Ukuran Dan Sebaran Atactodea Striata Dan Donax Faba Pada Zona Intertidal Di Desa Sambungo Kecamatan Silaut Kabupaten Pesisir Selatan Provinsi Sumatera Barat
Abstract
This research was carried out in January 2021 in the Intertidal Zone of Connecto
Village, Silaut District, Pesisir Selatan Regency, West Sumatra Province. The
purpose of this study was to determine the size variation of the bivalve, the
distribution pattern of the bivalve, the effect of the type of sediment fraction on the
size, and the distribution of the bivalve in the intertidal zone. The method used in this
research is a survey method which is carried out by direct observation and sampling
in the field. Bivalve samples obtained were identified at the Marine Biology
Laboratory and Sediment Fraction Analysis was carried out at the Chemical Analysis
Laboratory, Faculty of Fisheries and Marine Affairs, University of Riau. Based on the
results of the study, the highest number of bivalves was at station 1 as many as 11
individuals. The distribution pattern of macrozoobenthos in the intertidal zone of
Connecto Village ranges from 3.86 to 5.07 with the highest morisita index value
being at station 1. The highest percentage of sediment fraction is 96.53% in the lower
zone and the highest organic matter content is at station 1 of the lower zone. with a
total percentage of 6.65%. Based on the criteria for the morisita index at station 1,
station 2, and station 3 with an Id>1 value, it can be concluded that the distribution of
Bivalva in the intertidal zone in Connecto Village is clustered.
Keywords: Bivalve, distribution pattern, Fraction type, South Coast.
