  abstract = {{M}ost studies involving {P}acific reef fishes use underwater visual censusing techniques to estimate their biomass and stock. {T}his requires to know the length-weight relationships of all the species censused. {C}urrently, only a,p portion of these relationships (15.4%) are available for reef fish species in the {P}acific area. {I}n the present article small we propose length-weight relationships at four organisation levels: species, genera, families and morphological groups. {A} data base of 53,800 specimens belonging to 788 species from {N}ew {C}aledonia were used to estimate the relationships for 396 species, 185 genera, 75 families. {A}t the genus level, the length-weight relationships cover 76% of the {P}acific reef species and the coverage is nearly 85% at the family level. {A} study of the morphology of 1,100 specimens belonging to 311 species allowed to define 30 morphological groups, for which length-weight relationships were then estimated using 32,551 specimens belonging to these species. {U}sing 3 classes of body thickness, a second clustering of these species defined 20 groups allowing length-weight relationships to be estimated from 2{D} pictures. {T}hese relationships allow to estimate weight from length data for most of the species not covered by the relationships at the species, genus or family level. {T}he error levels increase from the species (average error 9.4%) to the family level (13.5%), the morphological groups yielding errors equivalent to those from the family level equations (13.2%). {A} graphical analysis of the coefficients from 396 length-weight relationships suggests that there are physical limits to fish shapes.},
