Abstract:

The conditions assessment of hydrobiont`s settlements in a various water area is of great theoretical and practical importance. This issue is particularly relevant for organisms that create abundant settlements on the artificial substrates in a coastal water areas. The evaluation of the modern (2015) condition of mytilidae fouling of some hydraulic structures of various coastal waters of Sevastopol was made. Based on these data, the calculation of the biofilters capacity formed by mussels and mytilasters in the surface horizon of hydraulic structures was made. It was assigned that on the underwater part of the embankment of the Sevastopol Bay, a biofilter 3 times exceled in those in the water area Kruglaya bay and park Pobedy. The assessment of the current state metilenovoj fouling of some hydraulic structures for various coastal water areas of the Sevastopol found that the investigated structures mytilaster was prevalent. The number of mussels ranged from 403 to 14726 specimens∙m^–2. The number of mytilaster ranged from 5690 to 33802 ind.∙m^–2.
