Karpowership Members of some small fishing communities along SA coast say they are fearful of the impact of floating powerships on fish stocks. Last week the environmental assessors for Karpowership SA found that a project to moor five floating power stations at three SA harbours should be given the go-ahead. The impact reports, which are now being studied by the Department of Forestry, Fisheries and the Environment, argued that the impact on marine ecology would likely be 'low'. Representatives of some small-scale fishing communities say they are worried about the impact that floating powerships will have on scarce fish stocks along SA's coast.
