Aluminium toxicity to rainbow trout at low pH
An acute toxicity study of aluminium at low pH, using one-year-old rainbow trout (Salmo gairdneri R.), was performed in a closed recirculating system at pH 5.2, 5.4, and 5.6 with nominal concentrations of 0, 100, 200, and 400/tg A1/I. Mortality (96 h) was dependent on the pH and aluminium concentration. Measurements of aluminium in the plasma of exposed fish, by electrothermal atomic absorption...
متن کاملChronic Toxicity of Ammonia to Early Life Stage Rainbow Trout
—A 90-d ammonia toxicity test for early life stage rainbow trout Oncorhynchus mykiss was conducted using newly fertilized eggs from a wild strain of fish. The toxicity test was conducted at a pH of 7.75 and temperature of 11.48C. Hatch success and survival of sac fry were not affected by ammonia exposure. Survival, growth, and biomass of swim-up fry were significantly reduced at an ammonia-nitr...

متن کاملEffects of zeolite on growth and hematology of rainbow trout (Oncorhynchus mykiss) kept at low temperatures
It is known that zeolite, tested in animal feeds in recent years, has a positive effect on fish growth and many physiological parameters. For this purpose, rainbow trout (Oncorhynchus mykiss) was fed with feeds containing zeolite at different rates (1%, 3%, and 5%) for three months in the present study. Fish growth parameters (live weight gain, specific growth rate, feed conversion rate, condit...
متن کاملBRANCHIAL AND RENAL ACID AND ION FLUXES IN THE RAINBOW TROUT, SALMO GAIRDNERI, AT LOW ENVIRONMENTAL pH
Rainbow trout were exposed for 4 days to an environmental pH averaging 4-2, an exposure which resulted in a continuous net branchial influx of acid. The influx provoked a progressive depression in blood pH and [HCO3~], virtually complete by 48 h, and a marked increase in renal acid excretion, also complete by 48 h. The increase in the latter was sufficient to remove, at maximum, about half of t...
