Fishes of the river Padma, Bangladesh: Current trend and conservation status

Abstract

The Padma River is one of the longest rivers and it is believed to be an important spawning and feeding ground for riverine fish species of Bangladesh. This study was conducted from February 2013 to January 2014 and with a view to revealing the diversity of fish fauna in the river. A total of 71 species were recorded belonging to 10 orders, 26 families and 54 genera. The most dominant fish order was Cypriniformes contributing 28 species in 16 genera. Cyprinidae was most dominant family contributing 23 species in 16 genera. Four alien species were found. Twenty eight species have been considered threatened by IUCN Bangladesh. These fishes were belonging to the following categories, Vulnerable (13%), Endangered (18%) and Critically Endangered (8%). Comparing the results with the previous findings, it was revealed that the species diversity have declined in the Padma River over time. Considering all the findings it is concluded that the Padma River could be considered a refuge for conservation of threatened freshwater fishes of Bangladesh. The conservation efforts should ensure minimization of anthropogenic impacts, especially the fishing pressure and introduction of alien invasive species.

Fish availability and market channel in Rajbari, Bangladesh

“…The sources of freshwater capture fisheries in Rajbari are mostly the River Padma, Gorai-the tributary of the Padma, vast floodplain areas during the rainy season and culture ponds ( BBS, 2011 ; Nadia et al., 2021 ). Joadder et al. (2015) and Hanif et al.…”

“…The sources of freshwater capture fisheries in Rajbari are mostly the River Padma, Gorai-the tributary of the Padma, vast floodplain areas during the rainy season and culture ponds (BBS, 2011;Nadia et al, 2021). Joadder et al (2015) and Hanif et al (2016) reported that, the biodiversity of fishes in the Padma River and the Gorai River is high including small indigenous fish species, Indian major carps, catfishes and so on. Consequently, the number of available species also outnumbered other previous studies on fish markets in different regions of Bangladesh (Roy et al, 2020a;Rahman and Islam, 2020).…”

“…(2011) , who identified 45 finfish species from the Bakkhali estuary, and Rahman et al. (2017) who identified 47 species from the Agunmukha river, Galib (2015) found 67 finfish species from Brahmaputra river, Joadder et al. (2015) documented 71 species from river Padma, Rahman et al.…”

Icthyofaunal Diversity of the River Padma at Murshidabad, West Bengal

“…Fish specimens were gathered, maintained and identified using morphometric and meristic characteristics. The specimens were set aside in flat plastic jars filled with a 10% buffered formalin solution (Joadder et al, 2015). According to Talwar and Jhingran (1991) and Rahman (2005), the specimens were identified using morphometric and meristic characteristics.…”
