2010 NatureScot survey of Didemnum vexillum and other invasive species in South West Scotland

The aim of this survey was to determine the presence or absence of the invasive marine
     non-native D. vexillum on the south-west coast of Scotland. The first survey involved a
     series of rapid assessment surveys of those marinas and harbours thought to be most likely
     at risk from establishment (e.g. those in the Clyde). This was followed up by additional
     surveys of artificial and natural substrates in the vicinity of Largs Yacht Haven. The results of
     these surveys will inform SNH’s policy for dealing with this species, as well as the wider UK
     policy for response. Twelve locations, including ten marinas and two harbours on the west coast of Scotland
     (Figure 2.1; Table 2.1) were surveyed for D. vexillum between 1 and 5 February 2010
     following a similar method described in Ashton et al. (2006) and the method adopted by the
     Marine Biological Association UK in on-going surveys for this species in England (J. Bishop,
     pers. comm.).

UK Marine Ornamental Trade: Species-Level Import Records on Corals, Invertebrates, and Fish in 2018 and 2019

The dataset provides species-level information, as declared by the exporter,
 for marine ornamental species that were imported into the UK during select 
periods in 2018 and 2019. The study was undertaken to support the 
provision of higher resolution data on the UK’s marine ornamental trade at a 
Convention on International Trade of Endangered Species of Fauna and Flora 
(CITES) technical workshop on the conservation and management of marine 
ornamental fish (Decision 18.296). The dataset provides a snapshot in space 
and time of the UK's marine ornamental import trade and should be interpreted 
as such.

Experimental results of trials to assess non-native fish impacts on the diet and trophic position of native pond fishes using stable isotope analysis in outdoor artificial ponds

These data derive from experiments carried out during the spring and summer 
months of two successive years (2014 and 2015) in outdoor experimental ponds 
previously situated in East Sussex. The aim of the experiments was to 
determine whether or not introduced non-native fish species have an adverse 
impact on the diet and trophic position of native pond fishes. The 
experimental set up was more or less identical in both years, the study 
species in 2014 being the North American centrarchid (freshwater sunfish), 
pumpkinseed Lepomis gibbosus, whereas in 2015 the study species was the 
cyprinid fish native to Continental Europe, the sunbleak Leucaspius 
delineatus.

Plankton Imager (Pi-10) Meta data collected on RV Cefas Endeavour

Plankton Imager (Pi-10) data collected during RV Cefas Endeavour surveys. Data 
are images, separated by ten minute bins, and may be either unzipped, or 
zipped as tar files for that ten minute bin (zipping is a setting that can be 
turned on/off by the plankton imager acquisition software). Each image is 
directly named with the instrument ID, datetime and GPS data are embedded in 
the file metadata EXIF as decimal latitude longitude. These data provide an 
overview of where, when and how many images were captured by the plankton 
imager. Each row represents a 10-minute bin of images. The raw image data are 
stored on azure. The ‘BLOB’ column in the data indicates which folder within 
the azure container the data are stored. The HITS column indicates the number 
of images within that ten-minute bin and the MISSES column indicates the 
number of images not stored (e.g. due to date rate). The MISSES are needed to 
resolve abundance data in much the same way as splitting a physical plankton 
sample. Note, older data on an earlier prototype are available on request.

The deployment of the Pi-10 is continuous and these data are updated every 3 
months.

Particle tracking model output simulating floating marine litter in the Bay of Bengal, 2018 to 2019

These data are particle positions and dates/times which are output from an 
OceanParcels particle tracking model simulating likely pathways of floating 
marine macro-litter in the Bay of Bengal between 1st June 208 – 30th 
September 2019, saved as NetCDF files. The model incorporated advection due to 
ocean, wind, and Stokes drift velocities, horizontal diffusion, and particle 
beaching behaviours. Two different hydrodynamic data sets were used to force 
the particles’ trajectories: a high-resolution ocean velocity hindcast (ROMS – 
Regional Oceanic Modelling System) and a lower-resolution dataset which 
included data assimilation (CMEMS - Copernicus Marine Environment Monitoring 
Service). Sensitivity tests were run to determine whether hourly or daily 
forcing resulted in significantly different particle end locations and 
validation simulations were run to compare with undrogued drifter tracks for 
the same period and region. All model output is stored in NetCDF files. This 
is data to accompany a manuscript submitted to Ocean Science entitled 
‘Monsoonal influence on floating marine litter pathways in the Bay of Bengal’ 
(Preprint: `EGUsphere - Monsoonal influence on floating marine litter 
pathways in the Bay of Bengal`_). These experiments aimed to determine 
source-to-sink connectivity between countries surrounding the Bay of Bengal.

