Acute stress may affect metabolism and nitrogen excretion as part of the adaptive response
that allows animals to face adverse environmental changes. In the present paper the acute …

Due to eutrophication, high environmental ammonia (HEA) has become a frequent problem
in aquatic environments, especially in agricultural or densely populated areas. During …

High environmental ammonia has become a universal problem for aquatic animals,
especially in fish and induces a range of ecotoxicological effects. Perhaps waterborne …

Abstract The slender African lungfish, Protopterus dolloi, does not aestivate in a
subterranean mud cocoon, but is capable of aestivating inside a layer of dried mucus on …

Seabream and turbot juveniles (40–520 g) were exposed to constant exogenous NH3-N
concentrations (1.27–4.27 mmol/l; pH, 8.15). In 96 hr acclimated fish, plasma TA-N (total …

Abstract The African sharptooth catfish Clarias gariepinus lives in freshwater, is an
obligatory air breather, and exhibits high tolerance of environmental ammonia. This study …

Stressful husbandry conditions are likely to affect growth and amino acid metabolism in fish.
In this study, chronic ammonia exposure was used to test the effects of a stressor on growth …

The effects of ammonia exposure and recovery on oxidative stress parameters and histology
of juvenile Brazilian flounder Paralichthys orbignyanus were evaluated. The fish were …

At a field site in Belize, mangrove killifish Rivulus marmoratus inhabit hypersaline waters (up
to 48‰) containing approximately 1 mmol l–1 ammonia. We tested the hypotheses that R …

One of the most critical factors affecting aquaculture efficiency is the capability of releasing
ammonia from the water. By applying a high salinity strategy, this study provides a prompt …
