COMMON BROODSTOCK ISSUES

1
COMMON BROODSTOCK ISSUES

• Biosecurity a major concern more then one
  broodstock
• Short term
• Nutrition
• Health management (screening)
• Long term
• Genetic selection
• Sex determination (sablefish)
• NA markers. Can determine parentage on per egg
  basis.

2
JUVENILE PRODUCTION

• Short term
• Larval survival (feeding/enrichments)
• Improve technology
• Deformities (sablefish)

3
JUVENILE PRODUCTION

• Long term
• Improve husbandry
• Fish health management
• Temp, salinity, light (sablefish)
• Not a problem for wolffish (transfer from Norway)

4
Nursery

• Short term priority for cod, halibut (?), haddock
  (?)

5
CAGE ONGROWING

• Short term
• Feeding strategies
• Diets
• Grading
• Fatty liver (haddock, cod)
• Health management

6
CAGE ONGROWING (cont)

• Long term
• Early maturation
• Feed delivery
• Environmental interactions
• Fillet quality

7
WOLFFISH

• Broodstock issues similar
• Juvenile production OK
• Requires tech transfer and pilot scale
  partnerships b/w Norway/Quebec/NL
• Needs industrial partners govt supported
• Need more then one production site
