Abstract:
The study of length-weight relationship of Cerithidea cingu!ata was done in order to
assess mud snail that have been founded in different habitats. The relationship of shell
length with wet weight of shell of gastropod species Cerithidea cingulata from different
habitat such as mangrove forest and intertidal flat area of Pengkalan Gelap, Setiu were
measured. The sampling was conducted monthly for one year. The relationship of shell
length and dry weight also measured in order for comparison with length and wet weight.
Growth of the mud snail Cerithidea cingulata from different habitat of mangrove forest
area and intertidal flat area were measured and compared. The length-frequency data of
Cerithidea cingu!ata for the both habitats were applied with Von Bertalanffy growth
function. Then, by using electronic analysis (ELEF AN) in FiSA T program the growth
parameters were determined. The maximum length of Cerithidea cingu!ata that have
been recorded during sampling for habitat of mangrove forest and intertidal flat area were
2.6 cm and 2.7cm. However, asymptotic length, Leo of VBGF estimates that Cerithidea
cingu!ata could attain a maximum growth of 2.78 cm even they were living in different
habitat. While VBGF growth constant, K of Cerithidea cingu!ata for habitat of mangrove
forest were 0.810 year 1 while habitat intertidal flat area were 1.10 year.
