Última Experimental study of filtration activity in Ditrupa arietina (Annelida Polychaeta) using an automated image analysis system ArchiMer Duchene, Jean Claude; Jordana, Esther; Charles, François; Gremare, Antoine; Amouroux, Jean Michel. An automated image analysis system designed to assess the activity of benthic organisms is described. This system is used to study filtration in the serpulid polychaete Ditrupa arietina. The video sensor of the system is composed of a black and white charged coupled device, a microprocessor, a memory and an interface board. It is driven by real-time routines, which are downloaded in permanent memory prior to each experiment. These routines control picture acquisition frequency and compute the differences in grey levels between the image recorded at a given time and a reference image (corresponding to no filtration in the case of D. arietina). These differences are used to detect numerical objects, which are stored in the memory board. At the end of each...

SYBIOL, SYstem of BIOmetry of Larvae by image analysis, has been designed for measuring larvae of bivalves in a semi automatic way. The main interest of this tool is to provide more information with the extraction of parameters such as area or equivalent diameter. Our purposes are to describe and evaluate the system which is now operational and used in routine in the mollusc hatchery of Argenton.
