From May 2018 to April 2019, size distribution and composition of coral reef fish catches were monitored through a participatory landing survey in southwestern Madagascar. Fishers targeted a large diversity of fish taxa (75 families) and range of sizes (1.6-86 cm). Five predominant gears accounted for most of the catch (1360 [+/- 39] t), including mosquito net trawl (27.7%), beach seine (26.8%), speargun (7.2%), gillnet (30.6%), and handline (7.1%). Due to widespread use of gears made from mosquito nets, 75% of fishes smaller than 9 cm and 47% of juvenile fishes were represented in the total catch number. Large-size taxa (Scaridae, Lethrinidae, Siganidae, Acanthuridae, Synodontidae, Mullidae, and Labridae) were mostly harvested as juveniles. Catches varied by 8%-70% throughout the year. Size of coral reef fish, annual catches, and catch rates all declined since the 1990s. specialized bay of Toliara ImageJ management mosquito net trawl size distribution small-scale fisheries MADAGASCAR 040 [Early access] [13 p.] 2023 0969-997X https://www.documentation.ird.fr/hor/fdi:010088115 10.1111/fme.12637 0969-997X [F B010088115] https://www.documentation.ird.fr/hor/fdi:010088115 https://www.documentation.ird.fr/intranet/publi/2023-08/010088115.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2023-08-25 2023-08-25 fdi:010088115 fre
