Future recommendations

3. Larval Stocking Received 60,000 Moyie Lake larvae from UIARI
Approximately 30 larvae placed in each net pen

4. Net Pens
Dimensions 0.91 m X 0.91 m X 1.83 m
500 µm mesh Nitex cloth

5. Larvae Released Into the Pond

6. Predator Assessment Yellow perch observed in pond Seine Gill net
Over 700 yellow perch removed

7. Yellow Perch Length Frequency

8. Light Trap Sampling Began June 6, 2008 Traps set at night
Measure and release burbot
One burbot caught outside of net pens

10. Tagging
VIE (Visible implant elastomer) tags (Northwest Marine Technology, Inc.)
Pink fluorescent
Left side just below first dorsal fin
1-3 mm long

11. Tagging
Low mortality observed
All burbot released into pond

13. Survival Preliminary results show 73% survival
Based on 60 burbot larvae released into net pens

14. Future Recommendations
Continue extensive rearing in 2009 using a pond devoid of fish
Use four net pens
