View detailsShrimp black gill, black spot and fouling disease: treatment and prevention
Black gill, yellow gill, black spot and fouling usually originate from a dirty pond bottom and high toxic gases combined with bacteria, fungi and protozoa attached to the gills and shell of the shrimp. Treatment must first clean up the environment, then kill the attached agents, and then help the shrimp moult to replace the shell.
Typical signs
- Gills turning black, brown or yellow
- Black spots and lesions on the shell, broken antennae, tail rot
- Fouled shrimp with dirty shells and delayed moulting
- Shrimp surfacing in the early morning
Treatment steps
Increase aeration, treat the bottom and toxic gases
Kill bacteria, fungi and gill-attached parasites at treatment doses
Re-inoculate probiotics after 2–3 days
Add minerals and vitamin C to help shrimp moult

Frequently asked questions
Are shrimp with black spots safe to eat?
Black spots on the shell are not harmful to consumers but lower the value of the shrimp. Treat early so the shrimp moult and their shells become clean again.
Can fouling kill shrimp?
Heavy fouling makes it hard for shrimp to breathe, delays moulting and makes them prone to dying when oxygen is low. The attached protozoa need to be killed and the shrimp stimulated to moult.
