Struktur Komunitas Bivalvia Pada Zona Intertidal Pulau Pasumpahan Kota Padang Provinsi Sumatera Barat
ABSTRACT
Bivalvia is a class of the Mollusca phylum. Bivalvia is also known as Pelecypoda and
Lamellibrankhiata. Bivalvia occupies an area of the intertidal zone, one of which is in the
intertidal zone of Pasumpahan Island. But information about bivalves in the area does not
exist. To know/understand the information about the density and distribution pattern of
bivalves on Pasumpahan Island, this research was conducted in January 2022. The
sampling area was in the intertidal zone of Pasumpahan Island. Sampling was carried out
at three stations, each station was divided into three transect. Bivalve sampling was carried
out using a 1mm x 1mm sieve. The movement of bivalves to the gravel substrate is very
fast to avoid splashing waves. Bivalves samples were then identified. The density of
bivalves in the intertidal zone of Pasumpahan Island ranged from 1.78-3.56 Ind/m2. Station
2 has a higher density of bivalves, namely 3.56 Ind/m2, the calculation of bivalves in the
intertidal zone of Pasumpahan Island obtained bivalves distribution pattern data is groups.
Keywords: Bivalvia, Intertidal Zone, Density, Distribution Patterns, Pasumpahan Island.
