. There is increasing concern over the environmental impact of freshwater cage culture, but there is a lack of information on the amounts and nature of the wastes produced. This study presents measurements of the total solid waste arid solid carbon, nitrogen and phosphorus loadings from five Scottish rainbow trout, Salmo gairdneri Richardson, cage farms, and shows a significant input of solids below the cages. The results indicate a considerable variability in solid output which was partly due to variations in the feeding rate of fish with the cages, but was also thought to be due to variations in management on individual farms. The results compare well with other studies on land‐based pond and tank systems and provide useful estimates of solid waste loadings for the prediction of environmental impact.
