Problems solved by technology

Due to the measurement of CO 2 The specificity of respiratory metabolism, in this process, when the water sample is taken after opening the rubber stopper or removing the film, the CO in the air 2 Will dissolve into the experimental water, and then make the measured CO 2 The amount of respiratory metabolism increases, which eventually leads to wrong results, which cannot truly and accurately reflect the metabolism of aquatic animals
Foreign countries have developed a variety of accurate measurement of CO in water 2 Probes for respiratory metabolism, including on-line and hand-held measuring instruments, etc. However, for the measurement of larger or adult aquatic animals, often due to volume reasons, there has been a lack of relevant CO 2 Respiratory Metabolism Test Device

example 1

[0021] The present invention is applied to the CO of prawns 2 Auxiliary measurement of respiratory metabolism. Put 50 to 100 vannamei shrimps with a tail body length of 8 to 11 cm into the device, add appropriate amount of water, insert the corresponding carbon dioxide probe 4, turn on the submersible pump 14, and add oxygen to the device through the air line 9 at the same time, and wait for the shrimp to After adapting to the device for a certain period of time, stop the oxygen supply, slowly replenish water from the vent valve 6 until all the air is exhausted, seal the upper cover 10, and record the reading of the carbon dioxide probe 4 at the same time, and the reading of the oxygen probe 5 drops to 5mg / L Record the reading of the carbon dioxide probe 4 again, and the CO2 can be calculated from the beginning and end readings of the carbon dioxide probe 4. 2 metabolic rate.

Embodiment 2

[0023] The present invention is applied to the CO of fish 2 Auxiliary measurement of respiratory metabolism. Put 10-15 puffer fish with a weight of 100-150g into the device, add appropriate amount of water, insert the corresponding carbon dioxide probe 4, turn on the submersible pump 14, and add oxygen to the device through the air pipeline 9 at the same time, and wait for the puffer fish to adapt to the device. After a certain time, stop the oxygen supply, slowly add water from the vent valve 6 until all the air is exhausted, seal the upper cover 10, and record the reading of the carbon dioxide probe 4 at the same time, and record the carbon dioxide probe again when the reading of the oxygen probe 5 drops to 4mg / L 4 readings, the CO can be calculated from the beginning and end readings of the carbon dioxide probe 4 2 metabolic rate.

Embodiment 3

[0025] The present invention is applied to the CO of scallop 2 Auxiliary measurement of respiratory metabolism. Put 100 to 150 scallops with a shell length of 5 to 7 cm into the device, and at the same time add oxygen to the device through the air pipeline 9, and after the scallops adapt to the device for a certain period of time, stop the oxygen supply and slowly replenish from the vent valve 6 Water until the air is completely exhausted, seal the upper cover 10, and record the reading of the carbon dioxide probe 4 at the same time, and record the reading of the carbon dioxide probe 4 after the reading of the oxygen probe 5 drops to 5 mg / L, and calculate from the beginning and end of the reading of the carbon dioxide probe 4 CO 2 metabolic rate.

Abstract

The invention relates to an auxiliary device for measuring aquatic animal breathing and excretion, in particular to a device for measuring seawater fish, shrimp and shellfish CO2 respiratory metabolism in a matched mode. The device comprises a carbon dioxide probe, an oxygen probe, a snuffle valve, an aerator pipeline, an upper cover, a bottle body and an immersible pump, wherein the immersible pump is arranged in the bottle body, the upper cover is arranged at the upper end of the bottle body and provided with a plurality of through holes, the carbon dioxide probe, the oxygen probe, the snuffle valve and the aerator pipeline, are inserted into the through holes of the upper cover respectively, the end, inserted into the bottle body, of the aerator pipeline is connected with a water inlet pipe of the immersible pump, and a water outlet pipe of the immersible pump is located below the oxygen probe. The device can meet requirements for measuring respiratory metabolism of adult aquatic animals and large aquatic animals under high-density conditions, solves the problem of lack of instrument auxiliary devices , and provides a very good scientific research platform for scientific workers.

Description

Technical field: [0001] The invention relates to an auxiliary device for measuring the respiration and excretion of aquatic animals, in particular to an auxiliary device for cooperating with measuring the CO of seawater fish, shrimp and shellfish. 2 Device for respiratory metabolism, used to cooperate with various CO 2 Probe to measure the CO of various animals such as fish, shrimps and crabs, bivalve molluscs, etc. living in seawater 2 respiratory metabolism. Background technique [0002] At present, research on the CO of fish, shrimps and crabs, bivalve molluscs, etc. 2 Respiratory metabolism, there is no special device and related technology, usually put the aquatic animal into a jar or Erlenmeyer bottle, fill it with water, seal it with a rubber stopper or plastic film, after a certain period of time, open the stopper Or remove the film to collect water samples to measure CO in the water body 2 Dissolved amount, by comparing with the data before the experiment, the C...
