All the footage was taken during a survey in Haida Gwaii ( Queen Charlotte Islands), May 2002. The survey was a collaboration between the Haida Fisheries Program and DFO.

An abalone, as divers see it underwater, moving from one boulder to another. When trying to escape from a sunflower starfish, (see 'Red sea urchin escape' video below), abalone can move faster than what is shown in this clip. Click on image at left to view Quicktime movie (16.7 MB).
Abalone condos are made from crab traps filled with cut up concrete blocks.
Haida Fisheries Program biologist and divers modified the original design from
Gary Davis in California (Davis, G. E. 1995. Recruitment of juvenile abalone (Haliotis
spp.) measured in artificial habitats. Marine and Freshwater Research 46:
549-554) to provide artificial habitat for juvenile abalone. The video
demonstrates how each condo is surveyed.

This clip demonstrates how abalone are tagged with a numbered plastic disk. Once put back into the ocean, each tagged abalone can be individually identified and we can monitor its movement and growth. Click on image at right to view Quicktime movie (11 MB).
This clips shows red sea urchins trying to escape from a sunflower starfish (Pycnopodia helianthoides). The first 10 seconds of the clip are at normal speed; the video is then accelerated to show the urchins trying to move away. The sunflower starfish is probably the major predator of abalone. Abalone also flee the sunflower starfish at a speed faster than the urchins. Click on image at left to view Quicktime movie (1.6 MB).
