Collected Evidence: Collected Evidence: Integrated aquaculture systems One replicated, controlled study in the USA reported greater growth of scallops grown next to fish farms. A study in Canada found that blue mussels absorbed waste from a salmon farm. A replicated, controlled study in Scotland reported enhanced algal growth when placed adjacent to fish farms. One study in Spain found no evidence that oyster and mussels were feeding on fish farm waste.  Collected Evidencehttps%3A%2F%2Fconservationevidencejournal.com%2Factions%2F932https%3A%2F%2Fconservationevidencejournal.com%2Factions%2F932Fri, 25 Oct 2013 13:57:09 +0100Collected Evidence: Collected Evidence: Construct artificial reefs One controlled study in the Red Sea found no difference in sediment carbon at artificial reef sites adjacent to or away from fish farms. Another publication from the same controlled study reports that the artificial reefs at both sites were colonised with various species with the potential to remove organic compounds from fish farm effluents.  Collected Evidencehttps%3A%2F%2Fconservationevidencejournal.com%2Factions%2F934https%3A%2F%2Fconservationevidencejournal.com%2Factions%2F934Fri, 25 Oct 2013 14:01:17 +0100Collected Evidence: Collected Evidence: Dry sludge in beds Two replicated trials in Canada found sludge drying beds removed phosphorus from freshwater fish farm sludge.
