. For African countries,
for example, a simulation model for the production of Nile tilapia in
mixed, all-male and in polyculture with a predator (African catfish,
Clarias gariepinus or African snakehead, Parachanna obscura) has been
developed (de Graaf et al., 2005) and run with data from Tanzania
(Kaliba et al., 2006) and Kenya (Kaliba et al., 2007), in order to determine
sustainable methods under local conditions.
