IMIS - Marine Research Groups

This dataset contains the supply of larvae to the bay of Villefranche-sur-Mer (43.69°N, 7.315°E) by capturing settling larvae using CARE light-traps. Traps are set in the evening and collected the next morning, usually every week (with some variations: more intense effort during some periods and some missing dates due to weather constraints). Here we report: -the date of collection of the traps (`date`) - the identification of organisms (`family`, `genus`, `species`; when individuals can only be identified to family or genus, the subsequent fields are left blank) -the number of individuals caught (`n`) - the number of traps set (`sampling_effort`) -the Catch Per Unit Effort (`cpue`=`n`/`sampling_effort`) - the location of sampling (`lat` and `lon` of the bay of Villefranche-sur-Mer). All coastal fish species caught are reported so if a species is not reported on a given date, it can be considered absent (even though it is not explicitly set to 0 in the file).
