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

This study aimed to elucidate the physiological effects of high environmental ammonia
(HEA) following periods of feeding (2% body weight) and starvation (unfed for 7 days prior to …

Waterborne ammonia has become a persistent pollutant of aquatic habitats. During certain
periods (eg winter), food deprivation may occur simultaneously in natural water. Additionally …

Ammonia is an environmental pollutant that is toxic to all aquatic animals. The toxic effects of
ammonia can be modulated by other physiological processes such as feeding and …

The aim of the present study was to assess the effects of ammonia and water hardness on
endocrine, osmoregulatory and metabolic parameters in silver catfish (Rhamdia quelen) …

A study was carried to test the response of yellow catfish for 28 days under two ammonia
concentrations. Weight gain of fish exposure to high and low ammonia abruptly increased at …

The aim of this study was to investigate the effects of ammonia exposure on stress and
immune response in turbot. The species was exposed to five total ammonia nitrogen (TAN) …

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

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 …

Ammonia is a pollutant frequently found in aquatic ecosystems. In fish, ammonia can cause
physical damage, alter its behaviour, and even cause death. Exposure to ammonia also …
