Growth models, age frequency and size frequency distributions of sea urchin populations (Heliocidaris erythrogramma) in native macroalgal beds and sea urchin barrens
Growth models were constructed for two sea urchin populations over a two-year period using a tag-recapture study in the Mercury Passage, Tasmania. Sea urchins were tagged using tetracycline and calcein and growth models constructed using measurements taken from sea urchin jaws.

- Statement
- Approximately 400 sea urchins were tagged at each of the two sites by divers removing all sea urchins from an experimental plot located on the 5-m contour. The experimental plot measured ~ 10 m x 6 m at Lords Bluff and 10 m x 12 m at Four Mile Point. Experimental plots were sampled three times between February 1999 and February 2001 (12, 14, and 24 months post-tagging). Approximately one-quarter of the number of sea urchins originally tagged were recaptured after 12 and 14 months of growth, with approximately half the original number of tagged sea urchins left in the plots to complete 24 months of growth posttagging. The recaptured sea urchins were selected to represent the range of sizes present, and were frozen before dissection in the laboratory. On the final sampling in early February 2001, all remaining sea urchins were removed from the plots and from within a 1-m band around the plots. Further methods can be found in the published paper.
