Introduction of P. vannamei to Malaysia
P. vannamei was introduced into Peninsular Malaysia in 2001
from Taiwan Province of China and in 2002 from Thailand into
Peninsular Malaysia and a farm in Sabah (FAO, 2004/10).
Ban on P. vennamei culture
• Malaysia implemented an indefinite ban on
introduction of P. vannamei, effective 1st June 2003,
in effort to :
– Avoid introduction of exotic viruses (TSV, LOVV),
– Sustain the continuous development black tiger prawn
culture,
– Avoid existing competitors in global market,
– Avoid potential impact on biodiversity,
– Avoid illegal introduction of PL and brood stock.
The ban was officially lifted at the end of Mac 2005:
•
•
•
•
•
Availability of SPF P. vannamei broodstock
P. vannamei could provide economic benefits by reviving the idle farm
Capitalize opportunity to be a producer of white shrimp for the world
market.
Prevention of virus disease in P. monodon culture is still unresolved.
Protocols, guidelines and management practices for P. vannamei were
introduced to ensure the sustainability of P. monodon culture in the
country
Methodology
This study is based on:
Secondary data: annual statistics, reports, trade information.

SPF P. vannamei PL production in Malaysia
• 9 hatcheries
• Estimated capacity, close to 5 billion PL/year
• Department carry out regular monitoring on
nauplii and PL production and also supply to
farmers and other hatcheries.
Finding

Issue
1. Shrimp
production
To sustain P. monodon culture
P. vannamei was permitted to culture as an alternative to P.
monodon. Nevertheless it become substitute species to farmers.
42 % farmers interviewed were reluctant to shift back to P. monodon
culture.
Main reasons:
•
Disease infection (unavailability SPF broodstock)
•
Significant reduction in selling price
•
Higher cost of production

Finding
Impact:
2. Economics
Issue
To reduce import
To increase export
•
Regional trade with countries facing anti-dumping duties in
the US market growing significantly.
•
Import of fresh and frozen shrimp from China and Thailand
increased significantly from 2003 to 2004
•
Malaysia export of shrimp products to US increased
significantly from 2003 to 2004
Consequences
Impact:
1. Shrimp
production
Issue
To increase shrimp production from aquaculture
To sustain shrimp aquaculture
To sustain sustain P. monodon culture
•
Shrimp production from aquaculture is expected to increase
by two folds based on farm productivity. Existing 7,200 ha
culture area could easily produce 70,000 m.t a year.
•
Disease incidence could be increased since farmers have
low attitude on disease management
•
May lead to slow recovery of P. monodon culture in the
country
Consequences
Impact:
2. Economics
Issue
To sustain shrimp aquaculture
To increase export and reduce import
•
Excess supply of fresh shrimp from neighboring countries
lead price decrease and low profit margin.
•
Further expansion will lead further drop in price and increase
competition among neighboring countries.
•
Excess shrimp from neighboring countries may lead to
transhipment and repackaging activities which must be
eliminated to avoid the risk of imposition by US on antidumping duties.
Policy implication
•
Enhancement of the existing Aquaculture Extension
Programme – Encourage Best Aquaculture Management
Practices.
•
Implementation of Traceability programme – Issuence of
Certificate of Origin by the authorities.
•
Incentives to promote biosecurity principles in farm
operation.
•
Strict imposition on control of transboundry movement of
aquatic organisms, Quarantine Regulation, SPS measures
and Fish Health Monitoring Programmes.
Conclusion
The introduction of P. vannamei has given rise to positive
the industry based on the following findings
Impact on
• Shrimp production increased significantly
• Existing shrimp ponds are well utilized (few idle ponds)
• All the players in the industry are in business
• Affordable price of shrimp for consumers
• Shrimp production target is within reach
However much care is needed to avoid disease outbreaks due to improper
farming practices and strict regulatory measures to be imposed on
quarantine measures and to prevent transhipment and repacking to avoid
imposition of anti dumping duties
