P > 0.05).
