11 581 Þshes were estimated to have recruited as larvae to
the bommies. The number of post-recruit immigrants was
estimated to be 10 994 when the least conservative sample
error value (DxÐmean) was used to estimate post-recruit
immigration, and 7320 when the more conservative value
(Dx99.9) was used (Eq. 2). Therefore, post-recruit immigrants
accounted for at least one third of the total inßux of
new Þshes to the bommies.
There were signiÞcant di¤erences between bommies in
the total number of recruits and post-recruit immigrants
