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.

As part of the implementation of the monitoring programme of the Marine Strategy Framework Directive (MSFD), the monitoring of demersal fish and cephalopods in coastal soft environments was deemed a priority. Annual observation campaigns of coastal nurseries on soft bottoms were carried out by the Laboratoire Halieutique Méditerranée of the Ifremer station in Sète. The objectives of these campaigns are 1. To evaluate the density, biomass and distribution of fish and cephalopods by trawling, in particular benthic and demersal juveniles (red mullet, gurnard). To do this, around one hundred standardised trawl surveys were carried out over the entire coastal strip of the Gulf of Lion situated between 5m and 40m depth. 2. To systematically measure the size of the individuals collected in order to characterise the importance of the nursery function in the areas observed and to better understand the population dynamics of local species. 3. To gain a better understanding of the coastal zone ecosystem by systematically identifying all the species encountered (including benthic and pelagic invertebrates other than fish and cephalopods), the macro-waste observed and by characterising their hydrological habitats (CTD, oxygen, fluorescence, pH, turbidity, etc.).

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.

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 annual PELMED (PELagiques MEDiterranée) fisheries resource assessment campaign is carried out by the Laboratoire Halieutique Méditerranée of the Ifremer station in Sète. The objectives of these cruises are : 1. Evaluate the biomass of small pelagic fish (anchovies, sardines) by direct method. For this, the campaign must alternate between acoustic prospecting and identification trawling. An acoustic signal is sent from a sounder fixed under the vessel and each time it encounters the bottom or schools of fish, it is reflected and retransmitted to the sounder. In this way, the shape and intensity of these echoes that materialize the schools of fish can be observed continuously. Species identification trawls are carried out in order to define the proportion of species present in the echoes detected. 2. Collecting as many biological parameters as possible on the target species of small pelagics (anchovies, sardines, sprats) to better understand the population dynamics of these species. For this purpose, morphometric measurements, as well as the determination of the sex and maturity stage of the fish are carried out. Finally, otoliths are taken in order to determine the age of the fish. These biological parameters are very important to complete the biomass assessment and have a better understanding of the processes underlying the variability of these populations. This allows for example to determine the age structure or size structure of the populations, to have an idea of their energy reserves, etc. 3. To better understand the pelagic ecosystem as a whole, from plankton to top predators. The primary goal of the PELMED cruise is to evaluate small pelagic stocks, but it also aims to accumulate as much data as possible on the different compartments of the pelagic ecosystem, from physical parameters (temperature, salinity) to top predators (marine mammals, birds), through the different lower trophic levels (phyto- and zooplankton, small pelagic fish). Thus, after each trawling, a hydrological station is carried out with the measurement of temperature and salinity along the water column via a CTD, water and phytoplankton samples with a Niskin bottle and zooplankton samples using a vertical line of WP2. Finally, throughout the campaign we carry out the observation and counting of birds and marine mammals. In addition to the understanding of the ecosystem, this should provide a number of indicators necessary for monitoring the marine environment under the MSFD (Marine Framework Directive).

The Bargip project : acquisition of scientific data and knowledge to produce advices on integrated management of European sea bass (Dicentrarchus labrax) in North-East Atlantic.

Since 2001, an annual stock assessment of Manila (Ruditapes philippinarum) and European (Ruditapes decussatus) clams has been carried out in March in the Gulf of Morbihan and the Noyalo River. The objectives of this survey are : 1) estimate by direct assessment, the biomass of the stock and its geographical distribution; 2) estimate the exploitable biomass and exploitation potential for the sampled sites in particular, in areas reserved for professional fishing; 3) to establish a diagnosis, with a medium-term vision, on the state of the stock; 4) to propose the implementation of appropriate management measures. Two cruises were also carried out in 1996 and 1997.

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.

A metier in the Fisheries Information System is a fishing practice defined by a fishing gear and a target species. They are used for statistical purposes to evaluate fishing strategies and efforts.

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).
