Fine-scale associations between blacklip abalone (Haliotis rubra) and encrusting algae

The survey comprises two streams of data, including (1) the availability of different attachment sites and (2) the algal composition of abalone attachment sites ('homesites'). The survey was conducted at three sites at each of three regions on the east coast of Tasmania.

Statement
Surveys were conducted in the 2 - 6 m depth range. At some sites, high densities of abalone also extended to deeper water and for these sites, surveys were conducted in 2 depth strata (2 - 6 m, 8 - 12 m). Availability of potential abalone attachment substrates was measured by randomly surveying understorey community structure at each site. Understorey algal composition was assessed in ten replicate 0.25 x 0.25 m quadrats randomly positioned along a 20 m long transect that was deployed haphazardly from the surface and aligned parallel to the shore. Within each depth strata individual homesites were characterised from a random sample of at least 100 emergent abalone. Each abalone was carefully removed from the reef surface, allowing the algal composition of the "homesite" to be characterised. The homesite was the area directly beneath the aablone shell. For each homesite a number of variables were recorded, including percentage cover (estimated to the nearest 10 % by eye) of different attachment surfaces, abalone shell length and attachment surface orientation.
