WP 6:
Economic evaluation of breeding programs
First step:
Review of selective breeding programs and
their market share

Objectives
1. Characteristics of breeding companies
2. Market share of selective breeding in European
production
3
Six species account for >95% of European
aquaculture production
Common
European carp
Turbot
Rest = 3%

Approach
 Survey among breeding companies
● Family or mass selection
&
● Traits
● Selected generations
● Egg/juvenile production
 Market share = Production by breeding companies
European production
5
Characteristics
 7 Breeding companies
 All perform family selection
 Typically selected traits:
● Growth
● Processing yield
● Product quality
● Disease resistance
 Selected for +10 generations

 Most commonly selected traits:
1. Growth
2. Morphology
3. Disease resistance
4. Product quality
5. Processing yield
