## Summary

The procurement process undertaken by JNCC Support Co, a public authority within the central government of the United Kingdom, focused on trialling benthic eDNA sampling methods for marine biodiversity monitoring. The project, titled "Trialling Benthic eDNA Sampling Methods for Monitoring Marine Biodiversity," falls under the marine research services and monitoring and control services categories. The activities are primarily located off the North-West of Jones Bank Marine Conservation Zone, offshore from South-West England. This procurement is in its Award stage, having been completed as of 6th October 2025. The related contract was signed on 22nd September 2025, with an implementation period running from this signature date to 13th February 2026. The project involved obtaining samples for analysis to bridge knowledge gaps in offshore eDNA application, with a gross contract value of £42,750.

This tender presents significant opportunities for businesses specialising in genomic analysis, particularly those with expertise in eDNA techniques. SMEs like Applied Genomics Ltd, which was awarded the contract, are well-suited to compete in this field due to the precision and specialised skills required in environmental DNA analysis. This project not only seeks to enhance marine environment monitoring capabilities but also allows businesses to expand their service offerings in environmental research and technological innovation, ultimately fostering growth in sectors seeking sustainable and efficient biodiversity assessment tools.

## Notice

3. Project Background The RV Tom Crean will depart from Cork for the TC25035 survey on 9 September 2025 and return on 25 September 2025. Seventeen days of sampling will be carried out as part of the survey, focusing on data collection to support the assessment of potential fisheries management measures. The survey will gather data on the effects of reduced fishing pressure on the recovery of subtidal mud habitats, as well as of sea-pen and burrowing megafauna communities. North-West of Jones Bank MCZ is situated approximately 165 km offshore from the South-West of England. The site covers 399.14 km2 of continental shelf, and it contributes one of the largest areas of subtidal mud to the MPA network of all designated MCZs. For more information regarding NWJB MCZ please see https://jncc.gov.uk/our-work/north-west-of-jones-bank-mpa/. DNA and eDNA are increasingly utilised, cost-effective tools for monitoring biodiversity. Traces of DNA (e.g. from scales, faeces, skin, blood) left in the environment (e.g. water and sediments), called environmental DNA, are left behind by all organisms. Using molecular methods, such as eDNA metabarcoding, we can detect an organism's presence in the environment without directly observing it. eDNA techniques can provide high-resolution pictures of biodiversity from micro to macro scales and inform on assemblage composition and biological processes at reduced costs and time. Niskin bottles, metaprobes and sediment samples have been increasingly used in recent years to collect DNA from inshore marine waters, complementing existing traditional survey methods. However, application of these methods in offshore waters has been more limited. 4. Project Objectives As part of the offshore survey to North-West of Jones Bank MCZ, the primary research and development objective will be to trial three eDNA sampling techniques to fill significant knowledge gaps on the use of eDNA in offshore environments. To achieve this objective, the following research questions to be answered are: 1. Which benthic eDNA sampling methods are recommended for sampling offshore marine organisms based on the following factors? a. Quantity of DNA collected b. Quality of DNA collected 2. How do the following parameters compare among the benthic eDNA sampling methods? a. Species detected b. Species of conservation interest detected c. Species richness To answer these questions, JNCC plan to collect four eDNA samples using each of the three methods below, at four stations within the survey area. This will result in up to 48 eDNA samples plus six controls. eDNA source eDNA collection method Storage Sampling methods Water Sterivex filter 99% ethanol (volume tbc) Niskin bottles attached to a CTD from a depth 3 metres above the seafloor Water including sediment particles Gauze 50ml 99% ethanol Metaprobes attached to a towed camera sledge for 30 mins Sediment Sediment sample Frozen Sediment samples collected from a Day grab JNCC wishes to commission a contract to undertake this analysis of marine taxa eDNA in water and sediment samples collected on the TC25035 survey of NWJB. JNCC plan to collect a total of 54 samples. However, please note that the resulting sample number will depend on successful sampling delivery, which could be affected by factors such as weather. JNCC would like to use primers to test samples for the presence of marine vertebrates, fishes, invertebrates, meiofauna and bacteria. The successful contractor will undertake the analysis as set out below (Section 5) adhering to common standards. 5. Project Objectives: Detailed Tasks The tenderers should provide a quote broken down into the following elements: * Transport of 54 samples (48 eDNA samples plus six controls) from Cork, Ireland to the laboratory * Sample preparation and DNA extraction of 54 samples (48 eDNA samples plus six controls) * The per-sample analysis of: o 16 x niskin bottle eDNA samples plus two controls o 16 x metaprobe eDNA samples plus two controls o 16 x sediment eDNA samples plus two controls Using universal primers to target a full range of marine biodiversity such as: o Bacteria and archaea (e.g. marker 16S rRNA) o Meiofauna invertebrates (e.g. marker 18SSSU) o Invertebrates (e.g. marker CO1LB) o Fish (e.g. marker 12STele) o Vertebrates (e.g. marker 16SMV3) * Delivery of a final report, to include: o Introduction and aims o Methods o Results o Discussion o Recommendations for future offshore monitoring The methods section of the report should share sufficient detail for the study to be repeated. It should cover: * Clear field protocol detailing eDNA sampling and storage for method comparison and validation. * DNA extraction methods - including the names of kits if used. State how the DNA was quantified and discuss the quality of DNA extracted. * PCR amplification - specify the primers, PCR cycle conditions and reagents used. * Sequencing - detail how the DNA products were prepared for sequencing including reagents, primers and conditions. State how the DNA was quantified, and the model of the sequencing machine used. In addition, the methods should allow the reader to understand the confidence in the sequences obtained. * Bio-informatic processing: State in detail how the bio-informatic processing was completed, by specifying the steps taken. State any programs that were used. * State any reference libraries used, and if a custom database was created the rules used. * Where sequences are being used for taxonomic assignment, please explain the methods used to assign a species and why any reads may have been discarded. The results and discussion sections of the report should include the following: * The efficiency of DNA extraction and correct amplification of expected PCR products at each stage. * A discussion of any problems and how they were resolved, such as issues with PCR leading to a change of reagents or amplification conditions. * A detailed discussion explaining the results and confidence levels of the bioinformatic processing. * Detailed results, including statistical analysis of data, to address Questions 1 and 2 above. * To answer Question 2b, the results should include tables on species of interest, detected using each method. The list (to be provided by JNCC) includes UK BAP Priority Species, OSPAR Threatened and/or Declining Species, Annex II species, Species listed as Features of Conservation Interest (FOCI), and invasive non-native species.
