Not sure if this will help you in your situtation, but here goes.

The marsh here is mostly soft acidic tannin stained waters. Gammurus
usually live near any kind of current to be found, which unless it is
flooding is very slow somtimes unnoticable current. The favored areas to
find them are fine roots of plants in the water, and under rocks in the
strongest current areas. It seems the fine roots are the most important
component to finding them. Thicker dead grasses and rice usually hold more
amphipods. Any fine root material will work, terrestrial plants with the
roots in the water, or aquartic plants with the same roots. Something
closely resembling hair would be better than coarser roots. They seem to
like it dark so under cut banks and floating vega mats are also the most
concentrated masses of gammurus in the areas they frequent.
