The challenge ” Fishery Management” aims to construct the fishery data sets and information that will serve to quality assess, extract the synergies between and identify the gaps of the present datasets on fisheries in terms of landings, discard and by catch as well as in terms of spatial distribution of the bottom trawl fishing effort in order to evaluate changes in level of disturbance on the sea floor.

The final aim is to provide an overall picture of the trends over the years of landing, discard and bycatch by species.

 

Workflow

The workflow is following three major activities:

Activity 1: to search for upstream data to meet challenge requirements

Activity 2: to build and analyze data base, produce challenge outputs for GIS use

Activity 3: to deliver checkpoint information, and report assessment in results in the Literature Survey and Data Adequacy Reports.

Challenge_Fishery_Management

To fulfill the objective, available landing data from before and after the DCR came into force will be collected and pooled together in an appropriate format or other e-tools in order to provide the tables with mass and number of catches of species requested by the tender, with the highest possible precision and accuracy. In particular, as regards the data collected in the framework of DCR. The time-series will be as long as possible.

 

Team involved 

 

Data processing

  • Which input information is looked for, discoverable 

Data inputs necessary to deliver tables as requested the tender specifications are:

  1. Database on landings from the different partners / countries;
  2. Data from the EC – Data Collection Regulation (DCR) from the different partners / countries;
  3. Other data sources as pointed out in scientific publications expert group reports (STECF, GFCM and ICCAT) and grey literature regarding studies carried out before and after the DCR and supported by EC or MS about catches of fish, mammals, reptiles and seabirds.

Browse Data Source

  • Are data sets accessible ?

The Challenge will provide information on the data availability in a standardized way plus terms of access and use.

Availability of data sets will be checked as follows :

  • Cited in peer reviewed paper or grey literature but no info on how to access;
  • Information retrieved upon specific request to the data source;
  • Use of open search engines, searching by name either the data provider or the characteristics;
  • Search via reference catalogue (e.g. Emodnet, etc..).
  • How appropriate for use are the data ?

The Challenge will provide information on the data appropriateness in standardized way plus descriptive text of strengths and weakness regarding the appropriateness of upstream data used. It will include a rationale for non selection of unused input data.

 

Targeted products

The targeted products will be a set of series of excel spreadsheets reporting values by species and year and correspondent confidence limits plus Quality assessment indicators and reports .Tables of mass and number of landings of fish by species and year and mass and number of discards and bycatch of fish, mammals, reptiles and seabirds by species and year using as long as possible time series.
