“…The muscle tissue was always contained a significantly lower Zn than the other tissues (P \ 0.05). This is consistent with Ortiz et al (1999), Senthil Murugan et al (2008, and Palaniappan et al (2010) who reported similar trends in the Sole Senegalenis, Channa punctatus, and rohita carp, respectively.…”

“…Moreover, the loss of protein and lipid levels in the Zn-exposed fish may be due to increased protein oxidation with Zn exposure (Cakmak et al 2006). Palaniappan et al (2010) reported that Zn exposure caused important structural alteration in the existing proteins indicated by a significant reduction in the intensities of the a-helix. They also suggested that Zn exposure causes significant alteration in the protein secondary structure by decreasing the a-helix and increasing the b-sheet content of the gill tissues of rohita carp, Labeo rohita.…”

“…In addition to being a source of protein to humans, they play important roles as bioindicators of trace element pollution (Rashed 2001). For this reason, the utility of fish for assessing environmental conditions in aquatic ecosystems has gained prominence in recent years (Yilmaz 2003;Budambula and Mwachiro 2006;Adeniyi et al 2008;Palaniappan et al 2010). Due to the deleterious effects of Zn on aquatic ecosystems, it is necessary to monitor its potential impact on fish performance and health.…”

The present study was carried out to investigate the effect of sublethal zinc (Zn) concentrations on growth performance, biochemical variables, and Zn residues in various organs of Nile tilapia, Oreochromis niloticus (L.). Fish (25 ± 0.5 g) were exposed to 0.0, 3.5, or 7.0 mg Zn L -1 for 1 or 6 weeks. Fish growth was significantly reduced with increasing Zn concentrations. However, fish exposed to 7.0 mg Zn L -1 grew less quickly than those of the control group. Likewise, best feed intake and feed conversion ratio were obtained at the control group. Furthermore, glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, and cortisol increased significantly with increasing Zn concentrations and exposure time, with maximal values in the 7.0 mg Zn L -1 treatment after 6 weeks. Meanwhile, highest values of serum protein and lipids were obtained in the control fish reared for 6 week, whereas their lowest values were observed in fish exposed to 7.0 mg Zn L -1 for 1 week. There was no significant change in whole-body moisture content of fish due to Zn exposure, although crude protein and total lipid contents decreased significantly with increasing Zn concentrations. In addition, Zn exposure increased total ash contents and Zn residues in different investigated fish organs. The Zn concentrations in all fish organs were time-dependant and the Zn residues after 1 week were found to follow the order of gills [ liver [ kidney [ muscle, meanwhile after 6 weeks it followed the order of liver [ kidney [ gill [ muscle. The present findings revealed that liver and kidney tissues are the prime sites of Zn bioaccumulation, while Zn load in the muscle was for low as compared to other organs.

“…Mastan [21] has also been reported the similar pattern of bioaccumulation in Labeo rohita . Experimental studies have shown that muscles of Labeo rohita accumulate least metal zinc as compared to other organs [33]. Bioaccumulation of heavy metals like mercury, chromium, and nickel has been documented to be influenced by variation in age, season, and gender and this may correlate with feeding habits in different seasons and areas [34–36].…”

We examined and compared heavy metals bioaccumulation in Cyprinus carpio and Labeo rohita netted from Sardaryab, a tributary of River Kabul. By using atomic absorption spectrometry we assessed different organs including livers, gills, and muscles. Metals studied were chromium, iron, zinc, lead, and copper. Livers of both species showed higher concentrations of metals while muscles showed the least amount. Chromium and iron were the highly concentrated metals in the gills and livers of both species. A quantity of 0.154 ± 0.011, 0.199 ± 0.0079, and 0.024 ± 0.008 μg/g of chromium was found in the gills, livers, and muscles of Cyprinus carpio, respectively. Similarly, the gills, liver, and muscles of Labeo rohita contained 0.133 ± 0.008, 0.165 ± 0.01, and 0.019 ± 0.006 μg/g of Cr, respectively. Iron was highest in carp in the range of 0.086 ± 0.01 in gills and 0.067 ± 0.011 μg/g in muscles, comparatively. All the studied metals were found within the US recommended daily dietary allowances (RDA) limits; hence no immediate risk in their consumption for human was found. The data showed that Cyprinus carpio being omnivorous and bottom feeder stored higher concentrations of metals as compared to Labeo rohita.

“…This observed reduction may be due to pathological alterations in liver and kidney tissues as a result of the toxicant stress (Lavanya et al 2011;Nwani et al 2013). The decrease may also be due to the fact that fertiliser exposure causes significant alteration in the protein secondary structure which, according to Palaniappan et al (2010), results in decreasing the -helix and increasing the -sheet content of the gill tissues of Labeo rohita exposed to zinc.…”

The indiscriminate use of inorganic fertilisers to boost plant productivity has resulted in negative consequences in aquatic ecosystems. The effects of chronic exposure to NPK (15:15:15) fertiliser at 0.40, 0.80 and 1.60 g l −1 on the haematological and biochemical responses of Clarias gariepinus were determined under a static renewal bioassay for a period of 56 days in April-June 2013. There was a reduction in haemoglobin levels, mean corpuscular haemoglobin and haematocrit, while mean corpuscular haemoglobin concentration increased in exposed fish compared to the control. There was a significant difference (p < 0.05) between the levels of the parameters examined in exposed fish and the control. However, a mixed trend was observed in the leucocyte differentials. In addition, glucose, alanine aminotransferase and aspartate aminotransferase levels were significantly increased while protein levels were reduced (p < 0.05) in the plasma throughout the exposure period. Prolonged exposure of C. gariepinus juveniles to NPK can lead to physiological dysfunction in the fish.
