Brook Lamprey

Brook Lamprey Lampetra planeri  are the smallest of the Lamprey species, measuring only 10 – 15cm. They are an eel shaped fish, with sucker-like mouth instead of jaws.  Whilst they are an EU protected annexed species, they are widespread in Duhallow’s rivers and streams. They have a short life cycle of 3 – 5 years, starting with their juvenile phase (ammocoetes) when they eat detritus and other organic matter on the riverbed.
