DEVICE FOR vivo study in fish digestion process

摘要

The invention relates to the fishing industry, in particular to devices for studying the processes of digestion in fish. The object of the claimed utility model is to simplify the collection of the body decay products processed fish for in vivo study of the degree of digestibility of food items, the digestive processes. The objective is achieved by a device for in vivo study in fish digestive processes, consisting of a body in the form of a cylindrical tube and a tip made of corrugated material within the housing is placed a piston slidably movable along the longitudinal axis, and on the tip planted a ring elastic material, providing a tip diameter change. Furthermore, the housing is provided with a locking piston.
