中文摘要:针对循环水养殖游泳型鱼类过程中的高效投喂难题进行了研究,以罗非鱼为实验对象,提出了一种基于改进动能模型的鱼群摄食活动强度评估方法。该方法避免了鱼群目标的前景提取和对鱼群内个体的跟踪,直接以由鱼群摄食活动引起的水面反光区域变化特征为关键因素进行分析。首先,在HSV色彩空间下对水面反光区域进行分割、提取;其次,利用Lucas-Kanade光流、统计学方法以及信息熵对反光区域变化的不规律程度进行计算和分析;最后,结合反光区域的变化幅度信息实现对鱼群摄食活动强度的评估。通过实验结果对比分析可知,所提方法在单轮多次饱食投喂(间隔时间(40±2)s)下针对不同肠胃饱满指数(20.35±10、150.61±10)的罗非鱼均能较好地描述鱼群摄食活动强度。

Abstract:The problem of effective feeding for swimming fishes in recirculating aquaculture system (RAS) was studied. In order to solve this problem, a novel assessing method for the feeding activity of shoal was proposed with the help of tilapia which was used as the experimental objective, and the proposed method was based on the improved kinetic energy model. Instead of the complex segmentation of foreground of shoal and the tracking of individuals among shoals, the change characteristics of reflective areas of water surface caused by feeding activity of shoal were regarded directly as the key factor in this method. Firstly, the reflective areas of water surface were segmented and extracted in HSV-based color space. Then, with the help of the Lucas-Kanade optical flow, statistics method and entropy, the disorder degree of the change in reflective areas was calculated and analyzed. Finally, combined with information of the changing magnitude of reflection areas, the intensity assessment of feeding activity of shoal was executed. According to the comparison and analysis of the experimental results, the proposed method showed good description in intensity of feeding activity of shoal with different digesta index of stomach and bowels (20.35±10, 150.61±10) under strategy of over-satiation feeding through intermittent feeding at intervals of (40±2) s.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
