What critical behavior is severely compromised if yabby substrate is too sandy or rocky?
Answer
Surviving dry periods when water bodies shrink
The ability of yabbies to persist through drought conditions is fundamentally dependent upon their burrowing behavior, which requires a suitable substrate. Yabbies burrow into the bottom sediment for protection and survival when water levels drop significantly or water bodies dry up entirely. If the substrate is composed of material that is too sandy or too rocky, they lack the necessary material to create secure burrows, thereby severely compromising their capability to survive these inevitable environmental stresses.
