Environmental monitoring of two fish waste ocean disposal sites in Newfoundland and Labrador, Canada
Sediment contaminant and benthic community surveys were conducted at two fish waste ocean disposal sites in Newfoundland and Labrador, Canada, to assess the environmental impacts of the disposal activities. Despite a dispersive ocean environment, fish wastes accumulated at both sites, initially disturbing the benthic community through organic enrichment and oxygen depletion, but causing no elevation of sediment contaminants. After three years without disposal, the benthic community at one of the sites shows signs of recovery from the disturbance.
