Measure the PH value from 6: 30 to 7: 00 every morning. If the PH value is lower than 7.0 in the morning, lime should be applied to improve it, and fertilizer should be considered. Ammonia nitrogen and nitrite are measured every 3 days. Observe the shrimp and observe the eating table to see whether the shrimp in the eating table is healthy (body color, tentacles, swimming feet, gills, liver and pancreas, stomach, intestines, feces, etc.) and whether there are shrimp shells. If there are shrimp shells, shrimp may shed more shells at night, so it is necessary to strengthen calcium supplementation. Mixing and feeding the first meal in the morning is generally not too early, because the dissolved oxygen in the water body is relatively low too early, which will affect the feeding. It is more appropriate to feed from 7: 30 to 8: 00. When feeding, the aerator can be stopped 1-2 hours. Patrol the pond to observe.

Penaeus orientalis (also known as China Penaeus, China Fenneropenaeus and Penaeus monodon) is a kind of shrimp belonging to Arthropoda, mollusca, Decapoda, Penaeidae and Penaeus. Penaeus is a large individual, commonly known as prawn. After a large number of commercial aquaculture, the output of shrimp is increasing rapidly. The cooking methods of the whole prawn include braising, frying and sweet roasting.

Penaeus belongs to Arthropoda, Branchial Subdivision, Crustacea, soft armor Subdivision, Decapoda, Swimming Subdivision, Penaeidae and Penaeus. Penaeus China is one of the main species of Penaeus, commonly known as "Penaeus". The body of prawn is long and slightly flat, hermaphroditic, and the adult female shrimp is larger than the male shrimp, and the body color is also different. The female prawns in China are gray-blue, while the male prawns are yellow. Shrimp is covered with a chitin exoskeleton, which is secreted by epidermal cells below it.
