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] like figure 1 , 2 As shown, the marine shellfish biological physiological experimental device based on the community level of this embodiment includes a transparent upper barrel 1, a funnel 2, a supporting barrel 3 and a collection bottle 4. The upper end of the funnel 2 is connected to the transparent The lower part of the upper barrel 1, the supporting barrel 3 is connected to the lower part of the transparent upper barrel 1 through the first flange 5, the top of the transparent upper barrel 1 is connected to the sealing cover 11 through the second flange 6, and the transparent upper barrel 1 The interior is provided with an inner hanging rod 12 for suspending experimental biological communities, and one or more groups of biological communities can be suspended on the inner hanging rod 12, and one or more groups of experiments can be carried out at the same time. Different marine shellfish biomes can be hung in different ways, such as mussels, oysters and other biome...

Embodiment 2

[0045] like image 3 As shown, the marine shellfish biological physiological experimental method based on the community level of this embodiment includes the following steps:

[0046] S1: Suspend the experimental biological community on the inner hanging rod, connect the water pump to the water inlet to supply water, the water control valve controls the amount of water inflow, 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 Fully mix, give priority to opening the upper water outlet;

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

Abstract

The invention relates to the technical field of marine biological physiological experiments, in particular to a marine shellfish biological physiological experimental device based on a community level and a method for using the same. The experimental device includes a transparent upper barrel, a funnel, a supporting barrel and a collection bottle. The top of the body is provided with a sealing cover, and the interior is provided with an internal hanging rod for suspending the experimental biological community. One side of the barrel is provided with a water inlet, an external water pump and a water control valve, and the other side of the barrel is provided with a water outlet; supporting the barrel The middle part of the funnel is provided with a cylindrical mouth, a collection bottle is placed in the cylindrical mouth, and the lower end tube of the funnel extends into the collection bottle. The invention simulates the natural seawater temperature, flow rate and other conditions through the experimental device, and uses a large-volume container to carry out the feeding physiological experiment and the metabolic physiological experiment of the marine shellfish biological community, thereby reducing the experimental link, while maintaining the integrity of the biological community. Errors in the generalization of experimental results to the entire ecosystem.

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 an experimental method based on a community level. Background technique [0002] Marine filter-feeding shellfish is an important part of the biological resource structure in the marine ecosystem. The study of the physiological energetics of shellfish feeding, assimilation, respiration, excretion, etc., can provide necessary data support for evaluating the aquaculture capacity of the sea area. 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 shellfish mainly include hydrostatic method and simulated field flow tank method, and the research level is mainly based on the individual level. The hydrostatic method mainly uses a container of a...
