| dc.description.abstract | With the characteristics of the physical and chemical environment in aquatic ecosystems,
as well as the organisms there, conducting research on these ecosystems requires special
equipment. The equipment used for sampling aquatic biota includes surber nets, grabs (eg Ekman
dredger), plankton nets, water sampling bottles, and fishing nets. Surber net is used for sampling
of benthic biota in shallow water and grab is used for sampling of benthic biota in deep water and
substrate. Plankton nets and water sample bottles were used for sampling planktonic organisms,
then fishing nets for fish sampling. For microalgae attached to the substrate (rocks, aquatic plants,
or other materials), then the sampling will be taken by brushing the surface of the substrate.
Ecological data of aquatic plants can be collected using the sample plot (1x1 m) method. | en_US |
