The utility model discloses an embodiment's experimental activity picture peg fish bowl of using is measured according to following step:

1. cleaning the device, and properly rinsing with fishpond water.

2. Filling the tank body 1 with fish pond water, and continuously oxygenating the water body by using a small oxygenation pump; and opening a button of the temperature control base to set the temperature and the time.

3. Selecting a test object with proper specification, fishing and weighing the test object, then putting the test object into the tank body 1, filling the water in the fishpond for stabilization for 10min, and if data under a stress state needs to be measured, the data do not need to be stabilized.

4. Taking out the oxygenation pump, using an oxygen dissolving instrument to measure initial dissolved oxygen, immediately inserting the movable inserting plate 2, wherein the movable inserting plate 2 firstly passes through the first through hole 501, then passes through the first guide groove 301 and the second guide groove 302, and finally passes through the second through hole 502 and extends out of a part of the cylinder body 1; because the movable inserting plate 2 is parallel to the bottom surface and can be drawn and inserted in parallel to the bottom surface, the movable inserting plate can stably slide at the same water level and fully contact with the water surface, so that the water body in the cylinder body 1 is sealed, and the contact between the water surface and the air is blocked.

5. At present, the measurement of the water dissolved oxygen in the actual production generally uses an oxygen dissolving instrument with a cylindrical probe, and the probe 701 of the oxygen dissolving instrument is fixed on the central opening of the movable inserting plate 2 and is fixed by a rubber sleeve 4. Timing is started after the numerical value is stabilized to the initial dissolved oxygen, a time node is set to read data, the movable inserting plate 2 is slowly moved in the period, the probe 701 is driven to perform multipoint measurement at the same height, and the obtained data are more accurate and stable; and the data accuracy is ensured.

6. And setting a dissolved oxygen or time threshold value to stop the test, and calculating the respiration oxygen consumption rate of the test object through the water volume, time, fish weight and dissolved oxygen.

7. Control was set up and the experiment was repeated.

In actual production, the asphyxia point, critical dissolved oxygen, respiratory rate and oxygen consumption rate of aquatic animals of different varieties and specifications have obvious differences, generally speaking, the measurement of the physiological indexes needs a transparent, narrow and environmentally stable test space, and the required data comprises: water volume, time, water dissolved oxygen, and test subject weight. Therefore, the fish tank is required to be reasonable in size setting, the water volume is convenient to calculate, and the physiological characteristics of the experimental object are considered. Taking fish as an example, if the width of the rectangular fish tank is less than or equal to 2/3 of the body length of the rectangular fish tank, most species cannot complete turning-around action, so that the disturbance of the swimming of the fish tank to a water body can be reduced to the greatest extent, and the breathing times of the fish tank can be conveniently observed and recorded; however, in the common open fish tank, the water surface is in contact with the air, so once the test fish floats for many times, the accurate respiration oxygen consumption rate and the suffocation point cannot be measured. Therefore, the utility model designs a special movable plugboard of one layer on the basis of the original observation fish tank, and the plugboard fully contacts with the water surface to block the contact of the water surface and the air. At present, the measurement of water dissolved oxygen in actual production generally uses a dissolved oxygen meter with a cylindrical probe, so that a hole is formed in a movable inserting plate, and a rubber sleeve is installed on the movable inserting plate and used for fixing the probe of the dissolved oxygen meter; the inner wall of the cylinder body is provided with a guide groove at a specific height, so that the flashboard can stably slide at the same water level; the bottom of the cylinder body is provided with a temperature control base which can maintain the water temperature.

If the condition for directly measuring the weight of the test object is available, a separate weighing step can be omitted; if the test time is short, the temperature-controlled base can be removed. The criteria for determining the critical dissolved oxygen and the asphyxia point are not unified, but the critical dissolved oxygen and the asphyxia point can be determined by the operation of the device, so that only the suggestion of using the device to measure the respiratory oxygen consumption rate is given. The cylindrical probe dissolved oxygen meter generally has the additional function of measuring water temperature, can be compared with the temperature set by the temperature control base to be adjusted in time, and can be provided with a temperature sensor if the function of measuring the water temperature is not available. The module of the tank body refers to the body ruler of the edible carp, the crucian carp and the tilapia in the mature period, and the volume of the water body is set to 35cm multiplied by 20cm multiplied by 30cm multiplied by the length multiplied by the width multiplied by the height. In production, the module is set according to the actual specification of the cultured variety and then customized.

Development space: the volume of the experimental object can be measured by utilizing the volume of the overflowing water, so that the weight of the experimental object is estimated, the experimental object can be prevented from being weighed when the precision requirement is not high, and therefore, drainage design is carried out on the side wall, and the liquid can be conveniently collected and the volume can be conveniently measured. Manual to automatic conversion, i.e. sliding is completed by a motor; data automatic collection, namely setting time nodes for automatic calculation and recording; and video recording, namely recording the breathing frequency, the floating head action and the like of the test object by a sensor and an identification system.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
