Abstract
Approximate weights offish were calculated from length and width measurements of their photographic images. In the calculations we employed the formula Wt = KLW², where Wt = weight (g); K = proportionality factor, derived from a subsample of the population under study; L = length (cm); and W = width (cm). When tested against true weights, the derived weights had a mean error of ±8.6%.Keywords
