Weight and width relationship of freshwater prawn ( Macrobrachium rosenbergii)

It has been shown that there is no significant difference (P < 0·05) in the weight = f (width) and orbit length = f (width) relationships of commercially produced male and female Macrobrachium rosenbergii in Hawaii. A regression equation of the form Ŷ = (A ∗ X ∗∗ B) ∗ ϵ has been shown to adequate...

Summary:It has been shown that there is no significant difference (P < 0·05) in the weight = f (width) and orbit length = f (width) relationships of commercially produced male and female Macrobrachium rosenbergii in Hawaii. A regression equation of the form Ŷ = (A ∗ X ∗∗ B) ∗ ϵ has been shown to adequately describe the above relationships. In particular Weight = 0·01278 ∗ (width) ∗∗ 2·5189, R ∗∗ 2 = 0·978 Orbit length = 0·1828 ∗ (width) ∗∗ 0·77685, R ∗∗ 2 = 0.996 This relationship allows the development of a simple mechanical prawn size sorter.
