DNA barcoding facilitates quick species identification and enhances taxonomic data for efficiently classifying known and unknown creatures using DNA sequences. Using this technique, non-taxonomists may be able to easily identify the species which could support biodiversity and conservation studies. Bangladesh, a small South Asian country, harbours...

New methods are required for biomonitoring of poorly known tropical ecosystems, but biological assessments of environmental status are limited by insufficient information on taxonomy, composition and ecology of local communities. The current work applies DNA‐based assessment to establish the impact of various types of anthropogenic disturbances on...

Biodiversity hotspots of the world are increasingly exposed to anthropogenic pressures and resulting ecosystem breakdowns. However, biotic surveys for ecological status assessment are rarely conducted in poorly characterised, yet highly diverse ecosystems in the tropics and subtropics. Here, we addressed the challenge of developing a monitoring sys...

We sequenced the standard DNA barcode gene fragment in 694 newly collected specimens, representing 243 species level Operational Barcode Units (OBUs) of freshwater fishes from Bangladesh. We produced coi sequences for 149 out of the 237 species already recorded from Bangladesh. Another 83 species sequenced were not previously recorded for the count...

Five species of Badidae are reported from Bangladesh, with morphological diagnoses and mitochondrial DNA sequences (cytochrome b, cytb; and cytochrome c oxidase subunit I, coi). Dario kajal is recorded from Bangladesh for the first time with a precise locality. Badis badis is reported from several localities in central Bangladesh. Badis chittagongi...

Osteobrama cotio is considered to be a widespread species in India and Bangladesh. Mitochondrial DNA (COI, 16S rRNA) shows that populations from the Meghna River, Karnafuli and Sangu Rivers, Narmada River, and Godavari River are genetically distinct from each other. No morphological differences were found to separate Meghna and Karnafuli+Sangu popu...

Laubuka tenella is a new species characterized by the colour pattern, consisting of short dark vertical bars anteriorly on the side, and a dark lateral band posteriorly on the side, combined with a relatively short pelvic fin and 29–30 lateral-line scales. It is separated from other Laubuka analysed by minimum 9 % uncorrected p -distance in the mit...

Four species of Devario are recorded from Bangladesh: D. aequipinnatus, D. anomalus, D. coxi, new species, and D. devario. Devario aequipinnatus has a wide distribution in northern India and Bangladesh. Devario coxi, from southeastern Bangladesh near Cox’s Bazar, differs from D. aequipinnatus in mtDNA (COI, p-distance 1.8%), colouration, proportion...

The Croaking Gourami, Trichopsis vittata (Cuvier, 1831), is native to Southeast Asia and Sundaland, with introductions reported from USA, Philippines and India. The species was found by us in Myanmar (1997 and 2013), and Bangladesh (2014 and 2016). DNA analysis supports the view that T. vittata is a species complex. Specimens from Bangladesh, Myanm...

Garra mini, new species, is described from the Shuvolong, Shailopropat and Chingthong waterfalls in the Karnafuli and Sangu River drainages. The largest specimens recorded is 46.8 mm SL and specimens over 40 mm SL have reached reproductive size. Alongside G. ethelwynnae (28 mm SL) and G. poecilura (44.5 mm SL), G. mini is one of the smallest specie...

Danio annulosus, new species, is described from a small pool below the Shuvolong Falls in the Kaptai Lake system in Bangladesh. It shares with chain danios (D. assamila, D. dangila, D. catenatus, D. concatenatus, and D. sysphigmatus) a colour pattern consisting of series of dark rings with light interspaces along the side, complete lateral line, 14...

The native distribution of the small labyrinth fish species Pseudosphromenus cupanus includes southern India and Sri Lanka. According to literature it has a range including also Pakistan, Bangladesh, Myanmar, Malaysia, and Indonesia (Sumatra) but there are no voucher specimens or reliable observations from those areas. The distribution record of P....

Bangladesh is a country of 1,47,570 km2 of mostly flat topography, but about 12 percent is hilly. The hilly areas are confined to the northeast and the southeastern parts of the country bordering India and Myanmar. Hill streams are highly variable and very important for the study and understanding of the aquatic biodiversity of Bangladesh. Hillstre...

The present study was carried out to determine the level of bioaccumulation of some heavy metals in a freshwater fish Ayre ( Sperata aor Hamilton, 1822) collected from Rajfulbaria (23°48′56.36″ N and 90°14′54.04″ E) of Dhaleshwari river. Four heavy metals, namely chromium (Cr), copper (Cu), lead (Pb), and cadmium (Cd) were selected for this study....

The present study was performed on induced breeding of pond reared Thai koi, Anabas testudineus (Bloch, 1792) during the month of February to July 2007 at Udayan Matshya Khamar, Trisal, Mymensingh and at Fisheries Laboratory, Department of Zoology, University of Dhaka. The early March to early April were found best period of spawning. Some individu...

Study on polyculture of major carps with koi (Anabas testudineus) was performed during the month of March to September 2009 in beel Simulia and Baelai located at Kaliganj upazila in Gazipur district to observe the comparative growth and production of fishes cultured. Catla (Catla catla), Rui (Labeo rohita), Silver carp(Hypophthalmichthys molitrix),...

A survey was conducted in some wetland ecosystems located at the two Upazillas namely Shibalaya and Harirampur in Manikgonj District of Bangladesh during the period from January 2004 to January 2005 with a view to assess the status of freshwater crab resources in the area. The study was made on species diversity including its taxonomic position, mo...
