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. cunma and O. feae, were characterized. Meristic study showed differences in anal fin rays count and lateral line scales. Morphometric analysis revealed significant differences amo...

Pengba fish, Osteobrama belangeri is a freshwater inhabitant, highly endemic, threatened and economically important minor carp for its food value. In the present investigation, population structure of O. belangeri was examined using mitochondrial ATPase 6/8 gene from geographically distinct locations along the Indo-Burma biodiversity hotspot. A tot...

Aim : Shalynai fish, Puntius shalynius is an inhabitant of freshwater, endemic and threatened hill stream fish of North-East India. The present work aimed to study the ultrastructural and functional characteristics of P. shalynius intestine, as addition to studies on nutritional requirement. This fish is considered an important species for ornament...

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...

Relative length of gut, gastrosomatic index, index of preponderance and gut contents were analysed to determine the feeding habit of Pethia shalynius (Yazdani and Talukdar 1975), an endemic and threatened hill stream fish of Northeast India. A total of 577 individuals were collected from the Umiam River, Barapani, Meghalaya for the present analysis...

Pethia shalynius is an important hill stream fish having both food and ornamental value. A total of 209 samples ranging from 4.20 - 6.90 cm total length, collected during 2010 - 2011 were used for the morphometric and meristic studies. Most of the morphometric characters of the species were found to be genetically controlled, rather than environmen...

Three species of fishes, viz., Bagarius yarrelli, Parambassis lala, listed Near Threatened and Hemibagrus menoda, Least Concern by IUCN, respectively belonging to the families Sisoridae, Ambassidae and Bagridae have been newly recorded from the upper reaches of the Brahmaputra and Surma-Megna river basins of Meghalaya. Diagnostic characters and bri...

This paper reports on the condition factor and relative condition factor of Puntius shalynius in Meghalaya. The samples were collected during the period 2010-2011 from two different study sites, a stream and a pond. The total length and weight of male and female fish were recorded. The mean condition and relative condition factor showed seasonal va...

The surface microstructural features of scales, gills, upper and lower jaw of Puntius shalynius, an endemic fish of Meghalaya was investigated through scanning electron microscopy to understand the structural details of the aforementioned organs in relation to general biology of the fish species. The study is relevant in view of the fact that gills...

The present investigation gives the length-weight relationship (LWR) of Puntius shalynius in Meghalaya, India. The samples for the study were collected from Umiam river. The value of the exponent ‘b’ in the LWR was less than 3, with 0.885 for males and 1.616 in females. This shows that the species exhibit allometric growth pattern. There was no dif...

Meghalaya situated in the northeastern region of India, is endowed with a rich variety of flora and fauna. A survey on the icthyofauna in seven districts of Meghalaya carried out from January 2008 to July 2009 has revealed 68 species belonging to 45 genera, 20 families and 6 orders. Cyprinidae were the most dominant group represented by 30 species...
