This study investigated the environmental characteristics and macrobenthic community structures of an intertidal flat located on Yubu Island in western coastal area Yellow Sea South Korea. The site has been well known for migratory bird protection designated by UNESCO. We collected samples surface depth core sediments macrobenthos from unused saltern surrounding it July 2017. Our results demons...

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...

This study has been in order to investigate the effects of cage culture in the south of the Caspian Sea, Kelarabad. Sampling was in three direction of cages, East, West and South (the coast of Caspian Sea). For this purpose, four stations on each side of the cages was considered in terms of distance, the shadow (5 meters) to a distance of 1000 meters cages (control). Grain size analysis shows, ...

 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...

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 (...

Coastal lagoons and brackish ponds are extremely dynamic temporary ecosystems that follow natural changes throughout their geological history. The correct management of the ensures integrity proper functioning. For this reason, ecological status should be surveyed for assessing most appropriate strategies use. In present study, historical datasets collected in 2003–2004 used to investigate spat...
