Habitat and Ecology [top]
Habitat and Ecology: Found in freshwater rivers; slow moving lowland streams. Dependent on bivalves as the reproductive host.
Systems: Freshwater
Congregatory: Congregatory (and dispersive)
Use and Trade [top]
Use and Trade: Likely to be widely found in subsistence fisheries.
Threats [top]
Major Threat(s): The species is likely to be impacted by fisheries, and by pollution and dams in parts of its range. The species is reliant upon mussel hosts for its reproduction, and these are often more likely to be impacted by pollution. The specific host for the species is not known. There is general habitat loss and degradation, especially from high sediment loads from agriculture and deforestation, which impacts the bivalve host.
Conservation Actions [top]
Conservation Actions: Taxonomic work is needed to compare populations. Population and habitat trends should be monitored.
