Problems solved by technology

However, due to the interaction between biological communities and individuals of cultured organisms in the environment where the cultured organisms live, the assessment of the impact of shellfish on the ecosystem is not a simple superposition of individual-level research results. Large biases when rolled out to the entire ecosystem

Embodiment 1

[0033] Such as figure 1 , 2 As shown, the marine shellfish biophysiological experiment device based on the community level of the present embodiment includes a transparent upper barrel body 1, a funnel 2, a support barrel body 3 and a collection bottle 4, and the upper end of the funnel 2 is connected to a transparent The lower part of the upper barrel body 1, the support barrel body 3 is connected to the lower part of the transparent upper barrel body 1 through the first flange 5, the top of the transparent upper barrel body 1 is connected to the sealing cover 11 through the second flange 6, and the transparent upper barrel body 1 The inside is provided with the inner hanging pole 12 that is used for suspending the experimental biological community, and one or more groups of biological communities can be suspended on the inner hanging pole 12, and one group or multiple groups of experiments can be carried out simultaneously. Different marine shellfish biomes can be hung in d...

Embodiment 2

[0045] Such as image 3 As shown, the biological physiological experiment method of marine shellfish based on the community level of the present embodiment comprises the following steps:

[0046] S1: Suspend the experimental biological community on the inner hanging rod, the water inlet is connected to the water pump for water supply, the water control valve controls the water intake, and selectively opens or closes the two water outlets to simulate the flow speed of seawater, in order to ensure the water flow in the barrel Mix well, and open the upper water outlet preferentially;

[0047] S2: After the experimental biological community adapts to the running water state for 1-2h, the collection bottle is emptied, and the physiological experiment of feeding begins; the experiment lasts for 10-12h, and the content of suspended particulate matter and particulate organic matter in the water inlet is measured every 3h; after the experiment is over, the Empty the seawater in the ba...

Abstract

The invention relates to the technical field of physiological experiments of marine organisms, in particular to a physiological marine shellfish organism experiment device based on community level and a usage method thereof. The experiment device comprises an upper transparent bucket, a funnel, a supporting bucket and a collecting bottle, wherein a sealing cap is arranged at the top of the upper transparent bucket, an inner hanging rod for hanging an experiment biocenosis is arranged in the upper transparent bucket, one side bucket wall is provided with a water inlet and is externally connected with a water pump and a water control valve, and the other side bucket wall is provided with a water outlet. The middle of the supporting bucket is provided with a cylindrical opening, the collecting bottle is placed in the cylindrical opening, and a lower end pipe of the funnel extends into the collecting bottle. Natural seawater temperature, flowing speed and other conditions are simulated through the experiment device, physiological experiments about ingestion and metabolism of the marine shellfish biocenosis are performed by utilizing the large-volume container, experiment links are decreased, and errors existing when biont experiment results are popularized to the whole ecological system are avoided while biocenosis wholeness is kept.

Description

technical field [0001] The invention relates to the technical field of marine biological physiological experiments, in particular to a marine shellfish biological physiological experimental device and experimental method based on a community level. Background technique [0002] Marine filter-feeding shellfish is an important part of the structure of biological resources in marine ecosystems. Research on the physiological energy of shellfish feeding, assimilation, respiration, and excretion can provide necessary data support for evaluating the breeding capacity of sea areas. The role and function of shellfish in aquatic ecosystems have important theoretical significance. [0003] At present, the research methods of feeding and metabolic physiology of filter-feeding molluscs mainly include static water method and simulated field flow tank method, and the research level is mainly based on the individual level. The static water method mainly uses a certain volume of container, ...