International (ICES) and national (UK) fish stock and shellfish stock data from 2021 assessment year

The dataset collected includes assessment output relating to the years from 
1905 to 2021 inclusive for annual estimates of the following variables for 
each stock: the annual recruitment estimate; the stock size (spawning stock 
biomass); landings (tonnes of fish brought to shore); catches (tonnes of fish 
caught at sea); fishing pressure (a fishing mortality rate); the target 
fishing mortality that will achieve maximum sustainable yield in the long term 
(Fmsy); upper and lower range estimates for Fmsy consistent with multi-annual 
plans and ICES advice; a threshold for spawning stock biomass (MSYB trigger), 
below which fishing mortality should be reduced below Fmsy, following the ICES 
advice rule, to avoid reduced reproductive capacity; a lower limit threshold 
for spawning stock biomass below which there is a high risk of reduced 
reproductive capacity (Blim). The stock assessment data for fish and shellfish 
stocks of UK interest is used to assess indicators of reproductive capacity 
(based on spawning stock biomass) and fishing pressure (based on fishing 
mortality). The applicable location for these data differ by stock, but are 
relevant to UK stock areas in the Celtic Sea / North Sea / wider North East 
Atlantic / Arctic region.

Seawater temperature records for the UK Shelf - 14 - Intensive plankton surveys off the north-east coast of England in 1976

This dataset has been extracted as part of an exercise to assemble "all" Cefas 
Temperature Data and publish it in a Data paper. It is one of 17 Cefas data 
sources assembled.

A series of 12 cruises was carried out in 1976 by DFR staff to investigate the 
distribution, abundance, mortality and main predators of planktonic fish eggs 
and larvae of important commercial fish species (e.g. plaice, cod). The 
cruises secondary aims included the investigation of phytoplankton standing 
stock (via measurements of chlorophyll concentration, phytoplankton size and 
abundance) and of zooplankton biomass.

Plankton samples were collected at each site on a planned survey grid. These 
data consist of numbers of macroplankton from 8 of the samples collected from 
an area off the North East coast of England, along with associated positional 
data and volumes filtered

Measurements of surface water temperature and salinity, and bottom 
temperature, were carried out at each sampling station on a planned survey 
grid (see below). Samples for the analysis of dissolved inorganic nutrient and 
chlorophyll concentration were also collected at the surface at each sampling 
station.

All the hydrographic observations were made from the vessels (RV Corella and 
Clione). Surface water temperature was monitored through a stainless–steel 
ship–board pumping system. The pump had an intake 4 m below the water surface 
and delivered sea water to sensors set up in the ship’s laboratory. The 
temperature sensor (as well as the salinity, pH, dissolved oxygen and 
transparency sensors) was mounted in a Perspex box though which the pumped 
water flowed continuously.

The measurement of temperature at the “bottom” at each sampling station was 
obtained from the chart records of the electronic depth gauge and thermistor 
sensors mounted on the plankton sampler.

The data collected during these cruises was presented in the ‘Fisheries 
Research Technical Report’ n. 86 by Harding and Nichols in 1987. The original 
log books from these cruises are in the Cefas plankton physical archive; some 
of these log books (e.g. containing plankton and icthyoplankton data) were not 
digitised (because not relevant for the project).

Young Fish Survey Data 1981 to 2010

Total numbers of individual fish identified during the Cefas Young Fish Survey 
(YFS) which ran from 1981 to 2010. The survey deployed a light 2-meter beam 
trawl to survey inshore locations for small / young fish around the British 
Isles, predominantly along the south and east coasts. Total numbers of fish 
(identified to species or if not to the highest taxonomic level) were recorded 
at each station, and were measured in the majority of cases. The surveys were 
primarily undertaken to evaluate the abundance of juvenile sole and plaice, as 
well as providing further information on the abundance of other species of 
fish. Alongside the main 'Young Fish Survey Data 1981 to 2010' data table are 
three further data tables marked as 'YFS_DWC' which give the same data in 
EventCore format and a readme file which describes historic versions of 
metadata which this record has replaced.

Eastern Irish Sea Razor Clam Survey 2009/10 - Fisheries Science Partnership

The fishing vessel Lord Sam ll was chartered to carry out a survey of razor 
clam populations on the Cumbrian coast. The aim of the survey was to establish 
whether a commercially viable stock of razor clam existed in this area. The 
survey was delayed by inclement weather, but was eventually completed in 
February 2010.

The Seafish/Cefas experimental water-jet dredge was employed north of Walney 
Island, but there were problems in deploying the gear safely. Those problems 
added to the sea-time lost through poor weather. In all, 34 dredge deployments 
were made, but at only 26 of these did the dredge fish successfully.

Where the dredge did work well, good catches of the razor clam Ensis siliqua 
were taken; up to 17 kg in a 10-min haul, although the average catch was ~5kg. 
The razor clam caught covered a wide size range and young animals from at 
least two year classes were present, suggesting that successful recruitment is 
a regular occurrence in the population. The adult population had a modal size 
pf 185 mm shell length.

The highest biomass in by-catches was contributed by the heart urchin 
Echinocardium cordatum., Several clam species, two possibly with commercial 
potential, were found regularly.
