“…The reason for the minimum level of DO in these months was increased demand for DO in the fish farms, resulting from higher production rates and increased metabolism during the warm months in fish farms. In research conducted in northwestern Poland, the greatest increase of organic matter and nutrients in a river was reported at the time of effluent discharge from fish farms when the BOD 5 level increased from 8.9 to 18.3 mgO 2 /dm 3 [25]. Farmaki et al (2015) also highlighted the effect of aquaculture on increasing the level of phosphorus and nitrate in the receiving water resources [26].…”

Recent rapid growth of the aquaculture industry and the necessity to comply with environmental standards suggest the need for studies on the possible negative effects of this type of industry. One of the most devastating effects of aquaculture is water pollution caused by the discharge of untreated effluent from fish farms into aquatic ecosystems. Assessment of the pollutants requires an optimal design of a water monitoring network in a way to demonstrate changes in aquatic environments. Accordingly, the present study used multivariate statistical analysis to determine sampling frequency for optimal monitoring of the contaminants resulting from trout farms in the Haraz River in northern Iran. For this purpose, a total number of 17 physical and chemical water quality parameters were sampled monthly over a one-year period based on the instructions recommended in the standard method (2005) [1]. The results showed that changes in biochemical oxygen demand (BOD) during the warm months of summer were very high and reached its peak in August and September. This may be attributed to the increased fish production in fish farms, increased food intake to feed the fish, and higher rate of discharge from fish farms containing waste feed and fish faeces. The nitrate also reached its maximum level in June due to the same reasons. Conversely, dissolved oxygen (DO) level was the lowest in the warm months (August and September). The reason would be increased consumption of DO due to higher production rate in the fish farms and increased metabolism of fish in warm months. Overall, the findings confirmed the applicability of multivariate techniques in

“…Aquaculture may have significant impacts on the environment and natural resources, and a number of concerns have been expressed by environmental activists and scientists [ 33 , 34 ]. Raczyńska et al [ 35 ] reported that little attention is paid to the changes in water quality resulting from the inflow of effluent discharged from fish breeding ponds. They, however, report that the aquaculture effluent discharge from the carp breeding ponds had a significant impact on the physicochemical parameters of the river water.…”

“…They, however, report that the aquaculture effluent discharge from the carp breeding ponds had a significant impact on the physicochemical parameters of the river water. They observed an increase in concentrations of the organic and biogenic compounds immediately after the inflow of the polluted water from the ponds [ 35 ]. However, more studies are needed in order to understand the decrease in fish biodiversity observed at station 2.…”

BackgroundNowadays, aquatic organisms are used as bio-indicators to assess ecological water quality in western regions, but have hardly been used in an Iranian context. We, therefore, evaluated the suitability of several indices to assess the water quality for an Iranian case study.MethodsMeasured data on biotic (fish and macroinvertebrates) and abiotic elements (28 physicochemical and habitat parameters), were used to calculate six indices for assessment of water quality and the impact of human activities in the Tajan river, Iran. GIS, uni- and multivariate statistics were used to assess the correlations between biological and environmental endpoints.ResultsThe results showed that ecological condition and water quality were reduced from up- to downstream. The reduced water quality was revealed by the biotic indices better than the abiotic ones which were linked to a variety of ecological water quality scales.ConclusionThe fish index showed a strong relationship with long-term database of physicochemical parameters (12 years (94%)), whereas macroinvertebrates index is more correlated with short-term data (76%). Meanwhile, the biotic and abiotic elements in this study were also classified well by PCA. Pulp and wood plants and sand mining are indicated to have the most negative effects on the river ecosystem.

“…Both, extensive and semi-intensive management systems, are typical for European carp ponds aquaculture [13,14]. Aquaculture pond effluents rich in nutrients pose a threat to natural aquatic ecosystems causing eutrophication [15][16][17]. Moreover, intensive aquaculture is a source of other dangerous effluents such as medications, disinfectants and antifoulants.…”

“…The ponds are connected with canals through sluices that allow water level control in the ponds [22]. Hydrological connection of a fish farm and adjacent surface waters directly affect mutual relationships of natural and artificial ecosystems (pollutants that can cause eutrophication, breeding species, invasive species, parasites and diseases, chemicals used in aquaculture) [13,14,16,18,23].…”
