Survey : CLIO/4/1970 (part of CEFAS Historic surveys)

This survey was undertaken by Cefas as part of the CEFAS Historic surveys;

Station and biological data collected during research surveys carried out by 
Cefas (formerly Directorate of Fisheries) in seas around the UK, mostly in the 
North Sea, since 1902. The survey hauls are not laid out systematically as a 
grid, as in current International Bottom Trawl Surveys (IBTS) and are widely 
distributed over (especially) southern and central North Sea areas. Gears and 
protocols were not standardised throughout, due to the long term nature of the 
series. Surveys took place in each season. Data are lacking for the periods of 
both World Wars. In some periods (e.g. the early 1900s), all species caught 
were recorded, whereas in other periods (e.g. 1920s-30s), only the key 
commercial species (e.g., Plaice, Sole and Cod) were recorded systematically. 
Note that some surveys targeted particular species (notably Plaice).

Survey took place between 17/02/1970 and 27/02/1970 on Clione

Management Strategy Evaluation toolkit for Ecopath with Ecosim (model output and technical report)

This dataset consists of output from a computer model that predicts responses 
of 69 functional groups from plankton to whales to changing fishing pressure. 
Scenarios are run using the newly built plug-in (see report) that allows for 
an assessment of the effect of model parameter uncertainty. The base model is 
the ICES key-run of EwE for the North Sea described here 
`http://data.cefas.co.uk/#/View/2847`_. Format of the data: Zipped csv files 
covering the hindcast period 1991-2013 (inclusive) with 20 year forecasts. 
Output includes annual average values for the whole North Sea: For both 
functional groups and fishing fleets: landings (tonnage and value, £), 
discards (tonnage),for functional groups only: biomass (tonnage) and fishing 
mortality (split by landings and discards), for fishing fleets only: fishing 
effort relative to 1990. Also identified are 'choke species' that lead to 
closure of fisheries. The report (pdf) describes the development of a tool for 
assessing the effect of model parameter uncertainty on the performance of 
management options simulated using an ecosystem model. It provides the 
rationale, description of methods and algorithms, and a step-by-step guide for 
users of the tool. While the interface of the tool is designed to be user 
friendly, the setup of input files and its application requires a thorough 
understanding of the parameterisation of Ecopath models, advanced experience 
with Ecosim and understanding of Management Strategy Evaluation procedures.

Area VII Haddock Discard Eliminations using Technical Measures 2014/15 - Fisheries Science Partnership

Following experimental work carried out in 2013, a twin-rig trawler, the 
Ilfracombe-based *Our Olivia Belle *(BD 277), was chartered to undertake 
further trials of a modified demersal trawl in August 2014 to look at 
selectivity in a mixed demersal fishery off south-west Cornwall. The primary 
aim was to improve the selectivity of the trawl to reduce discards of unwanted 
haddock with the least possible impact on the wanted catches of haddock and 
other commercial species. This is important in view of the future 
implementation of the landings obligation and associated catch quotas for 
species such as haddock. Following discussions with several Newlyn-based 
trawler operators, the decision was taken to investigate the effect of 
inserting square-mesh panels (SQMP) of 155 mm mesh into the top panel of the 
lengthener of an otter trawl. A twin-rig trawl, deployed as for normal haddock 
fishing, was used to compare the catches of modified and standard trawl nets 
in a series of tows on the fishing grounds off SW Cornwall.

Benthic State and Change in UK Marine waters. Irish Sea benthic sampling 2006-2007

Sampling of the biological and physical characteristics of 155 stations in the 
Celtic Seas, English Channel and the North Sea. This data is specifically from 
Irish sea samples collected in 2006-2007 and contains infromation on the 
abundance of macrofauna at each station.

Environmental variables quantified for each station included bathymetry 
(except North Sea and western Scotland), stratification, bottom temperature 
and a number of derived granulometric parameters (e.g., % silt, % gravel, 
sorting coefficient, skewness, kurtosis), together with modelled parameters 
such as bed tidal stress, wave stress, bottom temperature, a stratification 
index and satellite-derived surface chlorophyll a (mean values for 2002-07 
used). 

Estimates of the benthic productivity associated with such communities were 
also derived, for the first time, at this large spatial scale.
