Studi Ekologi Moluska Bernilai Ekonomi Pada Hutan Mangrove di Teluk Youtefa Kota Jayapura
ABSTRACT: Study of ecology
of mangrove organisms at
Yotefa Bay Jayapura has been done from
February to December 2012. The main purpose of this study is to collect
the ecological data mangrove organism focus on diversity, distribution, richness,
and similarity. The study was on
organisms which have economical values for people living at the Papua Trade Centre
area (PTC), Skyland,
and Nafri. The
data were collected
with the line
transects and quadrate methods, and
data was examined
with description on
quantitative and qualitative
methods. The result
showed that there were
7 species of
mangrove organism which
have economical values;
which were Anadara
granosa, Anadara pilula, Isognomon ephippium, Gelonia erosa, Gelonia
expansa, Pinna nobilis, and Faunus ater. The diversity indexrevealed that the highest number of species diversity was in
PTC and
Nafri area which were 1,70 and the lowest species diversity was in Skyland area which was
1, 55. The highest species evenness (E)
was occurred in skyland and
Nafri, which was 0,80 and the
lowest was in PTC which was
about 0,32. The highest abundance of species occurred in
Skyland area was G. expansa
scoring 4,9 ind/m2 and the
lowest abundance in
Nafri was P.
nobilis scoring 1 ind/m2. The
similarity index for the PTC Area, Skyland, and Nafri was on
spesies of G. erosa, G. expansa, A. granosa, I.
ephipium, and F. ater.
