The mean percent survival of the prawns fed
diets without MT was significantly higher (P 5
0.048) than that of all prawns fed diets containing
a combination of all levels of MT (Table 1).
Mean survival between male and female prawns
(P 5 0.43) did not differ significantly among
durations of feeding MT-containing diets (P 5
0.229), the concentrations of dietary MT (P 5
0.2), and the combination of duration and concentration
of dietary MT (P 5 0.104).
