中国体育彩票11选5湖北开奖结果 www.xlzjp.com Biological and Nutritional Effects of
Artemia also known as abundance of shrimp, Artemia, salt water shrimp and other names. Belonging to the arthropod door, sub-shell sub-door, crustacean, gill foot subclass, no a head, salt water harvest insects.
Artemia is rich in protein, amino acids and fats, and is the best bait for shrimp. It contains 60% protein, 20% fat and polyunsaturated fatty acids. It is used in fish and shrimp nursery. Shrimp and fry have enhanced resistance, Increase the vitality and improve the survival rate of seedling survival rate, but also the seedling cultivation stage of the main nutrient source, so in the aquatic animal breeding process has been widely used.
The growth habits of the harvest
The Artemia that are commercially available are generally dormant eggs, and the dormant eggs can be preserved at low temperatures for long periods of time. When needed, they can be incubated at any time. The diameter of the eggs is 0.2-0.5 mm. The most suitable water temperature is at zero On the 20 ~ 30 degrees or so, the most suitable water salinity in the 10-15.
At present, the annual breeding of the annual breeding of eggs mainly from the Bohai Sea, the mainland's saline-alkali pool and the United States of the Great Salt Lake.
Incubation process is the most important process in the process, it is to go through a certain period of diapause, frozen, back to the water to hatch.
If the salinity can not hit 10% -15%, hatching rate will be reduced, the incubator can not often open, if often open, the temperature is reduced, hit less than 20-30 degrees, its hatching rate will be reduced.
Remove the eggs from the frozen cold storage at room temperature when the maximum temperature can not exceed 7 degrees.
Hatching rate to achieve a certain effect, you can enter the halide pool, the salty tank salinity up to 24 degrees or more, to impurities in the brine soak for 24 hours or more, you can out of the pool.
And then filled with fresh water, dry 24 hours, you can process, and put into the drying box needs 30 degrees of heating and drying. Drying tank level contains more water, so you can maintain a stable hatching rate, and then into the processing of two. Or with halogen sterilization, which is our usual processing of eggs.
Drying process, the first level oven can reach more than 5 hours, direct access to the technician saw a good worm, you can measure the 30 hours of moisture, you can out of the box, and then into the two boxes.
Secondary box is to reduce the contained water, and then filter, you can see our finished.
In the static hatch cup, good eggs are very active.
After the egg processing, in accordance with the needs of users, will be finished bagging, packaging. When the farmers need to use the worm, you can directly hatch the finished product.
The details of the attention during the incubation process
Incubation box this part: magnifying the number of eggs when the need to remove impurities; into the incubator back door can not often open; incubation temperature and salinity should pay attention to control.
Freezer inside that out when the buffer, you need to pay attention to the temperature can not be too high.
