Initially, it involved only four Countries: France, Greece, Italy, and Spain. Over time, the survey expanded to include other European countries and geographical sub-areas. Today the MEDITS survey covers 18 GFCM geographical sub-areas (GSAs) over an area of 543,000 km\u00b2, with an average of 1,283 sampling stations annually. Collaboration with non-EU countries has been facilitated by the FAO regional projects and the General Fisheries Commission for the Mediterranean (GFCM).<\/p><p>The main characteristics of the survey are:<\/p><ul><li>A standard design of sampling bottom trawl gear (GOC 73) is used (codend mesh size of 20 mm stretched mesh).<\/li><li>The survey uses a depth-stratified random sampling scheme, with strata defined by depth and geographical zone.<\/li><li>Hauls are distributed proportionally to the surface area of depth strata, which limits are: 10-50m, 51-100m, 101-200m, 201-500m, and 501-800m.<\/li><li>Haul duration is determined by depth: 30 minutes on the continental shelf (10-200m) and 60 minutes on the slope (201-800m).<\/li><li>The surveys are scheduled between late spring and summer (May to July) and conducted during daytime.<\/li><li>All species larger than 1 cm are identified, with total weight and number of individuals recorded. Sex and gonad maturation stage are identified on a set of target species.<\/li><li>A length-stratified random sampling is applied to collect biological data, such as otoliths of bony fish and individual weight.<\/li><li>The MEDITS protocol also defines common formats for data exchange, including 5 different standards:<\/li><li>TA: hauls details and specifications;<\/li><li>TB: aggregated data on species&#8217; total number and weight;<\/li><li>TC: length frequency distributions by length, sex, and maturity stage;<\/li><li>TE: individual data of length, weight, age and sex;<\/li><li>TL: marine macro-litter data<\/li><\/ul><p>For further details refer to MEDIT Handbook (Anonymous, 2017), to Spedicato et al.
