6. Introductory Stocking Introductions of non-natives

7. Enhancement Stocking Maintenance - recruitment failure Supplemental - augment natural recruitment

8. Why Stock? Introduce new species (sport, commercial) Introduce new forage Biological control Start/maintain put- grow-take fishery Supplement year- class Satisfy public, political pressure

9. Why Stock? Mitigate “situation” Start/maintain put- take fishery Re-establish extirpated species Establish trophy fishery Increase angler satisfaction Redistribute fishing pressure
