Sustainability of freshwater salmonid farming in a karst river ecosystem

Eutrophication in freshwater ecosystems is one of the major environmental problems. Aquaculture industry is greatly impacting aquatic environments by introducing nutrients and microorganisms through nutrient enrichment of water column and sediment. The aim of this research was to evaluate the impact of a salmonid farm on the environment. Water and sediment were sampled once a season from spring 2016 to spring 2018 at the commercial salmonid farm in Šibenik-Knin County. Samples were processed for bacterial indicators (total coliforms, Escherichia coli, enterococci and Pseudomonas aeruginosa, total number of bacteria). Physicochemical parameters of water on the salmonid farm and the surrounding environment were analysed, as well as granulometric and mineral composition, carbonates and organic matter in the sediment. The objective was to determine water quality above the fish farm, in the fish farm and below the discharge of water in the river, and sediment characteristics in the fish farm and downstream of the fish farm. Water and sediment quality indicators were statistically analysed by Principal component analysis (PCA) in order to determine any grouping regarding locations and seasons. Results for the water do not differentiate fish farm location from the other sampling points, while sediment results show a mild trend of separating fish farm regarding total coliforms and total number of bacteria. Sedimentology analysis detected somewhat higher organic matter content in the farm sediment (4.05-4.18%), indicating its increased intake compared to the river (1-1.5%). This indicates that the impact of salmonid aquaculture is limited in the farm boundaries.
