'Noble (1886) noted that attacks of Teredo navalis were 'exceptionally virulent' on the Port Elizabeth breakwater (southeast coast). Waldron (1904a,b) noted that at the turn of the previous century, it was most prolific and destructive on the warmer parts of the South African coast, such as in Mossel Bay (southeast coast) in the Indian Ocean. Douglas (1981) reported on control measures for Teredo navalis on a jetty at Knysna, based on a 10- year study.' (Mead et al. 2011b). | ||
