Another important study would be to utilize tracers, stable isotopes to determine the
assimilation of a typical tilapia feed (tilapia pellets), into the tissues of the fish and
shrimp. Stable isotope ratios from food sources are incorporated into animal tissues
(Pinnegar and Polunin, 1999). Stable isotope ratios and their partitioned fractions could
be followed and evaluated to determine the fate of compounds cycled between the feed,
fish, shrimp, fecal matter and biofilms
