A method for external fish parasite monitoring in aquaculture, comprising the steps of: - submerging a camera in a sea pen comprising fish; - capturing images of the fish with the camera; and - identifying external fish parasite on the fish by analyzing the captured images, characterized by the steps of: - distinguishing between at least two different classes of external fish parasite which differin the difficulty of recognizing the external fish parasite; - calculating quality metrics for each captured image, the quality metrics permit-ting to identify the classes of external fish parasite for which the quality of the image is sufficient for lice detection. 一种用于水产养殖中的鱼外部寄生虫监测的方法，其包括以下步骤：-将照相机浸没到包含鱼的海围栏中；-用所述照相机捕获所述鱼的图像；和-通过分析所捕获的图像来识别所述鱼上的鱼外部寄生虫，其特征在于以下步骤：-在至少两个不同类别的鱼外部寄生虫之间进行区分，其不同在于识别所述鱼外部寄生虫的难度；-对每个所捕获的图像计算质量指标，所述质量指标允许识别鱼外部寄生虫的类别，所述图像的质量为此足以用于虱子检测。
