“…However, there are other studies that contradict the hypothesis that sediment accumulation reducing oxygen availability relates to production of smaller fry. Argent and Flebbe (1999), reported little changes in brook trout fry length; rather they reported a general decline in fry mass with increasing fines. Fudge et al (2008) observed that the temporal pattern of rainbow trout emergence in the laboratory was affected by increased sediment loads.…”

Abstract:Increased sedimentation in surface waters due to anthropogenic activities can lead to the deterioration of salmonid spawning habitat through infiltration of excessive fine sediment into redds. This study assessed the effects of sediment on salmonid reproductive habitat on Prince Edward Island, Canada by evaluating egg survival and fry length using brook trout egg in situ incubations. In-stream egg incubators were buried in the substrate of streams in three watersheds with between 10 and 69% agricultural land-use during 2012-2013 and 2013-2014. Accumulated incubator sediment load and associated particle size, incubator organic matter and stream parameters temperature, velocity, bed sediment and particle size were measured over the period of study. There was no significant difference in embryo survival among watersheds. Survival was not related to fine sediment; instead, it increased with higher average temperature that was in turn associated with the presence of groundwater upwelling in the stream. The size of the fry was also not significantly different between watersheds with varying agricultural activity. Fry length was most strongly related to sediment organic matter content. Brook trout are widespread in PEI rivers, including in many rivers that have high sediment loads due to intensive agricultural land use. This species may avoid the adverse effect of fine sediment through their natural adaptation of using groundwater upwelling for spawning. Sedimentation is of particular concern on PEI because of its potential to impact spawning habitat for native salmonids, namely brook trout and Atlantic salmon (Merz et al., 2004;Curry and MacNeill, 2004). While brook trout remain widespread on PEI, Atlantic salmon is only present in about one third of its former rivers (Cairns and MacFarlane, 2015) and its decline has been attributed to a variety of factors, including excessive sedimentation (Guignion et al., 2010). In contrast to the situation on PEI, there is evidence of the decline of brook trout in other parts of the world that has been attributed to landscape alteration (Stranko et al., 2008). Thus, the study of the impacts of sedimentation on brook trout spawning can provide some insight into the persistence of this species on PEI despite the seemingly adverse conditions. The objective of this study was to assess the effects of deposited sediment on brook trout survivorship and fry length on PEI. This study tested the hypothesis that sediment is a limiting factor in salmonid egg survival to hatching and emergence. Survival was assessed by placing in-stream egg incubators in three watersheds with varying degrees of agricultural land-use during two separate spawning seasons. Eggs were monitored for hatching and swimup over the early spring months and the relationship between survival and fine sediment accumulated within the incubators was assessed.

“…This is especially true for substrate spawners (Muncy et al, 1979). If sedimentation occurs after spawning, then oxygen supply to eggs and sac fry in the substrata may be decreased due to reductions in water circulation (Waters, 1995;Argent and Flebbe, 1999). Consequently, sedimentation decreases available spawning habitat, reduces spawning activity, and increases egg and larvae mortality (Alabaster and Lloyd, 1982;Ryan, 1991).…”

Abstf'~ct: Sedimentation and turbidity are significant contributors to declines in populations of North American aquatic organisms. Impacts to lotic fauna may be expressed through pervasive alterations in local food chains beginning at the primary trophic level. Decreases in primary production are associated with increases in sedimentation and turbidity and produce negative cascading effects through depleted food availability to zooplankton, insects, freshwater mollusks, and fish. Direct effects at each trophic level are mortality, reduced physiological function, and avoidance; however, decreases in available food at trophic levels also result in depressed rates of growth, reproduction, and recruitment. Impacts of turbidity to aquatic organisms often seem inconsistent among watersheds and experiments, but this apparent difference is actually due to the lack of correlation between suspended sediment concentrations (mg/L) and units of measure (Nephelometric Turbidity Units, NTU). The use of NTU as a surrogate measurement of suspended sediment to predict biotic effects within watersheds is dubious. Similar NTU measurements from different watersheds may be correlated with different concentrations of suspended sediment. For monitoring the effects of turbidity within local watersheds, we recommend that the correlation between suspended sediment and NTUs be examined over a range of discharge recordings, and that this be used as a baseline to examine local effects. We recommend that riparian buffer strips and livestock fencing be used to reduce sediment input to streams.

Remote sensing and geographic information systems (GIS) play a key role in all geospatial aspects of the assessment and management of water resources for inland fisheries and aquaculture. Lake, wetland, and reservoirs are some of the important inland water resources for potential fish production and help improve the rural economy on large scale. Fisheries development perspective reservoirs of the Tarai region are Naitaal, Tumaria, Haripura, Baur, Baigul, Dhaura, Nanaksagar, and Sardasagar, which are located at 28°25 0 -29°55 0 N latitude and 78°18 0 -79°55 0 E longitude. Waterresource assessment such as spread area, water quality, nutrient analysis, chlorophyll content, and other physico-chemica properties may be done through the mapping. Hence, remote sensing and GIS software and images like Landsat-ETM?, Landsat-8 and other multi spectral images utilization at short time frame for potential fishing zone identification, rate of sedimentation, geomorphological changes such as land cover, erosion and accretion in reservoirs as well. Thus it will help in decision making and blueprint preparation for sustainable water resource management at a cost-effective rate. The current review emphasizes the potential of high-resolution satellite images for mapping and analysis of water resources at Tarai region of Uttarakhand.
