A study on the sediment preference of Diopatra claparedii was conducted by testing
the species on five different types of sediments. The species was collected on the
mudflat area in Morib, Selangor, and were brought back to UMT for experiment. Tube
building capability (TBC) & the survivability of the species on the sediments were
observed. Five individuals were tested for each types of sediments for the survivability
observation and four individuals for the TBC observation. All individuals in the TBC
observation managed to regenerate new tubes except for only one individuals in the
Coarse Sand (CS) that failed to regenerate new tubes, and eventually died. Individuals
in Very Fine Sand (VFS) showed the same survivability rate as the controlled sediment
which is 0.8, while Fine Sand (FS) showed the lowest survivability rate of all sediment
which is 0.2. This study could show the optimum sediment needed for the species that
can be used in future applications.
