“…This has been attributed to depletion of muscle energy fuels (PCr, ATP and glycogen) and accumulation of metabolic end products (lactate and ammonia) [50]. The present study has shown that low level (0.01 mg L 1 ) cadmium exposure enhanced erythropoiesis, increased plasma levels of cortisol, glucose and lactate, decreased muscle glycogen and ATP, and increased muscle protein and lactate.…”

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.

“…Therefore, the aims of the present study were: 1) to provide baseline hematological information in 'all-fish' growth hormone transgenic carp and 2) to assess if and how the hematological patterns for transgenic carp in response to exhaustive exercise are modified compared to controls. Information on this variability would provide important insights into the ecological differences/requirements between transgenic carp and controls with respect to exercise performance (Kieffer, 2000).…”

“…We examined several metrics of physiological stress which generally show up in the blood plasma within an hour, but persist for several hours after initial response (Postlethwaite and McDonald 1995;McDonald and Milligan 1997;Wendelaar Bonga 1997). Specifically, plasma lactate and glucose were measured as elevated levels of these metabolites are indicative of anaerobic swimming and exhaustive exercise (Wood 1991;Kieffer 2000). Plasma ions (Na…”

Abstract.-We investigated the effect of changes in water discharge from the Seton River Dam, British Columbia, on the physiological condition, passage time, and passage success of adult migrant sockeye salmon Oncorhynchus nerka. Sockeye salmon were intercepted and nonlethally biopsied for blood plasma and energy status. A subset of these fish were fitted with radio transmitters and tracked under three different operational attraction flow levels. Indices of physiological stress and exhaustive exercise (e.g., plasma cortisol, glucose, lactate, osmolality, and hematocrit) did not differ among the attraction flow discharge levels that were examined, nor did they differ appreciably from those of other adult Fraser River sockeye salmon studied during upriver migrations in areas of natural, nonregulated flows. In fact, the fish appeared relatively unstressed after dam passage. Passage time was significantly longer (19.9 h) under intermediate discharge (12.7 m 3 /s) than under high (15.8 m 3 /s) or low (11.0 m 3 /s) discharges (9.3 and 7.0 h, respectively) but did not differ between high-and low-discharge periods. No differences in passage success or fishway ascent time were observed among the three discharges. Though we suspect that unique flow conditions were responsible for the longer passage time during intermediate discharge, a detailed hydraulic analysis is needed to further interpret our results.
