520	|a"Following observations of growth abnormalities in oysters, Crassostrea gigas, from Nanoose Bay, samples of sediments, water and oyster tissue were analysed for organotins. Highest concentrations of tributyltin (TBT) in both sediments and water were measured at a salmon farm, and highest concentrations of TBT in oysters were measured at an oyster farm adjacent to the salmon farm. In March, 1987, Environment Canada and Agriculture Canada advised the aquaculture industry that TBT is not permitted for use as a marine growth retardant on net pens and the products are no longer available in retail outlets"--Abstract.
