How to select a high quality shrimp food stock



 
High quality shrimp feed usually has the following characteristics. In this article we will help you choose the most quality shrimp food stock.


 – Even in terms of size, shape and color
– Smooth edges
– Clean
– Smooth appearance
– Nice Fragrant

– Does not dissolve in water after 3 hours
– Does not contain impurities such as glass, sand, mold, damp …
– Food must attract shrimp to prey
We should only feed shrimps when they really want to eat and prevent the accumulation of leftovers in the pond.
 “In general, we have to look at food as an asset before spreading it down to the pond, which is also a risk if left in the pond after 3 hours.”
Shrimp’s eating behavior
 Black tiger shrimp and white leg shrimp are both carnivores and are gluttonous like other crustaceans. It uses tactile senses to look for food and minerals to grow, proper pH that helps blood circulation and digestion. The habitat affects the body of the shrimp, such as: appetite, metabolism, moulting, digestion and immune system. Shrimp feeding should be considered based on shrimp characteristics such as short bowel movements, continuous movement and aggressive behavior.
 Feeding depends on the pond environment
 Some environmental factors affecting pond water affect shrimp feeding. In that, dissolved oxygen and water temperature are the two main factors that need attention. Shrimp decreases feeding when dissolved oxygen levels are lower than 4 ppm and stop eating when less than 2 ppm. The most suitable water temperature is 28 – 30oC. Each time the temperature drops by 2oC, the amount of food should be reduced by 30% compared to the average food intake. Should check the water temperature in the pond before feeding shrimp. If dissolved oxygen and water temperature are not appropriate, wait until sunlight is shed for at least 1 hour before feeding shrimp for the first meal of the day. At this time the dissolved oxygen content is ideal.
 Effects of high temperatures
 The time that the food in the intestines of the shrimp will change with the pond water temperature. As the water temperature rises, shrimp will eat faster and will also excrete faster than low temperatures. Farmers need to strictly control feed intake by feeding in the guidelines in the summer and should extend the interval between feeding in the cold season.
Water movement
 As shrimp often swim upstream, farmers need to spread food in the flow of water. Shrimp will move along the feeding area quite wide, food should be spread evenly and thinly in these feeding areas. This is reasonable to avoid spreading large amounts of food in a small area. This is also the cause of uneven shrimp size. Proper feeding will allow the conversion factor to be low and at the same time provide good water quality.
