| "Small trades" refers to the body of fishing boats, excepting the trawlers, which have a trawling license and the tuna/sardine boats, which have a pelagic fishing license. The ships that fish for small pelagic fish by using a lamp are only included for the other trades they ply, if applicable. Whereas certain "small trades" work offshore, the majority of them exploit the lagoons and coastal area. The importance of the coastal areas in general, where a large number of biological and ecological processes are being developed, need no longer be demonstrated: A large part of primary and secondary production takes place in these areas, which host moreover many reproduction and nursery sites for a great many species. "Small trade" fishing is one of the main... |

| Lagoons are highly productive areas representing more than 50% of the coastline area in Languedoc-Roussillon (South of France, Mediterranean sea). These lagoons are very different in their environmental conditions, human influences, eutrophication levels and aquaculture intensity. Based on macrophyte communities associated with soft substrates, two indices of taxonomic diversity (the "average taxonomic distinctness" (Delta(+)) and the "variation in taxonomic distinctness" (Lambda(+))) were used to discriminate four of these lagoons (Thau, Salse-Leucate, Bages-Sigean and Mauguio). Bages-Sigean presented a significant higher average taxonomic distinctness (p < 0.05) and Salse-Leucate had a significant higher variation in taxonomic distinctness (p <... |
