Abstract

Unio crassus is endangered European freshwater mussel. Their body is protected by a shell, they feed by filtration and live in clean streams and rivers with finer sediment. They are separate sexes and fertilization occurs in the body of the female. Within the breeding season the females show a unique way of spreading larvae. There are two stages between an egg and young individual: parasitic larval stage and juvenile detritovores. The number of species is highly dependent on the rate of efficiency in finding suitable host in larval stage and the chemical conditions in the substrate on which the juvenile stage is extremely sensitive. Because of increasing population and industrial activities, many of its habitats are destroyed and can therefore carry out various projects of restoration of habitats, species reintroduction and monitoring as well as the education of the local population.
