Freshwater fish fauna of Koyna River, northern Western Ghats, India

Ichthyodiversity of the Bangshi river, Savar, Dhaka

“…Identification was done based on keys used by Bhuiyan (1964), Talwar & Jhingaran (1991), Shafi & Quddus (2001), Rahman (2005) and finally recorded in the museum of the Department of Zoology, Jahangirnagar University. All collected data were then used to calculate "Relative Abundance" of a particular fish species" by following the method of Jadhav et al (2011) with slight modification i.e., the relative abundance of the fish was classified into three categories namely Very common (67-100%), Common (34-66%), and Rare (1-33%) on the basis of their availability in total catch. Consequently, the statuses of recorded fishes were determined following IUCN Bangladesh (2000).…”

Diversity, threats and conservation of catfish fauna of the Krishna River, Sangli District, Maharashtra, India

“…Dahanukar et al (2012) reported 11 species of catfish, out of 57 species of freshwater fishes of Indrayani River, a tributary of Bhima River. Jadhav et al (2011) reported 10 species of catfish of a total 58 species, close to the present study area; their data is confined only to Koyna tributary which is a major tributary of Krishna, which joins it at Karad City. Our study area starts from Preeti Sangam and extends towards the east where Yerala, Warana and Panchaganga tributaries further join the Krishna River.…”

“…This species was reported by many ecologists in the Krishna River system. Panchaganga River near Kolhapur (Kulkarni 1952;Kalawar & Kelkar 1956), Krishna River Islampur (Kulkarni 1952), Krishna River near Sangli (Jayaram 1995), Koyna River near Patan (Jadhav et al 2011), Indrayani River near Kamshet (Dhanukar et al 2012).

The most recent references of fish species numbers were taken into account and were estimated.…”
