A device for measuring co2 respiration metabolism of seawater fish, shrimp and shellfish

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...

AI Technical Summary

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
