Table 13: Depth zones used in the vertical gillnet protocol to allocate sampling effort.The littoral zone was further divided into habitat types based on substrate composition, presence of vegetation and proximity to flowing water (see Table 12). Zmax refers to the maximum depth of the lake.

Depth habitats	Details
Littoral	<5 m
Sublittoral	5 m – 10 m
Deep sublittoral	10 m – 30% Zmax
Min pelagic / profundal	30% Zmax – 60% Zmax
Med pelagic / profundal	60% Zmax – 90% Zmax
