The Red Canarese Barb, Hypselobarbus thomassi (Day, 1874) is an endemic cyprinid fish of the rivers of the Western Ghats of India, which has been listed as 'Critically Endangered' in the IUCN Red List of Threatened Species. Like many of its congeners, H. thomassi is poorly known with very few verified records and voucher specimens in the past decades. Based on fresh materials collected from three west flowing rivers of Kerala, we provide information on its identity, distribution, phylogenetic position, threats and conservation. An updated conservation assessment of this species following the IUCN Red List criteria is also provided. [ABSTRACT FROM AUTHOR]

Summary: The present study reports the length‐weight relationship (LWRs) of two cyprinid fishes, Hypselobarbus thomassi (Day, 1874) and Hypselobarbus kurali (Menon & Rema Devi, 1995) from River Kallada, Southern Western Ghats, India. About 182 samples of H. thomassi (10.7–60.4 cm TL) and 108 samples of H. kurali (9.8–27.0 cm TL) were collected on a monthly basis between August 2015 to July 2016 using gill nets (1.5–12.0 cm). The ‘b’ values in LWRs were determined as 2.96 for H. thomassi and 2.93 for H. kurali. No previous information is available on LWR data for these two species. [ABSTRACT FROM AUTHOR]

The present study provides the length-weight relationships ( LWRs) of two Ambassid fish species, Parambassis dayi (Bleeker, 1874) and Parambassis thomassi (Day, 1870) from River Pamba in Southern Western Ghats, India. Fishes were collected on a monthly basis between April 2014 to March 2015 using gill nets (1.0-3.0 cm), cast nets (1.0-2.0 cm) and seine nets (1.0 cm). The b values in the LWRs were estimated as 3.01 for P. dayi and 3.14 for P. thomassi. No previous information is available on LWRs for these two species in FishBase. [ABSTRACT FROM AUTHOR]

The present study describes the length-weight relationships ( LWRs) of two cichlid fish species, Etroplus suratensis (Bloch, 1790) and Etroplus maculatus (Bloch, 1795) collected from Vembanad Lake, Kerala, India during the period June 2012 to May 2013 using gill nets with various mesh sizes (3.5-9 cm) and cast nets with a 1.5 cm mesh size. The values of parameters b in the LWR equation were estimated as 2.67 for E. suratensis and 2.72 for E. maculatus, respectively. [ABSTRACT FROM AUTHOR]

This paper provides length-weight relationships ( LWRs) for three freshwater cyprinid fish species: Barbodes carnaticus (Jerdon, 1849), Hypselobarbus kolus (Sykes, 1839) and Tor khudree (Sykes, 1839) from the Chalakduy River in South Western Ghats of India. Fish samples were collected on a monthly basis between April 2011 to March 2012 using gill nets of different mesh sizes (3.5-10 cm). LWRs for these three species had not been previously reported in FishBase. [ABSTRACT FROM AUTHOR]

The article focuses on the discovery of the Piaractus brachypomus red-bellied pacu fish at the Vembanad Lake in India. It cites the need to develop solutions to prevent the spread of the fish species in natural waters. It says that the fish has the capability to thrive in several aquatic environments. It adds that the species possess a strong dentition that could harm humans and other aquatic animals and was viewed to cause economical damage to local fishers.
