Overview
 Strong
local production of tilapia and shrimp
 How to further expand exports in weak
economy
 Improving sustainability (environmental and
economic)
 Earn NGO certification(s) (WWF, GAA-ACC,
Whole Foods, NaturLand, etc.)
 Find and develop market niches
Gaining NGO certifications
 NaturLand
 World
Wildlife Fund
 Aquaculture Certification Council
 WWF , ACC, and Whole Foods have
released draft sustainability guidelines (Best
Aquaculture Practices) for public comment
 Each reviewing sustainability of aquaculture
practices and providing a certification and
marketing logo
Basic goals of NGO’s
environment – reduce effluent impacts,
protect wildlife, mitigate damage
 Protect consumers – reduce (eliminate)
hormones, antibiotics, contaminants
 Protect workers – safe environment, fair wages,
follow local labor laws and rules
 Protect society and farm neighbors – follow
local laws and land tenure, reduce environmental
externalities
 Protect
Best Management/Aquaculture Practices
affecting quality control and markets
 Improve
water supply and discharge quality
 Feed supply (no contaminates: melamine,
heavy metals, aflatoxins, or anti-biotics,
hormones, etc.)
 Algae control to avoid off-flavor or toxins
 Control parasites that might scar skin or
impact fillet
 Bird control (environmental issue, loss of
stocks, vector for parasites and disease)
Merging the best of the Green and
Blue Revolutions : Integrating
aquaculture with agriculture
Reuse of aquaculture effluents
improving sustainability
Revolution – huge increase in food
production, but heavy reliance on irrigation,
fuel and fertilizer
 Blue Revolution – almost 50% of seafood is
farm raised, but many environmental
impacts (effluents causing eutrophication,
algae blooms, cage and raft conflicts with
other users in oceans, bays and lakes)

Historical perspective
 Traditional
farming around the world integrated
livestock and crops
 East and South Asian farmers have long
tradition of integrating agriculture and
aquaculture
 Asian sustainable farming systems support huge
populations
 Fish – vegetable – rice (complex carbohydrate)
diet is recommended by most nutrition experts
Historical perspective
 Modern
agriculture cannot follow Asian
model of small-farm integrated systems
(gardening)
 We need an industrial version merging
aqua- and agri- cultures utilizing high
technology
 Taking the best of the Green and Blue
Revolutions
Green Revolutions weaknesses are Blue

Salmon and tuna – seaweeds, inverts
 Salmon
and tuna
cages release
dissolved nutrients
(N, P, K, Fe, CO2,
etc.) and
suspended solids
(feed, feces,
phytoplankton) to
be consumed by
seaweed, bivalves,
and sea urchins
Marine fish – seaweeds and bivalves
Fish cage effluents
(feed and feces)
fertilize seaweed and
feed filter feeding
bivalves
Abalone and seaweeds
 Abalone
require
fresh seaweed in
diet. Many farms
rear seaweeds in
abalone farm
effluent.
Sustainable marine farming
 Follow
Oriental farming model of animal
wastes fertilizing plants.
 Add invertebrates that filter feed and graze
on detritus
 Organize aquaculture system to balance
nutrient flows and market demands
 Provide highest quality products while
protecting the environment
Tilapia example
 Fast
growing aquaculture product
 Minimal environmental or social impacts,
but still want to improve
 NGO’s working with industry to develop
certifications
 New markets, new products, reduce impacts

2007 US Tilapia Sales estimate –
$559,788,809 + $50,000,000 =

Processing and Best Aquaculture
Practices
 Best
Aquaculture practices extend to
harvest and transport
 Inside the processing plant
 Reuse of wastes
ISO 9100 and ISO 22000
 ISO
9100 provides for certification of
Hazard Analysis at Critical Control Points
 Covers product safety, plant and food
hygiene, economic integrity, and product
quality.
 ISO 22000, food safety management
system, applies to all kinds of food
processors linked to CODEX
Alimentarius
HACCP
 Hazard
Analysis at Critical Control Points
 Planning procedure for documenting good
production and processing practices
 Participants operate under approved plan with
audits at random frequency
 Focus is on documentation of proper activities at
important stages rather than stationing a
permanent inspector at farm or processing plant.
 Greater focus on critical processing steps.
 More cost effective
HACCP - Examples:
 Document
feed source and use, farm water
quality, testing for off-flavor
 Document source, arrival time, temperature
and condition of fish as they arrive at
process plant
 Provide footbaths, hand washes and
protective clothing for processing workers,
document usage by having employees sign
daily log
 Measure and record bacterial numbers on
fillets during quality control
HACCP
 First
step is to write the plan
 Second step is plan review by authorities
 Third step is to train all employees in
HACCP plan procedures and
documentation
 Fourth step is to operate plant according to
the approved plan
 Fifth step is to maintain paperwork
documenting all stages until inspection
Quality control - bacterial testing
Samples should be
checked for bacterial
contamination
 Follow HACCP
procedures and EU
guidelines
 NGO’s may add
additional criteria

Recommendations
1. More integrated farms using effluents for
irrigation of plant crops
2. Industry-government-NGO partnerships to
implement BMP/BAP’s
3. Processing plants – develop and follow HACCP
plans and implement and obtain ISO certification
4. Industry develop additional by-products (leather,
fish sticks, etc)
What’s needed next?
 Trained
production/farming staff
 Trained regulators and bankers who
understand aquaculture
 Incorporate best technologies of agriculture
and aquaculture
 Economies of scale
 Governmental consideration for zoning and
leasing
 Eager customers who want to buy aquatic
products
