Description

Counts of fixed Ostrea edulis and Crepidula fornicata species on 4 zones of a tile from an oyster collector in relationship to light intensity. The data were digitized by VLIZ from the original report: Bracke, E.; Polk, P. (1969). Contribution à la connaissance de la faune marine de la côte belge: 6. L'influence de la lumière sur la fixation d'Ostrea edulis (L) et de Crepidula fornicata (L) sur les collecteurs d'huîtres.

Additional info

The difference of phototropism and phototaxis of both molluscs influenced their fixation. The orientation of both molluscs is towards the incoming light-direction, less pronounced when the light-density to the center of the tile is decreasing. The density of the populations of oysters is increasing towards the center of the tiles by decreasing light-intensity, the density of the Crepidula-population decreasing towards the center of the collector.
