“…Ali et al (2003) observed reduced growth of Oreochromis niloticus under different (0, 0.5, 0.3, & 0.5 ppm) water-borne Cu levels (Ali et al 2003). Also these results are in accordance with the findings of Mohanty et al (2009) that determined the effect of copper on survival, growth and feed intake of Indian major carp, C mrigala for 60 days.…”

The aim of present study was to determine the LC50/96 h value of copper sulfate and determine the growth performance of Caspian Sea kutum) Rutilus frisii kutum (fingerlings during 60-days sub-lethal copper (Cu). After acclimation period to two weeks, for determine the LC50/96 h value, total of 27 aquarium with a capacity of 60 L each stocked with 10 fishes an aquarium. Tunney four aquarium and 8 concentrations of (Cu) composed the 24 treatments while 3 other aquaria were used as control. For each treatment, three replications were conducted. And experiment to determine the growth performance fish were transferred into fiberglass aquaria of 200 L water capacity for growth trials. The treated fish were kept in the aquarium containing sub-lethal concentrations of Cu (0.11 and 0.23 mg L-1) and affected to grow for 60 days, while control fish were placed in metal free water. The results indicated that median lethal concentrations (LC50) of copper to Caspian Sea kutum for 96 h exposure was 2.310 ppm. The chronic sub-lethal water-borne Cu exposure to the fish exerted that fish had significantly decreased final body weight in comparison to control group. The copper sulfate also had significant negative effects on specific growth rate (SGR) and feed conversion efficiency (FCE) in comparison to those fed the control group. The feed conversion ratio (FCR) and condition factor (CF) were significantly increased in comparison with the control group (P < 0.05). Also survival rate in experimental treatments in comparison with control group, was significantly decreased (P < 0.05). The treated fish exhibited significantly lower body weight and length gains than that of control. The increments of fish weights, fork and total lengths, condition factor, feed intake and condition factor of treated and control fish varied significantly during study period. Hence, concluded that copper sulfate is toxic for Caspian sea kutum (Rutilus frisii kutum).

“…This has already been shown in a number of aquatic animals exposed to copper, which is known to affect a range of endpoints such as oxygen consumption, blood variables, and energy efficiency (US EPA, 2003), with possible consequences on individual performances. Such effects have been extensively investigated in fish (DeBoeck et al, 1997a, b;Handy et al, 1999;Smith et al, 2001;Campbell et al, 2002;Ali et al, 2003), amphibians (Mounaji et al, 2003;Carattino et al, 2004;Redick and La Point, 2004), and molluscs (Widdows and Johnson, 1988;Belanger et al, 1990;Cheung and Wong, 1998;Elfwing and Tedengren, 2002). Effects of copper on the energetic costs associated with individual performances have also been studied in arthropods.…”

When spiked in sediments, copper is known to reduce growth of Chironomus riparius larvae and the production of eggs by adult females. The aim of this work was to better understand the origin of these phenomena by studying the effects of copper using developmental and energetic biomarkers, such as changes in larval weight and age and changes in the levels of sugars and lipids. Four-day-old C. riparius larvae were exposed to nominal concentrations of copper of 0, 6.5, 12.5, 25 and 50 mg/kg of dry sediment (silica) in 0.6 l beakers. They were fed ad libitum and exposures were stopped at 7 and 9 days after the beginning of the tests. The larvae were weighed, sexed and aged. For each sex, the larvae belonging to the phases the most frequently found in the beakers were selected for dissection and measurement of energy reserves. The increase in the concentration of copper resulted in an increasing delay in larval growth in both sexes. Desynchronized development was observed, as shown by the increase in the number of individuals that remained in the third instar or early phases of the fourth instar, as well as by a reduction in age of males. Concerning energy reserves, the levels of sugars (glycogen, trehalose and glucose) in the dissected larvae remained almost constant among levels of exposure. In contrast, at the highest copper concentration (50 mg/kg), triglyceride levels suffered a slight reduction whereas the level of free glycerol significantly increased. It is concluded that selection of C. riparius larvae for both sex and age improves the relevance of some energy-yielding substrates as indicators of adverse physiological effects of copper.

“…Swift and simplified information allied to the advantages gained by the fish is conveyed by condition factor which seizes immense connotation, for the reason that diminution in condition factor causes hypoxia that entails negative effect on the feed intake of fish, moreover lessens Table 2 Mean values of physico-chemistry variables determined during growth trails for treated and control fish species condition factor and growth also (Randall and Yang, 2004). Ali et al (2003) observed significant variations in specific growth rate and condition factor and weight gains of Oreochromis niloticus grown under different sub-lethal concentration of water-borne Cu. Dethloff et al (2001) found no significant difference in condition factor values of rainbow trout collected from different sites polluted with Cr, Cd and Se.…”

This studied was conducted to evaluate the correlation between water physico-chemical parameters and the growth performance of two fish species viz. Ctenopharyngodon idella and Hypophthalmichthys molitrix. Fish were exposed to sub-lethal (1/3rd of LC 50 ) concentrations of metal mixture under controlled laboratory condition for 90 days. All physical and chemical parameters were determined twice a day through out experimental period. Water pH (7.25), total hardness (225 mg/L as CaCO 3 ) and temperature (30°C) of water were kept constant during each trail for fish. Correlation and regression analyses were computed to find-out relationships among various parameters defined for this study. During growth periods of 90 day, both fish species were monitored weekly for their increase in average wet weights (g), fork and total lengths (mm), specific growth rate, condition factor, feed intakes and feed conversion efficiency. No fish species showed any mortality during the entire period of growth trails under chronic stress of metal mixture. The relationships among all phyisco-chemical and growth parameters were investigated after 90-day growth trail. The obtained results showed that physico-chemistry of metal mixture stressed media exerted significant effect on both fish growth. Significantly better feed intake increased the ammonia production and excretion by both fish resulting fish weight increments positively non-significant correlated with contents of stressed media and also cause significant effect on growth of fish. Total ammonia content of test media exhibited significantly direct relationship with dissolve oxygen. However, calcium showed significantly inverse correlation with magnesium by the both fish species. It is also concluded that not only toxicity of metals but also the deficiency of consumed oxygen cause frequent deaths of fish in water due to biological decomposition of heavy metals.
