What are the prawns fed with liver transfer?

Generally, shrimp has been cultured for 18 days (medium or late shrimp for 15 days), and the seedlings have grown to 3-4cm shrimp. At this time, the liver development enters the liver transformation stage, which is the most important period for the liver function of shrimp to be sound. So, what is the shrimp liver feeding?

First, shrimp liver feed what?

Shrimp liver transfer can be properly fed with some animal feed, such as rotifers, hammered snails, mussels and scraps of the slaughterhouse. Some phytoplankton can also be added, such as diatoms, gymnoalgae and so on. In addition, bitter grass and verticillium verticillata can be used as both habitat and natural bait during the liver transformation period of shrimp.

Second, what are the main factors affecting the liver of prawn?

① Pond Environment:

The toxic and harmful substances produced by the deterioration of water quality and sediment (such as ammonia nitrogen, hydrogen sulfide, nitrite, methane, heavy metals, etc.) directly damage the liver of shrimp, reduce the defense ability of the liver, and cause a variety of diseases.

The nutrients required by ② liver are insufficient:

Such as fat, protein, sugars, vitamins and other nutritional deficiencies or imbalance will affect the normal growth and function of the liver, the normal metabolism of cells is blocked, the liver is prone to pathological changes.

Antibiotics, disinfectants and insecticides can directly damage the liver.

④ bacteria and viruses:

The toxicity of germs and viruses to the liver and even the whole body is devastating, such as white spot disease, yellow head disease, peach disease, Vibrio fluorescens and so on.

Shrimp liver transformation period is an important period for shrimp growth, when they feed faster, it is necessary to pay attention to the regular feeding of a small number of meals.
