The spot prawn is saltwater farmed.
The spot prawn is a brackish water species and belongs to the sea shrimp. Spot prawns have a wide distribution area, in the coast of China, southern Japan, South Korea, the Philippines, Indonesia, Australia, Thailand, India to the eastern coast of Africa are distributed. China's coastal areas in February-April, August-November each year for the spot prawn spawning period. Spotted shrimp fast-growing, adaptable, omnivorous, low bait protein content requirements, only about 35%, can tolerate a wide range of salinity and temperature.
Spotted shrimp need seawater aquaculture, because the spotted shrimp belongs to the brackish water category, freshwater aquaculture is not conducive to its growth, so the need for seawater aquaculture, in the aquaculture process, you need to choose the abandoned pond as a breeding site, and then you can grow healthy shrimp seedlings into which, the later management, you need to regularly change the water to add water to ensure that the water quality of the water is clean.
Spotted shrimp morphological characteristics of the introduction:
The body was black-brown, earthy yellow interspersed with horizontal spots pattern. The upper rostrum of the frontal horn is 7 to 8 teeth and the lower rostrum is 2 to 3 teeth. The lateral frontal horn groove is quite deep and extends behind the supraocular spines, but the lateral frontal horn ridges are low and blunt, and the central groove of the posterior frontal horn ridges is distinct. There are obvious hepatic ridges and no frontal gastric ridges. Spot prawns are fast-growing, adaptable, omnivorous, requiring low protein content of bait (only about 35%), and can tolerate a wide range of salinity and temperature. Salinity range of 0.2 ~ 70 ‰, the optimal salinity of 10 ~ 20 ‰.
The optimum temperature is 25 to 32 degrees Celsius, higher than 38 degrees Celsius or lower than 14 degrees Celsius will cause death. Low oxygen tolerance is also strong, can withstand a long time of dry dew, so easy to work and transportation. The shrimp is the largest individual shrimp of a kind, found the largest individual up to 33 centimeters long, weighing 500 to 600 grams.
