A survey has been made during February 2010 to know the pattern of molluscan fauna inthe mangroves located along the Karangad estuary. During the present investigation in the researcharea, 25 species of molluscs were recorded. They belong to 14 genera, 10 families and 5 orders. Inthe study area, 13 species of gastropods namely, Cerithidea fluviatilis, Terebralia palustris, Cerithiumcitrinum, C. scabridum, C. obeliscus, Littorina scabra, L. undulata, Planaxis sulcatus, Drupamargariticola, D. heptagonalis, Thais rudolphi, T. bufo, and T. tissoti and 12 species of bivalves –Gafrarium tumidum, G. pectinatum, Crassostrea madrasensis, Mactra cuneata, Tellina ala, T. bruguieri,Saccostrea cucculata, Modiolus metcalfei, M. tulipa, M. traillii, Meretrix meretrix and M. casta - wererecorded.

    ABSTRACT: Mangrove or Mangal vegetation are typical wetland ecosystems found in coastal deposits of mud and silt throughout the tropics and some distance into the sub-tropical latitude. Species diversity, distribution, seasonal abundance in population and behavioral responses of mangrove associated molluscs (gastropods and bivalves) were investigated in two mangal areas: Sandspit and Korangi, along the Karachi coast of Pakistan. For sampling, a fixed route was followed throughout the study period and the samples were collected and observations were made from HTZ to LTZ. Fourteen species of molluscs (5 Prosobranchia; 6 Pulmonata; 1 Opisthobranchia and 2 Lamellibranchia) belonging to ten families were recorded. Family Ellobiidae, Potamididae, and Onchididae were found extensively distributed in both sites. All the recorded species are belonging to the epifaunal mode of life. Analysis of the data shows that ten of the recorded species are common to both sites, while four are exclusively found at the Korangi site. Seven of the representative species are exclusively mangrove associated; five are common to mangrove and non-mangrove areas, while two are non-mangrove dwellers. The low species diversity can be attributed either to the study techniques, a small number of study sites or possibly to the geographical locations of the study sites. Seasonal variations were noticed in species diversity and density distribution, indicating higher values in summer and autumn and lower in spring and winter.

    • "Mundra as sandy-muddy habitat contain less species diversity. The result somehow does not match with the earlier work done in India which suggest mangrove ecosystem contain more diversity of Gastropod fauna (Khade and Mane, 2012; Venkatesan et al., 2010) Shannon diversity index is high during winter this could be due to low temperature and turbidity coupled with stable environment of this season. Similar observation was recorded by Saravanakumar et al., (2007) while working on benthic macrofaunal assemblage in the similar area of our study site. "

    ABSTRACT: The present study was conducted at three sites having different coastal characteristics in Northern Gulf of Kachchh namely Mandvi, Mundra and Sanghi. In this study a total of 36 species of 18 families of gastropods were recorded from Gulf of Kachchh of which Sanghi, Mundra and Mandvi recorded 17, 13 and 25 species respectively. The species density of 170 and 472/sqm was observed at Sanghi during summer and monsoon 2008-09 respectively while in Mundra highest density of 1207/sqm was observed during winter 2007-08 and lowest of (267/sqm) during summer 2008-09 was recroded.The species density at Mandvi ranged from 346 to 1003/sqm. The following paper presents the diversity index and distribution pattern. Species like Thias rudolfii and Cerithidea cingulata were observed during all seasons at all stations. The dominant species were Cerithidea cingulata,, Cerithidea fluviatilis, Umbonium vestarium and Assiminea sp. showed more than 200 no/ Shannon diversity index H were calculated for the stations in all three stations. The Highest and lowest value of Shannon index H 1.37 and 2.68 were recorded at Mundra and Mandvi during winter 2007-08.

    ABSTRACT: Intertidal distribution of Cerithium scabridum was studied on rocky Intertidal areas at Sutrapada (SP), Dhamlej (DH) and Kodinar (KO) along the coastal Saurashtra, Gujarat, India. Total 10 Line transect intercepted with 0.25 m2 quadrate were laid perpendicular to the shore line at each study site every month (December, 2011 to December, 2012). Total 6 quadrates (0.25 m2) were laid randomly per line transect from upper to lower intertidal mark for the quantification of the species. Maximum abundance of the C. Scabridum was observed in upper intertidal zone of all the study sites. Ecological attributes like abundance, density and frequency of occurrence of species were also calculated and they exhibited significant spatio-temporal variations at different study sites. Seasonal variability of sea water parameters like sea water temperature, salinity and pH were also studied and correlated with ecological attributes of species. Sea water temperature showed significant correlation with mean seasonal abundance of the species at all the study sites (SP: R2=0.77, P<0.05, DH: R2=0.91, P<0.05, KO: R2=0.78, P<0.05). In the present study, It was observed that seasonal changes in abiotic factors and chemical properties of sea water has prominent effect on the intertidal distribution of the species.
