ANALISIS KELIMPAHAN PLANKTON DAN PERTUMBUHAN KERANG KEPAH Polymesoda erosa (Solander, 1786) YANG DIPELIHARA PADA TAMBAK DI DELTA MAHAKAM
ABSTRACT: This research
was aimed to
analyze the relationship
between plankton abundance
and morfometric growth of Mud Clam (Polymesoda erosa). The study was
located in an idle brackish water pond in Mahakam Delta, by culturing
Polymesoda erosa in small scale. Grouping random design was applied for
sampling. Treatment was divided into factor A and B. Factor A is related to
shell size: size I (40 – 60,99 mm), II (61 – 80,99 mm) and size III (81 – 100
mm). Factor B is indicating to study
location with vegetation
(Rhizophora sp) and
no vegetation. In
order to analyze plankton
abundance, a quantitative
descriptive analysis was
applied, in addition
of ANOVA test to analyze the growth. The result indicated that between
two study ponds is different. The
number of plankton per
liter water from vegetated pond
has more plankton individual than the
sample from non-vegetated
pond. The applied
treatment on study
ponds and shell
size determined the morfometric growth and biometric. The growth of
shell length is faster than that on
height and thickness.
The growth of
mud clam in
vegetated ponds relatively
better that the pond without vegetation.
