CEFAS22-04 RFQ Marine benthic macroinvertebrate analysis of Lyme Bay disposal

Tender description

This request for quotation is for the processing of 30 sediment samples (10 stations with triplicate samples) to extract and identify all biota retained following sieving on a 1.0 mm capture mesh, as per the NMBAQC guidelines detailing extraction and identification protocols. In addition to this there is a requirement to ensure these data are audited as per the NMBAQC Own Samples protocol prior to submission to Cefas (Hall, 2019). http://www.nmbaqcs.org/media/1764/os686970_summary-report.pdf Enumeration, identification and biomassing to the lowest possible taxonomic level should be carried out following the NMBAQC Processing Requirement Protocol and Taxonomic Discrimination Protocol. Biomass (wet weight in grams to at least 4 d.p.) is required for all enumerable taxa. Balances must be serviced annually and a valid service certificate must be supplied with this tender. A single reference collection of all species/taxa identified should be returned to the Cefas laboratories in Lowestoft in an appropriate preservation liquid (i.e. 100% IDA or 70% IMS, 20% water and 10% glycerol). The reference collection should contain as a minimum the species name, name of identifier/ supervisor, station code, cruise code, date of collection and name of species identification verifier. A list of all taxa in the reference collection is also requested; in electronic form, with these details included. Notable taxa should be highlighted here such as non-native species and new or unusual records. Non-native species should be added to the Non-native Species Information Portal (NNSIP) (hosted on the Non-native Species Secretariat website, http://www.nonnativespecies.org/index.cfm?sectionid=81). The abundance and biomass data matrices should be in completed with, at minimum, the detail in the exemplar provided and, then sent via email to the above contacts following completion. All species names must be run through the WoRMS ‘Match Taxa’ tool so that all naming is current (http://www
