Description

How to use

It should be positioned in the pond close to the bottom, but not touching it, in a clean area that is slightly elevated from the pond bottom. The number of feeding trays that should be used will vary depending on the size of the pond and the density of shrimp being farmed.

During the first 10-15 days after stocking post larvae, the feeding program primarily focuses on fry quantity, a process known as blind feeding. The daily feed volume given to post larvae (PL) is intentionally programmed to be excessive during this period. After blind feeding, only the pond’s supervisor should use feeding trays.

Function

Monitors the feeding pattern of the shrimp

Pond’s supervisor can gain valuable information about the feeding habits of the shrimp and the conditions within the pond. Inspections can be conducted at intervals of 1 to 2 hours to check the amount of feed in the feeding trays and observe how quickly the shrimp consume the feed. Based on the observations, adjustments can be made to the feeding program, such as changing the amount of feed given at the next meal, increasing or decreasing the amount of feed for a specific meal or plan the overall next day’s feed for the shrimp. It’s important to note that the amount of feed given should be adjusted based on the actual situation, including the pond environment, weather, and other factors.

The following table outlines the recommended actions to be taken based on the amount of feed leftover in the feeding trays.
Inspections can be conducted at intervals of 1 to 2 hours

Feed leftover (%)	Action
0	Increase 5% feed amount for the next feeding time.
10	Keep the same amount/td>
11 – 25	Reduce 10% feed amount for next feeding time
26 – 50	Reduce 30% feed amount for next feeding time.
> 50	Stop feeding the next time

Monitor shrimp performance and health conditions

Pond’s supervisor can observe the appearance of the cultured shrimp, which can reflect their appetite, health, and growth rate. These aspects include shrimp vitality, physical appearance, and gut condition. Healthy shrimp will display strong vitality, good physical appearance, and a full gut, while unhealthy shrimp will display low vitality, pale white physical appearance, and the absence of feed in the gut.

Note: when weather changes, such as severe rainy or sunny days, feed only 70-80% of the amount of required feed for shrimp. Observing shrimp’s molting period to reduce the amount food intake, and increase after the molting
process finish. From the 35th day and onwards, feed only 70-80% of the feed
required.

Note: In the event of weather changes, such as heavy rain or extreme heat, reduce shrimp feed intake to only 70-80% of the required amount. To minimize the risk of adverse effects during molting, reduce the amount of food given to the shrimp, and increase it again after the molting process is complete. Starting from the 35th day, reduce feed intake to only 70-80% of the required amount.
