12 Species Case Studies
Fig . 12.1 Adult brown-marbled grouper ( Epinephelus fuscoguttatus ) ( a ) in typical colouration.

Biological information comes from a recent age-based study on Australia’s
Great Barrier Reef (GBR) (Pears et al . 2006, 2007 ) , unless otherwise noted.
Brown-marbled grouper are uncommon (less than 1 fish per 1,000 m
2 ), and
relatively long-lived (lifespan can reach 42 years, Fig. 12.2 ). The length-weight relationship was estimated to be: W (g) = 1.16 × 10
−5 FL (mm) 3.075 (n = 127, r
2 = 0.98).
