Miniature Fish Respirometry System with Integrated Cameras

Master's thesis in Mechatronics (MAS500) A respirometry system for small fish up to 30 mm in length has been developed and a prototype has been produced to verify the design. The developed system has two integrated cameras for top and side filming of the specimen during testing. The report details the development of an axial impeller pump based on a theoretical pump head loss analysis of the system and max flow velocity of 20 cm/s. A PI regulator has been implemented to accurately control the rotational velocity of the impeller. Control software for the operation of the respirometry system has been conceptualized and partly implemented.
