Abundance of obtuse horn shell Cerithidea obtusa (Lamarck, 1822) in Mon coastal area of Myanmar


Author(s): Yin Nwe OO and Naung Naung OO

Abstract: The study on the abundance of obtuse horn shell Cerithidea obtusa (Lamarck, 1822) was conducted in estuarine water of Mon coastal area with the aim to get more effective data for shell fishery ecology aspects in this area. Shell samples were collected from Ahlyat coastal water in the north, Zeegone coastal water in the middle portion, and Sitaw coastal water in the south of Mon coastal water during the period of March 2018 to February 2019. A total of 1287 individuals/m2 of obtuse horn shells were collected in the study areas. Zeegone coastal water has the highest abundance and also the highest average number per station. Sitaw coastal water and Ahlyat coastal water were the second and third ranks. Based on percentage frequency of occurrence, Sitaw coastal water was the highest percentage followed by Zeegone and Ahlyat. The relationships between obtuse horn shells and constancy have not been different due to positive condition of shell abundance in three sampling areas. Regarding to shell assemblage in Mon coastal water, based on transect and quadrat abundance, it illustrated the patchy distribution of the majority of obtuse horn shell because the stations appearing similarity in shell groups and their abundance tended to be located adjacent to each other.
