Review of the lampreys (Petromyzontidae) in Bosnia and Herzegovina: a current status and geographic distribution

Abstract

The general status of lampreys (family Petromyzontidae) in Bosnia and Herzegovina was reviewed to determine the species composition and geographical distribution of this group in the region. This paper reviews the available literature to provide a critical analysis of the current status of lamprey species. According to the available data, their status can be considered as indeterminate, largely due to limited published records. While eight species are recorded as present in the region (Eudontomyzon danfordi, E. mariae, E. vladykovi, Lampetra fluviatilis, L. planeri, L. soljani, Lethenteron zanandreai, Petromyzon marinus), only three species (E. vladykovi, L. soljani, P. marinus) are confirmed to occur. Their distribution is recorded in waters of both the Danube and the Adriatic Sea catchments. Given the deficiencies in our understanding of the taxonomic status of some populations and knowledge of the geographical distribution of lampreys inhabiting both catchments, research focused on improving understanding of the phylogenetic, morphological and phenotypic traits of lampreys in Bosnia and Herzegovina is warranted to resolve these uncertainties. Problems related to threats and conservation, and future perspectives for protective management strategies are discussed. This paper provides the context for future biodiversity conservation and management with regard to lamprey species in Bosnia and Herzegovina.
