The natural carrying capacity of pond bottom seems to be a limiting factor toward
further intensification of aquaculture systems. This point was clearly demonstrated in fish
culture and seems to be true for shrimp pond intensification. Moreover, there is evidence
that the deterioration of the pond bottom, the increase in the amount of waste accumulation
and the development of anaerobic conditions hinder shrimp utilization of feed, retard
growth, possibly create stress and lead to the increase in the concentrations of toxic
metabolites in the pond.
