Abstract:
Available information about bioencapsulation in Artemia
indicates that there is no agreement about the food concentrations to
fulfill this objective. In this study, experiments with 15 different
concentrations of 5 µm diameter latex particles were made. The behavior of
different size classes of animals analyzed is shown with results stating
that their feeding behavior is a function of size. An increase in the
percentage of filled digestive tracts of individuals occurs when the
concentration of particles in the medium increases. Concentrations higher
than 12 500 particles/ml allow filling of the digestive tract in
individuals of up to 3.2 mm size in 1 h of treatment. Concentrations of 200 000
and 400 000 particles/ml allow the total filling of the digestive tract
of individuals of up to 5.6 mm long in 1 h. For individuals larger than 5.6
mm, the highest concentrations of particle are those that allow the filling
of the digestive tract most efficiently.
