Why aquaculture?

• 4eclining fish populations in the )ild

• 0ear5round supplies

• Specific qualit! and appearance

• 6ot enough )ild trout and catfish

to meet demand

Aquaculture &s" 'ild har&ests%

• Toda! the! are in competition.

• In the future aquaculture ma! permit

%etter managing of )ild resources tosustain long5term harvests.

• 2atcher!5raised fish )ill help to manage

man! commercial fish species.

(o' is aquaculture demand

li)e to increase?

• If consumers see fish as part of meat

protein comple7

• 1a! %e some shift to fish from otherproteins

7/17/2019 ac001ill


What about cost?

• Increased production efficienc! could

reduce prices.

• "elative costs of %eef, pork, chicken andfish affect consumer purchases.

7/17/2019 ac001ill


Feed con&ersion rates%

• Fish are t)ice as efficient as chickens.

• Possi%le transgenic research+• nhanced gro)th rate

• 3ater temperature tolerance

• 4isease resistance

• Caution is in order until long5term impacthas %een studied
