Sublethal effects of ammonia on rainbow trout (Oncorhynchus mykiss) were investigated at
stages of its development (embryos, larvae, and adult fish) using morphological and …

Crayfish extract information from chemical stimuli during social interactions. Commercial
fertilizers increase background ammonia concentrations which may interfere with chemical …

Adult trout Oncorhynchus mykiss fitted with a dorsal aortic catheter were exposed to
288±15μmoll− 1 (mean±sem) total ammonia for 24h in water at a pH of 8.39±0.02, while …

We tested whether exposing fish to low ammonia concentrations induced acclimation
processes and helped fish to tolerate subsequent (sub) lethal ammonia exposure by …

Ammonia is toxic to most bony fishes. However, little information is available on the
toxicology mechanisms induced by ammonia and the means to mitigate the effects by …

An appropriate approach to assess the effect of toxicants on aquatic animals is to monitor
behavioral endpoints, as they are a link between physiological and ecological processes. A …

Using a continuous-flow method a total of 14 acute toxicity bioassays were conducted using
seabass (Dicentrarchus labrax), seabream (Spams aurata) and turbot (Scophthalmus …

Rainbow trout (Oncorhynchus mykiss) were exposed for up to 4 days to 100, 300 and 500
μM ammonia and 0, 300 and 600 μM nitrite. Each ammonia concentration was combined …

Many teleosts have evolved mechanisms to cope with ammonia toxicity in the brain when
confronted with high environmental ammonia (HEA). In the present study, the possible role …

The objective of this study was to determine the underlying physiological and molecular
responses to long-term sublethal ammonia exposure in Atlantic salmon (Salmo salar) parr …
