Levantamento da diversidade de peixes do município de Itaituba-Pará depositados na coleção ictiológica do museu de zoologia da UFRA

Abstract

Biodiversity is used to describe the diversity of life on Earth, from the level of microorganisms to the ecosystem of a region. The relationship between this biodiversity and the hydrological system is fundamental to maintaining the health of aquatic ecosystems. Fish are considered indicators of ecosystem condition or even to assess a specific impact on species. Aiming to understand the ichthyofauna in the Southwest Pará Mesoregion, this work aimed to characterize the ichthyological collection with a checklist of species, highlighting the status of threats and their economic importance in the distribution of rivers in the municipality of Itaituba-Pará. The ichthyological material from the Museum of Zoology of the Federal Rural University of the Amazon (MZUFRA) was reviewed and updated in Microsoft Excel 2020. For this purpose, tools such as the International Union for Conservation of Nature's (IUCN) red list and publications of the Ministry of the Environment (MMA) were used in this assessment to characterize the status of threats together with the Global Biodiversity Information Facility (GBIF) platform to verify whether species are endemic or not. This study was developed by thirteen collection points throughout along the distribution of rivers in the municipality of Itaituba. Through the characterization of species and other analyses, all collection points were analyzed through the quantities of each species in the location. The methods used in this study proved efficient, in most cases, to determine river locations with the highest and lowest quantity of species using the frequency of the species. The classification of species and feeding habits in the environment were also observed. The ichthyological collection is composed of 2,048 species. Through this survey, we obtained promising results on the representation of the species found in the collection and in the region.
