2001 Castro-Longoria, E. Southampton Water Acartia tonsa records

Eggs produced by four Acartia species from the Solent-Southampton Water estuarine system were examined. Acartia tonsa produced two morphologically distinct types of eggs, which were identified as subitaneous and diapause. Diapause eggs from this species were spiny while the subitaneous form had a relatively smooth chorion surface; a second subitaneous egg was produced by A. tonsa, which had significant spine extensions on the surface. Acartia margalefi, A. discaudata, and A. clausiproduced only smooth eggs, which were identified as subitaneous. Observations under scanning electron microscopy (SEM) revealed consistent interspecific variations in the texture of the chorion surface of both subitaneous and diapause eggs in all species.

2011-2018 - Sussex Inshore Fisheries and Conservation Authority (IFCA) Trawl fish surveys

Sussex IFCA has historically undertaken fish surveys throughout the district in order to monitor juveniles of commercially important species and to further understanding of the ecosystem health, particularly within Marine Protected Areas. Between 2011 and 2018, the Authority also undertook beam trawl surveys across Chichester Harbour and Rye Bay. Where possible, fish are identified to species level, although in some cases species are recorded at genus level. In each sample, 50 individuals of each species are measured in total length, with any additional being counted. Once recorded, fish are returned alive to the sea.

2006 Kerckhof et al. North Sea record of Rapana venosa

An invasive gastropod, the veined whelk Rapana venosa, was first recorded in July 2005 in the Dutch part of the North Sea, and in September 2005 in the central southern North Sea (the wider Thames estuary). Both shipping activities and natural dispersion from the nearest population in France (Quiberon, Brittany) are possible modes of introduction of R. venosa to these sites. The possible effects of R. venosa in the North Sea remain uncertain, but if established, this invasive species could become a severe competitor for the native whelk Buccinum undatum. As R. venosa is known as predator on bivalves, an impact on local aquaculture activities (on e.g. blue mussels and oysters) is also possible.

1991 University of Southampton, Wytch Lake and Channel, Dorset, Benthic and sediment box corer survey

All these records relate to "Jensen, Collins, Ovenden (1991)  - Benthic survey of Wytch Lake and Channel, March 1991" A copy of the report is held at BP Exploration Operating Company Ltd, Wareham, Dorset.
     This survey was carried out following a spill of water-soluble degreasing agent on 8th March 1991 in Wytch Lake, a narrow creek off Wytch Channel. This latter channel opens into Poole Harbour. Shortly after the spill the sediments of the Lake and Channel were sampled at 14 stations. The Department of Oceanography, University of Southampton, was commissioned to report on the benthic infauna and sediment granulometry of the samples. Thirteen stations were sampled in Wytch Lake and Wytch Channel plus a control station (Station 15) in Redhorn Lake. Samples were taken during second high water using a small box corer. The surface area sampled at each site was 0.0225 m sq. It was not possible to sample site 10. Station 15 was selected as a control station, but as it contained a number of species not recorded at Wytch Lake and the sediment granulometry was markedly different, it was not used as a comparison for this assessment. Samples were sieved using a 500 micrometre sieve. N.B. Co-ordinates of stations not given, so locations estimated from schematic map of sampling sites in the report.

2012 Eastern Inshore Fisheries and Conservation Authority (EIFCA) The Wash Crassostrea gigas records

Within Eastern Inshore Fisheries and Conservation Authoritys (Eastern IFCA) district a variety of inshore fisheries are operated by local fleets and individuals. These include nationally important shellfish species including cockle, mussel, shrimp, crab and lobster, in addition to several finfish species. The district also supports a wealth of important natural features that are protected under a suite of UK and EU designations (Site of Special Scientific Interest, Special Protected Area, Special Area of Conservation (SAC), Ramsar site), which collectively form a network Marine Protected Areas. It is also likely that that several new Marine Conservation Zones will be designated within the district during the next three years. To ensure the Districts sea fisheries resources are managed in a sustainable manner, without having an adverse impact on the environmental features, Eastern IFCA conducts stock assessments, fisheries impact research, environmental monitoring and habitat mapping. A large proportion of these activities are conducted in The Wash in order to support the Authoritys management of The Wash Fishery Order 1992, which oversees the major molluscan fisheries in The Wash. This report details the main research activities conducted by Eastern IFCA during 2012.

2004 Scottish Natural Heritage (SNH) Loch nam Madadh marine features Site Condition Monitoring inaugeration survey

The purpose of this study was to initiate Site Condition Monitoring (SCM) of the Loch nam Madadh SAC qualifying features: large shallow inlet and bays, saline lagoons, intertidal and sublittoral reefs, intertidal sediment flats, and subtidal sandbanks. This survey was done to: (1) establish a baseline biological data set that would facilitate the assessment of the condition of the habitats in the future; and (2) to allow a judgement to be formed on the current condition of these habitats. The main approach taken to achieve these objectives was to perform a drop-down video survey of the biotopes of the SAC, concentrating on the sublittoral sediments, to characterise the infauna of the main sediment biotopes by means of grab and core sampling, and to perform surveys of the epibiota of rock, lagoon, maerl and Zostera biotopes along relocatable transects.

Benthic infaunal abundance and biomass from Belfast Lough dredge disposal monitoring operations 2017 and 2018

This dataset contains information on benthic infaunal abundance and biomass from sediment grabs and video footage from off the Copeland Islands in Belfast Lough in late 2017 and early 2018 on the RV Corystes. This survey was carried out to describe the species and seabed habitats within a 0.5NM buffer zone of a dredge disposal site. The survey was carried out pre and post operation to allow the potential impacts to be investigated. In total there were 29 grab samples taken and analysed and 4 video tows carried out and analysed. Particle size analysis (PSA) and Carbon and Nitrogen analysis were also carried out on the sediments from the grab samples. All grab samples contained fauna species with the most abundant being Balanus cretanus and the most frequently recorded being Sabellaria spinulosa. The most frequently recorded species on the video tows were Spirobranchus triqueter and Balinidae.

2011 - 2015 North Western Inshore Fisheries and Conservation Authority (NWIFCA) Sabellaria alveolata surveys

In 2011 the north Western Inshore Fisheries and Conservation Authority began to complete surveys of intertidal Sabellaria alveolata (honeycomb worm) reefs in the district. This survey technique was developed initially to assess the reef on Heysham Flat as a tool to investigate the percentage cover and health of Sabellaria aveolata reef, to provide datasets to inform mussel management and to provide data to Morecambe Bay EMS Management Group on condition of the reef. This reef was surveyed annually from 2011-15. In addition this survey was used in other areas, particularly at Dubmill Point in Cumbria. The surveys recorded the percentage cover of S. alveolata as well as other ground cover types and classified the form and health of the growth.
     Evidence from the annuals surveys showed that there was continuous competition for space on the cobble and boulder reef between substantial mussel settlements and the worms, both of which proved to be ephemeral in nature. This competition was found to be the main driving force behind the health and distribution of the Sabellaria alveolata. Observations continue to be made on this relationship during regular mussel inspections carried out for fisheries management purposes.
