| 'In the Southern Caspian Sea, mass development of Amphibalanus eburneus led to a considerable decrease in the biomass of native species of molluscs and hydroids. Under the conditions of food shortage, it prevents the development of other organisms in the fouling. This competition is particularly severe in the larval stage. The larvae of Amphibalanus sometimes reached up to 90% of all plankton in some areas of the Caspian Sea.' (Zaitsev and Ozturk 2001). | ||
