Determination of Blood Ammonia Using the Ammonia Checker [PDF]
A new diffusion method employing bromocresol green for determination of blood ammonia (Ammonia CheckerR) using disposable reagent test-plates and a pocket-size colorimeter with direct readout of results was compared with an enzymatic method. The values obtained with the Ammonia Checker were slightly lower than those with the enzymatic method.

The effect of a sudden temperature decrease on selected physiological indices in the common carp
The objective of the study was to evaluate stress invoked by a temperature decrease in the common carp (n = 56). After acclimatisation to laboratory conditions at a temperature of 27.8 ± 1.0 °C, the fish (n = 28) were transferred to 16.8 ± 1.0 °C water ...
