Simply , the color of the artemia is one of the most intuitive and important indicators for judging its quality and nutritional value. We can regard the color of the artemia as a quality indicator, where different colors represent different states and nutritional compositions.
1. Vibrant Orange Red – High Quality
This color mainly comes from natural food – algae in water (such as salt algae), which are rich in natural pigments and nutrients such as astaxanthin and carotenoids
This is the most highly respected and highest quality artemia, especially suitable for feeding high-value ornamental fish, shrimp fry, and seed fish.
2. Light yellow/gray white – poor quality
This color usually indicates that the artemia hatched and starved for a long time in poor water bodies, or had a single source of food and insufficient nutrition.
Belonging to low-end products, not recommended for feeding fish and shrimp with nutritional requirements.
Dark brown/black – deteriorated
This is usually not the color of the artemia itself, but rather caused by improper storage, moisture, mold, or oxidative decay.
Absolutely cannot be used, feeding spoiled artemia can pollute water quality and may lead to fish and shrimp poisoning, illness, or even death.
In addition to color, when selecting artemia cysts, it is also important to pay attention to the following:
Morphological integrity: High quality artemia cysts should have intact individuals and minimal debris
Odor: There should be a fresh seaweed smell, rather than a pungent putrid or fuel consuming odor.
Purity: The less impurities, the better
Processing method: Freezing artemia can better preserve nutrients; The decapsulated artemia cysts results in a slight loss of single nutrition; Pay attention to whether nutrient fortifiers have been added to dry artemia cysts.
The color and quality of artemia cysts have a decisive relationship. When choosing, be sure to choose products with bright colors, such as orange red. This small observation can ensure that you provide the highest quality and safest food for your beloved fish and shrimp, allowing them to grow up healthy and colorful
