The use of greenhouse-enclosed shrimp biofloc culture rearing system (BFT systems) is a technology that makes it possible to increase the culture period in higher latitudes by reducing water exchange and minimizing heat loss
(McAbee et al. 2003; Arnold et al. 2009; Crab et al. 2009; Li et al. 2009). However, culture intensification is necessary in order for this

approach to succeed. Increased stocking density coupled with reduction of water exchange results in a large accumulation of wastes, primarily nitrogen compounds. In exchange culture systems these wastes can be easily eliminated
(Read and Fernandes 2003; Piedrahita 2003; Cohen et al. 2005). High concentrations of these wastes are toxic to the reared organisms (Ostrensky and Wasielesky 1995; Van Wyk and Scarpa 1999; Lin and Chen 2001; Timmons
et al. 2002). Thus, the economic success of a given culture system depends on the balance achieved between production of wastes and the assimilation capacity (Thakur and Lin 2003;
Crab et al. 2009)
