In the present experiment, a pellet stability test (static, room, 60min)
did not reveal significant differences (95.4% to 97.0%; P N 0.05) among
the diets. After 56 days of feeding, shrimp fed the diets containing wakameat
5% had lower (P b 0.05) finalmeanweight,WGand SGR than those
of shrimp fed the control diet (0% wakame diet). The highest values of
final mean weight, WG and SGR were found in shrimp fed diet supplemented
with wakame at 2% inclusion level. Second-degree polynomial
regression of WG and protein retention indicated that the optimum
supplement of dietary wakame should be between 2.17% and 2.87%.
Penñaflorida and Golez (1996) observed a better weight gain in small
Penaeus monodon (0.2 g) fed diet including 5% Kappaphycus alvarezii
meal and a lower growth with the supplementation of 3% Gracilaria heteroclada meal
