1 Glutathione: Aquatic Animals' Internal Defense and External Enhancement

Glutathione is a naturally occurring core antioxidant in living organisms, with its levels directly determining the health status of aquatic animals. Understanding its sources and metabolic pathways is key to effectively utilizing this multifunctional additive.

 

1.1 Dual Assurance of Endogenous Synthesis and Exogenous Supplementation

In aquatic animals, glutathione is primarily synthesized in the liver, a process highly dependent on key enzyme activity and sufficient substrate supply. However, in intensive aquaculture, factors like oxidative stress, disease outbreaks, or toxin exposure often reduce endogenous synthesis capacity, creating an “antioxidant defense gap.”

 

At this point, exogenous supplementation of glutathione through feed becomes crucial. Green Spring Technology's high-purity glutathione raw material is efficiently utilized by aquatic animals, directly bridging this gap and helping maintain robust defense systems.

 

1.2 Efficient Absorption and Systemic Action

Research indicates that glutathione is effectively absorbed in the intestinal tract of aquatic animals and transported via blood to vital organs like the hepatopancreas and kidneys for metabolism. This process forms the foundation for its core functions: scavenging free radicals, enhancing immunity, and detoxification.

 

When farmed fish and shrimp face environmental stress, exogenously supplemented glutathione rapidly participates in metabolism, effectively mitigating oxidative damage within the body and protecting hepatopancreatic health. This maintains normal growth and immune function, providing a solid material foundation for healthy aquaculture.

3.1 Research Demonstrates Glutathione Significantly Enhances Aquatic Animal Growth Performance

Studies across multiple key aquatic species show that adding glutathione to feed directly translates into substantial production performance gains. Its growth-promoting mechanisms are scientifically sound and multifaceted.

 

3.1.1 Activating Intrinsic Growth Potential

Glutathione does not merely stimulate growth; it activates the aquatic animals' own endocrine systems through scientific pathways. It significantly upregulates the expression of key genes such as insulin-like growth factor (IGF-I) and promotes the normal secretion of growth hormones, laying the physiological foundation for rapid growth.

 

● Evidence-Based Case: Research confirms that adding appropriate levels of glutathione to grass carp feed effectively increases IGF-I expression in their livers, ultimately resulting in significantly improved weight gain rates.

 

3.1.2 Optimizing Feed Nutrient Conversion

Enhanced growth performance is not just about “eating faster,” but also about “growing better.” Glutathione optimizes nutrient digestion and absorption by enhancing intestinal health.

● Empirical Case:

● Adding glutathione to crayfish feed effectively reduces the feed conversion ratio, meaning more aquatic products can be produced with the same feed input, directly lowering farming costs.

● Studies on tilapia show that glutathione supplementation significantly improves protein efficiency, enhances fish utilization of core nutrients, and achieves efficient growth.

 

3.1.3 Broad Applicability Across Major Aquaculture Species

Green Spring Technology's glutathione raw material has demonstrated growth-promoting effects across multiple high-value species, including but not limited to Litopenaeus vannamei, grass carp, rainbow trout, and tilapia.

3.2 Building an Internal Antioxidant Defense: Glutathione Addresses Stress Challenges in Intensive Aquaculture

Under intensive aquaculture systems, environmental stressors such as water quality fluctuations, high stocking densities, and pathogen threats lead to massive accumulation of free radicals in aquatic animals. This triggers oxidative stress, causing tissue damage, impaired immunity, and stunted growth. Glutathione, as the body's endogenous core antioxidant, serves as a critical defense against such damage.

 

3.2.1 Directly Scavenging Free Radicals to Maintain Homeostasis

Glutathione is the most abundant non-protein thiol compound within cells. Its unique thiol group (-SH) can directly donate electrons, efficiently neutralizing harmful free radicals and converting them into harmless substances. Simultaneously, it undergoes oxidation (GSSG) and is regenerated into its active form (GSH) by glutathione reductase, forming an efficient antioxidant recycling system that continuously maintains intracellular redox balance.

 

3.2.2 Enhancing Overall Antioxidant Enzyme Activity and Defensive Capabilities

Exogenous glutathione supplementation significantly increases glutathione reserves in aquatic animal tissues such as liver and blood. This not only directly enhances free radical scavenging capacity but also synergistically boosts the activity of core antioxidant enzymes like superoxide dismutase (SOD) and catalase (CAT), thereby comprehensively strengthening the organism's antioxidant defense system.

