To determine the apparent digestibility of the ingredients, 60 juveniles (9.0 ± 1.3 g)
were acclimated in a fiberglass 1000-L tank for 1 week and fed with the control diet at
10 % of their body weight adjusted daily, three times a day (at 08:00, 11:00 and 17:00 h).
After acclimation, they were randomly distributed in six 60 L aquariums, in RAS at a
stocking density of 5 shrimp per aquarium-1
, until a 1.5 g sample of feces was obtained.
Takeuchi (1988) calculated the determination of digestibility of the ingredient (seaweed
meal) as follows:
