Database of European river lamprey (Lampetra fluviatilis (Linnaeus, 1758)) actual samples deposited in the A.N. Severtsov Institute of Ecology and Evolution

Study Extent

Geographic range - rivers of the Baltic sea drainage basins. Area – the European part of Russia. Freshwater ecoregion – Lake Onega – Lake Ladoga (FEOW ID 409), Southern Baltic Lowlands (FEOW ID 408), Central & Western Europe (FEOW ID 404).

Sampling

Seaward migrants were sampled by cone nets; upstream migrants and mature adults by minnow traps, and fishing nets

Quality Control

The dataset is based on the deposited in the collection of lamprey specimens. The taxonomic status was estimated according the key for lampreys (Renaud, 2011). Physical coordinates of sampling sites are obtained from GPS-navigators or from the Google maps.

Method steps

1. Gathered specimens and samples were preserved in formaldehyde (4%) or ethanol (genetic samples), delivered to the Institute of Ecology and evolution. Taxonomic status is estimated by basic external features (mainly dentition). Samples are labeled as IEE and numbered. The labels are stored in the local database “Lampreys of Russia”.
