The toxicological and environmental significance of N-containing effluents discharged to
seawater from fish farms is difficult to establish. Environmental quality standards for N …

Publisher Summary Most experimental studies have concentrated on fish that are confined
in small chambers and therefore not swimming, feeding, or growing; the fish are often …

The basic pathways of intermediary metabolism that have been investigated so far in
salmonid fish are very similar to those occurring in mammals and other animals, though …

Diurnal ammonia excretion rate was measured for 3-, 40-and 90-g gilthead seabream at 24°
C at 4-hourly intervals in experimental tanks. The excretion rates reached peaks of 70, 36.4 …

Nitrogen (ammonia a. nd/or urea) excretion in carp and rainbow trout kept under different
feeding regimes was continuously monitored over 24-hr cycles. The daily nitrogen excretion …

This study aimed to determine excretion rates of ammonia and urea of Australian short-
finned elvers as influenced by varying dietary crude protein intake. Elvers (2.3±0.02 g) were …

Ammonium‐nitrogen accounted for 75–85% of the nitrogenous excretion of young plaice,
Pleuronectes Platessa L., prior to feeding. Rates of excretion increased with increasing …

Oxygen consumption, carbon dioxide excretion and nitrogen excretion from 2 kg Atlantic
salmon Salmo salar L. were studied at land‐based outdoor tanks, throughout a 10 day …

This study examines the interaction of predation and resource‐based effects of fish on
freshwater periphyton communities. Current theory predicts that fish primarily influence …

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 …
