Abstract

The invention provides an oxygen consumption rate and choke point measuring device of fishes, and relates to a device for measuring oxygen consumption rate and choke point of the fishes. The invention aims to solve the problems that a special device for measuring the choke point of the fishes is lacked, and the existing oxygen consumption rate and choke point of the fishes cannot be measured in the same device by an iodometry method. A respiratory chamber of the device is of a cylinder structure; a cover plate is arranged at an opening end of the respiratory chamber; a water outlet pipe is arranged on the cover plate; a water outlet valve is formed on the water outlet pipe; an axis, vertical to the cylinder, of a pushing plate is arranged in the respiratory chamber; screw threads are formed at the external surface of a water inlet pipe; one end of the water inlet pipe is fixedly connected with the pushing plate, and the other end of the water inlet pipe is in threaded connection with a nut after penetrating through a closed end of the respiratory chamber; the nuts are in embedded connection with the external wall of the respiratory chamber; a water inlet communicated with the water inlet pipe is formed in the pushing plate; a water inlet valve is formed on the water inlet pipe; one end of a round bar is fixedly connected with the pushing plate, and the other end of the round bar penetrates through the closed end of the respiratory chamber. The device is used for measuring the oxygen consumption rate and choke point of the fishes.

Description

technical field [0001] The invention relates to a measuring device, in particular to a device for measuring the oxygen consumption rate and suffocation point of fish, and belongs to the field of aquatic products. Background technique [0002] Fish are temperature-changing animals, and the temperature of the water environment directly affects the body temperature of the fish, which in turn affects the activity of enzymes and the biological oxidation reactions catalyzed by enzymes. These metabolic activities are related to the utilization of oxygen. Therefore, the oxygen consumption rate and suffocation point of fish directly or indirectly reflect the physiological and living conditions of fish under the influence of external conditions. Circulation, energy flow, breeding capacity, etc. are of great significance, and provide scientific basis for fish farming production, water quality control, bait utilization, and live fish transportation. [0003] The measurement of the exis...
