Shrimp farming stands out for the growing demand of the activity, in addition to the high market value of crustaceans. Due to its commercial attractiveness, shrimp farming has become an alternative for production in view of the exploitation of natural resources. In Brazil, shrimp farming intensified in the 1990s with the species Litopenaeus vannamei. Actions taken due to the reduction of effluents rich in nutrients and environmental concerns, provided the implantation of a system with minimal or no water renewal, where natural productivity increases the shrimp diet, resulting in greater crop production. However, in a closed system, rapid eutrophication by nutrients and excess suspended solids becomes a problem for cultivation.For this purpose, clarification becomes an alternative for the control of suspended particulate organic matter, which may reflect in the improvement of the water quality parameters of super-intensive cultivation of Litopenaeus vannamei in a biofloc system.
