CEFAS26-68 Request for Quotation for Marine Benthic Macroinvertebrate Samples Processing

Cefas, Natural England (NE) and Northumberland Inshore Fisheries and Conservation Authority (NIFCA) have been working collaboratively to deliver a monitoring survey within Marine Protected Areas (MPAs) as part of the ongoing MPA programme. This survey aims to support Natural England’s monitoring objectives and provide robust evidence to inform conservation measures. Coquet to St Mary’s MCZ is an inshore site located along the Northumberland coast in the north-east of England. The site covers 192 km² of intertidal and offshore waters from near Whitley Bay in the south to near Alnwick in the north. As part of the MPA programme, NIFCA, NE and Cefas are planning to collect sediment samples within the site and in surrounding control areas using a 0.1m2 Day grab during a survey aboard the PV St Aidan planned for May 2026 (exact dates to be confirmed). Final sample availability will be confirmed in writing following survey completion. The survey aims to: 1. Detect temporal change in benthic community structure and sediment characteristics relative to previous surveys (Cefas 2016 and 2021). 2. Provide evidence on the effectiveness of current fisheries management measures in maintaining the subtidal mud feature in line with the site’s conservation objectives. 3. Provide information to support Natural England’s condition monitoring in the MCZ. The objective of the survey is to collect up to 52 Day grab samples (see Appendix 1 and Appendix 2). Samples will be collected both within the boundaries of the MCZ (25 samples), and outside the MCZ (27 sample). The macrofauna samples will be preserved in formaldehyde shortly after sampling, and all containers have both an internal and external label, clearly indicating the survey and station information. All work under this contract is subject to the successful completion of the 2026 Coquet to St Mary’s MCZ survey in May 2026. Cefas is initiating this procurement in advance to ensure timely analysis once samples become available. Shoul
