Brief description

The abundances of recruit, juvenile and adult fishes of 36 common species in the Lord Howe Island lagoon system were estimated in November and December 2003. Twenty hard substrata reef sites were sampled by SCUBA divers swimming along three virtual transects per site. Virtual transects were measured using a sonar navigation system (see Patterson et al 2007 for details). Divers recorded species and life history stage of each individual based on size or other characteristics such as colouration or morphology.

Notes

Credit
Heather Patterson and Steve Swearer were supervisors in this Honours project.
Purpose
This survey was undertaken to estimate the spatial variation in abundances of fish species at different life history stages within the lagoon system of Lord Howe Island and to identify sites of importance for recruits and juveniles.
