This study developed a linear regression model to
predict the occurrence of cannibalism in larviculture of orange-spotted
grouper, Epinephelus coioides. Based on measurements of mouth width
(MW), body depth (BD), and total length (TL), a model of prey length (mm) to
cannibal length was constructed: TLprey=0.80 TLcannibal-1.50.
According to the equation, we suggest that 30% is a threshold for TL
differences to use in grading grouper fry, and that beyond the threshold,
potential cannibals should be removed.
