“…The moisture content of prepared diets ranged between 9.43% and 9.90%, ash from 7.30% to 7.52% and NFE from 33.52% to 34.23%. The proximate composition of prepared diets was similar to those reports earlier made by Ashouri, Keyvanshokooh, Salati, Johari, and Zanoosi (), Baidya and Murthy (), Iqbal et al (), Monteiro, Rantin, and Kalinin (), and Zhou et al ().…”

The present study was conducted to evaluate the …effect of dietary selenium on growth performance and antioxidant enzymes activity in Cirrhinus mrigala for a period of 45 days. Four numbers of experimental diets were prepared, T c for Control (0 mg organic selenium/kg of diet), T 1 (2.5 mg organic selenium/kg of diet), T 2 (5.0 mg organic selenium/kg of diet) and T 3 (10 mg organic selenium/kg of diet). The water quality parameters (temperature, DO, pH, conductivity, hardness, ammonia, nitrate and nitrite) were found to be insignificant (p > .05) among all the treatments. Superoxidase dismutase (SOD) was found to be significantly highest in T 2 (6.10 ± 0.07) when compared with the other treatments. Similarly, catalase (CAT) activity in T 1 (13.21 ± 0.13) was significantly (p < .05) different with that of Control, T 2 and T 3 . Present study also revealed that 2.5mg organic selenium/kg supplemented diet (T 1 ) showed highest results in net weight gain (15.55 ± 1.36 g), net weight gain percentage (185.88 ± 8.98%) and SGR (2.35 ± 0.06 g) compared with other experimental diet.

“…If the N:P mass ratio is >17 it indicates P-limitation and N:P mass ratios <4 show N-limitation, whereas N:P mass ratios <4 and >17 indicate N, P co-limitation [41,42,49]. Water quality plays decisive role in defining the physical activities, survival and ambient life of fish species in aquatic ecosystems [22,31,[50][51][52][53]. The water quality parameters such as BOD, TP, N:P mass ratios, and CHL-a are studied to see how they affect the fish assemblages in rivers and streams.…”

Biological health assessment (BHA) has developed as an imperative gauge in efficient management of freshwater resources and fish assemblages. The principal objective of this research is directed at the development and application of a new index under the umbrella of the famous index of biological integrity (IBI). Further, we intended to carry out comparative assessments of the new index with two existing indices and testified to their rational in Geum River watershed, which is the third largest river water basin in South Korea. We analyzed the biotic integrity of 149 different study sites in the streams and rivers of Geum River watershed, perusing fish assemblages and water quality data. The results revealed the newer index, i.e., multi-metric (mm) IBI 06 (mmIBI 06 metrics), as comparatively more efficient than previously used indices, i.e., mmIBI 08 and mmIBI 11. Furthermore, the linear regression and correlational analyses indicated harmonic relation of mmIBI 06 with mmIBI 08 (R2 = 0.85) and mmIBI 11 (R2 = 0.87). Nonetheless, linear regression modeling discovered a very strong positive relation between mmIBI 08 and mmIBI 11 (R2 = 0.91), thereby implying previously used indices demonstrate better approximation. In significant contrast to both old indices, the newer index exhibited improved facility to better classify the study sites between the assortments of ‘excellent to very poor’ compared to old indices elucidated one-step lower, i.e., from ‘excellent to poor’. For instance, the newer index categorized 60 sites as ‘very poor’, requiring immediate attention owing to biological degradation. Additionally, the newer index endures grander ability to indicate sites requiring immediate management or restoration attention with a plausible site classification, especially in relation to the invasive alien species (IAS). The water chemistry was mainly influenced by rampant anthropogenic actions compounded by intensive monsoon precipitation that may relinquish highly suitable grounds for invasive alien fish species. This may eventually lead to severe biological degradation and successive deterioration of habitat by the IAS. In conclusion, the newer index endures ample capacity to indicate the fish community disturbances in rivers and streams. Further, correlation, linear regression, as well as principal component analysis (PCA) analyses on biotic indices and water chemistry showed higher approximations. Therefore, our newer index would be a valuable BHA tool to classify and elucidate the streams and rivers by indicating sites necessitating preferred attention and restoration measures.

“…Adams [40] pointed out that the combination of comet assay and physiological assays using fish samples (sentinel species) plays a significant role in risk assessments of aquatic ecosystems. They may act as very effective biomarkers used in detecting the organic matter, toxic chemicals, and heavy metal pollution [41][42][43][44] in urban streams. Moreover, the comet assay is known as a biomarker that is considered one of the best barometers used in assessing DNA damage by oxidative stress responses [12,45].…”

Ecological risk assessment was carried out in two urban streams, viz. Gap Stream (GS) and Miho Stream (MS), in the Geum River Watershed during July 2013-October 2014. The techniques used in this study included multi-level fish biomarkers of DNA damage based on single-cell gel electrophoresis (SCGE) coupled with the study of physiological responses based on 7-ethoxyresorufin-O-deethylase (EROD) and acetylcholinesterase (AChE) activities in fish species. Biomarker values of tail DNA (tDNA), tail length (T L), and tail extent moment (TEM) in impacted zone (I z) were 2.0-3.6-fold greater than in controls (C z). Nucleus image analysis showed that the nucleus had circular particle forms in the C z as compared with a longitudinal oval form with broken particles from the nucleus in the I z. Physiological response analysis of EROD and AchE activities indicated that their levels were higher in the I z than in the C z. Such DNA damages and greater physiological responses in the I z were attributed to chemical contaminants discharged from the wastewater disposal plants and industrial complex. This combination of DNA damage and physiological responses approach can be used as a key tool for early-warning detection of chemical contaminants and concomitant risks to the ecological health of urban streams.
