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

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.

Species distribution is provided as a layer of points representing in situ observations of organisms during submersible dives into the canyons of the Mediterranean mainland.

The repository of commercially exploited species of interest in the Fisheries Information System is based on the FAO's ASFIS repository enriched with species of high commercial interest in France (metropolitan and overseas).

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 observation of ecosystems by Ifremer's Fisheries Information System (SIH) is based on a network of sea cruises. It aims to assess the state of stocks of the various species fished in France and Europe. It also enables the characterisation of the marine ecosystem in which the populations evolve. 23 scientific cruises take place each year at sea, enabling data to be collected for more than 30 years for the oldest. Thanks to the use of standardised fishing gear, the data acquired each year on board scientific vessels or professional fishing vessels contribute to the calculation of the index of abundance, with thousands of fish taken during timed trawls. The fish are measured and their age is assessed by measuring their otoliths (small bones located in the inner ear of the fish).

The scientific species repository of the Fisheries Information System lists the species observed during fishing campaigns or within the framework of the observations of collection programmes (ObsVentes, ObsMer, Campaigns, etc.).
