Kelimpahan Dan Pola Distribusi Kerang Kepah (Meretrix Meretrix) Di Perairan Pantai Tanjung Balai Asahan Provinsi Sumatera Utara
This research was conducted from September – Oktober 2014 in coastal water of Tanjung Balai Asahan north Sumatra. In general the shell was a group of invertebrate animal (invertebrates) with its shape easy to be recognized. Most shell were characterized by the presence of a shell that protected the body and only a small part type was not shelled. The mussel shell M. meretrix was an importat fishery commodities as food from the sea and popular to Tanjung Balai community. Tanjung Balai Asahan coastal was one of the mussel shell M. meretrix potential in north Sumatra. This research was aims to determine the abundance and distribution patterns of mussel shell M. meretrix in the intertidal zone Tanjung Balai Asahan. The method applied on this research was survey method. Location ofthe study were divided into 2; station1was away from the settlements; while station 2 was near residential area. To get a description of the abundance distribution of mussel shell M. meretrix in the intertidal zone of the coastal Tanjung Balai Asahan, the tidal area was divided into 4 zones by dividing the tidal zone vertically, range from high tide to low tide. In each zone a sample taken 5 plot with plot size 1x1m2. Sediment sample were taken by 3 points in each zone, and rolled into one, so that amount of sediment sample by 4 sample at each station. Sample taken shell, sediment, measurement quality of the measured temperature, salinity, pH, brightness. The result showed that the average abundance ranged from 1.6 ind/m2 to 7 ind/m2. The pattern of distribution in the study area tend to cluster. Based on the calculation of the t test at each station and each zone F test on the abundance of mussel shell M. meretrix showed equally not significantly different. Keywords: Mussel shell, abundance, sediment, pattern distribution, Tanjung Balai Asahan.
