Catch data from a 1949 trawl survey in Tunisia (South-West Mediterranean)

this dataset contains an inventory of the benthic fauna of the tunisian coasts caught by bottom trawling and dredging. the objectives are not known. we assume that this is an exploratory seabed trawling survey to assess faunistic composition and the fishing possibilities in the region with this gear. we know that the inventory was probably carried out by jean-marie pérès (who was at the time assistant professor at the science faculty in marseille) and for which a hand-written copy by jacques ancellin (director of the boulogne-sur-mer laboratory after the second world war and he joined the ostpm in 1942) was recovered. only species presence were recorded.

本数据集收录了突尼斯海岸底栖生物群落的清单，这些生物通过底部拖网和挖泥作业被捕获。其具体目标尚不明确。我们推测，这应是一次探索性的海底拖网调查，旨在评估该区域使用此类渔具的生物群落构成及捕捞潜力。据知，该清单可能由让-玛丽·佩雷斯（当时为马赛科学学院助理教授）编制，而手写副本则由雅克·安塞尔林（第二次世界大战后成为布洛涅-比扬库尔实验室主任，并于1942年加入国际海洋生物保护组织）所保存。记录仅限于物种的存在情况。
