      Acute ammonia toxicity in rainbow trout (Salmo gairdneri) was studied by intraarterial injection of NH 4 Cl and NH 4 HCO en ion and total ammonia concentrations were measured in blood sampled from the dorsal aorta both before and after by: Rainbow trout raised in fresh water had a higher growth rate ( vs %.d −1), better food conversion ratio ( vs ), better ADC (91 vs 85%) and PPV (45 vs 35%) and lower ammonia excretion rates than brown trout reared in fresh water. Transferring brown trout to sea water induced lower PPV (30%) and ammonia and urea by:

    Kidney and urinary bladder functions of the rainbow trout in Mg and Na excretion. Beyenbach KW, Kirschner LB. Magnesium concentration in the urinary bladder of marine teleosts is high and [Na] is low. The inverse relationship may be due to the coupling of Mg secretion to Na reabsorption through a common tubular transport system or coupling may Cited by:   1. In the freshwater adapted rainbow trout, urine flow markedly increased during periods of exercise in a swimming respirometer. 2. Over a range of oxygen consumptions from “standard” to nearly “active metabolic rates”, oxygen and water fluxes exhibited a highly significant positive correlation in individual fish. The results were indicative of covariation of the oxygen and water Cited by:

RENAL EXCRETION OF MAGNESIU IMN A FRESHWATER TELEOST, SALMO GAIRDNERI BY A. OIKARI* AND J. RANKIN & Dirks, ), 'little is known of the mechanisms that regulate magnesium conserva-tion and excretion' and even less is known about sulphate. Fish plasma magnesium the rainbow trout Salmo gairdneri, to experimental mag-nesium.

Renal excretion of magnesium in a freshwater teleost, Salmo gairdneri Article (PDF Available) in Journal of Experimental Biology August with 44 Reads How we measure 'reads'. The role of carbonic anhydrase in carbon dioxide excretion and acid-base regulation in the rainbow trout, Salmo gairdneri has been investigated.

While a significant amount of carbonic anhydrase was found in the blood of the trout, calculations based on red cell hemolysates suggest that the probable circulating levels of carbonic anhydrase activity in blood may not be sufficient to account for Author: Monty Stephen Haswell.

The plasma half-life of sulfobromophthalein (BSP) for rainbow trout (Salmo gairdneri) was 13 min for doses of 5 and 10 mg/kg and 29 min for a dose of 15 mg/kg. Rainbow trout (Salmo gairdneri) were held in metabolizable energy chambers at Standard Environmental Temperature (15°C) for 72h following a single feeding of a semi-purified test diet containing tracer quantities of a radioisotope of zinc (65Zn) and different combinations of dietary calcium level and zinc source.

Gill wastes, urine, and feces were separately by: Ammonia excretion by brook trout (Salvelinus fontinalis) and rainbow trout (Salmo gairdneri) was measured in relation to nitrogen consumption, body weight (15– g for rainbow trout and 50– g for brook trout), and temperature (– °C) under laboratory natural diets, collected from Castle Lake, California, and a commercial pellet diet were fed to the trout in Cited by: The relative availability of magnesium (Mg) added to semi-purified trout diets was estimated by determining apparent retention.

The majority of the infused load was excreted renally, no net branchial excretion being detected.
