Shellfish energy budget in-situ measuring device

Abstract

The invention provides a shellfish energy budget in-situ measuring device. The shellfish energy budget in-situ measuring device is characterized in that a shellfish culture box is arranged in a sealed cabinet and comprises a culture chamber, the upper portion of the culture chamber is a cylinder, and the lower portion of the culture chamber is a cone; a water inlet chamber and a water outlet chamber are arranged on the outer side of the cylinder; a shellfish separation net is arranged in the cylinder horizontally, a shellfish excrement sample outlet pipe orifice is arranged at the bottom of the culture chamber, a sample bottle turnplate driven by a stepping motor is arranged below the culture chamber, and the stepping motor is connected to a controller; sensors are mounted on the side walls of the water inlet chamber and the water outlet chamber respectively, are connected with the controller and are powered by battery packs. The shellfish energy budget in-situ measuring device has the advantages that an actual shellfish culture environment is simulated, automatic disturbance-free high-frequency detection of shellfishes in the whole experiment period can be achieved, and parameters of a shellfish culture water area are acquired automatically, so that workload of researchers is lowered greatly, experimental results are real and accurate, and the reliable basis is provided for accurate evaluation of energy budget and scientific culture of the shellfishes.

Description

technical field [0001] The invention belongs to the technical field of aquaculture equipment, and relates to a shellfish culture detection device, in particular to an in-situ detector for shellfish energy balance. Background technique [0002] With the rapid development of offshore shellfish farming, how to correctly determine the scale and type of shellfish farming is the key to the success of shellfish farming. The energy budget of shellfish is an important part of the study of shellfish physiology and ecology. Important parameter for capacity assessment. [0003] The energy budget of shellfish refers to the changes in dissolved oxygen, ammonia nitrogen, temperature, salinity and chlorophyll a in shellfish culture waters, and evaluates the oxygen consumption rate, excretion rate, feeding rate and other indicators of shellfish during the breeding process. [0004] At present, the determination of the energy budget of shellfish is mostly carried out by the measurement of re...

Problems solved by technology

Sealed bottles are usually replaced by jars and rubber stoppers, and the breathing chamber is made of plastic film. This method is easy to obtain and easy to operate, but its disadvantages are very obvious: (1) poor sealing; (2) test shellfish are easily disturbed ; (3) Feed organisms and feces samples cannot be collected at any time; (4) The simulated breeding environment is quite different from the actual breeding environment; (5) It is difficult to conduct experiments for a long time

The above problems lead to a large error in the measurement
