Abstract

Biological incrustations, also known as  biofouling , are one of the major problems found in exploitation activities  in the sea and, particularly, in marine fish farming. In spite of the brushing technique being very efficient in the control  of this problem, its adoption may bring about risks of escapes, stress and decrease in the weight-gain by reared fishes in  addition to increases in operational costs, affecting the profitability fish farming. In this paper the brushing technique was  appraised as an alternative for controlling the incidence of biological incrustations on floating net-cages but the results  from the experiment proved it not to be efficient for this purpose.  Key words :
