The Influence of Marina Characteristics on Non-native Colonisation

The marina properties, such as; salinity range, tidal fluctuations, depth, and ascidian presence in-fluence the distribution of invasive non-natives. Transport vectors, aquaculture fishery practic-es also have an important role in non-native species during bioinva-sion process. We focused on 10 marine invertebrates UK. This study explained ecology five (Styela clava (As-cidia), Didemnum vexillum (Ascidia), Caprella mutica (Crustacea), Crepidula fornicata (Gastropo-da), Watersipora subtorquata (Bryozoa)) characteristics colonization (Austrominius modestus (Arthropoda), Ciona intestinalis Botrylloides violaceus Tricellaria inopinata (Bryozoa), Bugula neritina Wales coasts. site deployed settlement tiles inner outer tile as two positions each marina: An equal number vertical horizontal was at with half-sampled weeks (very early colonization) eight (later colonization). results showed that some variations affected species.
