Despite the ecological importance a

Despite the ecological importance and globally threatened status of freshwater bivalves, the freshwater mussel fauna of Turkey
has hitherto received little attention. The aim of this study was to describe the ecology of freshwater mussels of the Lake Sapanca
basin (northwest Turkey) to provide baseline data against which to measure future trends. Five native mussel species belonging to 3
genera were encountered in surveys: Anodonta cygnea, A. anatina, Unio pictorum, U. crassus, and Dreissena polymorpha. In addition, an
invasive species from Asia, A. woodiana, was recorded in the region for the first time. A. cygnea and U. pictorum were the most abundant
species in the lake, while U. crassus was most abundant in the associated stream. Age and growth parameters were estimated for U.
pictorum and U. crassus, and indicated that the latter species had a younger median age and faster growth rate than the former, possibly a
function of exclusively occupying a nutrient-enriched stream. The bioecological features of the bivalve fauna of the Lake Sapanca basin,
as well as the implications of the introduction of A. woodiana, are discussed.

Ten spyte van die belangrikheid en Ekologiese Status van bedreigde varswater tweekleppiges Wêreldwyd die varswater mossel fauna Turkye
het tot nou toe min aandag. Die doel van hierdie studie was om die ekologie van varswatermossels van die Sapanca Lake beskryf
wasbak (Noordwes Turkye) om basislyn waarteen toekomstige tendense Data meet voorsien. Vyf Native mossel spesies wat tot 3
genera ondervind in Opnames: Anodonta Cygnea, A. Anatina, Unio Pictorum, JOU Crassus, en Dreissena polymorpha. Daarbenewens is 'n
indringerspesies uit Asië, A. Woodiana, is aangeteken in die streek vir die eerste keer. A. Cygnea en U. Pictorum was die volopste
spesie in die Lake, terwyl U. Crassus was volopste in die verband te stroom. Ouderdom en groei Parameters is beraam vir U.
en U. Crassus Pictorum en aangedui dat die laasgenoemde spesie het 'n jonger ouderdom en Mediaan vinniger groeitempo as die eerste, moontlik 'n
funksie van uitsluitlik besetting van 'n voedingstof verryk stroom. Bioecological die kenmerke van die tweekleppige fauna van die Sapanca Lake wasbak,
asook die implikasies van die bekendstelling van A. Woodiana, word bespreek.
