A basic introduction to freshwater shrimp
Freshwater shrimp mainly in warm areas, some in semi-saline water, distributed in Europe, North Africa and the Near East, freshwater waters, living in groups in aquatic plants. Freshwater shrimp are green shrimp, river shrimp, grass shrimp, etc.; there are also semi-saline water shrimp such as white shrimp.
Two, freshwater shrimp how to raise?
Select robust, disease-free and injury-free freshwater shrimp farming, prepare a pond suitable for freshwater shrimp growth and set up anti-escape measures, shrimp fry into the pond, you need to put the bait on time, and do a good job in the management of temperature, PH and other factors.
Which:
Shrimp fry selection also need to pay attention to, the length of shrimp fry should be more than 0.8 centimeters, shrimp species specifications in more than 3 centimeters is best. The same batch of breeding shrimp, the size should be basically consistent. Shrimp vitality must be tenacious, generally nowadays shrimp fry are artificially bred, if you want to put the wild, it is best to separate from the artificially bred, so as not to fight with each other and reduce production.
The depth of the pond for breeding should be between 1-1.5 meters, and the area should be more than 4 acres, but not too big, not more than 10 acres, the edge of the pond should be sloped, and the bottom of the soil should be soft and flat. The slope of the pool edge should be hard and the water source should be of good quality. It is best to have a water level control system and a scientific drainage and irrigation system.
Anti-escape measures are usually made of plastic film or plastic sheets. Before we put water, we need to thoroughly disinfect the pond once, you can use quicklime, bleaching powder, bleaching powder essence and so on, after disinfection, the pond needs to be air-dried for about a month or so, you can put water into the pond under the shrimp seedlings.
Three, the nutritional value of freshwater shrimp
1, containing relatively rich in protein and calcium and other nutrients, so it can not be eaten with fruits containing tannins, such as grapes, pomegranate, hawthorn, persimmons and so on, otherwise it will stimulate the stomach and intestines, causing discomfort, vomiting, dizziness, nausea and abdominal pain, diarrhea and other symptoms. Seafood and these fruits eaten together, should be at least 2 hours apart.
2, shrimp is rich in calcium, but also contains a kind of animal fiber known as chitin, which is a kind of polysaccharide, after chemical treatment and dissolve it in water can be made into health food chitosan.
3, shrimp is rich in magnesium, magnesium has an important role in regulating cardiac activity, can protect the cardiovascular system, it can reduce blood cholesterol content, can prevent atherosclerosis at the same time can also expand the coronary arteries, is conducive to the prevention of hypertension and myocardial infarction.
