Stock Assessments Conducted
in 2015
• Species important to sport fisheries: – Yelloweye rockfish
– Black rockfish
– China rockfish
– Kelp greenling
Good news:
• TWO SPECIES DECLARED REBUILT
– Canary rockfish and petrale sole
• NO new overfished species

Canary Rockfish
• Declared “Rebuilt” in June 2015
– Higher ACLs go into effect beginning 2017
• PFMC may still be conservative in setting ACL
– Should still allow for increased allocations
– Yelloweye rockfish will limit how much canary can be accessed

Yelloweye rockfish
• Rebuilding date—2074
– Still on that track
• Coastwide ACL goes up from 19 mt in 2016 to 20 mt in 2017
– Will likely mean approximately 0.2 mt increase to OR recreational sector

Black Rockfish
• Assessed for first time since 2007
– State-specific assessments
– Previously OR and CA assessed together
• Stock is healthy
– Approximately 60% of unfished biomass
– Oregon ACL will likely be around 550 mt
• 2015 Oregon state landings caps= 580 mt
– 440.8 – Recreational
– 139.2 - Commercial

China Rockfish
• New full assessment
– Previously a data-poor assessment
• Will still be managed as part of the Nearshore Rockfish Complex
– Will increase the complex ACL by a small amount
– Expect similar allocation to 2015-16

Kelp Greenling
• New full assessment for Oregon only
– Stock is healthy, approximately 70% of unfished biomass

Update on Longleader Fishery
• NMFS and ODFW working on analysis
• Council should make final decision in March
• May take up to 6 months to get into federal regulations
• Implement in state regulations as soon as in federal regulations

Update on Longleader Fishery
• Intended to target midwater species
– Yellowtail and widow rockfish
– Some bycatch of blue and canary rockfish
• Will likely be allowed outside of the 40 fm regulatory line
• No retention of lingcod
– Minimize potential for yelloweye rockfish bycatch

Update on Longleader Fishery
18
Allows some opportunities
for ports without shallow
water reefs

Thoughts/Ideas from ODFW Staff
• Yelloweye rockfish and nearshore rockfish complex likely most constraining stocks
• With probable increase in canary rockfish allocation
– Look at increasing the bag limit
• Pro: Could take pressure off of other species
• Con: Concern over yelloweye bycatch

Thoughts/Ideas from ODFW Staff
• Allow flatfish fishing outside of seasonal closed area
– Access to underutilized stocks
– Don’t live in the same areas as yelloweye rockfish
20

Thoughts/Ideas from ODFW Staff
• Reduce or eliminate the minimum length limit for kelp greenling?
– Reach full length at young ages (100% mature at 11.8 inches; ~2 years)
– Few harvesting 10-11” fish currently

Thoughts/Ideas from ODFW Staff
• Reduce or eliminate the minimum length limit?
22
Did not have much effect on harvests:
• Very few people kept greenling < 10” before the size limit
• Even a 12” minimum size would have not much effect
(most harvest bigger fish)
