Description

Collection device for aquaculture

Technical Field

The utility model belongs to the technical field of collection device, concretely relates to collection device for aquaculture.

Background

The research on the nutrition of the aquatic animals plays an important role in promoting the aquaculture, saving the aquaculture cost and the like. The food intake and the content of nutrient elements in the excrement are two basic indexes of fish nutrition research. The important link in the food intake statistics is the residual bait amount statistics. However, since aquatic animals live in water bodies, collection of residual baits is difficult, which has been a major concern of experts in the related art. Similarly, since the feces of aquatic animals are easily dispersed in the water, it is not practical to analyze the whole water, so how to collect the feces in the water to the maximum is another concern of aquatic animal nutrition experts.

At present, the fishing method can be used for collecting residual baits for aquatic animals which eat buoyant feeds, but for aquatic animals which eat sinking baits, the main method is to collect residual baits according to the siphon principle at present. This includes manual aspiration using a pipette or aspiration with a small instrument. In both methods, the suction pipe at one end of the water inlet pipe needs to be moved ceaselessly, so that the normal movement and physiological activity of the experimental aquatic animals are seriously interfered, and the accuracy of some experiments is further influenced; meanwhile, the siphon method also has the problem that the residual bait is not sufficiently collected and cannot meet the experimental requirements. In addition, the method for manually fishing the sinking residual baits is recommended to be not used due to large workload and great human errors.
