| Cordylophora caspia caused fouling which decreased the efficiency of the cooling system of the Funil Hydroelectric Plant, Paraiba River, Rio de Janeiro, Brazil (Grohmann 2008). After the infestation started, cleaning of the system was required every four months instead of every six years, and costs were substantially increased (Grohmann 2008). | ||
