Shrimp eat enough but don't grow, FCR keeps rising without clear reason?
Slow growth isn't about feed quantity. It's mostly poor absorption, liver dysfunction, or silent stress. Fix the root cause to gain weight.
Weak appetite and slow growth in shrimp isn't about feed quantity — it's mostly poor gut absorption, liver dysfunction, or silent EHP parasitism. Fix the root cause with CANFORTA (appetite vitamins), ACTISEL (live yeast for digestion), CALPHOS GRO minerals (uniform molting). If EHP suspected → add FLASH + AQUAMOS.
Quick Summary
Main Causes
- Weak gut
- Silent EHP
- Micronutrient deficiency
Signs
- lacking enzymes, poor absorption despite adequate feed
- parasitizes liver, shrimp eat but can't absorb
- minerals, vitamins insufficient for molting and growth
Solutions
- Add CANFORTA 5-7ml/kg
- Use ACTISEL 3-5g/kg
- Add CALPHOS GRO or CELL CANPHOS GOLD minerals
Why are shrimp vulnerable?
Weak gut — lacking enzymes, poor absorption despite adequate feed

📖 Read article →Micronutrient deficiency — minerals, vitamins insufficient for molting and growth
📖 Read article →Environmental stress — continuous pH/alkalinity/temperature fluctuation

Stabilize → Cut pathogen → Recover internally
Add CANFORTA 5-7ml/kg — high-absorption vitamins, fast appetite stimulation
Use ACTISEL 3-5g/kg — live yeast improves digestion, better absorption
Add CALPHOS GRO or CELL CANPHOS GOLD minerals — uniform molting stimulation
If EHP suspected — use AQUAMOS + FLASH for resistance support
Check liver — if pale, supplement with HERB GUARD for protection
Expected Results
Acute symptoms reduce, shrimp stabilize
Clear improvement, shrimp resume eating
Full recovery, maintain with regular probiotics

VIMIXFrequently Asked Questions
Why do shrimp eat enough but don't grow?
Most common cause is weak gut — insufficient digestive enzymes lead to poor absorption despite adequate feed. Or EHP parasitizing the liver steals nutrients. Use ACTISEL to boost digestion + PCR test for EHP.
What is normal FCR for white leg shrimp?
Good FCR for whiteleg shrimp: 1.1-1.3 (intensive farming). FCR above 1.5 requires checking gut, liver, and pond microbiome. Use CANFORTA + ACTISEL to improve absorption, reduce FCR.
What causes uneven molting in shrimp?
Usually mineral deficiency — calcium, magnesium, phosphorus insufficient for molting. Add CALPHOS GRO or CELL CANPHOS GOLD every 3-5 days. Check water alkalinity, maintain 120-150 ppm.
How is live yeast ACTISEL different from regular digestive enzymes?
ACTISEL contains live Saccharomyces cerevisiae yeast — self-produces digestive enzymes in the shrimp gut, improves gut microbiome. Regular enzymes only supply external enzymes with shorter-term effect.
When should vitamins be supplemented for shrimp?
Add CANFORTA when: (1) weak appetite, (2) after rain/stress, (3) before and after molting, (4) after antibiotics. Dose 5-7ml/kg feed, mix for 5-7 consecutive days.
