Abstract:

The dataset includes a sample of fishery data on reef fish catches (catch per fishing trip, fish length, and catch composition at family level), minimal length at maturity for reef fishes, and fisher census in the Bay of Toliara, southwest Madagascar. These data were collected as part of a participatory survey from May 2018 to April 2019 at 8 villages in the Bay of Toliara.<br><br> Specifically, 4 data files are provided:<br> (1) suivi_part_toliara.xlsx ; <br>(2) dt_station.csv ; <br>(3) Juvenile_size_family2.csv; <br>(4) pecheur_baie_toliara.xlsx<br> Each data file is described in the attached documentation This dataset also include the R code that was used for processing this data.
