Abstract:

The current study presents data from

research conducted in Mangalia military port, in

the period November 2008 - February, March, and

April 2009.

An analysis of percentage composition of

the invertebrates’ populations is done in the paper.

Taxa belonging to at least 10 major groups were

found, either on mobile substrata, either on rocky

one, sometimes covered with macrophyte algae.

The data were used in the evaluation of some

synecological indices, as frequency (F %), average

density (D avg ind. • m-²), for each of the studied

stations.

Correlation between variation of the

number of taxa and density depending on type of

substrata was done.

The ecological significance index WD and

its correlation with the rank was also calculated,

showing that, in the studied area, oligochaetes,

nematodes and harpacticoids are considered as

characteristic groups, holding, in order, the first

three ranks.

Keywords:

Black Sea, Mangalia Lake, port, benthic, invertebrates’ populations, qualitative, quantitative analyzes.
