Effects 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 کاملBlood Respiratory Properties of Rainbow Trout {salmo Gairdnert) Kept
1. Blood O2 transport and acid-base balance were studied at 20 °C in rainbow trout (Salmo gairdneri) which had been kept in water of high COa content (15 mmHg) for at least a week. Also the blood gas chemistry of fish rapidly entering or leaving the hypercapnic environment was studied. 2. Fish entering high COa water suffered a sharp decrease in blood pH which significantly reduced O2 transport...
متن کاملFeed efficiency of rainbow trout can be improved through selection: different genetic potential on alternative diets.
To assess the genetic potential for selection of increased feed efficiency in rainbow trout (Oncorhynchus mykiss), we estimated the heritabilities and correlations for BW, daily weight gain (DG), and daily feed intake (DFI). Body weight was recorded 5 times, and DG and DFI 3 times during a feeding trial lasting 22 mo. To test the hypothesis that phenotypic and genetic parameters were influenced...
متن کاملAluminium 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 کاملElimination of chloramphenicol in rainbow trout receiving medicated feed.
Chloramphenicol muscle residue levels in rainbow trout were determined after oral administration of 84 μg kg-1d-1 of chloramphenicol for four days. Samples were taken one day before treatment and for 43 days after the treatment was over. Chloramphenicol was analysed using an in-house enzyme linked immunoassay (ELISA) validated against the criteria of the Commission Decision 2002/657/EC. Validat...
