  abstract = {{T}he use of mosquito nets, primarily for targeting small and/or juvenile fish, has rapidly increased in {W}estern {I}ndian {O}cean shallow seagrass beds and coral reefs over the last 20 years. {H}owever, to date, invertebrate by-catch by locally-made fishing gear has not been reported. {W}e studied the mosquito net trawl fishery in seagrass areas in the {B}ay of {T}oliara, {S}outhwest {M}adagascar through the {GPS} tracking of fishers from {A}ugust 2018 to {F}ebruary 2019. {C}atches were monitored through monthly landing surveys to characterize spatial temporal patterns in the abundance and diversity of macroinvertebrates in the seagrass beds. {F}ishing was carried out at low tide, mostly at night, by fishers pulling a hand-made trawl net of varying dimensions. {O}verall, 43 macroinvertebrate taxa were identified out of 217,080 individuals collected from 109 catch samples. {C}atches were generally composed of crustaceans (mainly {P}ortunidae, {P}rocessidae, {P}enaeidae, and {A}lpheidae). {T}he crab {T}halamita mitsiensis largely dominated the abundance and biomass of the macroinvertebrate assemblage (from 6% to 100% and from 5 to 100% of the overall density and biomass, respectively). {M}acroinvertebrates composed 1.5% to 100% of the total catch per trip (i.e., 4-55 kg trip(-1)). {T}hey were sold for human consumption or animal feed, which provided additional income to fishers ({USD} 1-24 trip(-1) and 1-72% of catch income per trip). {T}his study revealed that macroinvertebrate resources provide valuable by-catch to small-scale fishers in {S}outhwest {M}adagascar. {T}his bycatch generates income that further encourages the use of mosquito net trawls and exacerbates their negative effects on coastal seagrass ecosystems and fisheries.},
