Didemin ascidians: rapid colonizers of artificial refs in eilat (red sea)

摘要

Ascidians frequently occur on man-made surfaces submerged in marine waters and constitute a major technical and economic problem worldwide. In Eilat (Red Sea), arti- ficial reefs constructed for attractive diving are frequently fouled by ascidians. In this study we examined aspects of temporal and spatial fouling of two common ascidians, Diemnum granulatum and Didemnum sp., on two modular experimental artificial reefs.
