摘要:Data collected during fishery-independent sampling programs were used to examine the
impact of appendage damage (indicated by lost or regenerated legs and antennae) on the
reproductive output of female western rock lobster (Panulirus cygnus). Most of the damaged
females sampled had one (53%), two (27%), or three (13%) appendages that had been lost or
that were regenerating. Appendage damage was associated with the reduced probability of a
female developing ovigerous setae; and if setae were produced, with the reduced probability
that females would produce more than one batch of eggs within a season. These effects were
more pronounced as the number of damaged appendages increased. From data collected in
2002, it was estimated that the total number of eggs produced by mature females caught in the
fishery was significantly reduced (P<0.001) by 3¨C9% when the impact of appendage damage
was included.
