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 (<i>p</i> &lt; 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 (<i>r</i> = 0.238, <i>p</i> = 0.035). The reservoir water storage level was positively correlated (<i>r</i> = 0.621, <i>p</i> &lt; 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.</p>","PeriodicalId":54928,"journal":{"name":"International Review of Hydrobiology","volume":"106 5-6","pages":"259-276"},"PeriodicalIF":1.9,"publicationDate":"2021-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/iroh.202102093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43667636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, they have been heavily modified by land use, technical flood protection measures, and hydropower installations. Fish species requiring specific habitats to complete their life cycle have strongly declined and therefore become target species of river restoration measures. This study compared abiotic conditions and fish community composition of three bank habitat types in a large alpine river, comprising different degrees of alteration compared to the natural state (concrete profile, bank riprap, and naturally restored riverbank). Significant differences in abiotic habitat characteristics such as bed material, water depth, turbidity, submerged vegetation, and temperature were detected between the three bank habitat types and sampling seasons. These water level-dependent structural changes had the strongest effect on fish community composition as detected by distance-based linear modeling. Small specimens between 3 and 13 cm TL and juveniles were most abundant in the restored areas, except for <i>Lota lota</i>, which was most abundant in the man-made bank riprap. Target species of conservation were mostly detected in restored areas, particularly the critical young life stages of <i>Chondrostoma nasus</i>, <i>Barbus barbus</i>, and <i>Thymallus thymallus</i>. Water level strongly determined accessibility and suitability of bank habitats, with shallow, gravel-dominated habitats comprising flat bank angles being most beneficial for these species. The findings of this study provide evidence for the success of bank habitat restoration in structurally impacted alpine rivers on target species of conservation. Fluctuating water levels and discharges typical for alpine rivers should be better considered in restoration planning, particularly in light of climate change, affecting the timing and amplitude of discharge in these systems.</p>","PeriodicalId":54928,"journal":{"name":"International Review of Hydrobiology","volume":"107 1-2","pages":"46-59"},"PeriodicalIF":1.9,"publicationDate":"2021-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/iroh.202002079","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48965235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We tested for seasonal patterns in the metacommunity assembly mechanisms of macroinvertebrates in small subtropical highland wetlands of southern Brazil with different hydroperiods. We also tested whether patterns varied between macroinvertebrate taxa with different dispersal modes. Macroinvertebrates were sampled in 12 wetlands classified into “short,” “medium,” and “long” hydroperiods (<i>N</i> = 4 in each category) in three seasons (fall, winter, and spring) over two full hydrological cycles (from 2012 to 2014). We assessed the role of spatial and environmental variables to metacommunity structure using distance-based redundancy analysis and variation partitioning. Environmental and spatial variables explained macroinvertebrate metacommunity structure, although their relative influence markedly changed among seasons and hydroperiods. Environmental variables were important in fall and winter, whereas spatial variables predominated in spring. Different environmental variables influenced the metacommunity structure in each hydroperiod. Environmental variables influenced active-dispersing macroinvertebrates, whereas the influence of environmental and spatial variables on passive-dispersing taxa changed among seasons. We showed that the assembly mechanisms of macroinvertebrate metacommunities show a distinct temporal dynamic among wetlands with different hydroperiods.

Thus, floodplains are a key to improving river water quality. Yet, the factors that determine the amount of fine sediment that deposits on floodplains are largely unknown. Plant diversity typically increases structural diversity, whereas the vegetation structure and the structural characteristics of individual species are known to influence sedimentation. We hypothesised that species diversity, in addition to species identity, may promote sediment retention. Our study aimed to disentangle the effects of species richness and species identity, via differences in vegetation structure, on sediment retention within herbaceous vegetation patches. In a flume experiment, we investigated sedimentation on 30 vegetation patches (40 × 60 cm²). We created patches with five different species-richness levels (3, 4, 6, 8, and 11 species), each replicated six times. Species were randomly selected from 14 common floodplain species. We inundated the patches with silt- and clay-rich water and measured the amount of accumulated sediment on the vegetation and on the ground underneath it. Species richness significantly increased sedimentation underneath the vegetation (<i>R</i>² = 0.17). However, including species identity effects in a structural equation model, we showed that individual species' presence largely drove these effects. <i>Alopecurus pratensis</i> had a direct negative effect on sedimentation on the vegetation, whereas <i>Bromus inermis</i> and <i>Elymus repens</i> had indirect positive effects through an increase in total biomass (<i>R</i>² = 0.42). <i>Elymus repens</i> had a direct negative, and <i>Urtica dioica</i> a direct positive effect on sedimentation underneath the vegetation (<i>R</i>² = 0.38). Our results indicate that selecting the most effective species, rather than as many species as possible, may have the greatest benefits for promoting sedimentation.
