Pseudoplatystoma is a genus of several South American catfish species of family Pimelodidae. The species are known by a number of different common names. They typically inhabit major rivers where they prefer the main channels and tend to stay at maximum depth, but some species can also be seen in lakes, flooded forests, and other freshwater habitats. They have robust bodies, and are important food fish. Recently, their population size has been on the drastic decline due to a variety of factors including overfishing and habitat destruction due to the construction of hydroelectric dams.

Hemibagrus punctatus, or Nilgiri mystus, is a species of fish in the family Bagridae. It was first described by Jerdon in 1849. It is endemic to east-flowing rivers in the Western Ghats of India. Of these, the species is likely only found in the Kaveri River; records from the Krishna River may actually be of H. maydelli. However, one record from the west-flowing Bharatappuzha River has been tentatively assigned to this species. The last record of this species was in 1998, and it may have experienced a population decline of nearly 100%; thus, IUCN categorizes the species as critically endangered. It is threatened by habitat degradation by excess siltation, excess fishing, and dam construction. However, based on several specimens caught by fishermen between 2011 and 2012 that likely belong to this species, as well as testimonies from local fishers, moderate populations of this species may still be extant in the region.
