Measurements of the number of larvae oyster and the water temperature in the Spuikom Ostend in 1964. Surface water samples (100L) were taken regularly and plankton samples were taken using a planktonnet to calculate the number of Ostrea larves. The measurements within this dataset were digitized by VLIZ from the publication: Polk, P. (1965). Observations sur l'éclosion de larves d'huîtres dans le bassin de chasse d'Ostende Council Meeting - International Council for the Exploration of the Sea, CM 1965(15) ICES: Copenhagen. 4 pp

Biomass of plankton groups and presence records of the most important species related to the oyster farming which were present in the Sluice Dock between 1960 and 1964. The data were digitized by VLIZ from the original reports: Leloup, E. et al. Recherches sur l'ostréiculture dans le bassin de chasse d'Ostende. Ministère de l'Agriculture. Commission TWOZ. Groupe de Travail Ostréiculture: Ostende.

This dataset is based on the Atlas of Freshwater Bivalves in Mainland Portugal published by ICNF in 2006. It presents occurrence data of native and exotic freshwater bivalves on water bodies in hundreds of sampling stations at Mainland Portugal, from 2001 to 2004. There are records of 12 native species and one exotic with confirmed occurrence in Portugal, namely Corbicula fluminea (O. F. Müller, 1774). The project "Atlas of freshwater bivalves in mainland Portugal" was coordinated by Joaquim Reis and involved the participation of several individual and institutional collaborators.
