- Opis:
- A new locality of the Chinese clam Sinanodonta woodiana (Lea, 1834) was found in a temporarily drained Czes³awicki Pond (10.8 ha) near the village of Janis³awice (Dolina Baryczy Landscape Park, Sooenie community, Ostrów Wielkopolski district, Wielkopolska region) in September 2006. In this fishpond a dense population of the Chinese clam was observed whose number was estimated as about few hundred individuals. During the second control (January 2007), we observed a few hundred clams in the same pond and we found smaller populations in adjacent ponds of the same Janis³awice complex. During a detailed control of the ponds (drained in the autumn 2006) of the fishpond complex near Konradów (120 ha, 2 km SW of the Janis³awice complex), only one damaged, empty shell of the Chinese clam was found. Specimens with maximum shell dimensions – 185 mm length and 140 mm width – were found in the Czes³awicki Pond. Before, S. woodiana was found in Poland only in heated waters which were thought to be necessary for the development of this species. This is the first Polish record of the species in a reservoir with a natural thermal regime.
