Brief description
Starch-gel electrophoresis was used to investigate population structure of the commercially and recreationally exploited abalone, Haliotis roei. Samples were obtained from abalone taken from 10 sites in south-western Australia between March 1997 and April 1998.Lineage

Statement: Samples of H. roei were collected from 10 sites along the south-west and south coasts of Australia, between Kalbarri in Western Australia and West Island in South Australia (see thumbnail). Sites were chosen to include a range of spatial scales. The shortest over-water distance between sites ranged from 13 km (Burns Beach to Waterman's Reserve) to just over 3000 km (Kalbarri to West I.). Samples were obtained between March and May 1997. Repeat samples were taken from two sites, Kalbarri and Canal Rocks, during April 1998. In the repeat samples, animals smaller than those collected in the original sample were targeted. This, combined with the ~1 year of growth between sampling times, aimed to ensure that they were not from the same cohort.
Between 48 and 50 animals were analysed from each sample, giving a total of 624 animals. Tissue samples from adductor muscle and hepatopancreas were extracted on site and frozen in liquid nitrogen. Samples were stored at -70°C prior to electrophoresis.

Purpose
To assess the size of management areas, the scale of research studies and issues of translocation. Aquaculturists require this knowledge to assess the potential for adaptive divergence available from different sources of broodstock.
