Development of a biosensor technology for environmental monitoring and disease prevention in aquaculture ensuring food safety


Objective of the project

The objective of the EnviGuard project is to develop a highly specific and precise in situ measurement device for currently hard to measure man-made chemical contaminants and biohazards (per definition viruses, microorganisms and toxins from a biological sources) that can be used as an early warning system in aquaculture and as an environmental monitor to assess the good environmental status of the sea.

Around a group of marine scientists, aquaculture companies, including shellfish and fish farmers as well as an aquaculture technology provider, a consortium of highly specialized SMEs from the different fields mentioned below and experts from some of the most renowned European research institutions have joint forces to develop the EnviGuard system.

The modular EnviGuard system will be made up of three different sensor modules (microalgae / pathogens, i.e. viruses & bacteria / toxins & chemicals), that are connected to the common interface EnviGuard Port which saves, displays and sends the collected data to a server. The internet platform EnviGuard.NET gives the users the possibility to access real-time data from in situ measurements and facilitates remote control of the EnviGuard system that is located in the field.

By the end of the project the EnviGuard will be able to detect and quantify in situ

  • relevant toxic algae in European waters (e.g. Alexandrium minutum, Alexandrium tamarense, Alexandrium ostenfeldii and Pseudonitzschia sp.),
  • pathogens relevant to European aquaculture (specifically Betanodavirus and E .coli)
  • emerging pollutants i.e. toxins (specifically okadaic acid and saxitoxin) and persistent, man-made pollutants in the marine environment (specifically PCB126 and PCB118).

Contribution of Multitel

Multitel mainly contributed to the development of the optical reading system for interrogating the different lab-on-chip sensors developed in the project. In particular MULTITEL developed a multi-channel spectrometer integrated into the interrogation platform.
