The EU Life+ funded Caisie project and Inland Fisheries Ireland (IFI) recently highlighted the importance of carrying out biosecurity measures after leaving waters infested with the Asian clam in order to prevent their spread to uninvaded water systems.  This is of particular relevance during the summer period when warmer water temperatures allow the clam to [...]

The Asian clam (Corbicula fluminea) is a most unwelcome recent addition to the fauna of Irish rivers and lakes. This bivalve mollusc is regarded as one of the most notorious aquatic invasive species in the world. The Asian clam was first recorded in Ireland in the River Barrow near St Mullin’s in April 2010.  Subsequent [...]

Aquatic Invasive Species (AIS) and fish parasites or diseases are readily transferred from one water body to another on diving gear, boats and protective clothing. These can be very damaging to resident fish stocks, the aquatic habitat and the general environment. In order to ensure that invasive species and fish diseases are not inadvertently transferred [...]

In April 2012 staff from IFI in association with the EU Life+ CAISIE project supervised trials using a cockle harvester to remove the invasive Asian clam (Corbicula fluminea) from a section of the river Barrow below St. Mullins. The Asian clam, a native to southern and eastern Asia, Australia and Africa, was first [...]

Press Release March 16th, 2011.
Non–native aquatic invasive species are now an unwelcome feature in many sections of the Grand Canal and Barrow navigation. The abundant growth of some of the invasive plant species can fill the water channel and make conditions difficult for navigation, angling and other water-based pursuits. The aquatic weed control methods operated by [...]

Inland Fisheries Ireland requests your support in looking out for this threat in any catchments that you visit.
The Asian clam (Corbicula fluminea) is an invasive bivalve species that has spread rapidly in lakes, canals, streams, rivers and reservoirs throughout Europe & North America.
The species is known to aggressively outcompete native invertebrate communities, limit phytoplankton biomass [...]

Discovery of the Asian Clam, (Corbicula fluminea) in Ireland.
The presence of an established population of the invasive Asian clam at St. Mullins on the River Barrow was confirmed following reports made to the CFB and the CAISIE project team. The team responded by carrying out a scientific survey in the area to investigate the extent [...]

Press Release    21/04/10
[update: Central Fisheries Board, Invasive Species Rapid Response, Alert!]
A new aquatic invasive species, the Asian Clam (Corbicula Fluminea) has been found in the River Barrow in Co. Carlow. The identity and status of this species was confirmed by Dr Joe Caffrey the Central Fisheries Board expert on aquatic invasive species.
The species which [...]

As most of the fish in Ireland were introduced by man throughout the history of the country many fish species could be regarded as invasive. Those which are well established are considered to be naturalised species having reached some sort of equilibrium in the environment.
Those fish which are still considered invasive species due to their [...]
