Fauna acompanhante na pesca industrial de camarão no Oceano Índico: composição específica, variação sazonal, uso e mitigação da captura

Abstract

The aim of this study was to find out about the specific composition of the accompanying fauna and its seasonal variation in the industrial shrimp fishery in the Indian Ocean, as well as the destination or utilisation of this accompanying fauna, the type and efficiency of the devices used to reduce the capture of accompanying fauna in this fishery. This research was carried out on the basis of a bibliographical review using scientific articles, undergraduate theses, dissertations and scientific reports. The PRISMA guidelines for conducting a systematic literature review were applied. In this process, 207 studies from the period 1994 to 2022 were identified, of which 42 were used to compile the results. 42 were used to compile the results. In terms of the specific composition of the accompanying fauna, 55 families of fauna were listed, with 47 families of fish caught of which 12 were pelagic, 4 families of molluscs, 2 families of crustaceans, 1 family of reptiles totalling 212 species. Among the fish, 92 species of demersal fish belonging to 35 demersal families and 98 species of pelagic fish belonging to 27 families were recorded. For Kuwait, South Africa, India and Madagascar it was found that in terms of seasonality some species are caught in a single season, but most species are caught or occur in all seasons, which means that there is little seasonality. Around 57.7% of the accompanying fauna is used for the production of fishmeal, poultry and manure, 33% for the production of fish paste and 9.3% is marketed to coastal communities. Fauna reduction devices have a significant efficiency of between 6.1- 62.7% in reducing accompanying fauna. The devices used to reduce accompanying fauna (TRADUÇAO NOSSA)
