Monitoring water quality in fish farms

Digitalizing fish farming in the Petite Camargue Alsacienne

Atlantic salmon populations have declined sharply due to degraded water quality and dam construction. The nternational Commission for the Protection of the Rhine (ICPR) has set itself the goal of reintroducing the species. For optimal breeding, an Endress+Hauser solution is used to monitor water quality and thus create the best growth environment for the fish.

Digital monitoring of fish farming tanks

Fish farming tanks to ensure best breeding conditions for salmons

Results

  • Reliable monitoring solution to ensure optimal growth of the salmon population

  • Digitalized access to all measurement data on the site as an add-on

  • The measured values and sensor condition are transmitted wirelessly via digital gateways, and can be accessed remotely using Netilion

Fish farm manager Olivier Sommen from Petite Camargue Alsacienne

We needed measuring sensors to monitor the recirculated water circuit, and a system for managing measurement data with alarms to indicate threshold breaches or other issues.

Backround

Since the 1950s, the number of Atlantic salmon has decreased significantly due to deteriorating water quality and an increase in the number of dams built. However, the International Commission for the Protection of the Rhine launched a program to reintroduce the migratory species. The Petite Camargue Alsacienne fish farm breeds Atlantic salmon to repopulate the Rhine. The aim of this breeding platform is to guarantee optimal spawner fertility and minimize losses from uncontrolled breeding.

Our solution

To meet the requirements for monitoring the quality of recirculated water in the enclosures a measuring station was installed. Each water quality parameter is analyzed: oxygen level, pH, temperature, nitrate content, as well as the physical parameters of the recirculation circuit, for example the water flow rate in the pipe and the water pressure and level in the recovery tank. This measurement data is then sent to a local management system which allows it to be viewed on site and mobile.
