4.1.3.2.Time-series of landings and discardsData from the French fleetTimes-series of landings from the French fleet area available and will be update in due course during the project. Currently French landings and effort data prior to 1999 are not available in the same database as data from 1999. The loading of archive data in the current database is under way. Deep-water species ladings and effort will be updated as and when all database revison is finalised. In tables below, times series of, fleets size (number of vessels), fleet power, fishing time, fishing effort and landings are given for vessels having landed more than a certain amount of deep-water species. These estimates are available in DEEPFISHMAN data for blue ling, roundnose grenadier, black scabbardfish, deep-water sharks and all deep-water species. For every species or group, fleet number, effort and total landings of vessels having landed more than threshold levels (5, 50 100 and 500 tonnes of the species or group of species) were calculated. The 5 tonnes threshold allows excluding vessels with small deep-water fishing activity and assessing the size of the fleet for which this activity is significant. Higher threshold allow to assess the size of the fleet and the effort directed to deep-water species.The list of species considered as deep-water for this analysis includess: blue ling, roundnose grenadier, black scabbardfish, orange roughy, greater forkbeard, alfonsinos, roughhead Grenadier, common mora, deepsea cardinalfish, deepsea scorpionfish, deep-water sharks and chimaeras. Table. 4.1.3.2a. French fleet of fresh fish trawlers, vessels having landed more than 5 tonnes of blue ling per year, number of vessels, total power (kw), number of days at sea and days fishing, fishing effort (fishing days* 1000 kw), landings of blue ling, landings of deep-water species (including blue ling) and all species (including deep-water).

French fleet of fresh fish trawlers, vessels having landed more than 500 tonnes of blue ling per year, number of vessels, total power (kw), number of days at sea and days fishing, fishing effort (fishing days* 1000 kw), landings of blue ling, landings of deep-water species (including blue ling) and all species (including deep-water).
