What water quality issue will quickly drive yabbies out of a farm pond or urban waterway?
Answer
Low dissolved oxygen levels
While yabbies can tolerate turbid or cloudy water, which is common in many inland Australian rivers, they have a strict requirement for adequate levels of dissolved oxygen to survive. Conditions leading to low dissolved oxygen—often resulting from excessive organic decay in a poorly managed farm pond or a polluted urban waterway—create an environment that is immediately lethal or forces the crustaceans to abandon the area swiftly. This chemical parameter is more critical for immediate survival than structural elements like logs or specific depth measurements.
