Abstract
It was obtained the optimal rotation time for the polyculture of tilapia
nilótica and white shrimp in freshwater, with a bioeconómic model. Data
for modelling were extracted from an experiment conducted in
CINVESTAV-IPN, unit Mérida, during the summer of 2008. The stocking
densities studied were 32.2 tilapia/m3 and 33.7 and 50 shrimp/m2. For
simulation were considered the technical and economic characteristics of
tilapia culture in Yucatán Mexico. Randomness was included in the two
most influential variables of the system, in order to obtain more attached to
reality results. The optimal rotation time strategy was longer than the
commonly used by the tilapia farmers
