<DIV>The length frequencies and age structures of resident <EM>Pseudanthias
rubrizonatus</EM> (<EM>n</EM> = 407), a small protogynous serranid, were
measured at four isolated artificial structures on the continental shelf of
north-western Australia between June and August 2008, to determine whether these
structures supported full (complete size and age-structured) populations of this
species. The artificial structures were located in depths between 82 and 135 m,
and growth rates of juveniles and adults, and body condition of adults, were
compared among structures to determine the effect of depth on potential
production. All life-history stages, including recently settled juveniles,
females and terminal males, of <EM>P</EM>. <EM>rubrizonatus</EM> were caught,
ranging in standard length (<EM>L</EM><SUB><FONT size=1>s</FONT></SUB>) from
16·9 to 96·5 mm. Presumed ages estimated from whole and sectioned otoliths
ranged between 22 days and 5 years, and parameter ±<SPAN
class=smallCaps>s.e.</SPAN> estimates of the von Bertalanffy growth model were
<EM>L</EM><SUB><FONT size=1>∞</FONT></SUB> = 152 ± 34 mm, <EM>k</EM> =
0·15(±0·05) and <EM>t</EM><SUB><FONT size=1>0</FONT></SUB> = −1·15(±0·15).
Estimated annual growth rates were similar between shallow and deep artificial
structures; however, otolith lengths and recent growth of juveniles differed
among individual structures, irrespective of depth. The artificial structures
therefore sustained full populations of <EM>P</EM>. <EM>rubrizonatus</EM>, from
recently settled juveniles through to adults; however, confirmation of the
maximum age attainable for the species is required from natural populations.
Depth placement of artificial reefs may not affect the production of fish
species with naturally wide depth ranges.</DIV></DIV></FONT><BR>
