Water Quality as Sturgeons’ Welfare Indicators in a Farm from the Center of the Country
Abstract
Sturgeons can both make upriver migrations for spawning and downriver for developing and wintering. The importance is related to their meat, roe and the use for Danube Delta repopulation. From a sturgeon farm are harvested water samples from three checkpoints. From the samples there were analyzed physical chemical parameters and microbiological ones. The physical chemical parameters are determined by using Spectroquant Nova 60 photocolorimeter and the micriobiological parameters by cultivation on dehydrated (dry) media. The results interpretation was done according to reference values from literatures for sturgeons and to provisions of the 161/2006 Order of the Environment and Water Resources Management Ministry. Following the researches can be concluded that the fish welfare in the assessed farm are medium, because of the water high micriobial load and of the exceeding of the nitrates and sulfates among the chemical parameters.
