The density and distribution of Lingula sp. in Aceh Northern Shore

Abstract

Abstract The information of the density and distribution pattern of Lingulasp. in Aceh Shore is infrequently recorded. Since Lingulasp. has important roles in ecosystem, the study of species density of Lingulasp.and its distribution pattern was conducted in two sites of Aceh northern shore which were UjongPancu Beach and Syiah Kuala Beach. The aim of this study was to figure out the density and distribution pattern of Lingulasp. Sampling was carried out by designing nine 1,0m x 1,0m plots at each station during April – May 2018. Results of study revealed that Lingulasp. at UjongPancu Beach is less denser than at Syiah Kuala Beach. The density range of Lingulasp.at UjongPancu Beach was 1.56 ind/m2- 2.89 ind/m2 while the density of Lingula sp. at the Syiah Kuala Beach was 3.78 ind/m2-5.44ind/m2. The distribution pattern of Lingulasp. at both stations was found as uniform distribution.
