Decapsulated Brine Shrimp Eggs (Non-Hatching)

Decapsulated Brine Shrimp Eggs (Non-Hatching)

Product Overview

Decapsulated Brine Shrimp Eggs (Non-Hatching) are produced from high-quality brine shrimp cysts harvested from salt lakes. Through strictly controlled decapsulation, neutralization, rinsing and drying processes, the hard outer shell is removed and only the embryo rich in protein and lipids is retained.

The product is supplied as a dry fine granule or powder, which can be fed directly or after rehydration. No hatching equipment or dedicated staff are required.

Compared with traditional hatch-required brine shrimp eggs, this product offers:

  • No hatching needed – ready to use, simplified operation

  • Shells removed – high digestibility, less residue

  • Powder / fine granule form – compatible with automatic feeders and feed production lines

  • Batch traceability – suitable for farms, feed mills and aquatic retailers with long-term, stable usage

This product is positioned as a standardized ingredient for professional use and is suitable for ornamental fish farms, aquaculture farms, aquatic retail chains, aquatic feed manufacturers and research institutes.

Technology & Advantages

1. Decapsulation principle

  • Dormant brine shrimp cysts are selected as raw material.

  • The outer shell is dissolved and removed using an oxidizing solution under precisely controlled concentration and exposure time.

  • The product is neutralized and rinsed several times to remove residual chemicals.

  • Low-temperature drying and sieving yield a uniform decapsulated product.

Decapsulated brine shrimp eggs lose their ability to hatch, but retain a nutritional profile close to that of freshly hatched nauplii and can be directly consumed by fish and shrimp.

2. Comparison with traditional hatching of brine shrimp eggs

Operation

  • Traditional eggs: require brine preparation, aeration, temperature and light control, 24–36 h hatching, separation of nauplii and shells.

  • Ready-to-use decapsulated eggs: ready immediately after opening, only weighing and feeding are required.

Water quality and leftovers

  • Traditional hatching: large amounts of empty shells float or settle, easily causing filter blockage and bottom deposition.

  • Decapsulated eggs: shells are removed, animals digest the product easily, and solid waste is significantly reduced, helping to maintain cleaner water.

Nutrient utilization and stability

  • Traditional hatching: nauplii consume part of their energy during hatching and swimming.

  • Decapsulated eggs: fish and shrimp ingest the embryo directly, energy is more concentrated and the effective utilization of each unit of feed is improved.

3. Product advantages

  • Low nutritional variation – raw material grading and process control reduce batch-to-batch variation in key indicators such as protein and fat, making long-term purchasing and formulation easier.

  • Controlled particle size – particle sizes are adjusted for fry and small fish feeding, improving feeding efficiency and suspension time.

  • Automation-friendly – good flowability and low caking tendency, suitable for automatic feeders and dosing systems.

  • Complete documentation – batch test reports (COA) and related compliance documents can be provided to support feed manufacturers and farms in registration and audit processes.

Nutritional Composition & Physical Properties

The following values are typical ranges. Please refer to the COA of each batch for exact data.

1. Main nutritional indicators (on dry matter basis)

  • Crude protein: approx. ≥ 58–60%

  • Crude fat: approx. ≥ 10–15%

  • Crude ash: approx. ≤ 5–8%

  • Moisture: approx. ≤ 8–10%

2. Physical properties

  • Form: fine granules / powder

  • Color: light brown to orange-brown

  • Particle size: suitable for fry and small ornamental fish, with good suspension in water

  • Dispersibility: quickly wets after entering the water and remains suspended for a period of time, allowing active feeding and reducing rapid sinking losses

Directions for Use

1. Direct dry feeding

Recommended for: ornamental fish shops, home aquaria, certain grow-out tanks.

Steps

  1. Estimate the amount per feeding based on fish number and biomass.

  2. Sprinkle the product evenly over the water surface.

  3. Adjust the feeding rate so that most of the feed is consumed within 5–10 minutes. If there is obvious leftover on the bottom, reduce the next feeding.

2. Feeding after rehydration

Recommended for fry, larvae, smaller animals or cautious feeders.

Steps

  1. Add the required amount of product into clean culture water.

  2. Let it soak for 5–10 minutes so that the particles are fully hydrated and evenly dispersed.

  3. Slowly pour the suspension along the water surface or tank edge so that the feed forms a “cloud” in the water column.

3. Use as a feed ingredient

Recommended for feed mills, premix producers and farms making in-house feeds.

  • Suggested inclusion rate: about 3–10% of the total diet, adjustable according to species, growth stage and cost target.

  • Can be combined with fish meal, shrimp meal and other protein sources to enhance palatability and daily feed intake.

  • In extrusion or pelleting, avoid excessive temperature and residence time to protect heat-sensitive nutrients.

4. Example species and stages

  • Tropical ornamental fish: guppies, tetras, angelfish, cichlids, etc.

  • Goldfish and koi juveniles and medium-size fish

  • Marine ornamental fish juveniles and small marine species

  • Larvae of shrimp, crab and other crustaceans

  • Adult or ornamental fish requiring high-protein attractant feeds

Economic & Management Advantages

1. Reduced equipment and maintenance costs

No need for hatching cones, air pumps, lighting or dedicated hatching rooms and staff, which lowers both initial investment and ongoing maintenance expenses.

2. Reduced labor and time costs

Eliminates steps such as brine preparation, nauplii collection and shell washing, reducing manual operations and potential errors, allowing staff to focus on water quality management and routine inspection.

3. Stable and controllable feeding program

Ready-to-use products are far less affected by external factors such as temperature, power outages or hatching water quality, minimizing feed interruption risks and supporting stable production planning.

4. Easier standardization

Combined with weighing tools and feeding protocols, clear records of feeding and consumption can be maintained, which is helpful for cost accounting and production management.
