Metabolism physiological measurement system and method for marine organisms

Abstract

The invention provides a metabolism physiological measurement system for marine organisms. The metabolism physiological measurement system comprises a water bath tank, a water pump, a splitter, breathing bottles, a water level control pipe, a multichannel dissolved oxygen determinator and a computer control system. According to the metabolism physiological measurement system for the marine organisms, disclosed by the invention, the opening time and the closing time of multiple groups of the breathing bottles are freely controlled under the condition of water bath of on-site water temperature, the accurate control of metabolism physiological experimental conditions such as oxygen consumption and ammonia excretion is realized, a computer acquires the dynamic changes of dissolved oxygen in a real-time manner through optical fiber dissolved oxygen sensors assembled on the breathing bottles, and key physiological metabolism parameters such as an oxygen consumption rate and an ammonia excretion rate are accurately determined.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a system for measuring the metabolism and physiology of marine organisms, and also relates to a method for measuring the metabolism and physiology of marine organisms. Background technique [0002] Metabolic physiology is one of the important contents of bioenergetics research. By studying the metabolic physiology of organisms and their interrelationships and changes with various biotic and abiotic factors, we can grasp the metabolic characteristics, physiological conditions, nutritional requirements and their effects on organisms. Adaptability to external environmental conditions and acceptable thresholds, etc., so as to provide data support for water resources assessment, water environment regulation, and breeding capacity model construction. [0003] At present, the research method of metabolic physiology is mainly the closed method. After putting the experimental organisms in...

AI Technical Summary

Problems solved by technology

[0004] 1. The experimental container is generally relatively small, which is easy to cause stress to the experimental organisms, and the experimental conditions are easily affected by the temperature;

[0005] 2. The time for the cultured organisms to adapt to the experimental conditions is short or even non-existent. During the test period, the experimental organisms are not in a normal physiological state, and the experimental results cannot reflect the actual metabolic state;

[0006] 3. The experimental results only have initial and end data, and the process changes during the experiment cannot be obtained
