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

CONCLUSIONS

25

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
