Abstract:
The present study is a first attempt to examine sponge
distribution in the Persian Gulf (Iranian costs) and suggests that physical
and biological factors influence the sponge distribution patterns in Hengam
Island. The purpose of this study is to provide patterns of sponges distribution
and depth influence on sponge abundance and biomass on the Hengam Island.
Surveys of sponge distribution were conducted June 2006 and February 2007
at 5, 10, 15 and 20 m depths sites in two locations: East and West of
the Hengam island. Abundance and biomass of sponges species were surveyed
at different depths on the Hengam Island in the Persian Gulf. All data
on sponges species number and abundance and biomass in each region of
Island were taken by SCUBA diving. Transect sampling in this area revealed
distribution of sponges species. The sponges species in this area consist
of Callyspongia clavata, Callyspongia vasselli, Hyrtios
erectus, Haliclona sp., Leucetta sp., Ircinia echinata
and Dysidea cinerea. Abundance and biomass of sponges in Hengam
Island increased at 15-20 m depths.
