RESUMO:

The synthesis of scientific knowledge provides an important guide to identify gaps and trends of studies. Here, we conducted a scientometric review of the freshwater ichthyoplankton literature to investigate: (i) temporal trend in publications; (ii) the scopes and habitats; (iii) the spatial distribution; (iv) the studied species and their respective conservation status and (v) the drivers of the spatial distribution pattern of studies. We found 652 studies published between 1959 and 2020. Most studies sought to understand the determinants of the basic biology of ichthyoplankton and were carried out mainly in rivers and lakes. Regarding the spatial distribution, we found studies in only 22,3% of the known freshwater ecoregions. Only 870 species have information about ichthyoplankton, it is only 4.80% of the known freshwater fish species. The ichthyoplankton species found in the studies are assessed by the IUCN in six threat status, and for many species (303) there are no assessments. The area of the ecoregions, the density of highways, the volume of rivers and the number of hydroelectric plants were the determining factors for the spatial distribution of the studies. Thus, the biases found in relation to the types of habitats, the spatial distribution and the few fish species studied in the ichthyoplankton phases demonstrate the need for further studies seeking to resolve these gaps. Finally, we emphasize that the lack biological basic information is a serious problem to implement actions that safeguard fish biodiversity in freshwater ecosystems.
