The primary objective of the programme is to improve the data collection on sprat and sardine in the South west of England in support of the stock assessment, by means of the continuation of a self-sampling programme which was first initiated through collaboration between the fishing industry (the Cornish Sardine Management Association (CSMA), fish processors and fishers) and Cefas focusing on the sardine resource in 2017-2018. After the success of the first year, the sardine self-sampling programme was continued in 2018-2019 and expanded to the sprat fishery. An industry-led acoustic mini survey for sprat (focused in Lyme Bay area) was carried out to determine if the Cefas Pelagic fish and Ecosystem survey in the Eastern Celtic Sea (Peltic) was underestimating biomass for small pelagics in the shallow coastal waters. In 2019-20, although the focus of the FSP project was on sprat, support for the third season of self-sampling by the sardine fishery was continued. Ultimately, the main aim is that the self-sampling programme for both the sprat and sardine fisheries can run autonomously and will (continue to) contribute reliable fisheries dependent data to the assessment process for both stocks. This year (2020-21) new technology was added to the fourth self-sampling season for sardine, and the third season for the sprat fishery. The first technological innovation added to the programme was the development of a phone app in collaboration with the company Applied Satellite Technology (AST; `www.theastgroup.com/uk`_) which would facilitate the data collection and submission aboard the participating fishing vessels. The second innovation was the installation of temperature and pressure tags (sensors) onboard the fishing vessels, to acquire data on the environmental conditions in which they operate. This was a question suggested by the industry to improve understanding of seasonal dynamics and behaviour of the relevant pelagic fish populations. The steps towards the digitalization of the programme were intended to be the final steps toward the programme running autonomously, with the minimal Cefas intervention. The available time series for both sprat and sardine length data from the fishery were of relevance this year as they were important in the stock assessment review, being used for the inter-benchmark for sprat in ICES division 7de (ICES) and the first full benchmark for sardine in division 7. .. _`www.theastgroup.com/uk`: http://www.theastgroup.com/uk Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk originator Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk custodian Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk distributor notPlanned Fish Biota abundance, biomass and diversity Fisheries SeaDataNet P03 parameter discovery vocabulary 2011-03-25 revision Species distribution GEMET - INSPIRE themes, version 1.0 2008-06-01 publication Water column SeaVoX Vertical Co-ordinate Coverages 2010-05-18 revision Marine Environmental Data and Information Network MEDIN metadata record availability 2012-01-11 publication data.gov.uk MEDIN metadata record availability 2012-01-11 publication otherRestrictions noLimitations otherRestrictions **Publicly available data licensed under the Open Government Licence v3.0 (`https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/)`_ – Please note the applicable attribution statement is as follows: ‘includes Crown copyright, Cefas 2022'** .. _`https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/)`: https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/ English biota -7.00 -2.50 49.50 51.50 2020-08-01 2021-01-31 Binary Unknown https://data.cefas.co.uk/view/21397 Cefas Data Portal download The Cefas Data Portal contains metadata records and data sets available to download and connect to in support of our commitment to open science.

Fishers fill logbooks with total catch and bycatch information for everyday fished, and record length measurements for a subsample of target species (sardine or sprat) of trawls during the season. A “bucket sampling protocol” is followed (for more info check: `https://data.cefas.co.uk/view/19212`_), where the fishers extract a subsample from the catch using a standardized bucket. The “sampling days” are determined by random calendars that Cefas provide every year to the fishers. Processors provide individual length and weight information for at least 50 individuals per species per month. All the data collected is combined and contributes to build a time series which will ultimately contribute to the stock assessment of sardine in ICES area 7. .. _`https://data.cefas.co.uk/view/19212`: https://data.cefas.co.uk/view/19212 MEDIN 3.1.1
