2017 Cornwall Inshore Fisheries and Conservation Authority (IFCA) Fal Oyster Survey

Cornwall Inshore Fisheries and Conservation Authority (IFCA) conduct annual dredge surveys within the Fal Oyster Fishery since taking over management of the fishery in 2014.  The purpose of the survey was initially to assess the distribution and abundance of native oysters (Ostrea edulis) within the Fal Fishery management area in the River Fal, Cornwall. Since 2016 the survey has been developed to also assess queenies (queen scallop, Aequipecten opercularis; variegated scallop, Mimachlamys varia) distribution and abundance. Slipper limpets (Crepidula fornicata) were recorded at each site using a SACFOR style scheme. 
     The aims of the survey were to investigate the relative abundance and distribution of native oysters (O. edulis) and scallops (queen scallop, A. opercularis; variegated scallop, M. varia) within the Fal Oyster Fishery. The distribution of substrate types across the fishery were also recorded at each site and species of bycatch were recorded across the survey area as a list of species present. 
     In 2017, a total of 80 sites were completed and a total of 1481 oysters and 2952 scallops were recorded. The analysis was done by Geographic Areas; Harbour, Outer Harbour and River.

2012 University of Plymouth Falmouth towed underwater video maerl and associated epifauna survey

This data set comprises of marine epibenthos and endobenthos (approx. 370 identified taxa derived from Algae, Annelida, Arthropoda, Bryozoa, Chordata, Echinodermata, Hemichordata, Mollusca, Nematoda, Nemertea, Phoronida, Porifera and Sipuncula), associated with maerl beds in Falmouth Harbour, UK quantified between 2011 â 2013 using a towed underwater video system and hand cores taken by SCUBA divers. Additional data on sediment  (organic content and particle size) and the porosity of maerl found at the sites are also provided. Surveys were conducted to assess the extent, distribution and species composition of maerl bed habitats within the harbour in response to proposed dredging activities to deepen the shipping channel. To establish the location and extent of maerl beds and quantify the abundance of epifauna transects were undertaken using a high definition towed underwater video system. Towed video surveys took place in November 2011 and February 2012 and transects were approximately 200 x 0.5 metres. Core samples collected by divers September - November 2012 and July - August 2013 were used to further assess habitat quality and species distribution by quantifying the abundance of infauna and analysing organic content, particle size and maerl structure.

2022 Cornwall Inshore Fisheries and Conservation Authority (IFCA) Fal and Helford SAC Drop Down Video Maerl Habitat and Classification Survey

Cornwall Inshore Fisheries and Conservation Authority (Cornwall IFCA) carried out a survey between May and July in 2022 of the maerl feature of the Fal and Helford Special Area of Conservation (SAC). The aim of the survey was to get a better understanding of the varying types of maerl habitats present including: dense maerl (live and dead or dead), maerl sediment (live and dead or dead), sparse maerl (live and dead), scattered maerl (live and dead), maerl veneer (live and dead, static or live and dead, mobile) and areas of potential maerl which lack detail, and to provide and updated extent and distribution map within the Fal and Helford SAC. There were two parts to this survey and the current report details the second part. The first part consisted of an initial side-scan sonar survey in the Fal and Helford SAC, which was carried out by Cornwall IFCA in 2020 and 2021 (Sturgeon et al., 2021). The initial survey gathered acoustic data within the SAC, focusing on Falmouth Bay and covered an area from Pendennis Point to the Helford River out to the Fal and Helford SAC boundary from Zone Point towards Manacle Point. This second part uses the acoustic data gathered in part one to identify transitions between different acoustic signatures, with the aim of verifying habitat types represented by the given acoustic signals, using drop down video and stills. The survey is reported on by Jenkin et al., 2023.

