FIGURING OUT WHEN AMMONIUM LEVELS ARE TOO HIGH
FIGURING OUT WHEN AMMONIUM LEVELS ARE TOO HIGH… September 10, 2012 I had a minor freakout at the polytunnel today when on testing the ammonium levels were at 3mg/l. So why are the fish not even the teenyest bit dead? Here they all are – not one lost by the way since aquiring them… yet even…

The respiratory system
The respiratory system Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels, which give gills a bright red colour. Water taken in continuously through…
