In Brazil, Hyphessobrycon callistus is an important commercially exploited species and it is an ideal animal for studying damages caused by the effects of heavy metal that are often detected in the aquatic environment. The main purpose of the present study was to detect the acute toxicity of Cd to H. callistus 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. Acute toxicity of Cd to H. callistus in 24h, 48h, 72h, and 96h medium lethal concentration (LC50) was showed to be 45.95, 32.49, 28.28, and 15.16 mg/l, respectively. Furthermore, it was found that exposure of fish to 1.5 mg/l Cd caused reduction in oxygen consumption and ammonium excretion of 59% and 71.5%, respectively as compared to controls.

“…Several studies have reported the concentration and toxicity of cadmium in shrimps (Páez-Osuna and Ruíz-Fernández, 1995b;Páez-Osuna and Tron-Mayen, 1996;Vanegas et al, 1997;Soegianto et al, 1999;Pourang and Amini, 2001;Kargin et al, 2001;Pourang et al, 2004;Wu and Chen, 2004;Seebaugh et al, 2005;Santos et al, 2013). The Cd concentrations in the shrimp body depend mainly on their levels in the environment since this element is not essential in the biochemical and physiological processes of this animal (Ruelas-Inzunza and Páez-Osuna, 2004).…”

“…Shrimp farms generally are located next to the coast and use the seawater directly from the coastal area to farm shrimps (Wu and Chen, 2004). Coastal zones located near major urban areas are often subjected to severe contamination (Diodato et al, 2012), such as trace elements, which are often problematic environmental pollutants.…”

In this study, concentrations of trace elements in tissues of shrimp species (Litopenaeus vannamei) from farming and zone natural coastal located in the northeastern Brazil were investigated. The elements determination was performed by optical emission spectrometry with inductively coupled plasma (ICP OES). The following ranges of concentrations in the tissues were obtained in µg g -1 dry weight: Al: 13. . The shrimp muscle can be a good iron source (about 88.9 mg -1 g dry weight). The distribution of Se concentration in tissues showed much variation between locations, and the concentration levels found in shrimp muscles of wild samples were high, where its levels in 67% of muscle and 50% of others tissues samples exceeded the ANVISA limit, indicating evidence of selenium bioaccumulation. Distribuição de elementos traço em tecidos do camarão Litopenaeus vannamei (Boone, 1931) da Bahia, Brasil ResumoEsse estudo teve como objetivo avaliar as concentrações de elementos traço em tecidos da espécie de camarão Litopenaeus vannamei coletadas da zona costeira e de carciniculturas localizadas no nordeste do Brasil. Os elementos químicos foram determinados por espectrômetro de emissão óptica com plasma indutivamente acoplado (ICP OES). Foram encontradas as seguintes faixas de concentrações desses elementos nos tecidos (em mg g -1 peso seco): Al: 13,4-886,5; Cd: 0, 80; Cu: 24, Fe: 3, Mn: 0,4; Se: 0,81 and Zn: 20,4. O músculo do camarão investigado pode ser uma boa fonte de ferro (cerca de 88.9 mg-1g peso seco). A distribuição da concentração de Se nos tecidos apresentou muita variação entre as localidades, com níveis acima do estabelecido pela ANVISA para 67% dos musculos e 50% dos outros tecidos investigados, indicando evidências de bioacumulação do selênio. Houve correlações significativas entre os seguintes pares de elementos:: Fe-Zn (r= -0,70), Mn-Cu (r= -0,74), Se-Cu (r= -0,68), Se-Mn (r= 0,82) nos músculos, Fe-Al (r= 0,99), Mn-Al e Mn-Fe (r= 0,62), Se-Al (r = 0,88), Se-Fe (r= 0,87), Se-Mn (r= 0,58) no exoesqueleto e Cu-Zn (r = 0,68), Al-Cu (r= 0,88), Fe-Cu (r= 0,95) and Fe-Al (r= 0,97) nas vísceras.Palavras-chave: Baia de Todos os Santos, camarão, elementos traço, bioacumulação, ICP OES.

Assessment of respiratory and ion transport potential of Penaeus japonicus gills in response to environmental pollution

The present study aims to pinpoint the respiratory and ion transport potential of gills of Penaeus japonicus living in Abu-Qir Bay, East of Alexandria, Egypt. Our results revealed clear histological impairments in gill structure. These alterations were mainly represented by the presence of large vacuoles in gill axis and gill lamellae. In addition, narrow, disrupted gill lamellae with wavy cuticle and shrunk pillar cells were detected. Moreover, some cells clearly showed pyknosis. Gill ultrastructure also showed abnormal chromatin condensation inside the nucleus. Obvious alterations in the typical shape and structure of mitochondria were observed. Noticeably, the main characteristics of ion regulating gill epithelium were absent thus suggesting a low ion transport activity of P. japonicus gills. Statistically, this was further proved by the significantly higher activity levels of respiratory enzymes, namely, lactate dehydrogenase (LDH) and succinate dehydrogenase (SDH) compared to those of the ion transport enzymes, namely, adenosine triphosphatase (ATPase) and carbonic anhydrase (CA) in gills and haemolymph. SDH activity levels were higher than the corresponding levels of LDH in gills and its own level in haemolymph, indicating a contradictory effect of pollution on respiratory enzyme activity levels.
