Ecological study of the Gastropoda of the intertidal zone of Kangan and Dayer townships.
This study is carried out in order to identify and determine diversity and density of Gastropods of intertidal zone of coastal field of Dayer and Kangan townshipes in 8 stations during Autumn and Spring seasons in 2015 Sampling Gastropods was carried out using quadrate(50×50cm) with three repetitions in each station Samples collected were fixed by using 4% formalin and transported to the laboratory and counted and identified Physicochemical properties of water such as temperature, pH,dissolved oxygen (DO) and water salinity were also measured in each station The identified samples were from 19 species and 10 families Most identified species in studied stations were from Neritidae,Trochidae,Muricidae and Acmaeidae families The result of Shannon and Simpson index showed significant differences between sampling seasons and sampling stations Moreover,the Margalof index showed significant difference between sampling stations (P<0/05) and showed no significant difference between season(P>0/05) According to the identified species and also index used in order to determine water quality (Welch) studied stations in shores have water with average and rather poor quality
