Swollen hindgut syndrome (SHG)
SHG does not show the mass mortality of Penaeus monodon larvae like WSSV disease.
- Shrimp seeds with normal hind gut have a swollen hindgut with or without melanisation. This condition is also referred to as hindgut expansion.
- In the affected seeds, the rhythmic movements in the rectal region are affected resulting in difficulty in expelling the faecal pellets.
- Bloated or swollen in hind gut area, with the posterior digestive tract convoluting through the last abdominal segment
- It has negative effects on digestion and excretion and significantly reduced the production of PL.
- Improving water quality
- Adding digestive enzymes to the feed by top-dressing; using newly hatched Artemia nauplii; using enriched Artemia nauplii.
- Reducing the use of antibiotics and MIC testing to select and use only permitted and effective antibiotics. (Antibiotics will only work against bacteria that are sensitive to that antibiotic, so shrimp hatcheries must be check first whether the problem is bacterial and then culture the problematic pathogen(s) and conduct sensitivity analysis with legal antibiotics to test the effectiveness of antibiotics before use).
We will suggest to use our Ecobio Probiotics for quick solution.
