Atlantic salmon (Salmo salar L.) postsmolts weighing about 300 g were exposed to two
replicates of six ammonia levels in running seawater at 4–9° C, 34–35‰ salinity, pH 7.7–7.8 …

The aim of the present study was to assess the effect of ammonia exposure at different pH
on survivorship and metabolic parameters in the liver, muscle and gill histology of silver …

Three fish species of the family Batrachoididae, the gulf toadfish (Opsanus beta), the oyster
toadfish (Opsanus tau), and the plainfin midshipman (Porichthys notatus) demonstrated …

The median lethal concentration (LC50) of unionized ammonia (NH3‐N) in longfin
yellowtail, Seriola rivoliana juveniles was assessed after 96 h of exposure using a semistatic …

Ammonia can cause adverse reproductive and mortality effects in individual fish by
interacting with the central nervous system. The last published study that assessed the …

Exposure to ammonia can cause convulsions, coma, and death. In this study, we investigate
the effects of ammonia exposure on immunoregulatory and neuroendocrine changes in …

We compared the feeding performance and overt aggressive behaviour of two closely
related salmonids occupying the same food patches. Foraging competition between pairs of …

The juveniles of tilapia (Oreochromis niloticusO. areus) were exposed to ammonia-N (0, 2.5
mgL-1, 5 mgL-1, 10 mgL-1 and 20 mgL-1) for 0, 12 h, 24 h, 48 h and 72 h to evaluate the …
