Populasi dan Mikrohabitat Kepiting Genus Uca di Kawasan Konservasi Mangrove Pantai Panjang, Bengkulu
Abstract: Fiddler crabs (Uca spp.) are distributed
widely in tropical and subtropical areas in the world. They live in the sandy
and muddy bay habitats of intertidal zone. This study aimed to find species
abundance, microhabitat and population density
of fiddler crabs
in mangrove conservation
area of Pantai Panjang,
Bengkulu. The sampling was
conducted for three months started from December 2013 to February 2014.
Sampling locations were decided purposively on the area consist of four
microhabitats, i.e. sandy, muddy, muddy around decay plant roots and around
mangrove roots. Samples of Uca were collected from 1x1 m of sixty
quadrants. The results found
seven species of
fiddler crabs i.e.
U. perplexa, U.
lactea, U. jocelynae,
U. forcipata, U. triangularis, U. rosea, and U. dussumieri.
They were distributed at four microhabitats. The microhabitats of U. perplexa,
U. lactea, U. jocelynae, U. forcipata, U. triangularis, U. rosea, and U.
dussumieri were around mangrove roots and sandy, around mangrove roots, muddy,
muddy, muddy around decay plants, muddy and sandy areas, respectively. Among
those species, U. perplexa was the most abundant population whereas U. dussumieri
was the less one. Popolation density of fiddler crabs were U. perplexa
5.48 ind/m2, U. lactea 4.25
ind/m2, U. jocelynae , 1.47 ind/m2, U. forcipata 0.28 ind/m2, U.triangularis 0.18 ind/m2, U. rosea 2.17 ind/m2 and U. dussumieri 0.12
ind/m2.
