Fisheries ecology of the northeastern Himalayas with special reference to the Brahmaputra River
Ecological Engineering, 2000
The northeastern Himalayan region is identified as one of the richest regions of the world in bio-diversity. Being in a heavy rainfall zone and also blessed with innumerable snowfed streams and rivers, the region is well-known for fish diversity especially for ornamental fish. The hill streams have poor but distinctive fish fauna, while the floodplain rivers of the region harbour over two hundred species of fish and other aquatic fauna, including the endangered freshwater dolphin, Platanista gangetica. The beels, or the floodplain lakes, are ideal habitats for air-breathing fish and they also act as feeding and breeding grounds for riverine fish during monsoon months. The present communication highlights the hydrobiological features and the ichthyofauna of certain selected water bodies of the northeastern Himalayas with special reference to the Brahmaputra River. : S 0 9 2 5 -8 5 7 4 ( 0 0 ) 0 0 0 7 5 -6

Fishes are the most diversified group among vertebrates, with ca. 33,600 species [3] characterized by their great diversity in morphology, physiology, ecology, life history and behavior. Almost 25% of the global vertebrate diversity accounted by fish is concentrated in the 0.01% of the earth’s water. This tiny fraction of earth’s water supports at least 100000 species out of approximately 1.8 million and almost 6% of all are described species [4]. It is often claimed that freshwater ecosystems arethe most endangered ecosystems in the world [5]. This particular vulnerability of freshwater to fish at global scale reflects the fact that both fishand freshwater are the need of humans and consequently they have been heavily impacted by theiruse and regulation. Asia supports over half of the global human population, with enormous consequent pressures on inland waters and freshwater fish biodiversity [4]. The freshwaters in India are one of the most exploited resources since past many year...
Scope of ornamental fisheries in snow fed rivers of Uttarakhand - Overview
Journal of Applied and Natural Science, 2015
Upland rivers of hills of Uttarakhand are unique in its ecosystem and biodiversity. These waters possess various varieties of ornamental fishes. The present study focuses on Scope of ornamental fisheries in snow fed rivers of Uttarakhand, along with challenges and opportunities. Besides the availability of resources peoples are not that much aware of ornamental fisheries of this region and these resources are yet not developed. The use of destructive fishing methods, habitat destruction leads to diversity destruction of hills stream fishes. As these resources does not comprise fisheries of commercial importance due to sparse biota and low thermal scale, slow growth and very low natural food availability So, Directorate of Cold Water Fisheries is actively working in the field of survey and brood stock management of ornamental fish resources of cold water. Four hundred live cold water fishes including exotic gold and koi carp are being maintained at DCFR main complex for study and breeding trials. The recreational activities by fisheries department like ranching, sport fisheries development and development of ornamental fisheries of this region can lead to socioeconomic upliftment of hilly people and development of cold water ornamental fisheries in the state.
A Survey on Fish Population Availability in Different Season in Northern India

Some of the studies indicated that Himachal Pradesh has the great potency for the trout fi shing (Oncorhynchus mykiss, Salmo trutta fario, Schizothorax richardsonii, Schizothorax richardsonii) near the various stints of Beas, Satluj, and Ravi River. This region is also characterized with the presence of Mahseer, Carps and Hill stream fi shes [8]. The Punjab, another state in northern India, has different types of fi shes like Clarias batrachus, Wallago attu, Mystus cavasius, M. bleekeri,
Fish fauna of Uttarakhand, India: Present status, Diversity and Conservation
Journal of Mountain Research
Extensive Ichthyofaunal survey of various water resources of Uttarkhand was carried out for the period of more than 15 years (2004-2019). The main objective of this paper is to know the district wise status, distribution and to recommend the strategy for the conservation and management of fishes of the state, so that clear-cut idea could be drawn, for further research and policy planning. In the present paper a total of 132 species of fish belonging to 67 genera, 27 families and 8 orders have been reported. The district wise distribution of fish represented a maximum of 101 species from Nainital, followed by 81 species from Dehradun, 75 species from Haridwar, 73 species from Udham Singh Nagar, 59 species from Pauri Garhwal, 37 species from Rudrapryag, 36 species from Almora, 35 species from Chamoli, 34 species from Bageshwar, while 32 species from Pithoragarh and Champawat and 29 species each from Uttarkashi and Tehri Garhwal. Besides these 10 species (7.5%) are in the category of E...

The present study was conducted in the Eastern Himalayan region to generate a primary database on ichthyofauna diversity of seven rivers in three districts (Cooch Behar, Jalpaiguri and Alipurduar) of West Bengal, India. Out of the seven rivers, five rivers originate from Bhutan ghat hills, and the other two rivers the Teesta, originates from North Sikkim and river Karala from Jalpaiguri. 141 indigenous fish species belonging to 31 families were identified. The family Cyprinidae represented the largest diversity accommodating 21 genera and 46 species. Amongst all the fishes, 99 species have ornamental value and 87 species the food value. Ornamental fishes are dominant over the food fishes and carnivorous fishes are dominant over the omnivorous and herbivorous fishes. According to IUCN (International Union for Conservation of Nature ) and CAMP (Conservation Assessment and Management Plan), the conservation status of the fishes are listed as 1 (1%) species as Critically Endangered, 12 ...

A survey of published literature on fish distribution in India reveals the occurrence on 363 native species from 122 genera, 36 families and 11 orders in the highlands of India, Nepal and Bhutan. The Himalayan region harbours the largest number of species (266), genera , families (32) and orders (11). In Western Ghats (WG), 155 species, 62 genera, 24 families and 10 orders occur compared with 95 species from 55 genera, 22 families and 8 orders in the Central Highlands (CH). Species:family ratio is lower in CH (4.3) than in WG (6.5) and the Himalaya (8.3) indicating greater diversity at family rather than species level. Further, a sizeable number of species occur within one family, the Cyprinidae, suggesting recent richness with respect to species, especially in the Himalaya. Only 41 species were common to the three highlands. A large number of species are restricted in distribution (164 in Himalaya, 77 in WG and 8 in CH).
