What is Prawns Jejunum?

When the P.vannamei shrimp has problems in digestion/absorption, they would easily to be sufferred from Jejunum. You may ask what the Jejunum is, actually, we can find that the shrimp’s stomach and intestines have no feed or things in shrimp farming, they are empty. However, there is “M” shape in the normal shrimp intestine with clear visible of gut and pancreas.

What are symptoms of the jejunum?

1. Bacterial Disease or Eaten Dead Shrimp result to Red Stomach;

2. Intestinal thickening and edema of prawns;

3. Feed reduction during shrimp pancreas conversion can easily lead to intestinal rupture.

4. The jejunum usually lead to white spots, red bodies, reddening of appendages, white turbid muscles, and redness in the digestive tract.

What causes prawn jejunum?

1. Weather

High-temperature weather causes severe hypoxia in water quality, insufficient oxygen will cause stress response to shrimp, feed intake will decline and jejunum will appear.

2. Poor constitution of prawns during molting.

3. Pathogenic bacteria

Vibrio is also the main cause of the jejunum. Vibrio destroys intestinal cells, reduces shrimp feeding, and causes jejunum.

4. Harmful algae

Algal toxins produced by cyanobacteria, etc., damage the digestive system of shrimp.

5. In regular adding liver protector products.

Bile acid is added to the feed to protect the pancreas and intestines, improve the survival rate, and reduce the incidence of jejunum.
