Shrimp feed is one of the very important factors that determine the development of shrimp as well as the profit when trading shrimp. Many people, because they do not have full understanding, have fed shrimp with food sources that lack the rationality in dosage, regimen, and nutrients, which has caused some unnecessary problems: stunted shrimp, crop failure. , mass death, etc. Therefore, when feeding shrimp, it should be noted that food for shrimp must ensure the following conditions:
Choose food for shrimp based on sensory and feed size
Choosing food for shrimp based on sensations
When looking to buy food for shrimp, look for foods that have the right color and characteristic smell.
The correct color range is from a deep golden brown to brown. Lighter or darker colors can potentially cause disease in shrimp.
The standard characteristic odor of shrimp feed is the smell of the feed ingredients. If shrimp feed has a strange smell, chemical smell, musty smell, etc., it should not be purchased. If necessary, immediately report to a nearby medical facility or food safety facility for inspection and assessment, to avoid endangering future customers.
Choose food for shrimp based on size
Shrimp feed can be in three forms: pellets, flakes and flakes. The common point of these three types is that they are not lumpy and have a certain uniformity.
For pellets, there are 6 types commonly used for the stages in the development of shrimp.
Black tiger shrimp:
- 0.01 – 0.2 g/head
- 0.2 – 1 g/head
- 1 – 5 g/head
- 5 – 10 g/head
- 10-20 g/head
- More than 20 g/head.
White leg shrimp:
- 0.1 – 1 g/animal using feed size less than 0.6 mm
- 1 – 3 g/head, maximum feed size 0.8 mm
- 3 – 8 g/head, feed less than 1.2 mm
- 8 – 12 g/head, maximum size 1.8 mm
- 12 – 20 g/head, maximum feed size 2.2 mm
- Greater than 20 g/head, maximum feed size 2.5 mm.
The ratio of length to diameter of feed pellets is about 1.5 to 2 times.
When shrimp weight is at 0.1 to 8g, shrimp feed can be in two forms simultaneously: flakes and pellets. However, when shrimp reach weight over 8g, people should only feed shrimp pellets. Especially those with cylindrical shape, the surface of the pellets is smooth, and the size corresponds to the ability of shrimp to eat.
The granules of the flake food must be even, fine and fit in the mouth of the shrimp
Shrimp feed must have crumbs according to certain criteria. The crumb rate is less than 1%. If the shrimp feed when purchased does not achieve the desired crumb, you should use a sieve to filter the larger pellets and proceed to crush the remaining large pellets.
Choose food for shrimp based on the durability of the food
How to test the standard durability of shrimp feed:
- Take about 5g of shrimp food and put it in a glass containing clear water.
- Let the shrimp water cup stand for a few minutes.
- Every 15 minutes, use a chopstick to stir gently and evenly, then observe what happens in the cup of water.
- The food is durable, which means that the food after being soaked in water for a long time retains its original shape and does not break when taken out of the glass.
- Low-strength foods will dissolve or break when taken out of the glass.
Note: It is recommended to test the durability for only 2 hours to get the results according to the standard
