Regional Impacts

Economic ImpactShipping/Boating
In Swansea, Wales and Southampton Water, England, heated discharge from power plants prolonged the breeding period of Limnoria quadripunctata and tripunctata , increasing damage to wooden docks (Raymont 1976; Coughlan 1977). In Southampton Water, boring by the two Limnoria species removed 6-13% of untreated wooded test blocks per year (Coughlan 1977).
