@article{fdi:010053742, title = {{E}valuation of selectivity and bycatch mitigation measures using bioeconomic modelling. {T}he cases of {M}adagascar and {F}rench {G}uiana shrimp fisheries}, author = {{C}haboud, {C}hristian and {V}endeville, {P}hilippe}, editor = {}, language = {{ENG}}, abstract = {{T}ropical shrimp fisheries are characterized by various interactions with their natural environment and with other fisheries. {T}hese latter interactions can be explained by the high quantity of bycatch taken by industrial trawler fleets, which has a significant impact on fish populations associated with shrimps and thus also on finfish fisheries. {B}ycatch also includes emblematic species, which are subject to strict conservation measures decided by the international community. {I}t seems important to identify and assess the biological and economic consequences of different mitigation measures (increase of mesh size, turtle excluder devices and bycatch reducing devices). {T}his communication is based on case studies undertaken on the {I}ndian white prawn ({F}enneropenaeus indicus) and speckled shrimp ({M}etapenaeus monoceros) fisheries in {M}adagascar and on the brown shrimp ({F}arfantepenaeus subtilis) and pink spotted shrimp ({F}arfantepenaeus brasiliensis) fishery in {F}rench {G}uiana. {A} review of the impacts of these fisheries on resources and ecosystems is made and some results of experiments on mitigation devices given. {F}inally, the results of simulations obtained using a multi-species, multi-fleet, age-structured bioeconomic model, including modifications of catchability and costs related to the adoption of these devices, is presented and discussed.}, keywords = {{S}hrimp fisheries ; {S}electivity ; {B}ycatch ; {M}itigation ; {B}ioeconomics ; {M}odelling}, booktitle = {}, journal = {{A}quatic {L}iving {R}esources}, volume = {24}, numero = {2}, pages = {137--148}, ISSN = {0990-7440}, year = {2011}, DOI = {10.1051/alr/2011118}, URL = {https://www.documentation.ird.fr/hor/fdi:010053742}, }
