Increasing challenges

Shrimp farming: successful till the 30s

a Major source of livelihood/ profits

I0s major diseases begin to appear (e.g WSD) Major impact on livelihood of small-scale producers

Drugs & Chemicals (product quality)

Increasingly stringent standards

Declining prices Environmental degradation Allegations fot poor socio-economical sustainability

(WB, NACA, WWE, FAO, UNEP, .)

Epidemiological (population-based) investigations to identify risk factors for diseases

= DFID in Viet Nam and India (1997-2001)

= ACIAR in India (2001) Better Management Practices identified for India

BMP are practices that target:

= Environment protection

= Improved shrimp health/ production

= Improved food safety

Valid regardless of the species

or syste

Principles for

sustainable shrimp farming

Better Vianagement Practices

Good Aquaculture Practices

BMP history

= Gradual scaling up!

Several more projects:

m ACIAR in Indonesia & Thailand

m NACA, FAO, WWE in Indonesia (post-tsunami)

= NACA in Iran

(Sovernment of Viet Nam ACIAR BMP network

BMPs in India

Started in 2002 Government promoted (MPEDA) Aquaclubs (farmer groups)

Contract Hatcheries

Australian Centre for International Agricultural Research

BMPs in India

2003 62%

E Non-Demo

¢ Crop Calendar, Same time stocking with Efficient use of resources (feed)

Food safety & traceability

Source N.R Umesh, NaCSA Links with market

BMP in Viet Nam

(NÀCA)

Started in 2004

= Danida-funded project: 5 provinces

m NAFIQAVED developed GAP

Practices identified using experience from the region (India) & within VN

System specific, practical & atfordable by farmers

Working with small-scale farmers

Promote disease control, food safety & reduced environmental pollution

BMP in Viet Nam

m Semi-intensive farming

= Support farmers to:

m Prepare the pond better Check seed quality at stocking (WSSV, general health) Monitor pond bottom, water quality and shrimp health Improve biosecurity during production

Keep records

Better management of heath problems

(reduce chemical use)

= Support implementation at every level (also extension workers, local and national authorities)

BMP dissemination

Farmers meetings Regular pond visits

Training extension workers

Training volunteer Ext Workers

Promoting

larímnef øfOups

Collaboration

m™ Reduce costs: WSSV testing of PL

m Improve water management

m™ Reduce disease spread

Volunteer extension workers

m Key to BMPs dissemination

= Help other farmers

BMP implementation

Farmers accepted BMPs Evaluation at the end of cycle (questionnaire) Indicators of BMP implementation

m™ Removing soil before stocking

= Not ploughing if acid soil

a Testing PL for WSSV Result of BMP application m™ Reduced the risk of mortality (x1.4 to x1.7)

= Improved production per ha (x2 to x4)

= Doubled probability of making a profit

= Similar production to non-BMP

m Better quality (no antibiotics; tested for pathogens, )

= Better price by farmers

BMP tor broodstock suppliers BMP tor seed middlemen

BMP/GAP Harmonization

BMP in Viet Nam

(WWE)

Started in 2007

CaMau prov (1/4 production, 40% area)

= [raining for extension workers in farmer group

establishment & management

BMP in Viet Nam

Farmers’ benefits

[mproved production Better technical expertise

Increased bargaining power

—

—

= Better cooperation

—

Interest (farmers & local govt) to expand activities

Exploring challenges and opportunities for certification

(Shrimp Aquaculture Dialogue) Developing links with the market

= Collaboration with WWE Denmark & buyers

= BMP products are better

m Markets request better products (better price/market access)

Need for traceability! Possible if farmers are clustered

Use WWE influence on consumers / retailers
