  2. Objectives – Large fish sampling • Acclimate to LTM • Work out sampling logistics • Optimize sampling effort for LTM • Identify optimal ageing structures • Estimate size-selectivity, bias from Rosa Lee phenomena. • Identify other needs for LTM

  3. Species distribution

  4. Standard population assessment gear • Summer trap netting (BLG, PMK, RKB, and BLC (August only)) • Summer gill netting (NOP, TLC, LAT, BLC, RKB, WAE, YEP, WTS) • Ice-out trap netting (NOP,LAT) • Spring or fall electrofishing (LMB, SMB)

  5. Belle Lake trap nets 101% 101% 129% 142% 70% 167% 171%

  6. Belle Lake trap nets 101% 101% 129% 142% 70% 167% 171%

  7. Gill net mortality on NOP(age 2 and older)

  8. Belle Lake gill nets 35% 42% 67% 92% 88% 181% 150% 300% 224%

  9. Belle Lake gill nets 44% 81% 64% 39% 38% 63% 50% 60% 63% 104%

  10. Ice-out trap nettingNorthern pike

  11. Belle Lake spring electrofishing

  12. Size-selectivityLMB (spring electrofishing at night)

  13. Other sampling • Age 0 sampling (small mesh TN; electrofishing) • Mark-recapture (ice-out netting) • Hydroacoustics • Angling • Other ideas?

  14. Age structure comparison • All target species except BLC (LAT?) • Compare ages estimated with otoliths, scales, fin rays (WTS, NOP), and dorsal spines (LMB, SMB, WAE?) • Specialists: Calub Shavlik (BLG), Mike Habrat, T.J. DeBates, Joe Stewig (NOP, WTS) • Broader applicability than just LTM
