“…The effects of stress resulting from aquaculture practices on fish and methods of minimizing such effects have received considerable attention through the years (Barton andJwama, 1991, Mazik et al, 1991;Cech et al, 1996). Stress induced by common practices such as handling, crowding, transport or poor water conditions can increase the incidence if diseases and mortality and salinity fluctuations undoubtedly impose stress on the physiology of the exposed fish population and can modify their structure, and is therefore an important factor affecting the economics of aquaculture.…”

ABSTRACT. The changes in some blood biochemical parameters were studied in the freshwater fish N. notopterus under saline exposure for a longer period of 30 days. The blood biochemical parameters are glucose, protein, triglycerides and cholesterol. All these parameters exhibited increased level except of blood glucose which remained unchanged as observed after the termination of saline exposure. Thus it indicates that although fish survives and able to tolerate extreme saline condition as there was no mortality during the exposure period. The increase of blood biochemical parameters can be considered as a kind of saline stress response particularly on lipid derivatives.

“…These differences may be due to the fact that in our study blood was collected immediately after the fish were caught with a shrimp trawl deployed for 5 min. Therefore, fish were subjected to a very stressful situation, and in stressed individuals there is an increase of blood flow to the gill and paracellular permeability (Cech et al, 1996;McDonald et al, 1991), which lead to dehydration and ion influx by diffusion because seawater is more concentrated than plasma (Gallaugher et al, 2001).…”

Plasma ion levels of freshwater and marine/estuarine teleosts from Southern Brazil

et al. 2011

The purpose of this study was to investigate Na , and Mg 2+ levels in the plasma of freshwater and marine/ estuarine teleosts collected at different salinities (0 to 34) from the estuarine and freshwater portions of the São Gonçalo channel in Southern Brazil. Any relationship between plasma ion levels and salinity and the capacity of ionic regulation of teleosts found at three or more different salinities (Genidens barbus and Micropogonias furnieri) was also investigated. Results showed no relationship between plasma ion levels and salinity when considering all species together, but the two species collected from three or more different salinities showed a significant positive relationship between plasma ion levels and salinity, indicating that G. barbus and M. furnieri have a high capacity to regulate plasma ion levels at both low and high salinities.A proposta deste estudo foi investigar os níveis de Na , and Mg 2+ no plasma de teleósteos de água doce e marinhos/estuarinos coletados em diferentes salinidades (0 a 34) nas porções de água doce e estuarinas do Canal São Gonçalo, sul do Brasil. Uma possível relação entre os níveis iônicos plasmáticos e a salinidade também foi investigada bem como a capacidade de regulação iônica dos teleósteos coletados em três ou mais salinidades (Genidens barbus e Micropogonias furnieri). Os resultados mostraram que não houve relação entre os níveis iônicos no plasma com a salinidade quando considerando todas as espécies juntas, mas as duas espécies coletadas em três ou mais salinidades mostraram uma relação significativamente positiva entre níveis iônicos no plasma e salinidade, mostrando que G. barbus e M. furnieri apresentaram uma grande capacidade para regular os íons do plasma em baixas e altas salinidades.

“…This was expected because tamoatás had not been given time to recover from any handling stress after transfer to the chambers, which is very likely to result in net ion loss (Postlethwaite & McDonald, 1995). Stress increases gill blood flow and paracellular permeability, resulting in ion loss (Cech et al, 1996). Recovery is variable depending on the intensity of stress and species (Gonzalez & McDonald, 1994;Baldisserotto & Val, 2002;Rosso et al, 2006).…”

Calcium fluxes in Hoplosternum littorale (tamoatá) exposed to different types of Amazonian waters

et al. 2009

Fishes that live in the Amazonian environment may be exposed to several kinds of waters: ''black waters'', containing high dissolved organic carbon and acidic pH, ''white waters'', with ten fold higher Ca 2+ concentrations than black waters and neutral pH, and ''clear waters'', with two fold higher Ca 2+ concentrations than black waters and also neutral pH. Therefore, the aim of the present study was to analyze Ca 2+ fluxes in the facultative air-breather Hoplosternum littorale (tamoatá) exposed to different Amazonian waters. Fishes were acclimated in well water (similar to clear water) and later placed in individual chambers for Ca 2+ fluxes measurements. After 4 h, water from the chambers was replaced by a different type of water. Transfer of tamoatás to ion-poor black or acidic black water resulted in net Ca 2+ loss only in the first 2 h of experiment. However, transfer from black or acidic black water to white water led to only net Ca 2+ influxes. The results obtained allowed us to conclude that transfer of tamoatás to ion-poor waters (black and acidic black water) led to transient net Ca 2+ loss, while the amount of Ca 2+ in the ion-rich white water seems adequate to prevent Ca 2+ loss after transfer. Therefore, transfer of tamoatás between these Amazonian waters does not seem to result in serious Ca 2+ disturbance.Os peixes que vivem na Amazônia são expostos a vários tipos de água: águas pretas, contendo grande quantidade de carbono orgânico dissolvido, águas brancas, com concentração de Ca 2+ dez vezes maior que as águas pretas e pH neutro, e águas claras, com concentração de Ca 2+ duas vezes maior que as águas pretas e pH também neutro. Dessa forma, o objetivo deste trabalho foi analisar o fluxo de Ca 2+ no peixe de respiração aérea facultativa Hoplosternum littorale (tamoatá) exposto a diferentes tipos de águas amazônicas. Os peixes foram aclimatados em água de poço artesiano (semelhante à água clara) e depois colocados individualmente em câmaras para medir o fluxo de Ca 2+ . Após 4 h, a água das câmaras foi trocada por um tipo diferente de água. A transferência do tamoatá das águas pobres em íons água preta e preta ácida ou da água branca, rica em íons, para as águas preta e preta ácida, pobres em íons, resulta em uma perda de Ca 2+ apenas nas duas primeiras horas de experimento. Entretanto, a transferência da água preta e preta ácida, para a água branca resulta em um influxo de Ca 2+ . Os resultados obtidos nos permitem concluir que a transferência do tamoatá para as águas preta e preta ácida, pobres em íons, leva a uma temporária perda de Ca 2+ , e a quantidade de Ca 2+ na água branca, rica em íons, é adequada para prevenir sua perda após a transferência. Sendo assim, a transferência do tamoatá entre as águas estudadas não resulta em sérios distúrbios no Ca 2+ .
