World list of seaports. In its 2021 version, the repository includes 13709 ports for 187 countries. The list of seaports has been drawn up on the basis of the information available in the European reference system of places used in the framework of the Common Fisheries Policy and, more particularly, by the Electronic Recording and Reporting System (ERS), the list of ports identified by the UNECE (2021-1). An assessment of the infrastructures present along the coastline made it possible to identify other ports that were not listed. Each geographical position has been verified with Google Earth in WGS84. Each port is associated with information relating to the country (ISO 3 coding), the UNECE or ERS 5-character coding, the name, the geographical position in WGS84 (latitude and longitude), the status of the port indicating whether it is referenced by Unece (UNECE), by the EU/ERS (ERS) or by both (UNECE/ERS) In case the port is not referenced by UNECE or ERS, the status is N/A. For French ports, the reference system integrates the ports of the French overseas departments and territories with the national codification. Inland ports have also been integrated in 2021.

SACROIS is a data crossing algorithm that produces professional fishing activity data series (validated, consolidated and qualified production and effort data) for the vessels registered in the Community Fishing Fleet (CFP) file. SACROIS selects the best of the available information sources to produce the reference fishing activity data. SACROIS consists of an operational application for reconciliation, verification and consistency checks of different unitary data streams. The SACROIS algorithm does not correct the data, its objective is to : - provide the best possible estimate of the various elements making up a tide from the available data sources - to identify the incompleteness of the various data sources and to propose a synthesis completed by indicators of data qualification resulting from the crossings. Twice a month, the SACROIS algorithm produces a new data source, a synthesis of all the available data sources: the reconstructed SACROIS tides. The SACROIS data have been calculated since 2000 for all fleets for which data are available: - North Sea - Channel - Atlantic (excluding tropical seiners), - Mediterranean (excluding bluefin seiners), - DOM (Reunion, Mayotte, French Guiana and the West Indies).

Les sous-unités statistiques de Guyane ont été définies par le SIH (Système d'Informations Halieutiques). Ces zones de pêche référencées permettent de collecter et de restituer la donnée halieutique des zones côtières de Guyane. Elles inventorient les zones côtières les plus fréquentées par la petite pêche côtière.

The "Fishing trips" data in the declarative flow correspond to the catch and fishing effort data declared by the professionals in the logbooks for vessels whose overall length is greater than or equal to 10 metres, and the fishing sheets for vessels whose overall length is less than 10 metres.

The objective of the PELGAS cruise is to monitor distribution and abundance of pelagic species fished in the Bay of Biscay, using two direct evaluation methods: acoustics and spawning estimates. The cruise was conducted in coordination with France, Spain and Portugal, in the framework of the European council regulations (EC No 1543/2000 of 29 June 2000 and No 1639/2001 of 25 July 2001).

Avant le 1er janvier 2016, la France comptait 27 régions : - 22 régions en France métropolitaine (en comptant la Corse). - 5 régions d'outre mer : la Guadeloupe, la Martinique, la Guyane, la Réunion et Mayotte (depuis 2011). Bien qu'obsolète, ce référentiel est conservé dans le Système d'Informations Halieutiques pour les données historiques.

To draw up an inventory of the "Western Channel" ecosystem by collecting complete data covering a maximum of compartments of this system (hydrology, planktonic compartments including fish eggs and larvae, benthic invertebrates, pelagic, demersal and benthic fish and cephalopods, birds and marine mammals). To determine the impact of climate change in the Channel on the composition of benthic invertebrate assemblages, the integrator group of these changes, through sampling of particular stations for which historical data exist. Carry out an intercalibration with the N/O Gwen Drez so that the CGFS (Channel Ground Fish Survey) data set can be continued on another vessel in the coming years.

ObsBio, the collection of individual biological parameters such as size, weight, sex, age are necessary data to know by elevation, the share of the populations in the recruitment of young fish, in the natural mortality and in the mortality by fishing

Ecological study of coastal nurseries in the Bay of Biscay: abundance and the quality of benthic and demersal fish juveniles (targeted species: common sole, Solea solea L.), biological indicators, relationship with the physical parameters of the habitats (bathymetry, sediments, hydrology) and with associated epibenthic populations (trawls for observing invertebrates).

Les unités statistiques de Guyane ont été définies par le SIH (Système d'Informations Halieutiques). Elles sont comprises dans les sous-secteurs côtiers (<12 milles) de Guyane. Ces zones de pêche référencées permettent de collecter et de restituer la donnée halieutique.
