W. Major et al., A VACUUM WATER PUMP FILTRATION SAMPLER FOR THE COLLECTION OF AQUATIC INVERTEBRATES/, Journal of freshwater ecology, 13(3), 1998, pp. 361-363
We describe construction of a vacuum water filtration device for the c
ollection of aquatic invertebrates. The unit is assembled from materia
ls found in most laboratories and hardware stores. Its simple design a
llows for the extraction and filtration of aquatic invertebrates from
the water column within open water as well as among submersed or emerg
ent vegetation.
