Abstract

L'invention concerne un procédé d'estimation de la longueur corporelle et du poids d'une crevette sur la base du diamètre d'un globe oculaire de celle-ci, dans lequel une image d'un globe oculaire d'une crevette est acquise, des données du diamètre du globe oculaire de la crevette sont obtenues avec précision au moyen d'une analyse logicielle, et des données de la longueur corporelle et du poids de la crevette peuvent être déterminées avec précision en fonction d'un modèle d'ajustement du diamètre d'un globe oculaire et d'une longueur corporelle, ainsi que d'un modèle d'ajustement du diamètre d'un globe oculaire et d'un poids. Le coefficient de corrélation entre le diamètre d'un globe oculaire et le poids d'une crevette, qui est mesuré au moyen du présent procédé, est équivalent au coefficient de corrélation entre une longueur corporelle et un poids, et le globe oculaire d'une crevette peut devenir autofluorescent dans une condition de lumière faible, facilitant la reconnaissance d'image par un ordinateur, afin de réaliser une surveillance automatisée.
