Penaeus monodon (bamboo shrimp)

Its adaptation range to salinity is 5 ~ 25, and the closer to 10 the faster it grows. The maximum body length of Penaeus monodon caught in natural sea areas can reach 33 centimeters, and the weight can reach 500 grams to 600 grams. Each kilogram of shrimp can reach 40 to 60. The average yield per mu is 100kg to 200kg. Two shrimps can be raised in 1 year. Generally, the tidal range should be between 2 meters and 3 meters, the duration of high tide should be no less than 3 hours, and the salinity of sea water should be 10～20, 0.7 square kilometers ~ 1.0 square kilometers. The depth of the pond is 2.0 meters, and the water depth is about 1.5 meters. The bottom of the pond should be flat, and the bottom of the drainage gate should be lower than the bottom of the pond1/3~1/2 of the shrimp pond area. When building a new shrimp pond, the gate should be opened to allow seawater to flow in and out for flushing, so that the ph value at the bottom of the pond is stable above 7.5 before shrimp seedlings can be released.
After spreading tea bran 2 days to 3 days, add water 80cm to 100cm, apply urea 2kg per acre, and phosphate fertilizer ph value is between 8.0～8.5, the water color is yellow-green or green, and the seedlings can be released after 6 days to 10 days. The shrimp larvae are required to be uniform in size, strong, vigorous, good in reverse swimming ability, with a smooth body surface without attachments, and a body length of more than 1.2 centimeters. The front end of the first antennae bifurcates into two small tentacles in a v shape and often come together, with sparse and long body segments. Generally, the water depth of shrimp ponds is about 1.2 meters, and the number of seedlings per mu is 0.8 to 1.0 million; When releasing seedlings, first put the seedling bag into the pond and soak it for 20 minutes, so that the water temperature in the bag is close to the water temperature in the pond (the temperature difference does not exceed 3℃). Release the seedlings downwind in a place with deeper water upwind, and the salinity difference between the shrimp seedling pond water and the shrimp pond water does not exceed 4 times a day, at 5:30, 9:30, 18:00, A shrimp pond of 8.5 acres can be equipped with 4 to 6 nets for observation. Shrimp farms should purchase water quality monitoring instruments such as colorimeter, hydrometer, thermometer, and oxygen meter to measure the pool water temperature, specific gravity, ph value, transparency, dissolved oxygen and other physical and chemical indicators, and keep records in order to monitor and adjust the water quality and maintain the pool water ph value
Feed medicinal bait once every half month, according to vitamins c3‰～5‰, allicin 2‰, cod liver oil 3‰～80 days to 100 days, with an average of 40 to 60 tails per kilogram of shrimp, and 90% should be harvested and sold when they reach commercial specifications.
