RECLIO survey catch data: Bentho-demersal assemblages of the Gulf of Lion (North-western Mediterranean) from 1988 to 1989
Three Reclio surveys took place between june 1988 and february 1989, two surveys in 1988 and one in 1989. The objective of all this serie of survey was to study the seasonal macrodistribution and the importance of age groups 0 and 1 of the main commercial species fished by bottom trawl in the Gulf of Lion. About sixty trawl hauls were carried out during each survey, with 30 minutes mean duration of each haul. An inventory of the main bentho-demersal commercial species was carried out, their number and total weights were measured. During the first survey in 1988, size measurements of the main commercial species were also carried out. Finally, some illicium samples were taken from the anglers for age determination purposes.

Devices
The sampling plan used was a random plan stratified according to depth and geographical area. The gear used was a bottom trawl (the Drezen 20PM), having a vertical opening of less than 1.8m. The trawl hauls lasted approximately 30 minutes for a depth between 10-150m and 60 minutes for a depth of 150-500m. They systematically target bentho-demersal species in Gulf of Lion.
