Assessment of the environmental sustainability of cobia fish farm (Rachycentron Canadum) in the bay of Ilha Grande - Brazil and the relationship with benthic macrofauna

Studies on the sustainability of aquaculture have been carried out around world. The input organic matter in sediment and influence current velocity deposition particles produced by fish captivity can be used to assess distribution benthic assemblages below marine farms. Sediment organisms were collected April, September December 2019 August October 2020 farming area two control areas Bananal cove Ilha Grande Bay. measurement speed local currents was net-tank, periods 24 days April July 2019. heterogeneity biological data evident between collection points, indicating that several factors macrofauna. There no correlation values species richness for diversity. Marine Biotic Index (AMBI) three stations smaller than 1 (one), is, there a predominance sensitive pollution enrichment. farm considered an unpolluted environment. results also indicated presented insufficient intensities disperse areas.
