Spiny lobster growth as an indicator

Thanks all of you for your timely and influential responses.  I also
concur  that perhaps this idea needs to be looked at again.  It was not
mine originally and that is why I asked for your help.  On the other
hand, Im am involved in research that is focusing on several areas
except health, and I did want to include something where we could get
some indication of the overall health of the reef system we are involved
with.  There are numerous methods I would suppose-censusing known
corrallivores for example, but we are limited as to what we can do due
to both depth and bottom times.  This is a Carribean reef and the
average depth of our transect stations is 100'.  Again, suggestions are
welcomed.  One idea that I did have was the mark and recapture of
juvenile fishes using traps.  Pomacentrids, I think, stick pretty much
to their home reef sites and never ventrue very far away as do other
less mobile species.  Of course the presence or non-presence of coral
diseases is something else we could look at.  But determining that from
a 60X4 meter transect using video for example, is that really an
indication of overall health?  You folks are the experts and Im just a
techinician with a real interest.  Thanks
