The growth rate of prawns is not only related to shrimp density, species, environment, etc., but also directly related to accurate feeding. Because in the shrimp breeding management process, the appetite and growth of the shrimp can be observed through the real-time monitoring of the feeding platform, and the health of the shrimp can be observed by viewing the feeding platform, and the adaptation of the shrimp to the environment and the adequacy of feed feeding can be found in time Whether or not, through the observation of the material table can make management adjustments and treatment in a timely manner.
Material table requirements: 40-50cm in diameter and 10-15cm in height.
Do not place the material table around the aerator, do not place it in areas with rapid water flow, and do not place it too close to the side.
How to judge whether the input is enough from the material table? What else can you see at the table?
1.Look at the remaining material
There are individual feeds and more shrimps in the feeding table within the specified time, indicating that the feed is just right, and no feeding is required for meals. If there is no feed in the feeding table but there are many shrimps, it means that the feed is slightly insufficient, and you can properly feed; It means that the feed is not enough, and it must be added; if there is more feed on the feed table, it means that the feed is too much, and the feed can be appropriately reduced or not thrown.

2. Look at shrimp feces
The length of the feces is about 75px and the color is the same as the color of the feed, which means that the amount of feed is sufficient; if the length of the feces is too short and the color is dark brown, it means that the amount of feed is insufficient.
3. Look at the shrimp
The main observations are the body color of the shrimp, liver color, outline, whether it is enlarged and atrophic, intestinal fullness, and vitality.
4.Assist in judging the quality of water
Excellent water quality: It is relatively smooth when the material table is lifted, because the viscosity of the water body is small, and the material table has fewer attachments. Poor water quality: It will be more laborious to lift the lotus root, because there are dead algae and dead bacteria attached, and the water viscosity is too high.

5. Is the shrimp long or not?
Is the prawn eating long or light? Weigh the shrimp regularly to determine if the growth rate is normal.
Summary: check the material table, observe the material table first to see if there is remaining material, and then according to the shrimp situation (check the size, length, color and uniformity of shrimp manure, check the health and vitality of shrimp liver and intestine), combine the weather and water temperature Environmental factors such as water quality. Comprehensive analysis before deciding whether to increase or decrease the amount of feed, this is a reasonable breeding management method.