 

3.2.3 Empirical Evidence and Significant Effects

Studies on multiple high-value aquatic species—including turbot, Chinese mitten crab, white shrimp, and striped bass—confirm that adding appropriate doses of glutathione to feed effectively:

★ Reduces oxidative stress markers (e.g., malondialdehyde, MDA).

★ Enhances total antioxidant capacity (T-AOC) and related enzyme activity.

★ Alleviate tissue damage caused by environmental stressors.

 

3.2.4Scientific Supplementation is Critical

It is crucial to emphasize that the efficacy of glutathione supplementation depends on scientifically determined dosages. Green Spring Technology not only provides high-quality raw materials but also leverages the aforementioned research findings to offer clients scientifically grounded supplementation protocols.

Various stressors in aquaculture environments are fundamental causes of reduced immunity and frequent diseases in aquatic animals. Through its core antioxidant function and immune regulation mechanisms, glutathione comprehensively enhances both specific and non-specific immunity in aquatic animals, establishing a robust barrier for stable aquaculture production.

 

Core Immune Mechanisms

3.3.1 Eliminating the Root Cause of Immunosuppression

Immune function is closely linked to oxidative stress levels. As the body's primary endogenous antioxidant, glutathione directly scavenges free radicals generated by environmental stressors. This alleviates oxidative stress's suppression of the immune system at its source, creating conditions for immune function recovery.

 

3.3.2 Precise Regulation of Immune Activity

Glutathione significantly enhances the activity and expression of multiple key immune factors:

▲ Boosts Immune Enzyme Activity: In species like yellow catfish, it markedly increases lysozyme (LZM), alkaline phosphatase (AKP), and other enzyme activities while elevating immunoglobulin M (IgM) levels, thereby strengthening humoral immunity.

▲ Modulates immune signaling pathways: In Chinese mitten crab studies, it regulates the expression of key signaling pathway genes like Toll-like receptors (TLR), activating innate immune defenses.

▲ Alleviating Excessive Inflammation: Studies on carp confirm its ability to effectively mitigate tissue inflammation induced by ammonia nitrogen stress by regulating factors like interleukin (IL-1β, IL-6), preventing damage caused by immune system overreaction.

 

3.3.3 Activation of Key Immune Cells

Glutathione directly enhances immune cell activity. Trials on Nile tilapia demonstrate it significantly boosts respiratory burst activity in head kidney macrophages. Studies on grass carp also reveal that it increases blood leukocyte counts, thereby comprehensively strengthening non-specific immunity and disease resistance.

3.4 Dual Detoxification Mechanism: Safeguarding Hepatobiliary and Intestinal Health in Aquatic Animals

Harmful substances in aquaculture water—such as ammonia nitrogen, algal toxins, pesticide residues, and mycotoxins in feed—constantly challenge aquatic animals' detoxification systems, with the liver serving as the primary metabolic and detoxification organ. As a core component of the body's detoxification system, glutathione effectively mitigates the harm of exogenous toxins to aquatic animals through the following dual mechanisms.

 

Core Detoxification Mechanism

3.4.1 Antioxidant Detoxification: Neutralizing Indirect Toxin Damage

Upon entering the body, most toxins induce massive free radical production, causing oxidative damage—a key manifestation of their toxicity. As a core antioxidant, glutathione:

★ Directly scavenges free radicals, blocking the oxidative damage pathway of toxins.

★ Inhibit lipid peroxidation, preserving the integrity of cell membrane structures.

● Empirical Evidence: Studies demonstrate that glutathione effectively mitigates microcystin damage in grass carp and improves liver function impaired by aflatoxin poisoning in tilapia.

 

3.4.2 Binding Detoxification: Direct Neutralization and Toxin Elimination

This represents glutathione's most distinctive detoxification pathway. Its molecular sulfhydryl group (-SH) directly forms covalent bonds with various electrophilic toxins, creating non-toxic or low-toxicity water-soluble complexes that are excreted via bile or urine. This mechanism proves particularly effective against:

★ Biotoxins: e.g., binding to microcystins to accelerate their clearance from yellow catfish.

★ Organophosphorus pesticides: Forms intermediate compounds with phosmet, reducing drug residues in the livers of silver crucian carp.

★ Heavy metals: Chelates metal ions like lead, promoting their excretion from tilapia.

 

What benefits does it offer?

For feed manufacturers, incorporating Green Spring Technology's glutathione raw material into formulations is equivalent to embedding a highly efficient “detoxification engine” within farmed animals. This helps your clients:

● Mitigate growth suppression caused by deteriorating water quality (ammonia nitrogen, algal toxins) and feed contamination (mycotoxins).
