📉 Weak Appetite — Slow Growth — High FCR

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- amino acid), Pro Gut (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 Pro Gut 5g/kg
  • Add CALPHOS GRO or QUICKSHELL GOLD minerals
Treatment

Complete 5-step protocol

Stabilize → Cut pathogen → Recover internally

1
Appetite boost

Add CANFORTA 5-7ml/kg — high-absorption vitamins, fast appetite stimulation

2
Boost digestion

Use Pro Gut 5g/kg — live yeast improves digestion, better absorption

3
Molting support

Add CALPHOS GRO or QUICKSHELL GOLD minerals — uniform molting stimulation

4
Anti-EHP

If EHP suspected — use FLASH for resistance support

5
Liver protection

Check liver — if pale, supplement with HERB GUARD for protection

Results

Expected Results

1-2 days

Acute symptoms reduce, shrimp stabilize

3-5 days

Clear improvement, shrimp resume eating

7-14 days

Full recovery, maintain with regular probiotics

Frequently 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 Pro Gut 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 + Pro Gut to improve absorption, reduce FCR.

What causes uneven molting in shrimp?

Usually mineral deficiency — calcium, magnesium, phosphorus insufficient for molting. Add CALPHOS GRO or QUICKSHELL GOLD every 3-5 days. Check water alkalinity, maintain 120-150 ppm.

How is live yeast Pro Gut 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.
