Introduction
• Tilapia are one of the most
important domesticated fish today.
• Tilapia will be the single most
important aquaculture product in
the 21st Century
Current Status
• Production widely distributed
around the world.
• Grows well in most production
systems.
• Established market demand.
• Popular in several product forms.
Production widely distributed
around the world.
• FAO reports production in 85
countries.
• East Asia, Indonesia, Latin
America, Caribbean, Middle East,
and Africa
• Germany, Belgium, Spain, Canada,
Korea, Japan, most states in US
Production widely distributed
around the world.
• Wild catch being replaced by farm
raised
• Used in many cuisine, hundreds of
recipes
• Tilapia, boulti, pla nil, St. Peters
fish
Grows well in most
production systems
• Ponds
• Cages
• Raceways, round tanks,
recirculating systems
• Ranching (lake releases)
• Freshwater, Brackish water,
Estuarine, and Marine
Grows well in most
production systems
• Polyculture with shrimp, catfish,
carp
• Herbivorous and /or omnivorous
• Good growth in fertilized ponds
• Many byproducts can be used in
prepared feeds
Grows well in most
production systems
•
•
•
•
•
Simple hatchery technology
Disease resistant
Grow well at high densities
Several color variants available
More “domesticated” than most
aquaculture crops
Established market demand
• Accepted in many national dishes
• Popular in many forms
• Live, Whole, fillets, fresh and
frozen, smoked, surimi
Problem areas
• Low fillet recovery rate
• Slow growing females
• Off-flavors
Advances and Solutions:
Low fillet recovery rate
• Selective breeding programs
• Transgenics - Growth hormones
• Growth enhancers - Bovine
Somatotropins
• Better processing equipment
Advances and Solutions:
Slow growing females
•
•
•
•
•
Methyltestosterone
Genetically male tilapia
All male hybrids
High density culture
O. niloticus with larger females
Advances and Solutions:
Off-flavors
• Depuration systems
• Control of blue-green algae
• Production in system with limited
access to benthic algae
Why tilapia will surpass other
species in importance.
• Production constraints being
reduced, and costs decreasing
• Markets are still expanding
• Market prices holding
• More training & experience of
growers, processors and marketers
Why tilapia will surpass other
species in importance.
• Ecologically sustainable
• Popular with environmentalists
• Consumption not restricted by
religious observances
• Mild flavor preferred by many
consumers
Why tilapia will surpass other
species in importance.
• Carp: markets are limited
• Salmonids and shrimps need high
levels of fish meal, limited
ingredients for diets
• Most other species need higher
water quality, competition for sites
Current Trends
• Increase in demand for all forms of
tilapia
• Demand increase will be greatest
for fresh fillets
• Prices have been constant for
several years and are likely to
remain stable
Current Trends
• US and EU growers will
concentrate on live sales and
highly processed forms
• Southeast Asia and Latin America
will be primary US suppliers
• Africa, Latin America and
Caribbean will supply EU
