Description

TECHNICAL FIELD

[0001] The present application relates to the field of water purification / aquaculture technology, in particular to a breeding pond breeding environment improvement system and method. BACKGROUND

[0002] During the breeding process of a breeding pond, due to the continuous accumulation of fish and shrimp excrement, dead bodies, organic fertilizers and residual feed, a thick layer of sludge will be formed on the bottom of the pond. At the same time, in order to ensure the healthy growth of fish, workers tend to overfeed, which further deposits residual feed on the bottom and aggravates pollution, eventually causing the bottom of the pond to be hardened. The bottom hardening of the pond has the following hazards:

[0003] Water hypoxia: The organic matter (such as residual feed, feces, dead algae, etc.) on the bottom of the pond will consume a large amount of oxygen during microbial decomposition, resulting in a significant decrease in dissolved oxygen in the bottom water, causing water hypoxia.

[0004] Impact: Under hypoxic conditions, fish grow slowly, immunity decreases, and diseases are easily triggered. In severe cases, it may appear as a floating head phenomenon, or even die from turning over the pond.

[0005] Water acidification: Organic matter is fermented and decomposed in anoxic environment, producing a large amount of organic acid and inorganic acid, resulting in acidification of the bottom and water, and a significant decrease in pH value.

[0006] Impact: Low pH value will affect the respiration and metabolism of fish, shrimp and crab, and growth will be stagnant or even death.

[0007] Large number of harmful bacteria: The harmful substances such as ammonia nitrogen and nitrite produced by the decomposition of organic matter provide a rich source of nutrition for harmful bacteria, promoting their rapid reproduction.

[0008] Impact: The increase of harmful bacteria will cause fish, shrimp and crab to get sick, especially for bottom-dwelling shrimp and crab, which will increase the risk of disease and mortality during the breeding process.

[0009] Production of toxic gases: In anoxic environment, anaerobic bacteria decompose organic matter to produce toxic gases such as ammonia, hydrogen sulfide and methane.

[0010] Impact: These gases have a direct toxic effect on aquatic organisms, affecting their normal physiological functions and survival.

[0011] Deterioration of water quality: The bottom hardening leads to an increase in suspended and colloidal matter in the water, reducing transparency and affecting the photosynthesis of phytoplankton and water stability.

[0012] Impact: Deterioration of water quality will further exacerbate the problem of insufficient dissolved oxygen, forming a vicious cycle, which will seriously affect the breeding efficiency and product quality.

[0013] Increased feed coefficient: bottom hypoxia leads to reduced fish feeding, reduced digestion rate and decreased feed utilization.

[0014] Impact: rising cost of aquaculture, reduced economic benefits, and residual feed that is not eaten will further aggravate the pollution of the bottom.

[0015] In summary, the existing aquaculture ponds have many problems such as pond bottom hardening and water eutrophication, which not only threaten the health and growth of aquatic animals, but also directly affect the economic benefits of aquaculture. Therefore, it is crucial to take effective measures to improve the aquaculture environment in time to ensure the success of aquaculture.
