Description
The MEDITS survey (International bottom trawl survey in the Mediterranean is organized to monitor the demersal resources in the Mediterranean. It intends to produce relevant information to support the fishery policy by collecting abundance data and biological parameters of fish, crustaceans and cephalopods species. The hauls are positioned following a depth stratified sampling scheme with random drawing of the positions within each stratum. The hauls are made in the same position from year to year. The following depths are fixed in all areas as strata limits : 10 - 50 m, 50 - 100 m, 100 - 200 m, 200 - 500 m, 500 - 800 m. The protocols, including the specifications of the standard gear are described in an instruction manual. The series began in 1994 with one yearly survey. Ten Mediterranean countries are applying the Medits protocols (about 1100 hauls per year).
