What is it about?
This chapter provides detailed information and photographs of 84 fish species from 11 diverse families, some of which are commercially and ecologically significant. The fishes were sampled along the Negro and Tapajós rivers. These communities are both inside and outside protected areas, as shown in the accompanying maps. The chapter presents data on distribution, abundance, fish sizes, length-weight relationships, and fisheries, including fish biomass caught by fishing communities. It also highlights fishing gear use, seasonality, and sizes of fish caught for commercial and food purposes. Some fish species were grouped due to difficulties in distinguishing them during sampling. The Characidae, Serrasalmidae, and Hemiodontidae families were found to be particularly diverse, with species playing vital roles in ecological processes and human use. The family Prochilodontidae includes two of the most important fish species providing food to local communities in both rivers.

Why is it important?
The study provides detailed information on 84 species of fish belonging to 11 different families, which enriches scientific knowledge about the diversity of aquatic fauna in the Negro and Tapajós river basins. By identifying and describing the species present in the study area, you can improve the understanding of aquatic biodiversity and help design more effective conservation strategies to protect these ecosystems and their vulnerable species.
Perspectives
It is expected that the study will provide new information about the fish species present in the region, enriching the scientific knowledge about the biological and ecological diversity in these river basins. It will also allow for the identification of fish species relevant for commercial fishing and the functioning of local aquatic ecosystems. With the data collected on species distribution and abundance, more effective strategies can be designed for the conservation of aquatic biodiversity in the region, particularly for threatened or vulnerable species. Understanding the role of each species in aquatic ecosystems and their economic importance will enable better assessment of their relevance and informed decisions for their conservation.
