AB  - Madagascar benefits, in some coastal regions, from conditions particularly favorable to penaeid shrimps. The global objective of research is to evaluate the production of catches of industrial shrimps during the first four months in the B zone and the C1 zone of the 2021 campaign. Additionally, the specific objectives of this survey are to: highlight the evolution of the catches; of the Catch per Unit Effort (CPUE) and industrial fishing effort; and also to highlight the specific composition of the catches and the abundance of every species caught. For the methodology, observations on land and on board boats, were made in the B fishing zone and the C1 zone. Because of this, five species of penaeids were targeted: Metapenaeuses monoceros, Fenneropenaeus indicus, Penaeus semisulcatus, Penaeus monodon and Marsupenaeus japonicus and the other mixed shrimps. The monthly production between April and July 2021 in the two studied zones varied from 17529 to 32788 kg in the B zone and from 12402 to 24819 kg in the C1 zone. While the variation ofin average Catch per Unit Effort (CPUE) was respectively from 397.74 to 2127.21 kg/h in the B zone and 520.84 to 2459.73 kg/h in the C1 zone. The abundance of species catches varied from 43% in the B zone to 45% in the C1 zone, concerning Metapenaeus monoceros and 3% in the B zone and 2% in the C1 zone, concerning Penaeus monodon. Nevertheless, the present document is going to give more indication on the state of the catch yield in relation to the pressure exercised in fishing zones over several decades.
