Determination for Artemia Cysts Quality  2009-4-1

1.Hatch Rate (HR%)

This is ascertained by first finding out the Cyst Per Gram (CPG) count and then finding out the Nauplii Per Gram count and dividing the two as NPG / CPG.
This number is crucial because it is the industry standard by which brine shrimp eggs are sold. However, as we are dealing with a living organism, there are inherent differences with the physical properties of brine shrimp eggs.  Variations that may affect the HR % can be due to many factors including the source location of the eggs, the biological strain of the eggs, processing methods, and so on.

2.Nauplii Per Gram (NPG)

This is calculated by obtaining the total number of newly hatched nauplii within the hatching container and dividing this number by the number of grams of brine shrimp eggs that were put into the hatching container at first.
This number is important because this is the number of brine shrimp nauplii individuals that the customer is getting. It is also significant because this is the end product, i.e., this is what will be consumed by the fish or shrimp larvae. Many hatchery technicians base their feeding regimes on the NPG.

3. Separation

This is a subjective indicator determined by the person in charge of hatching out the brine shrimp eggs.  It is derived by first visually observing a sample of approximately 500-1000 ml in an imhoff cone or glass beaker from the hatching container immediately prior to harvesting the brine shrimp nauplii to note the separation of newly hatched brine shrimp nauplii from un-hatched eggs and shells. With excellent separation, one should observe mostly newly hatched brine shrimp nauplii, with little to none eggs or shells on the bottom of the cone or beaker.
This step is important because the introduction of un-hatched eggs and shells into the larval rearing tanks can cause water to be impure, leading to health related problems with the cultured organisms.

BHB Artemia Cysts Instruction  2009-4-13


We offer 100% Bohai Bay(BHB) Brine Shrimp eggs (Artemia cysts) processed by state-of-the-art fludidized dryers.

The common brine shrimp (artemia) is in the phylum Arthropoda, class Crustacea. It commonly is used as feeds for larval and post larval shrimp and fish.Artemia are zooplankton like Copepods and Daphnia, which are also used for live food in the aquarium.

The artemia life cycle begins by the hatching of dormant cysts, which are encased embryos that are metabolically inactive.

The cysts can remain dormant for many years as long as they are kept dry and oxygen free. When the cysts are placed back into salt water they are re-hydrated and resume their development. This process is also known as hatching. Artemia cysts are best stored in a tightly sealed container in a cool dry environment, if possible, vacuum packed.

 

How is Chlorella  2009-3-6

Chlorella was discovered in the late 19th century. Due to its high protein concentration and rapid growth rate, chlorella was investigated after World War II as a possible commercial food source. In the 1960s, some investigators claimed that the algae decreased the side effects of chemotherapy and slowed the growth of some cancer cells. Most of the research has been conducted in Japan, where chlorella is a top-selling dietary supplement.

Chlorella is a single-celled freshwater alga. These algae contain large amount of chlorophyll, the chemical that gives plants their green color. Chlorophyll is an essential compound for photosynthesis, the process by which plants convert light into chemical energy. Chlorophyll is also available in green leafy vegetables.

How is Spirulina  2009-3-6

Blue-green algae are a group of life forms which appeared on the Earth approximately 3.0 billion years ago, and spirulina belongs to this group. Spirulina has since survived without much evolution until today, and therefore it still displays primitive features, but it is a thriving life form with an extremely high vitality.

Spirulina is considered to have been born before the plant and animal kingdoms split, and therefore it is a very rare organism which has characteristics of both plants and animals.

In addition to the nutritional elements typically contained in green-yellow vegetables, spirulina also contains high-quality proteins, and therefore it is considered to be a holistic dietary supplement; it has also an excellent digestive absorption rate.
