Abstract. Abstract: Studies on ichthyoplankton ecology become essential when one realizes the importance and influence of this component in dynamics, conservation, and maintenance of fishery resources. However, ecological information about this subject is still scarce and has not been properly valued and used by environmental managers and decision-makers. In this study, we present the state of the art of research on ichthyoplankton in the Amazon region. The number of studies has been increasing over time but they are scarce and restricted. We hope this study may encourage research related to ichthyoplankton in the Amazon region.
