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.
