SAC Monitoring: Lamprey Monitoring for the Afon Cleddau (2012)

River lamprey (Lampetra fluviatilis), Brook lamprey (Lampetra planeri), and Sea lamprey (Petromyzon marinus) are listed in the Annex II of EU Habitats Directive (EU Directive on the Conservation of Natural Habitats of Wild Fauna and Flora 92/43/EEC) and 6 rivers in Wales are designated as Special Areas of Conservation (SAC) for this feature. The River Cleddau is one of the westernmost rivers in Britain and can be broadly divided into Eastern and Western arms. Assessments of species composition, distribution, abundance and size class composition are of particular interest as an indication of Condition Assessment. The sampling strategy for the monitoring programme for sea, river and brook lamprey followed the protocols developed for the LIFE in UK Rivers project, was aimed at undertaking a condition assessment for the population of brook, river and sea lamprey designated features for the second Habitats Directive monitoring reporting cycle (2007-2012). 12 sites in the Eastern Cleddau and 13 sites in the Western Cleddau, Pembrokeshire.

Lineage: Lamprey populations and condition assessment was previously carried out by CCW in 2003 (Harvey and Cowx, 2003) and 2005 (Campbell et al., 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 thee times whilst sub-optimal habitats were sampled once. The original data contains positive and negative samples. Confidence in this dataset is high.
