The adaptable water temperature is 10~37℃, and the optimal growth temperature is 17~32℃. The suitable salinity is 3.5%, and it has a wide adaptability to salinity. It can grow in fresh water and survive in seawater with a salinity of more than 35‰. Tolerance to low dissolved oxygen is relatively strong. It can live normally in water with a pH value of 7.0 to 9.0.

Start adding well water to the shrimp pond 5 days after the seedlings are released. Add water once every 2 days, adding 5 cm of water each time until the shrimp pond reaches the water storage depth. The pool water should be filled up during hot weather in summer. Add water to the upper limit of shrimp pond storage 1 to 2 days before a heavy rain, so that the falling rainwater will naturally overflow through the upper edge of the gate plate to prevent rainwater from salinizing the shrimp pond and causing a significant drop in pH value, which will affect the growth of shrimps or cause shrimp death. .

Living environment:

Respiration and circulation The gills of prawns are located in the gill chambers formed on both sides of the carapace. The front, rear and ventral surfaces of the gill chambers are connected to the outside world. Connected. The gills are mostly feather-shaped, with 25 pairs in total. They are located on the side walls of the chest or the base of the thoracic limbs. The epidermis is extremely thin, and gas exchange occurs when blood flows through the gills. There is a scaphoid in the gill chamber that continuously swings, allowing fresh water to enter from the back and ventral surface and flow out forward.

The circulation system is open-tube. The heart is a flat polygonal muscular sac located in the pericardial sinus on the dorsal side of the cephalothorax. It has 4 pairs of cardiac pores, two pairs on the back, one pair on both sides of the rear end, and the other pair on the ventral surface of the heart near the rear end. There are valves that control the flow of blood.
