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 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.).

The MFSP repository of the Fisheries Information System corresponds to the combination of Parameters, Supports, Fractions, Methods and Units. It allows variables to be entered, banked and retrieved. It is associated with many other repositories: species, gear, etc.

For some commercial species, coefficients called live weight equivalents allow the live weight of the fish to be calculated from the weight recorded on landing, or from the net weight of the various processed products prepared on board or in factories located on the coast.

Size-weight relationships are specific to each scientific species and its environment. They allow the size of an individual to be determined from its weight or vice versa. These relationships are established statistically from a sample of individuals representative of the species.

The gear repository of the Fisheries Information System includes, on the one hand, the FAO fishing gears enriched with national specificities and, on the other hand, the sampling gears used during the fisheries surveys conducted by Ifremer and its partners.

The repository of location in the Fisheries Information System is divided into 3 categories: places on land, areas at sea and regulatory areas at sea. Each of these is organised hierarchically. There are 93 levels of places in Harmonie: a metadata sheet exists for each of them with, when it exists, a geographical layer.

The consolidated database shows the spatial distribution of sampling effort by French and Monaco oceanographic campaigns. The measures are divided between the mouth of the Rhone, the Gulf of Lions, and Ligurian and Provence seas. The database contains 55 campaigns or time series, over 5 decades from 1962 to 2010. 28 are oceanographic campaigns of spatial strategy (some were revisited), 14 of temporal strategy, 2 of spatio-temporal strategy, and 1 one-time campaign. In total, it has 24,886 entries including: 19,027 nitrate data - 13,826 nitrite data - 11,452 ammonium data – 20,936 phosphates data – 14,605 silicates data. The majority (92%) of associated temperature and salinity data is available.
