Qısa məlumat

The article is devoted to the study of the species composition and distribution of macrozoobenthos in the coastal zones of the Azerbaijani sector of the southern Caspian Sea. The study (2008-2009) found 56 species belonging to seven systematic groups. The maximum number of species was observed in the spring and summer season (from 33 to 54 species), and the minimum - in the autumn season (from 25 to 30 species). The average annual biomass of macrozoobenthic organisms varied in the range of 63.33-67.69 g / m2, and the number of 306-323 ex/m2. The maximum development of organisms was observed in summer (81.07 g / m), the minimum-in autumn (48.10 g / m2). In terms of species and quantity, the fauna of the silt - shell biotope is the richest, where the total biomass ranges from 93.24 to 94.83 g / m2, with a population of 275-285 species/m2.
