Distribution and population structure of the Unionidae family in the Kupa River in Karlovac County.

Abstract

Distribution and population structure of Bivalvia from the Unionidae family in the Kupa River course in Karlovac County was analysed from April to October 2018. At nine different locations, six species from four genera of this family were found. The dominant species is Unio crassus which takes up 32.5%, while the least represented one is Pseudanodonta complanata with 4.0%. During this research, the invasive species Sinanodonta woodiana was found in four locations. The objective of this paper is to determine the number of species from the Unionidae family and the incidence of every species within the population, and their distribution in the Kupa river in Karlovac County. This is the first research aimed at the distribution and population structure of the Unionidae family in the river Kupa in Karlovac County.
