“…In addition, after exposure to a sublethal concentration (1.44 mg/l) of lead for 30 days, it was evident that lead inhibits oxygen consumption in Penaeus indicus; similar results have been obtained with other crustaceans studied (Chinni et al 2000). Those authors assumed that cytological damage should be related to the decrease in oxygen consumption, because the gills are most likely the first target of waterborne heavy metals, including thickening of bronchial epithelium and deep changes in hemolymph patterns in the gills, with a concomitant increase in vacuolization and reduced hemolymph spaces, causing perfusion stagnation.…”

“…However, when exposed to lethal concentrations of heavy metals, dysfunction of ammonium excretion control follows gill damage. Chinni et al (2000Chinni et al ( , 2002 found that ammonium excretion was inhibited in P. indicus postlarvae exposed to sublethal concentrations of lead. Although there is still no confirmed evidence, it is assumed that the decrease in ammonia-nitrogen excretion by P. indicus postlarvae in the presence of toxicants can be attributed to a reduction in the metabolic rate or to an interaction of lead with pathways for the production of ammonia-nitrogen.…”

In Brazil, pink shrimp (Farfantepenaeus paulensis) is an important commercially exploited species and is an ideal animal for studying the impairment caused by the effects of heavy metals that are often detected in coastal areas. The main purpose of the present study was to detect the acute toxicity of cadmium and zinc to F. paulensis and investigate their effects on oxygen consumption and ammonium excretion, investigations that have not been carried out in this species before. First, the acute toxicity of zinc and cadmium to F. paulensis for 24, 48, 72, and 96 h--medium lethal concentration was examined, which resulted in the following values: 9.39, 6.00, 4.88, and 3.31 mg/l for zinc and 2.35, 1.67, 1.26, and 0.83 mg/l for cadmium. Furthermore, we also found that exposure of shrimp to zinc and cadmium caused an inhibition in oxygen consumption of 25 and 32.4%, respectively, relative to the control. In addition, after separate exposure to cadmium and zinc, elevations in ammonium excretion were obtained, which were 42.85 and 51.85% higher than the control, respectively.

“…The determination of the critical oxygen concentrations for regulating oxygen consumption provides important information on the physiological condition of the organism (Chinni et al 2000). On day 0, increased oxygen consumption in exposed common carp was observed in the exposed groups.…”

“…The oxygen consumption analysis was carried out using a method described by Chinni et al (2000) with slight modification. Groups of 20 fish were randomly sampled and placed in 50-L glass beakers; triplicate fish were then respectively exposed to a test solution of 0.0, 1.0, 2.0, 4.0, or 8.0 mg L -1 .…”

“…Oxygen consumption is widely considered to be a critical factor for evaluating the physiological response and a useful variable for an early warning for monitoring aquatic organisms (Chinni et al 2000). Like most fish, common carp (Cyprinus carpio) are oxygen regulators, i.e., they maintain their oxygen consumption at a constant level along a gradient of environmental oxygen concentrations, until a critical oxygen concentration is reached, and below which oxygen consumption begins to fall.…”

The purposes of this study were to investigate the acute toxicity and effects of sublethal antimony (sb) concentrations on respiratory activity changes in the common carp (Cyprinus carpio). Median lethal concentrations were determined in acute tests. The 96-h LC50 value was 14.05 (11.09~17.80) mg L(-1). Common carp were exposed to 4 different sublethal levels of antimony (1.0, 2.0, 4.0, and 8.0 mg L(-1)) over a 28-day test period and a 14-day recovery period. On days 14 and 28, decreases in oxygen consumption were significant (p < 0.05) for the higher-exposure level groups (4.0 and 8.0 mg L(-1)). An increase in oxygen consumption was observed in the recovery period (on day 42) compared to the respective groups at the same level on day 28 at the higher exposure levels.

This investigation sought to assess the biological responses to Pb along a simplified four-level food chain, from the primary producer, the microalgae Tetraselmis suecica, grown in a control medium with < 1 µg/L of Pb and exposed to a sublethal dose (20 µg/L of Pb) and used as the base of a simulated food chain, through the primary-, secondary-, and tertiary-level consumers, namely, the brine shrimp, Artemia franciscana; the white-leg shrimp, Litopenaeus vannamei; and the grunt fish, Haemulon scudderi, respectively. Growth of Pb-exposed T. suecica was 40% lower than that of the control cultures, and survival of A. franciscana fed this diet was 25 to 30% lower than the control. No differences in the growth rates of Pb-exposed and control shrimp and fish and no gross morphological changes were evident in the exposed specimens. However, the exposed shrimp and fish had 20 and 15% higher mortalities than their controls, respectively. In addition, behavioral alterations were observed in exposed shrimp and fish, including reduction in food consumption or cessation of feeding, breathing air out of the water, reduction of motility, and erratic swimming. The negative correlation between Pb concentration in whole body of shrimp and fish and Fulton's condition factor suggested also that the exposed organisms were stressed because of Pb accumulation.
