The first line of defence

Invasive Aquatic Species Desinfectant

It is the responsibility of all who use our waterways for work or pleasure to prevent the spread of non-invasive species on their clothes, equipment and everything else that comes into contact with water. INVAS Biosecurity is proud to introduce Virkon Aquatic to Ireland. This disinfectant will be a major part of the armoury in our fight against Invasive Aquatic Species that are now infecting and threatening our ecosystems.

Inland Fisheries Ireland is engaged in an ongoing campaign to educate anglers, boat users, public authorities and other stakeholders of their responsibilities in preventing the spread of damaging invasives species. They are encouraging all water users to take the necessary steps to ensure that their boats and equipment are clean and decontaminated before entering any watercourse.

It is important that all water users follow the best practice of disinfecting their gear before entering water.

Disinfection Kits

With legislation obliging organisations and individuals to prevent the spread of invasive species throughout Europe, biosecurity will now be an important aspect of our daily activities.

At INVAS, we provide a range of products to help you improve biosecurity for your operations. We stock Virkon® Aquatic, a broad spectrum virucidal surface and equipment disinfectant. One of our wide range of portable and permanent disinfection stations will provide a biosecurity option to suit your organisation and its activities. Contact us in relation to your biosecurity needs and to discuss further options available to you.

Did you know?

Under the European Communities (Birds and Natural Habitats) Regulations 2011 it is an offence to “plant, disperse, allow or cause to disperse, spread or otherwise cause to grow” a wide range of non-native species that are listed in the Third Schedule of these Regulations.

The Cause

Many non-native species that have become invasive were introduced by collectors of plants in the 19th century.
Due to globalisation the issue has accelerated and many more species are hitchhiking on cargo and in ballast water. Garden centres are continuing to contribute to the problem by selling these plants as ornamental or as oxygenators for aquaria.

The Problem

Invasive weeds on land or in water have no natural controls, such as predator or pathogen control. This results in their rapid expansion across land and water, often resulting in significant disruption of the infested habitat and its residents. This can also result in serious loss to the local economy as angling and other leisure activities can be severely restricted.

What you can do

  • Always disinfect your boots, equipment, boats and trailers on leaving the water.
  • Encourage your co-workers or angling companions to disinfect.
  • Organise invasive species training sessions for your colleagues.
  • Report any plant, invertebrate, fish or animal that you might think is invasive to Invas Biosecurity
