Anthropogenic pollution by trace metals in aquatic environments in semiarid zones is a critical area of investigation. The objective of this study was to investigate the concentration and spatial distribution of trace metals in surface sediments in the Rosário reservoir, which is affected by the intensive aquaculture of Tilápia-do-Nilo (Oreochromis niloticus). Sediment samples were collected in three different areas, postculture (PCTV), cultivation (CTV) and control (CTRL) in the dry season in 2019. The granulometric composition, organic matter and concentrations of Fe, Mn, Zn, Cu, Cr, Cd, Pb and Ni metals were determined. Multivariate statistics were used. Geochemical and ecotoxicological indices and a comparison with sediment quality guidelines (SQG) were used. The sediment was characterized by silty clay loam with an average organic matter of 18.76 ± 4.27. The analytical merit figures demonstrated accuracy (metal recoveries in certified standards) between 89 to 99% and high precision (RSD < 5%). The concentration ranges for the metals were Fe: 0.11–0.85 (%), Mn: 14.46–86.91, Zn: 2.6–220.56, Cu: 26.89–98.75, Cr: 60.18–76.06, Cd: 0.38–0.59, Pb: 18.13–43.13, and Ni: 34.4–46.75, all in (mg/kg−1). The highest concentration values were found in the CTV areas (Fe: 40 ± 0.22, Mn: 66.48 ± 19.11, Zn: 114.83 ± 59.75 and Cr: 70.85 ± 2.62) and PCTV (Cd: 0.53 ±0.04, Cu: 71.83 ± 21.20, Pb: 33.71 ± 4.34 and Ni: 44.60 ± 1.79). Pearson’s correlation, hierarchical cluster analysis and principal component analysis confirmed the influence of fish farming on metals. Only Ni presented concentration values higher than the reference value established in the SQG. Thus, considering the probable geochemical and ecotoxicological effects, they comprise the two lowest levels of impact.

“…However, high investment and slow growth are major challenges. Cage culture of rainbow trout is practiced widely in many other countries [11][12][13][14][15] There are several advantages of cage culture as it allows complete harvesting in the spring when the water temperature rises above their tolerance limits [7,16] .…”

Rainbow trout (Oncorhynchus mykiss) is getting priority in aquaculture in Nepal. However, high investments, slow growth in land-based/raceway systems are major challenges. Country would be benefited, if lakes/reservoirs could be utilized for its cage culture. A preliminary trial was conducted in a shallow-reservoir created for hydropower installing three cages, 6 m × 4 m × 2 m size to evaluate its growth and production potential. The trout juveniles of 57.6±15.4 g (average weightSD) were stocked and fed with 33% crude protein diet twice daily at maximum 3% of body weight for 91-days. A random sample of 50 fish per cage was measured total length and body weight each month. Results showed that it is possible to achieve high survival (96.61.7%) with reasonable growth rate (0.80 g.fish -1 ) and productivity (8927 kg.cage -1 ) with fair condition factor (1.20.1) when stocked 10-20 fish.m -3 . These parameters implied that farming of rainbow trout in the shallow reservoir could be successfully done during winter-spring season in a year. However, further research is needed with stocking densities, feeds and feeding rates/methods, and also conducting longer period which may further enhance the productivity thereby profitability.
