The water depth of shrimp culture is appropriate, with appropriate water hardness and ph value.

The suitable water depth for shrimp culture is 0.9-1.5m, the pH value for shrimp growth is 7.78.8.The suitable hardness of shrimp culture water is above 250mg/L, and the suitable total alkalinity is more than 80. corresponding measures should be taken when it is lower than 80 or higher than 400m.

1. How deep is the water for raising shrimp?

In general, the suitable water depth for shrimp culture is 0.9-1.5m, and the range of ph value for shrimp growth is 7.78.8.The suitable hardness of shrimp culture water is above 250mg/L, and the suitable total alkalinity is above 80. measures should be taken if it is lower than 80 or higher than 400.

Second, the growing environment of shrimp

1. Shrimp swimming is different from fish in that the fish can swim forward by swinging its caudal fin, while shrimp does not have a caudal fin like a fish, but only one tail and many calves. Shrimp is a good swimmer and can swim long distances with its legs. when swimming, the swimming feet paddle back as frequently as wooden oars, and the body slowly drives forward.

2. When frightened, its abdomen bends and extends quickly, its tail paddles down and forward, and it can jump back continuously, and the speed is very fast. Some shrimps are not good at swimming, and the lobster climbs on the sand and gravel on the bottom of the sea most of the time.

III. Classification of shrimp

1, shrimp according to the source of production, mainly divided into sea shrimp and freshwater shrimp two kinds, sea shrimp is also called red shrimp, including lobster and prawn, etc., in which the taste of shrimp is better, for food in the upper taste, seafood, the North Atlantic common European shrimp, about 8cm long, gray or dark brown, with brown or light red spots.

2. Setae shrimp is distributed along the coast from North Carolina to Mexico and grows as 18cm. The larvae live in shallow bay and then enter the deep sea to feed on small animals and plants. The above two species have important economic value with brown ditch shrimp and pink ditch shrimp. Crangon franciscorum is a large shrimp of the Pacific Ocean, freshwater shrimp such as spoon shrimp, mainly in warm areas, some in brackish water, some as long as 20cm.

3. Ataephyra desmarestii is 1.6-2.7cm, mainly distributed in the freshwater waters of Europe, North Africa and the near East, living in groups of aquatic plants. The genus Syncaris in California is 2-5cm, and Palaemonias ganteri is half the length of the former, only found in Mammers Cave, Kentucky, which is famous for freshwater prawns in North America.

4. Xiphocaris is distributed in the freshwater of the West Indies, and the genus Macrobrachium or Palaemon is edible, mainly distributed in the tropics. Alpheus can grow to 3.5cm and stun its prey with large claws. The red sea prawns live in the same hole as the goby, and the fish send danger signals to the shrimp through physical exercise.

5. The tropical mackerel (Stenopus hispidus) grows as 3.5cm, and the coral fish swims upside down from its claws to remove dirt from the scales. The fairy shrimp is shaped like a shrimp, but it belongs to the order Anostraca, and the transparent one is the newly grown shrimp.
