Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an automation method of viability, molting confirmation and harvest propriety determination in shell-fish aquaculture using a data processing technique with respect to the shell-fish received individually and cultured.SOLUTION: An automation method of viability, molting confirmation and harvest propriety determination in shell-fish is characterized by: monitoring the shell-fish received individually and cultured using an image acquisition device and capturing a still image at regular time intervals; storing data concerning sizes, areas and center of gravity position of the shell-fish calculated by image processing in a memory device; and comparing the stored data with the data calculated from the monitoring image added at regular time intervals.SELECTED DRAWING: Figure 5 【課題】個別収容して養殖する甲殻類に対し、情報処理技術により生死判別、脱皮確認、収穫適否判定を自動化する方法の提供。【解決手段】個別収容して養殖する甲殻類を画像取得装置により監視して一定時間ごとに静止画像を取り込み、画像処理によって算出した該甲殻類の寸法、面積、重心位置データを記憶装置中に保存し、この保存データと一定時間ごとに追加される監視画像から算出されるデータとを比較することによって、該甲殻類の生死判別、脱皮確認、収穫適否判断を自動化する。【選択図】図５
