Scientific Application and Practical Guide of Potassium Fulvate in Aquaculture

In the context of aquaculture transforming towards green, efficient, and ecological development, potassium fulvate, with its combined advantages of small-molecule organic carbon, active functional groups, and rich trace elements, has become a multi-functional green input for water regulation, sediment improvement, algae stabilization, seedling protection, and efficiency enhancement. It is widely applicable to various models such as fish, shrimp, crab, and shellfish farming, as well as industrial and pond aquaculture, effectively addressing pain points in high-density aquaculture such as water quality deterioration, sediment corruption, stress-related diseases, and low feed utilization rate.

I. Core Functions and Mechanisms: Full-Chain Empowerment from Water Body to Organism

(1) Water Quality Regulation: Stabilizing Water, Detoxifying, and Reducing Hazards

Potassium fulvate can quickly supplement small-molecule organic carbon in the water body, optimize the carbon-nitrogen ratio (C/N), activate heterotrophic microbial communities, efficiently degrade toxic substances such as ammonia nitrogen, nitrite, and hydrogen sulfide, stabilize pH value, and reduce the risk of sudden water quality changes. Its complexing ability can adsorb heavy metals, algal toxins, and pesticide residues, reducing environmental toxicity; at the same time, it improves the buffering capacity of the water body, avoiding sudden problems such as algal bloom collapse, sediment suspension, and oxygen deficiency, thereby creating a stable living environment for aquaculture organisms.

(2) Sediment Improvement: Loosening, Decomposing, and Inhibiting Bacteria

As a sediment improver, potassium fulvate can penetrate the pond bottom, loosen compacted sediment, enhance sediment permeability, accelerate the decomposition and transformation of residual feed, feces, and humus, and reduce anaerobic fermentation and blackening and odor of sediment. By inhibiting the reproduction of harmful bacteria (Vibrio, Aeromonas) at the bottom, it reduces the disease risks caused by sediment corruption, minimizes water pollution from the source, and realizes the aquaculture logic of "good sediment ensures good water quality".

(3) Algal Phase Balance: Cultivating Beneficial Algae and Inhibiting Harmful Algae

With high-quality carbon sources, potassium, and trace elements as nutrients, it directionally promotes the reproduction of beneficial algae such as diatoms and green algae, constructs a stable algal phase, increases dissolved oxygen in the water body, and provides natural biological bait. At the same time, it reduces water transparency through appropriate light shielding, inhibits the growth of harmful algae such as moss, mud skin, and cyanobacteria, avoids water bloom and oxygen deficiency caused by algal phase imbalance, and keeps the water color fertile, lively, tender, and refreshing for a long time.

(4) Organism Health Care: Enhancing Immunity, Promoting Digestion, and Resisting Stress

For aquaculture animals such as fish, shrimp, and crabs, potassium fulvate can activate the activity of immune cells, improve disease resistance, and assist in preventing and controlling common diseases such as Vibrio and enteritis; improve the intestinal microecology, promote the secretion of digestive enzymes, increase feed conversion rate, and reduce feed coefficient; regulate the osmotic pressure of the organism, alleviate stress responses such as sudden temperature changes, water exchange, transportation, and netting, improve seedling survival rate and growth rate, and also have the effects of protecting the liver and gallbladder and accelerating metabolism.

II. Scenario-Specific Practical Usage: Precise Application for Maximum Effect

(1) Routine Water Regulation and Stabilization

• Dosage: 0.5–1.0 kg per mu per meter of water depth, once every 10–15 days

• Usage: Fully dissolve in advance and sprinkle evenly across the entire pond

• Application: Water quality maintenance throughout the aquaculture process, stabilizing algal and bacterial phases, and preventing water quality deterioration

(2) Sediment Improvement and Detoxification

• Dosage: 1.0–2.0 kg per mu per meter of water depth

• Usage: After dissolving, focus on sprinkling around the pond bottom and feeding platforms

• Application: High-temperature period, middle and late stages of aquaculture, when sediment turns black and odorous, or when ammonia nitrogen and nitrite exceed the standard

(3) Low-Temperature Water Fertilization and Moss Inhibition

• Dosage: 1.0–1.5 kg per mu per meter of water depth, can be increased to 2.0 kg if moss infestation is severe

• Usage: Sprinkle across the entire pond, and reapply once every 3–5 days according to water color

• Application: Low-temperature water fertilization in early spring, moss prevention and control, aquatic plant maintenance, improving water fertility and heat retention

(4) Stress Resistance and Seedling Health Care

• Dosage: 0.5 kg per mu per meter of water depth

• Usage: Sprinkle 2–4 hours before water exchange, netting, transportation, or sudden weather changes

• Application: Seedling release and stress-prone periods, reducing mortality and improving vitality

(5) Feed Mixing for Internal Administration and Efficiency Enhancement

• Dosage: 5–10 grams per kilogram of feed

• Usage: Mix evenly for feeding, 2–3 times a week

• Application: Whole-process health care, promoting digestion, enhancing immunity, reducing feed coefficient, suitable for high-density aquaculture

III. Key Notes: Scientific Usage to Avoid Misunderstandings

1. Choose high-quality potassium fulvate: It has high activity, low impurities, and good water solubility, with effects far superior to biochemical products. Avoid inferior products that may affect water quality.

2. Fully dissolve before application: Do not spread dry directly; ensure uniform distribution across the entire pond to improve utilization rate and avoid local high concentrations.

3. Reasonable dosage control, no abuse: Excessive use may lead to excessive algal reproduction and algal bloom collapse; appropriately reduce the dosage in the middle and late stages to keep the water body clean.

4. Synergistic effect without conflict: It can be used in combination with probiotics, water fertilization paste, and trace elements; avoid simultaneous use with strong oxidants, strong acids, and strong bases, with an interval of more than 24 hours.

5. Combining with aeration for better effect: Turn on aerators after application to promote microbial activation and material decomposition, and improve the efficiency of water regulation and sediment improvement.

IV. Summary of Application Value: Core Efficiency Enhancer for Green Aquaculture

Potassium fulvate achieves triple regulation of water body, sediment, and organism in aquaculture. It not only purifies the environment, reduces diseases, and lowers drug costs but also improves growth rate, feed utilization rate, and survival rate. The comprehensive yield increase can reach 10%–15%, significantly enhancing economic benefits. At the same time, it reduces the use of chemical drugs, lowers aquaculture pollution, and conforms to the industry trends of ecological aquaculture and food safety.

In the future, with the popularization of green aquaculture technology, potassium fulvate will, by virtue of its safety, high efficiency, and multi-functionality advantages, become an essential input for improving quality and efficiency, stabilizing production and increasing income in aquaculture, helping farmers achieve a win-win situation between ecology and benefits.
