Direct observation (see Photo 2.4) to search for S. zanklon in their potential hiding spaces was also conducted.

Photo 2.4: Surveyor searching for S. zanklon on potential hiding space (under rocks) along the watercourse |
All captured S. zanklon individuals would be marked prior to releasing them back to the monitoring area. The marker would be an epoxy-resin based paint (Jotamastic Wintergrade) which contains a metallic component and cures in contact with water. Earlier laboratory and field trials had established that crab survival and behaviour was unaffected by paint marking on the carapace and that the marks persisted in field conditions (Eaton et. al., 2001). Recaptures, if any, would be re-marked with black numerals to indicate the month of capture.
