Survival in the treatments with seaweed meal (NK4 %, NK8 % and NG4 %) was similar to that in the control diet.
NG8 % had the highest numerical survival, which suggests that the effect of each type of seaweed meal on survival was different due to different active principles.
Each probably has an optimum at different concentrations, and higher concentrations do not necessarily give better results as seen in the NG8 % diet that had less consistent survival.
The results in assessing brown seaweed in three concentrations (10, 15 and 20 %) found the best survival rates at concentrations of 10 %
