The harvesting season of Artemia eggs is generally in the fall, but there are also a few Artemia eggs that can be harvested in the spring. In addition to the parasitizing dormant eggs produced by Artemia Monodon from California, most of the Artemia eggs produced in other regions are floating eggs. Eggs are often washed up by storms and piled together on the shore. They are pale reddish-brown. Can be scraped directly from the shore, or use a special trinkets to pick eggs floating in the water or suspended in the downwind. If it is used to collect Artemia eggs that have been blown to shore, it is common to use square nets (40 mesh nets, 90 mesh nets). If they are used to collect Artemia eggs in water, circular nets are often used. (40 above, 90 below). In addition, it is also possible to dig pits or construct floating gratings in pools to concentrate eggs in local water bodies for harvesting.
Freshly collected eggs should not be piled up, but generally go through the following processing steps: Cleaning: Cleaning is generally done in a conical bucket, first with fresh water and then with seawater. The main purpose of flushing is to remove debris, egg shells and dirt on the surface. Dehydration: The method of dehydration of wet eggs is generally followed by centrifugation followed by dryness; and dry eggs, should be vacuum dried after low temperature. (Make the egg's moisture content in the range of 2%-8%) Dry: In the air and in the drying, to prevent the temperature is too high (not more than 40 degrees) and exposure to sunlight. Screening: Layering with different pore size screens.
Packaging: vacuum or nitrogen sealed packaging.
Storage: Wet eggs are kept in cold storage. At the same time, they should be kept at -18 degrees for one week and then kept at room temperature for one week. Dry eggs can be stored at low temperatures. After the eggs of the Artemia eggs that have been processed in the above steps, the egg-keeping rate can still be maintained at 70% in the right after several years of storage.
