ENGINEERING DEVELOPMENT OF SAMPLING MAKROBENTHOS : SELECTION OF EQUIPMENT AND PREPARATION
Makrobenthic animals are invertebrates that relatively small (at least 500 µ) 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 sediment (infauna). Therefore, it needs proper method of collecting these animal. The procedures that need to be considered when collecting samples of macrofauna marine animals are sampling techniques, the tipe and size of the sampling tool, mesh size and methods of preservation and fixation.
