Freshwater River lamprey (Lampetra fluviatilis), Brook lamprey (Lampetra planeri) and Sea lamprey (Petromyzon marinus) Survey Data

River lamprey (Lampetra fluviatilis), Brook lamprey (Lampetra planeri), and Sea lamprey (Petromyzon marinus) are designated features of the River Usk and Wye Special Areas of Conservation (SACs). Assessments of species composition, distribution, abundance and size composition of larval lamprey (ammocoetes and transformers) populations in these river are of particular interest as an indication of Condition Assessment. The data was collected to help assess the conservation status of Lampreys in the Usk and Wye Catchments. This collation of lamprey data is made up of data collected by Countryside Council for Wales (CCW) and the Environment Agency Wales for CCW SAC monitoring reports or CCW Review of Consents reports. The collation includes information about species distribution, composition and abundance for river, brook and sea lampreys which are a designated (Annex II) features within SAC rivers in Wales. The majority of the data was recorded at the genus level and no distinction was made between river and brook lampreys. However for some historical data no distinction was made between sea and river/brook lampreys and these were recorded at the family level. This dataset comprises of a number of surveys entered into Recorder 6 which have been packaged for dissemination onto the NBN Atlas.

Lineage: Lamprey populations and condition assessments have previously been carried out by CCW in 2003 and 2005. The field survey was conducted in 2012 by Environment Agency staff using the standard electrofishing methodology. A condition assessment is made using the JNCC Common Standards Monitoring Guidance for Freshwater Fauna. Quantitative quadrat surveys were carried out in both optimal (very silty) and sub-optimal (more rocky) habitats. Electric fishing techniques were used inside a 1m2 quadrat to draw lamprey out of the silt rather than stunning and trapping them within the silt. Sampling of optimal habitats quadrats was done three times whilst sub-optimal habitats were sampled once. The original data contains positive and negative samples. Confidence in this dataset is high.
