Description
Abstract
This paper reviews the patterns observed in the diversity and structure of the
macrofauna benthic community under the influence of fish farming. First, we explain the
effects of organic enrichment on the sediment and the consequences for the inhabiting
communities. We describe the diversity trends in spatial and temporal gradients affected by
fish farming and compare them with those described by the Pearson and Rosenberg model.
We found that in general terms, the trends of diversity and other community parameters
followed the Pearson and Rosenberg model but they can vary to some extent due to
sediment local characteristics or to secondary disturbances. We also show the different
mechanisms by which wild fish can affect macrofauna diversity patterns under fish
farming influence. In addition, we comment the importance of the macrofauna diversity in
the ecosystem functions and propose some guidelines to measure functional diversity
related to relevant processes at ecosystem level. We propose more research efforts in the
main topics commented in this review to improve management strategies to guarantee a
good status of the diversity and ecosystem functioning of sediments influenced by
fish farming.
