“…C. carpio and Oreochromis niloticus have not follow any rule and regulation in respect of water quality [34][35][36]. The invasive fish species are a highly nonrandom subset of the freshwater biota [37][38]. The Ghaghara River is exposed to different anthropogenic stressors, including organic and nutrient pollution and contamination with priority and other chemical substances from agriculture and local industries.…”

Human activities have been widely accepted as a driver of rapid trait change in wild fish stock globally with help of stressors. Fishing and invasive species are among the most important stressors which are affecting freshwaters fish stock from the lotic and lentic ecosystem. Study was carried out between the periods November 2015 to October 2016 from the Ghaghara river at Faizabad, India. The age composition of C. mrigala varied from 0+ to 8+ from the Ghaghara river at Faizabad. On the basis of sampled specimen in the length range from 15.7 to 88.7cm showed that the fish attained the mean length 25.3cm in 1+, 43.8cm in 2+, 57.5cm in 3+, 67.2cm in 4+, 74.7cm in 5+, 79.6cm in 6+, 83.9cm in 7+ and 87.3cm in 8+ age classes. The growth increments of C. mrigala was recorded as 25.3cm, 18.5cm, 13.7cm, 9.7cm, 7.5cm, 4.9cm, 4.3cm and 3.4cm for 1+ to 8+ age classes, respectively. The maximum growth increment was estimated in 1 st year and moderate in the subsequent years.

“…In general, C. carpio and O. niloticus have not any ecological standard from the lotic ecosystem [5,[43][44][45].Both species are commercially exploited from the Ganga basin [46] and highly utilize natural resources, threat biodiversity of fishes and damage indigenous fish stock [47][48][49]. But reproductive system and recruitment process are damaging by high concentration of metals in fish body [50][51][52][53].…”

Cyprinus carpio (Common carp) and Oreochromis niloticus (Nile tilapia) are commercially and frequently exploited fishes from the Ganga river at Kanpur, India. Study was undertaken during the period 2012 to 2013 from the Ganga river. Rivers are heavily impacted due to their use for carrying off the industrial, municipal, agricultural and domestic effluents. Water samples were collected for the present study from the Ganga river at Kanpur. The minimum temperature was recorded in winter season and maximum in summer season. The pH, TDS, EC, phosphate, chloride, total hardness, nitrate, DO and all heavy metals (e.g. Cu, Cr, Cd, Zn, Pb, Hg) values exhibited their minimum in monsoon season. The sulphate and BOD were recorded minimum in winter season while alkalinity and COD had their lowest values in summer season. The water quality of the Kanpur station was very poor which is not suitable for Indian major carp (IMC). However, the Ganga river waters could host some tolerant fish species such as the exotic Cyprinus carpio and Oreochromis niloticus and also catfishes. All these species are very hardy, in respect of water quality (poor), thus they have strongly invaded in despoiled ecosystem of the river.

“…The most extensive river system in Asia is the Ganga riverine system and the region with the greatest variety of fish in India (Bilgrami et al, 1992). Additionally, a variety of other ecosystem services are provided by the Ganga River's fishery resources (Dwivedi et al, 2016; Dwivedi & Mayank, 2017; Pathak et al, 2014). The Ganga River is split into three regions: the upper region, the intermediate zone, and the lower region (Sarkar et al, 2012).…”

Status of fish assemblage structure in the Ganga and Indus riverine systems of the western Himalaya

et al. 2023

View full text Add to dashboard Cite

The Ganga and Indus riverine systems are the major freshwater resources in the western Himalaya. The aim of this review was to critically analyze the status of inland fisheries in both the Ganga and Indus Riverine systems of the western Himalaya. Data from secondary sources such as research publications, scientific documents, technical advisories, and books were retrieved. The fish diversity of both riverine systems reveals that the number of endemic and native species like Tor tor, Tor putitora, Glyptothorax spp., Nemacheilus spp., and Schizothorax richardsonii is decreasing. Moreover, in most of the rivers of both riverine systems, exotic species, especially those belonging to the Cyprinidae family, for example, Cyprinus carpio, are increasing and are also dominant, followed by the families Cobitidae and Sisoridae. The Ganga and Indus riverine systems' diverse fish populations have declined because of various anthropogenic activities, especially water pollution and dam construction, which are responsible for the change in river hydrology. Frequent data were available on the Ganga riverine system, which shows a continuous decline in fish diversity. A similar trend was observed in the lower stretches of the Indus riverine system. But negligible information was available on the upper stretches of the Indus riverine system; this may be due to a large research gap. However, adequate knowledge of both river systems is necessary to develop conservation and management strategies for the sustainable development of fishery resources in India in the future.
