Two new species of Freshwater Fish found

Scientists of Zoological Survey of India (ZSI) have discovered 2 new species of freshwater fish from north-eastern and northern parts of country. Both fish are hill stream fauna, measures less than 7 centimetres (cm) and are equipped with special morphological features to suit rapid water flow.

Key Findings

Both species of fish were discovered from remote areas of country. As Glyptothorax gopii was discovered from Mizoram’s Champai district near India-Myanmar border and Garra simbalbaraensis has been found from Himachal Pradesh’s Sirmour district.

As per the experts, origin or evolution of fishes in Himalayas and north-eastern parts of India is probably the consequence or after-effects of orogenic events or geological movement at various stages in Himalayas’ uplift.

Glyptothorax gopii

It is a new species of catfish found in Kaladan river of Mizoram.

Features: It measures 63 mm standard length without caudal fin (tail fin). It is dark brown on its dorsal surface and its ventral (pelvic) surface is of a yellowish-light brown.

It has been named to celebrate contribution of eminent taxonomist K.C. Gopi.

What makes it distinct from other species of genus Glyptothorax? It has an axe-shaped anterior nuchal plate (bone below dorsal fin) which is unique to it.

The elliptical thoracic adhesive apparatus and plicae (folds of tissue) present on ventral surfaces of pectoral-fin spine help fish cling to rocks.

Garra simbalbaraensis:

It was found in Simbalbara river of Himachal Pradesh.

Features: It measures 69 mm standard length without caudal fin (tail fin) and has a yellowish-grey colour fading ventrally (towards lower surface).

It takes its name from Simbalbara river.

It has a prominent unilobed and rounded proboscis with tubercles that help fish in manoeuvrability (movement or series of moves requiring skill and care).

Species of genus Gara has an evolved disc to attach to rocky surfaces.

Operation Sunrise

India has carried out Operation Sunrise to wipe out the insurgent camps planning to hit the Indian workers at the Kaladan Transit project. The Operation was reportedly carried between mid-February to early March.

Operation Sunrise

  • Operation Sunrise was a joint operation carried out by both Indian and Myanmar armies. During the operation, at least 10 camps of an insurgent group in neighbouring Myanmar were attacked.
  • The Indian Army did not cross into the Myanmar side but there was a massive mobilisation along the border, on the Mizoram side.
  • Indian side supported Operation Sunrise by providing surveillance equipment and deploying additional troops on the Indian side.
  • The target of the Operation Sunrise was the Arakan Army, an insurgent group trained by the Kachin Independence Army (KIA) which is reportedly trained by China.

India had carried out a similar operation in 2017 which had inflicted heavy casualties on the insurgent National Socialist Council of Nagaland-Khaplang (NSCN-K) group during the retaliatory fire along the India-Myanmar border.

Kaladan Multimodal Transit Transport Project

Kaladan Multimodal Transit Transport Project aims to connect seaport of Kolkata (India) with Sittwe seaport in Myanmar by sea. The project links Sittwe seaport to Lashio in Myanmar via Kaladan river through boat route and then from Lashio to Mizoram in India by road transport.

The project would reduce the distance from Kolkata to Mizoram by approximately 1000 km and thereby cut travelling time to 3-4 days for transport of goods together with providing an alternative to current route from North East to Kolkata port via chicken neck which faces heavy traffic and transportation of cargo via this route takes many days to reach port.
