The Malaysian giant prawn, Macrobrachium rosenbergii, is an important crustacean aquaculture candidate cultured all year round in hot climate regions and seasonally in some temperate areas. According to the authors 'knowledge, there is no reported multiple -approach attempt so far, at least for shrimps, for estimating weight using morphometric measurements. The authors hypothesized that the few morphometric traits, with proved simple significant relationships, are expected to affect body weight simultaneously. Hence, in this study they decided to use a multiple approach using these morphometric measurements as predictors for body weight. The approach was found to be more effective and accurate compared to simple relations, as it explained 73- 94% of the total variance and showed significant differences between populations of the species collected from different geographical locations. Accordingly, the authors confidently recommend this method to be used for such estimations in other crustaceans and another metazoan as well
