The highlights of prawn culture

Prawn Penaeus monodon, also known as Taiwan grass shrimp and flower prawn, is the largest single species of shrimp today, weighing around 150g to 250g, and is one of the most prized shrimps favored by consumers.
First, the pond selection pond area is suitable for 3 mu ~ 5 mu, the bottom of the pool is flat, the effective depth of water should be maintained at 1.5 meters or more, abundant water, no pollution.
2. Disinfection in clear ponds For ponds that have reared fish or raised shrimp, it is necessary to thoroughly dredge and disinfect with 200 kg of quick lime per acre after exposure. If the pond contains wild miscellaneous fish, 20 to 25 g/m3 of tea seed cake can be used to kill fish.
Third, the demand for salinity Pterodactyl prawn, there are dark brown horizontal stripes pattern, is a widely salted shrimp species. The requirement for salinity must be maintained at more than 5 , for shrimp to grow normally and not less than 5 盐 for salinity.
4. Before the shrimp ponds in shrimp ponds are put on seedlings, they must be treated with fertilizer and water to ensure that the shrimps have sufficient natural food for feeding after entering the pond. With organic fertilizer (such as fermented chicken manure, etc.), using the method of hanging bags put in the pool, the amount per acre of 100 kg to 150 kg, the required pool water transparency in the 30 cm to 40 cm.
V. Putting seedlings Before the shrimp seedlings are released, it is necessary to use a small amount of shrimp seedlings to test the water. After the water is determined to be free of problems, the seedlings are released. The amount to be put is generally 20,000 to 30,000 per acre. The healthy and lively shrimps should be selected for stocking. The temperature difference when the shrimp seedlings are placed should not exceed 4°C, the salinity difference should be about 5, and the salinity difference should not be too large.
Sixth, after scientific feeding of shrimp, it is necessary to choose good quality brand feed for feeding. Adhere to the patrol pond once a day in the morning and in the evening, and increase the oxygen in the hot season to increase the oxygen capacity in the water. For a well-watered pond, it is necessary to increase the water exchange capacity of the shrimp pond and ensure fresh water quality.
VII. Prevention of Shrimp Disease The occurrence of shrimp disease is fundamentally due to the deterioration of farming conditions and the environment, resulting in the decline of shrimp resistance and the occurrence of shrimp disease. During the whole breeding period, we must regularly disinfect and implement the principle of prevention. The use of some biological agents to improve water quality can play a good preventive role.
8. Arrest and arrest time, and be flexible in light of changes in climate and water temperature. The methods of harvesting can be harvested using various fishing methods such as ground cages, whiskers nets, and power grids.
