Fish Larvae Assembelge in the Northwestern Coast of the Persian Gulf: Khure Mussa Channel
Authors
Abstract:
Ichthyoplankton data provide a base for research into population dynamics of major fishery species. Information on ichthyoplankton ecology forms an important component of stock assessment and fishery management plans. Also, nursery areas are important regions for the recruitment success of fishery stocks and as such, conservation of these areas is a key part of fishery management. Temporal distribution and composition of ichthyoplankton of in Northwest of the Persian Gulf were analyzed. Khure Mussa Inlet is affected by direct and indirect human activities related to petrochemical plants, harbor facilities and other economic ventures. Samples were taken from eight stations during March 2007 to April 2008.A total of 9440 larvae were collected. The highest density of larvae was observed in April 2008 (1288.88±610.32 larvae/10m2). Higher mean densities occurred during the warmest month. Fish larvae from 23 families were identified Gobiidae, Clupeidae, Sparidae, Sciaenidae and Sillaginidae were the most representative during the study period. Temporal variations in abundance of larvae showed different reproduction patterns for species. Furthermore, the spatial distribution was different for larvae. Cluster analysis using the Bray-Curtis similarity index revealed well-defined groups of stations and assemblages of larvae. For visualizing the results, spatial distribution and density data were shown on regional maps using GIS software.

Fish Bile as Biomarker of Total Petroleum Hydrocarbon Pollution in the Khure Mussa – Persian Gulf
Total Petroleum Hydrocarbon ( TPH ) are environmental contaminants that are released into the marine environment through oil spills, industrial and domestic activities. TPH are readily transformed into more hydrophilic metabolites, which are accumulated in bile. Thus fish bile can be used as a biomarker of exposure of fish to TPH in the marine environment. in this study several stations were se...

Khuzestan coastal waters have high fisheries potential and ecological importance. Since different sources of stress exist in this area, the present study was conducted to evaluate ecological quality and to determine health status in Khuzestan coastal sediments based on benthic communities and their biological parameters. Seasonal sampling was done from 20 creeks of Khur-e-Mussa area in Khuzesta...

15 صفحه اولEstimation of target hazard quotients for metals by consumption of fish in the North Coast of the Persian Gulf, Iran
In the residential area of the North Coast of the Persian Gulf, consumption of fish is a possible source of exposure to heavy metals and other pollutants, all of which may act as potential risk factors for serious syndromes and fatal diseases. Health risks associated with Pb, Cd, and Hg were assessed based on the target hazard quotients (THQ), which can be derived from concentrations of heavy m...
