The first invasive species in the Corrib, Roach has now had thirty years to integrate with other fish stocks in the lake.
In May 2007, Derek Evans the Irish Times angling correspondent reported that zebra mussels had been found in the stomaches of coarse fish in Ross Lake. Ross Lake is located west of Moycullen and is connected to the corrib via chain of lakes that terminates in Moycullen Bay. It is popular with coarse anglers from all over Europe.
Subsequent investigations showed that
An invasive species may be defined as an alien species whose intentional or unintentional introduction threatens native biodiversity.
An alien species refers to a species, subspecies or lower taxon, introduced outside its natural past or present distribution. It also includes any part, gametes, seeds, eggs, or propagules of such species that might survive and subsequently reproduce.
In the research world of invasive species, they are broadly divided into 2 main categories i.e terrestrial (land based) and aquatic (water-based) species. A variety of aquatic invasives exist in the freshwater and marine environment.
Download an APP (IFI-Invasies Species App) to help track the spread of invasives
Download and use a specially devised app to track the spread of invasive species. Take a picture of what you think might be an invasive, the picture will be geo referenced and if verified as being an invasive, its name and location will be added to the aquatic species map of Ireland which has been produced by IFI (Inland Fisheries of Ireland).
Lough Corrib is still free from several invasives that have already reached other parts of Ireland. One example is the Asian Clam (Corbicula fluminea). This species has already invaded the Upper Shannon, the Rivers Barrow and Nore. Please see ‘relevant links’ to learn more about this pest and about how you can avoid transporting it to the lake.
To date, Lough Corrib is infested with Zebra Mussels (a filter feeder) and with the aquatic plant Lagarosiphon major (the African Curly Leaved Water Weed). Japanese Knotweed (Fallopia japonica) has been noted growing along the banks of the River Corrib alongside NUI Galway.
The CAISIE Project was an EU Life+ funded initiative co-financed by the National Parks and Wildlife Service and co-ordinated by Inland Fisheries Ireland. The project commenced in January 2009 and concluded in January 2013. One of the outputs of this project was documentary about the threat posed to inland fisheries in Ireland by invasive species and the work of CAISIE which aims to find a range of control, containment and eradication strategies.
