Stress in fish can be assessed by means of a bioenergetic approach, based on the evaluation of changes in their physiological parameters. The objective of this study was to determine the impact of sublethal water-borne cadmium (Cd) on the energetic balance of juvenile Cyprinus carpio under laboratory conditions after a short-term exposure. Fish were exposed to a concentration of Cd (0.15 mg Cd l(-1)) for 2 weeks. This concentration is environmentally realistic since it is usually found, even at higher values, in heavily polluted periurban water bodies of Argentina. No mortality was recorded among the animals used in the experiments. Food intake, food assimilation and assimilation efficiency, fecal production, liver glycogen content, oxygen consumption, oxygen extraction efficiency, specific metabolic rate, ammonia excretion and ammonia quotient (AQ), condition factor, and liver somatic index were determined. The overall balance was expressed as the scope for growth (SFG). The morphological indices and the liver glycogen content of Cd-exposed fish showed no significant differences when compared to those of controls. There was a significant decrease in the food intake, fecal production, and food assimilation rates as well as in AQ; the SFG exhibited a highly significant decrease. The remaining parameters (assimilation efficiency, oxygen consumption, oxygen extraction efficiency, specific metabolic rate, and ammonia excretion) increased after the exposure to Cd. We concluded that the sub-chronic exposure of Cyprinus carpio to a sublethal concentration of Cd causes important alterations in the energy-related homeostasis of fish. Most of the responses are indicative of physiological adaptations to compensate an increased energy requirement due to the impairments caused by the metal.

“…Recently, Kolarevic and colleagues (Kolarevic et al, 2012) reported a very high resting plasma T Amm level (up to 1.5mmoll -1 ) in Atlantic salmon (Salmo salar), which was sustained chronically (up to many days) without ill effects, as evidenced by an unchanged growth rate. Moreover, a relatively high basal level of plasma T Amm was also evident in the goldfish (0.8-1.4mmoll -1 ) (Liew et al, 2012;Sinha et al, 2012a;Smith et al, 2012) as well as in the carp (0.6-1.1mmoll -1 ) (De Boeck et al, 2006;Liew et al, 2012). There is some evidence that cortisol may also contribute to the regulation of urea production in fish (Hopkins et al, 1995;Mommsen et al, 1999;Vijayan et al, 1996) and experimentally elevated plasma cortisol increased urea-N excretion rates (J urea ) in trout (McDonald and Wood, 2004).…”

“…As plasma lactate did not increase until 72 h of exposure when muscle lactate had recovered to the control level and had begun to accumulate, it is unlikely that the initial decrease in muscle lactate was caused by the leakage into the blood space. Significant decreases of muscle lactate were also observed in common carp (Cyprinus carpio) after 3 and 7 days of exposure to copper, where it was speculated that muscle lactate was used as an energy source in aerobic metabolism [38]. In addition, previous studies have shown that muscle glycogen resynthesis occurred in situ using lactate as the primary substrate.…”

“…Many previous studies have demonstrated that the swimming performance of fish is impaired by metal exposure, including rainbow trout (Oncorhynchus mykiss) [4446], brown trout (Salmo trutta) [4749], common carp (Cyprinus carpio) and gibel carp (Carassius auratus gibelio) [38]. This has been attributed to depletion of muscle energy fuels (PCr, ATP and glycogen) and accumulation of metabolic end products (lactate and ammonia) [50].…”

Cadmium is a non-essential metal with a wide distribution that has severe toxic effects on aquatic animals. Changes in hematology and muscle physiology were examined in silver carp (Hypophthalmichthys molitrix) exposed to environmentally relevant levels of cadmium (0.01 mg L 1 ) for 96 h. Cadmium exposure induced significant increases in the red blood cell count, and in the plasma concentrations of cortisol, glucose, and lactate. This suggests that the dose of cadmium was sufficient to cause stress, possibly associated with impaired gas exchange at the gills. There were no changes in hemoglobin concentration or plasma protein concentration. Significant decreases in muscle energy fuels (ATP and glycogen), and increases in muscle lactate persisted until the end of the exposure period, respectively. The changes in muscle lactate and protein in silver carp differed from those observed in response to exposure of fish to cadmium and heavy metals in other studies. The study highlights the importance of selecting unpolluted release sites with suitable water conditions for the survival of newly released individuals for stock enhancement of the Xiangjiang River. silver carp, hematology, muscle physiology, cadmium exposure, stock enhancement Citation:Zhang T, Zhang Y, Li D L, et al.
