SHRIMP INDUSTRY CHALLENGES
3
• In 2017, focus on seed quality and disease-free broodstock
• In 2018, focus on banned chemicals, international price and production cost (feed)
• In 2019, focus on production cost (feed) and disease-free broodstock
ISSUES WITH PRODUCTION COST
4
How to handle production and feed costs?
Many consider reducing investment in
Biosecurity
Products/protocols
PL price (hence lower quality)
Feed cost (hence lower quality)

ISSUES WITH PRODUCTION COST
5
How to handle production and feed costs?
We believe in improving production
efficiency:
Lower risk of disease
Stronger PLs
Cost benefit of products/protocols

Genetics: selection for growth and robustness

Good production comes from strong and healthy PLs
Broodstock:

Different designs for different objectives
• Focus on growth
• Focus on biosecurity and consistency
• Focus on farm crop rotation

CONCLUSIONS

How to cope with feed cost issues?
Focus on production efficiency and predictability
- Shrimp genetics and maturation
- Hatchery and nursery protocols
- Cost effective use of health booster and quality feed
- Adapted rearing protocols
