Zoobenthic Crustaceans and Seasonal Distributions in Northern Coast of the Absheron Peninsula (Caspian Sea)

Abstract

The aim of this study was to determine the zoobenthic crustaceans in northern coast of the Absheron Peninsula of the Caspian Sea. Samples were collected using a scoop net, a scraper tool and a Petersen dredge at 0.5-2.5 in depths from 23 stations in eight transects located in northern coast of the Absheron Peninsula of the Caspian Sea between 2008 and 2010. A total of 30 benthic crustacean species belonging to 6 orders were recorded during the course of this study. Amphibalanus improvisus Niphargoides caspius and Palaemon elegans were the dominant species during the study. Primary hydrographic conditions, such as temperature (7.3-27.0 degrees C), salinity (12.3-12.9 parts per thousand), dissolved oxygen (4.42-7.54 ml L-1) and pH (4.2-8.1) were recorded at each sampling station.
