SAC Monitoring: Lamprey Monitoring for the Rivers Tywi, Teifi and Cleddau (2004-2005)

River, Brook and Sea Lamprey are designated (Annex II) features of the Tywi, Teifi and Cleddau River Special Areas of Conservation. Assessments of species composition, distribution, abundance and size of these species 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 Tywi, Teifi and Cleddau Special Areas of Conservation. Monitoring of the status of lampreys is required to comply with the reporting requirements of the Habitats Directive. A total of 112 sampling sites across the River Tywi, Teifi, Eastern and Western Cleddau were sampled of which 77 have positive records for either River or Brook Lamprey.

Metadata Language: English

Lineage: The sampling strategy for the monitoring programme for sea, river and brook lamprey followed the protocols developed for the LIFE in UK Rivers project (Harvey and Cowx, 2003). 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 thee times whilst sub-optimal habitats were sampled once. The original data contains positive and negative samples.
