Apologies for cross-postings.

Dear listers,

I am attempting to estimate biomass from visual estimates of abundance and length for reef fishes in Palau.  I have been unable to find information on length-weight relationships for the following species:

Bolbometpon muricatum (bumphead parrotfish)
Cetoscarus bicolor (bicolor parrotfish)
Hipposcarus longiceps (Pacific longnose parrotfish)
Plectropomus areolatus (squaretailed coralgrouper)
Plectropomus laevis (giant coralgrouper)

I have checked FishBase but no luck there.  If anyone can supply me with a length-weight regression for these species, I would be eternally grateful!
