“…Despite their regulatory capability, the oxygen consumption rate was indeed inhibited after F. paulensis was exposed to high concentrations of cadmium. Similar results were also observed in different shrimp species (Chinni et al 2002;St-Amand et al 1999;Wu and Chen 2004).…”

“…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.

“…2) exposed to high concentrations of 2,4-D. Similar results have also been observed in different fish species for different chemical substances (St-Amand et al 1999;Chinni et al 2002;Wu and Chen 2004;Barbieri 2007). The significant decrease in the consumption of oxygen is probably the result of alterations of energy metabolism (Olsen et al 2006).…”

Fish form important fisheries and aquaculture resources worldwide. In Brazil, pearl eartheater (Geophagus brasiliensis) is an important commercially exploited species and is an ideal animal for studying the impairment caused by the effects of herbicides that are often detected in the aquatic environment. The main purpose of the present study was to detect the acute toxicity of 2,4-dichlorophenoxyacetic acid (2,4-D) to G. brasiliensis and investigate its effects on oxygen consumption, ammonium excretion, and the neutral red retention time assay to estimate effects at the cellular level. Such investigations have not been carried out before with this species. First, the acute toxicity of 2,4-D to G. brasiliensis in terms of the 24-, 48-, 72-, and 96-h medium lethal concentration (LC(50)) was calculated to be 45.95, 32.49, 28.28, and 15.16 mg/l, respectively. Furthermore, it was found that exposure of fish to 40 mg/l 2,4-D caused reduction in oxygen consumption and ammonium excretion of 59% and 85%, respectively, in relation to the controls. Mean neutral red retention time assay was significantly lower in comparison with control for organisms exposed to 1, 5, 10, and 40 mg/l 2,4-D. However, the effects at the cellular level were progressive, suggesting that the fish are not able to recover from such increasing effects.

“…Direct damage to gill structures and functions caused by exposure to higher levels of heavy metals was rarely studied in prawns. It is only in Penaeus japonicus that the effects of heavy metals on gill structures and functions have been well studied (Bambang et al 1995; Soegianto et al 1999a, b), and relatively less so in other prawn species such as P. indicus (Chinni et al 2002). Even though L. vannamei is a very important cultured prawn species, surprisingly few related investigations have been conducted on it to date.…”

White shrimp, Litopenaeus vannamei, a globally important cultured prawn species, is an ideal animal for studying the impairment caused by the effects of heavy metals that are often detected in coastal areas. In this present study, we detected the acute toxicity of cadmium (Cd) and zinc (Zn) to L. vannamei. Medium lethal time (LT50) values of Cd and Zn on L. vannamei were estimated. Furthermore, we also demonstrated that acute exposure to high concentrations of Cd and Zn resulted in morphological alterations in gills of L. vannamei in this present study.
