The French sardine fishery ArchiMer
Duhamel, Erwan.
This approach of the French sardine fishery shows mainly that pelagic trawlers are targeting less and less sardine, year after year. In an assessment approach, it would be necessary to define an estimation of fishing effort, but it will be very difficult. We are able to compt the number of fishing days, but not the time of fishing (or number of shoots for example for purse seiners) or time of searching schools. So, accessibility and catchability could be certainly more accurate than the fishing effort for assesment purposes.

The French anchovy fishery ArchiMer
Duhamel, Erwan; Biseau, Alain; Masse, Jacques; Villalobos, Hector.
The french fishery of anchovy is divided in two groups defined by gears : purse seine and pelagic trawl. The average length of these vessels is about 20m. This fleet is very opportunistic : all trawlers are using several trawls during the year, to catch sometimes bass, tuna, hake, or scampi, and purse seine are mainly fishing sardine. Each year, the main anchovy catches are provided by pair trawlers. Purse seiners operate often in coastal areas (<10 nautical miles); trawlers may operate until 50 nautical miles offshore but are banned inside the three miles coastal zone. The pair trawlers may operate from Basque country to western Channel according to fish availability. Purse seiners usually stay around their home harbour.
