IUCN lists Hump-backed Mahseer as Critically Endangered

International Union for Conservation of Nature (IUCN) has listed Hump-backed Mahseer as Critically Endangered in the Red List of Threatened Species.

Hump-backed Mahseer

The Hump-backed Mahseer is a species of freshwater ray-finned fish and is referred to as tiger of the water. The Hump-backed Mahseer is found only in the Cauvery river basin including Pambar, Kabini and Bhavani rivers. There are about 16 species of mahseer in India.

There is a need for strong willingness and cooperation from a range of stakeholders in three states of Kerala, Tamil Nadu and Karnataka across the River Cauvery which is one of India’s most contested rivers.

Shoal, an international organisation working to conserve freshwater species has initiated ‘Project Mahseer’ in collaboration with other stakeholders to enable conservation action for the hump-backed mahseer.

Hornbill

Great hornbill which was earlier categorised as “Near Threatened”. It is now “Vulnerable” due to high hunting pressure coupled with habitat loss and deforestation. The wreathed hornbill has moved from “Least Concern” to “Vulnerable” by IUCN.

Threats to Bumphead Parrot Fish in Andaman

A study has shown that Fishing, coral reef degradation threaten parrotfish in Andaman.

Fact Box: Bumphead parrotfish

Scientific Name: Bolbometopon Muricatum

IUCN Status: Vulnerable

Findings of the Study

  • Protection of coral cover along the existing protected marine areas in the Andaman and Nicobar islands is necessary for the conservation of the endangered Bumphead Parrotfish.
  • Large body size, aggregating behaviour and limited activity at night make Bumphead Parrotfish an easy target for spear-fishers.
  • Further slow growth and low replacement rates have resulted in population declines across the Indo-Pacific and the Red Sea regions.
  • Bumphead Parrotfish occurs unevenly, with most sightings from only two islands, and with an apparently very small density.
  • Freediving spear-fishers exclusively target the aggregations of this fish during the night.
  • The presence of a protected area, live coral and algal cover, significantly influenced the distribution and abundance of Bumphead Parrot Fish.
  • Incidental catch by fishers and degradation of coral reef habitats are two potential threats to the species.

The Study calls to ban night fishing for the species and to implement regulations regarding reef fishing.
