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.

1988年6月至1989年2月期间，共进行了三次Reclio调查，其中1988年进行两次，1989年进行一次。本次调查系列的目标在于研究狮子湾底层拖网捕捞的主要商业物种的季节性宏观分布，以及0岁和1岁年龄组的重要性。在每次调查中，共进行了约六十次拖网作业，每次拖网的平均持续时间为30分钟。对主要底栖-近底商业物种进行了清单编制，并对其数量和总重量进行了测量。在1988年的首次调查中，还对主要商业物种的尺寸进行了测量。最后，从渔民处采集了一些鳗鱼样本，以用于年龄鉴定。