1972 - Ongoing Dove Marine Laboratory Benthic Station M1 (North Sea) Time Series Data

Initiated in 1972, as long term monitoring with station P. M1 was the central station at a historic sludge disposal site in the Central North Sea, approximately 10.5 km away from the English North - East coast, with a depth of 55 m and a muddy sandy sediment. In 1972 and 1973 bimonthly (20 replicates) sampling occurred with sampling decreasing to September and March annually with 5 replicates taken at each occurrence. A 0.1 m2 Van Veen grab was used to collect samples passed over a 0.5 mm sieve and taxon abundance recorded per metre squared (Buchanan and Warwick, 1974). Community stability was seen in the period between 1974 and 1980, which was lost in 1980 - 1983. Changes in species ranking and increases in total numbers and biomass during the latter period.

2008 Mineur et al. UK west coast records for Bonnemaisonia hamifera

It has traditionally been considered that areas with high natural species richness are likely to be more resistant to non-indigenous species than those with lower numbers of species. However, this theory has been the subject of a debate ove rthe last decade, since some studies have shown the opposite trend. In the present study, a macroalgal survey was carried out at 24 localities in Northern Ireland and southern England, using a quadrat approach in the lower littoral. The two opposing hypotheses were tested (negative versus positive relationship between native and non-indigenous species richness) in this marine environment. The effect of the presence of âimpactsâ, potential sources of disturbance and species introduction(e.g. marina, harbour or aquaculture), was also tested. A positive relationship was found between the number of non-indigenous species and the native species richness at the three different scales tested (quadrats, sites and localities). At no scale did a richer native assemblage appear to restrict the establishment of introduced species. The analyses revealed greater species richness and different community composition, as well as more non-indigenous species, in southern England relative to Northern Ireland. The presence of the considered impacts had an effect on the community composition and species richness in southern England but not in Northern Ireland. Such impacts had no effect on the non-indigenous species richness in either area.

Cattewater Wreck Archive

The Cattewater Wreck was discovered in 1973 during channel dredging in the Cattewater, Plymouth, Devon. The site was the first wreck to be designated by the UK Government under the 1973 Protection of Wreck Act and is believed to be an unidentified armed merchantman of the first half of the 16th century.
     The site was partly excavated between 1975 and 1978. Most of the site documentary archive and much of the material archive were later deposited with the Plymouth City Museum and Art Gallery.
     The Cattewater Wreck Archive Project aimed to improve the long term care and management of the Cattewater Wreck Excavation Archive held by Plymouth City Museum and Art Gallery (called the City Museum from now on). The Project was grant funded by English Heritage's National Heritage Protection Commissions Programme (Project Number: 5439 MAIN), under the provisions of Section 45 of the Ancient Monuments and Archaeological Areas Act 1979.
     The main objective of this part of the Project was archive consolidation; a formal audit and indexing of the documentary archive and all associated artefacts to create a formal record of the present archive. A secondary objective was the improvement of the physical storage of the archive to better meet modern physical collection management standards.

2013 onwards, Sussex Inshore Fisheries and Conservation Authority (IFCA), Hastings, underwater video project

Sussex Inshore Fisheries and Conservation Authority (IFCA), funded by Natural England and in collaboration with the University of Brighton and Hastings Fishermen's Protection Society (HFPS), used underwater video footage to inform the seabed habitat near Hastings, including the rMCZ Beachy Head East. Simple underwater video cameras and digital video recorders were given to 9 of the Hastings fishermen under the management of HFPS. When the weather conditions, water visibility and fishing practice allowed, the cameras recorded geo-referenced 5 minute long videos of the seabed. The videos were/will be uploaded onto YouTube and be publicly available. The positions of the videos will be mapped by the University of Brighton. The videos will be viewed by local students using an education pack and ID guide tailored for primary to undergraduate levels. Habitat and biological information will be extracted and mapped. This project, through a participative approach, aimed to deliver a programme of work which enhanced the quality and management of the marine environment off the coast of Hastings. It has supported a better and shared understanding of the marine environment in the shallow coastal seas off the Hastings Coast and facilitated local decision-making to support sustainable fishing, which is better adapted to local context and meeting real needs.
