摘要：

A full scale Atlantic salmon pen rearing experiment with light-reducing black polyethylene netting covers was carried out over one year in order to elucidate effects of reduced illumination on growth, mortality, ectoparasite infestation and net pen fouling. Illumination was reduced by 76% and 44%, respectively, for the two cover types used. Growth was marginally reduced by covers in winter and spring, but was slightly enhanced by the covers in summer and early autumn. Infestation of salmon lice was slightly reduced by the covers. Algal fouling was reduced by the covers, but hydroid settling was higher in covered than in uncovered pens.
