Preliminary data of biofouling impact in cage farming of seabass Dicentrarchus labrax (Linnaeus, 1758)

Since the beginning of mariculture activity, biofouling has negatively affected the biological and physiological state of cultivated organisms. Biofouling succession on aquaculture cages decreases the size of the mesh openings, as well as slows down the exchange of the water mass through the net. Consequently, the concentration of oxygen in the cages is reduced. Furthermore, unwanted weight of the net caused by biofouling negatively affects profitability, and therefore the economy of cultivation. This research was carried out in situ with the help of an autonomous diving apparatus, using photographs and the square method. The dynamics of the occurrence of biofouling and its influence on the mesh openings of the nets on the cages for seabass farming Dicentrarchus labrax (Linnaeus, 1758) were monitored in relation to the control net. For sampling purposes, a square construction with a fixed extension was designed. Using ANOVA, a statistically significant difference was identified between the sides of the cages and the side of the control net (p<0.001).
