European brook lamprey (Lampetra planeri) fish species information

Scientific Name
Lampetra planeri

Common Name
European brook lamprey

Biology
Found in the lowland, piedmont and montane zone in clear, well oxygenated brooks. Lives exclusively in freshwater; in middle and upper reaches of small streams and rivers, occasionally in lakes. Larvae lie buried in the substrate while adults live in the open water. Larvae of this species can serve as mid-term bio-indicators. They live in detritus-rich sands or clay sediments. Filter feeding larvae, non-feeding adults. Reproduction takes place upstream, from April to May. Because of its small size and the mediocre quality of its meat, it is rarely fished. The larvae are utilized as bait.
