| Abundance and distribution of Veneridae family in the Hendijan coast, Khuzestan province (Persian Gulf) were studied in a period from summer 2005 to spring 2006. Sampling was done seasonally with vanveen grab from 5 stations. Stations were located 0.5 mile apart and samples were collected from approximately 8 m depth. In this study 5 species of Veneridae were identified: Circenita callipyga, Gafrarium pectinatum, Bassina calophylla, Paphia gallus and Paphia textile. The abundance and percentage of frequency for each species were measured. The highest frequency of occurrence was observed in Circenita callipyga with ratio 88.69% and abundance 8668 No m-2 and other species had low ratio. Juveniles had 9.93% in ratio and 971 No m-2 in abundance. The effect of temperature, salinity and particle size of sediment as three main environmental parameters on benthos frequency were investigated. Significant relation was found in frequency and particle size between 63-125 micrometer but there was no significant relation between frequency and other factors. Diversity indices showed poor diversity of Venerid population in the north of the Persian Gulf. |
