Reproductive cycle of the endemic and threatened fish Puntius shalynius (Cypriniformes: Cyprinidae) in Meghalaya, India.

Puntius shalynius is a highly endemic freshwater minor carp that is economically important and is threatened because of its ornamental value. The present investigation evaluated this barb gonadal maturation, based on morphology and spawning of this species in the Umiam river, Meghalaya, India. The population of this indigenous fish has declined due to its fragmented distribution and exploitation as an ornamental fish.

Characterization of threatened endemic fish Osteobrama belangeri (Valenciennes, 1844) and related species from North-East India based on morphological and molecular analysis.

Four species of the genus Osteobrama collected from five different sampling sites of Chindwin and Barak river basin of North-East India, namely O. belangeri, O. cotio, O.

Genetic divergence in natural and farm populations of Pengba fish, (Valenciennes, 1844), an endemic fish of North-East India derived from mtDNA gene.

Pengba fish, is a freshwater inhabitant, highly endemic, threatened and economically important minor carp for its food value. In the present investigation, population structure of was examined using mitochondrial gene from geographically distinct locations along the Indo-Burma biodiversity hotspot. A total of 80 individuals were collected belonging to natural and farm populations.
