Abstract

Suitable host fishes were identified for Unio terminalis delicatus (Unionidae) from Gölbaşı lake. It was observed the
glochidial infestation for the suitable host fishes in the laboratory
conditional. In this study, five different fish specieses (Anguilla anguilla, Clarius gariepinus, Barbus luteus, Orechromis
niloticus, Cyprinus carpio) were
used as host fish in order to U. terminalis
delicatus. It was placed in each aquarium eighteen fish and
three mussels. Fishes, which are used as host were held in five aquariums of
140 liters capacity with no substrate. All the aquarium were sampled every
other day for up to 45 days. The presence of glochidia in the gills and fins of
the fish was studied in a stereomicroscope. The following stage,
mussel-fish-host relationships were established. In the aquarium in which C. carpio was placed, the conglutinates
were found to differ both in quantity and in structural form. Although the
larvae of U. terminalis delicatus released successfully on three fishes species: B. luteus, C. carpio and O. niloticus,
they weren't prefer to A. Anguilla and
C. gariepinus as host fish. These
observations show that of three prefable host, C. carpio is the best option to for host fish selectivity U. terminalis delicatus
