To estimate the biomass and secondary production of macrobenthos in Khore-e-Mousa creeks, 216 sediment samples were taken. The sampling period started in 1996 and terminated in 1997. A bimonthly sampling strategy was adopted. The samples were taken by Van-Veen grab (0.1 m2) from the beginning, middle and end of each creek (Khor). To estimate the biomass of the macrobenthos, the Crisp method (19...
Abstract Taka Bonerate waters are the third largest atolls in world, rich marine biodiversity, natural structures and aesthetics. Seagrass beds these grow well on small islands, one of coastal ecosystems that support biodiversity have many benefits for humans economic, social cultural aspects. This study aimed to examine diversity, distribution, abundance macrobenthos several islands National P...
The classic paradigm, not always unequivocal though, that seagrass macrobenthic abundance and diversity are greater than those in adjacent unvegetated areas, was tested a Mediterranean lagoon for which evidence is lacking. We compared the community structure species composition of assemblages three distinct areas Mistras Lagoon (Sardinia, Italy) dominated by i) Cymodocea nodosa (Cym), ii) mixed...
The present work has been carried out to investigate the probable effects of fish cage culture on benthic communities as a pollution and stress indicator and to evaluate the biotic health condition using BOPA index, in Ghazale Creek (Khowre-Mussa - Persian Gulf). Monthly sampling from 4 stations was carried out from June 2007 to March 2008 (during nine months). Stations were selected from unde...
