Embodiment 1

[0035] Such as figure 1 As shown, this embodiment is used in conjunction with a device for measuring the respiratory and excretion of aquatic animals, and is applied to the auxiliary measurement of oxygen consumption and ammonia excretion of shrimp. Put a certain number of prawns of a certain size into the device, fill it with water, insert a dissolved oxygen probe (such as the DO / T sensor produced by WTW in Germany, TriOxmatic700 IQ type), turn on the submersible pump 6, and wait for the prawns to adapt to the device for a certain period of time Then, collect water samples from the thin plexiglass tube 7 through the rubber hose as the amount of ammonia nitrogen in the water before the experiment. After sampling, add water until all the exhaust air is full, seal the plastic cover 10, and read from the DO / T sensor. The oxygen consumption can be calculated, and the ammonia discharge can be obtained by comparing the water sample collected at the end of the experiment with the ammonia...

Embodiment 2

[0037] Such as figure 1 As shown, this embodiment is used in conjunction with a device for measuring the respiratory and excretion of aquatic animals, and is applied to the auxiliary measurement of oxygen consumption and ammonia excretion of sea cucumbers. Put a certain number of sea cucumbers of a certain size into the device, fill it with water, insert the DO / T sensor (TriOxmatic700IQ), turn on the submersible pump 6, and wait for the sea cucumbers to adapt to the device for a certain period of time, pass the soft rubber through the thin plexiglass tube 7 The water sample is collected by the tube as the amount of ammonia nitrogen in the water body before the experiment. After sampling, add water until all the exhaust air is full, seal the plastic cover 10, and calculate the oxygen consumption from the readings of the dissolved oxygen probe at the end of the experiment. Collect water samples at the end of the experiment The amount of ammonia discharged can be obtained by comparin...

Embodiment 3

[0039] Such as figure 1 As shown, this embodiment is used in conjunction with a device for measuring the respiratory and excretion of aquatic animals and is applied to the auxiliary measurement of oxygen consumption and ammonia excretion of scallops. Put a certain number of scallops of a certain size into the device, fill it with water, insert the DO / T sensor (TriOxmatic700IQ), turn on the submersible pump 6, and wait for the scallops to adapt to the device for a certain period of time, pass the soft rubber through the thin plexiglass tube 7 The water sample is collected by the tube as the amount of ammonia nitrogen in the water body before the experiment. After sampling, add water until all the exhaust air is full, seal the plastic cover 10, and calculate the oxygen consumption from the readings of the dissolved oxygen probe at the end of the experiment. Collect water samples at the end of the experiment The amount of ammonia discharged can be obtained by comparing the amount of ...

Abstract

The invention relates to a device used for matching with the measurement for respiration and excretion of aquatic animals, in particular to an attachment used for matching with various dissolved oxygen probes to measure the respiration and the excretion of various aquatic animals such as fish, shrimps as well as crabs, bivalve mollusks, sea cucumbers, etc. living in freshwater or seawater. The device takes an organic glass slab-bottom at the bottom of a crude organic glass tube as a back cover to form a vessel; a concentric-circle organic glass flange provided with holes is sleeved on the upper end of the crude organic glass tube at the height parallel to a nozzle; an organic glass cover plate is arranged on the top of the organic glass flange to be used as an upper cover; a fine organic glass tube and a PVE tube cuff are arranged on the organic glass cover plate; the PVE tube cuff is inserted into the dissolved oxygen probes in a sealing way; a diving pump is arranged under the PVE tube cuff. The device solves the problems that the prior art cannot reflect the metabolic status of the aquatic animals factually and accurately, etc., and has the advantages of simple structure, low manufacturing cost, being easy to match with correlated instruments to detect accurately, etc.

Description

Technical field: [0001] The invention relates to a device for measuring the respiratory and excretion of aquatic animals. Specifically, it can be used with various dissolved oxygen probes to measure fish, shrimps, crabs, and bivalves living in fresh water or seawater. And sea cucumber and other aquatic animals' respiratory and metabolism accessory devices. Background technique: [0002] At present, the research on the respiratory metabolism of various aquatic animals such as fish, shrimps and crabs, bivalves and sea cucumbers, that is, the technology of oxygen consumption and ammonia excretion, usually uses the aquatic animals to be placed in a jar or conical flask. Fill up the water and seal it with a rubber stopper or plastic film. After a certain period of time, open the stopper or remove the film. Collect a water sample to measure the amount of ammonia nitrogen and dissolved oxygen in the water. Compare with the data before the experiment to calculate the aquatic animal’s Oxy...
