“…The lack of comprehensive historical data makes it di cult to estimate the temporal changes in ecology (Sarkar et al 2018). Lack of scienti c knowledge base on auto recruitment, migratory patterns and site delity of shes, and complex food web dynamics in large reservoirs is still a challenge (Lianthuamluaia et al 2019;Sandhya et al 2019).…”

The geographic information systems (GIS) play an important role in all geospatial aspects of assessment, monitoring and management of inland open water resources for strategic development in fisheries sector. In India, reservoir fisheries development is one of the flagship programme and several initiatives have been taken up towards enhancement and sustainable development. The present study investigates spatio-temporal changes in ecology and fisheries in Hirakud reservoir, Odisha build across river Mahanadi which features one of the largest dam in South Asia. The reservoir is mainly utilized for electricity generation, irrigation and offers tremendous scope to support fisheries and livelihood. As per the seasonal variation analysis, water spread area was at the minimum during premonsoon period. Most of the water quality parameters including nitrate, phosphate, BOD and alkalinity were higher in the premonsoon period and overall the parameters were under favourable range for fisheries. The present investigation from the fish landing sites of the reservoir, recorded merely 40 fish species, indicating loss of fish diversity as compared to the historical reports. The IUCN conservation status showed that among the 40 species only one species, Wallago attu is under VU category and 4 species Chitala chitala, Ompok bimaculatus, Ailia colia and Bagarius bagarius are under NT category. The analysis of time series annual fish catch data using ARIMA model forecasted the increasing trend of fish production. The water quality parameters were presented in GIS platform for better understanding of the spatial variations over time. Habitat protection of fish breeding grounds, closed seasons, mesh size regulations, scientific management and community participation are recommended as the measures for conservation of fish diversity and sustainable enhancement of fish production in the reservoir.

“…However, the scatter plots of the fish yield and F I G U R E 6 Relationship between fish yield and area of reservoir stocking density showed a weak positive trend while and a weak negative trend was found between area and fish yield. Stocking density plays an important role in fish yield, but other factors like the exploitation pattern of the fish stock, seed quality and species composition, native fish diversity composition and ecological status are also important drivers of fish yield (Kumari et al, 2018;Lianthuamluaia et al, 2019;Nguyen et al, 2005;Paul et al, 2017;Piska & Rao, 2005;Sarkar, Sandhya, et al, 2018;Sugunan & Katiha, 2004). However, a positive relationships between stocking density and fish yield (Nguyen et al, 2005;Phan & De Silva, 2000;Sugunan & Katiha, 2004) and an inverse relationship between area and fish yield (Amarasinghe, 1998;Fonticiella, Arboleya, & Diaz, 1995;Li & Xu, 1995) have been described elsewhere.…”

The present study investigates the success of stocking fingerlings of Indian major carps ‐Gibelion catla (Hamilton), Labeo rohita Hamilton and Cirrhinus mrigala Hamilton – to enhance fish yield in 58 small reservoirs in Odisha State, India. Fish stocking and yield data were collected from State Fisheries Department, Odisha. The relationships between area, stocking density and fish yield of different size groups of reservoirs were assessed using the Pearson correlation coefficient (r). Fish yield increased significantly (p < 0.05, t‐test) from 204 kg/ha/year in 2012–13 to 323 kg/ha/year in 2013–14 due to adoption of CBF. The corresponding per capita fish production increased from 398 kg fisher−1 year−1 to 702 kg fisher−1 year−1 benefitting more than 8,000 fisher households. Reservoirs in the size group 100–500 ha showed the highest response of fish yield with respect to stocking of fingerlings. The size of fingerlings at stocking and area of the reservoir had greater impact on enhancing fish yield. Stocking had a profound positive impact on fish yield. This study forms a baseline evaluation of the impact of stocking on small tropical reservoirs in India. It also recommends management measures and discusses issues, and the way forward for sustainable fisheries enhancement in small tropical reservoirs in eastern India.

“…However, the studies on the impact assessment of fingerling stocking is inadequate although it occupies a major share in total large reservoir area of India. Such information is almost nil for large Indian reservoirs though a few researchers have reported fish assemblage pattern, diversity, and some biological aspects of fishes from large reservoirs (Kumari et al, 2018Lianthuamluaia et al, 2019;Sandhya et al, 2017Sandhya et al, , 2019.…”

Tropical reservoir ecosystems cover more than 3.51 million ha in India which are the major sources of fish production from inland open waters and supports rich diversity of fish. The present study quantifies fisheries enhancement and evaluates the impact of stocking of Indian major carp fingerlings in six large reservoir ecosystems of India. Analysis of time series data revealed a significant increase (p < 0.05) in fish yield from 12.3 kg ha −1 year −1 in 2004-2005 to 52.4 kg ha −1 year −1 in 2016-2017 due to stocking. The average fish yield of these six reservoirs was estimated to be higher than the national average of 33 kg ha −1 year −1 recorded for large Indian reservoirs. Fingerling stocking had a significant positive impact on fish yield (r = 0.238, p = 0.035). The reservoir water storage level was positively correlated (r = 0.621, p < 0.05) to fish production. The study also shows that the reservoir habitat support 99 finfish species in the central Indian reservoirs of which two species belong to endangered category warranting conservation efforts. This study is the first of its kind on assessing the impact of stocking in large number of tropical reservoirs including the largest reservoir in the country revealing positive effect on fish yield. The fish yield of 85.8 kg ha −1 year −1 obtained in Gandhisagar reservoir (72,300 ha), India revealed that fisheries enhancement is effective and remunerative. The study also highlights the global status of stocking impact in large reservoirs and deliberates issues and suggests management strategies for sustainable fisheries enhancement in large tropical reservoirs.
