PENGEMBANGAN TEKNIK PENGAMBILAN SAMPEL MAKROBENTHOS: SELEKSI ALAT DAN PREPARASI
ABSTRACT: Makrobenthic animals
are invertebrates that relatively small (at least 500 ยต ) and have short life
spans, and play an important role as secondary producers in the structure of
the food chain in the water ecosystem. They inhabit substrates/sediment at the
bottom of the water column, either at the surface (epifauna) or in the sediment
(infauna). Therefore, it needs proper method of collecting these animals. The
procedures that need to be considered when collecting samples of macrofauna
marine animals are sampling techniques, the type and size of the sampling tool
, mesh size , and methods of preservation and fixation . In carrying out a
study to determine the level of environmental disturbance aquatic ecosystems ,
in addition to disturbed areas , we need to use the control or reference areas
for comparison . This area is ideally a region relatively undisturbed by human
activity or environmental disturbance is assumed not to occur. Areas that are
ecologically potentially disturbed areas can be cultivated fish / shrimp ponds
in coastal systems , aquaculture floating net cage systems in a river or lake,
disposal area (outlet) of industrial waste , etc. . While the reference
area/control can be in the coastal mangrove areas , water areas without any
human activities, and upstream river that are at least 1 km away from the
disturbed area.
