Research on invasive species and bio-encrustation started at Lactec in 2003, especially aimed at the electricity sector. Our research group currently has been developing projects for various sectors, aimed at preventing the introduction and mitigating impacts of invasive aquatic species, focusing on the golden mussel. The work involves the detection and diagnosis of bioinvasion in water bodies, using the latest technology; monitoring and control of fouling in industrial systems caused by invasive aquatic species (mainly the golden mussel and the invading hydrozoan Cordylophora caspia) and, also, of the ferruginous mud; development of new technologies for better coexistence with bioinvasions and bio-encrustation and cost reduction for projects and the environment. The results have collaborated with solving problems and minimizing impacts, in addition to adding knowledge to the academic and scientific environment. The projects also have an environmental education bias with the population surrounding the projects.


Area of action:

  • Identification of the presence of invasive aquatic species in water bodies using different techniques, including molecular and environmental DNA detection;
  • Diagnosis of occurrence, distribution and stage of the invasion process of aquatic organisms;
  • Monitoring of water bodies for early detection of invasive species and monitoring the invasion process for taking actions;
  • Development of systems for monitoring invasive species and bio-encrustation;
  • Diagnosis of environmental damage, ecological risk and impacts on industrial systems resulting from bio-encrustation;
  • Evaluation of the efficiency of the application of bio-encrustation control methods and their impacts on the environment, non-target species, as well as on the industrial systems and components themselves;
  • Laboratory tests and experiments to check the tolerance of aquatic organisms to control treatments;
  • Elaboration of action plans and management of invasive aquatic species, aiming at preventing the introduction of new species, reducing and mitigating environmental impacts;
  • Research and development of new materials and methods for the control and mitigation of bio-encrustation damages in industrial systems, which make living with the problem less costly in economic and environmental terms;
  • Research and development of methodologies, using the latest technology, for the monitoring of invading aquatic organisms, aiming to make the process more effective, accurate, fast and at a lower cost;
  • Research and development of methodologies for monitoring aquatic organisms and bio-encrustation in real time, with the objective of increasing the efficiency of prevention and control actions, increasing operational safety and reducing costs.



► Our research group maintains partnerships with other institutions and researchers, which allows the involvement of professionals with relevant experience in different areas of knowledge and adds value, both in terms of human resources and infrastructure. Examples of these partnerships are the Laboratory of Biological Interactions at UFPR and the Senai Institute of Innovation in Electrochemistry.

Services performed:

  • Environmental monitoring services and efficiency of golden mussel control systems in hydroelectric plants
  • Consultancy to define measures to avoid operational problems arising from the bio-encrustation of the golden-mussel (Limnoperna fortunei) in hydroelectric plant modernization projects
  • Monitoring of golden mussel in water bodies
  • Detection of invasive species through DNA and environmental DNA
  • Laboratory evaluation of the toxicity of chemicals to the golden mussel (Limnoperna fortunei) and its compatibility with different materials
  • Distribution of the golden mussel (Limnoperna fortunei) in the state of Paraná: detection through environmental DNA in ETAs and reservoirs
