N2  - A beam trawl was used to sample fish associated with the seagrass Posidonia australis  between September 1988 and June 1990. We describe variation in abundance of fish  at two spatial scales: among three seagrass beds 1-10 km apart within each of three  estuaries, and among the estuaries separated by at least 100 km. Most species had  significant differences in abundance among sites and estuaries that changed through time.  However, many species also had consistent patterns in abundance among sites and among  estuaries. For example, there were large and consistent differences in the abundance of  many species among the three estuaries. Widespread changes in abundance (ie: changes  that took place at all sites within an estuary or in most estuaries) were not common.  The two spatial scales used in this study are also logical scales for management of seagrass  habitats. The consistent differences in abundance of some fish found at both spatial scales  will complicate management decisions.
