Herring Committee MeetingOctober 20, 2016
2
• Review updated analyses to support the initial range of alternatives recommended by the Council for alternatives to address localized depletion (LD) and/or user conflicts.
• Review initial PDT discussion of fishery overlap metric
Agenda Item
3
1. The AP motion that would close waters within 6 nautical miles from shore in Area 114 between June 1 – Aug 31 to all Atlantic herring vessels;
2. A year round closure of Atlantic Herring Management Area 1A (MWT gear only);
3. A 12 mile inshore closure year round south of Atlantic Herring Management Area 1A (i.e., within Areas 1B, 3 and 2) (MWT only);
4. A 25 mile inshore closure year round south of Atlantic Herring Management Area 1A (i.e., within Areas 1B, 3 and 2) (MWT only);
5. A 50 mile inshore closure year round south of Atlantic Herring Management Area 1A (i.e., within Areas 1B, 3 and 2) (MWT only);
6. Close 30 min squares 99, 100, 114, 115, 123 year round (MWT only)Without objection it was clarified that a seasonal component could be considered in any of the year-round alternatives above, to be defined later after monthly data available.
Initial Council LD alternatives (Sept 2016)
Maps of alternatives
4Alts 3‐5 exclude Area 1A
Preliminary Analysis of LD alternatives
1. General maps with herring landings in FY year blocks (2001-2005, 2006-2010, 2011-2015)
2. Herring landings by month – same FY blocks3. Impacts on fishing behavior as a result of closures
- Other fisheries - Bycatch
#1 and #2 mostly completed; #3 in the future, And monthly maps hopefully in the near future
5
Methods and Data
NEFSC Heat maps - database of all VTR points informed by observer data to define estimated area fished per VTR point (DePiper, 2014)
Maps - all VTR trips with >0 kept herring Tables and Figures - herring landings inside or outside
of various alternatives Compute landings in MT and percentage by month

Alt.1 6nm in Area 114 June-Aug Compared to All Herring Landings
• Landings in this area have shifted seasonally over time
• Largest effect would be in May (16% of all landings (1B fishery)

Initial PDT input On 9/7 the PDT provided initial feedback and identified a few
issues for the Cmte to clarify further- may want to seek Enforcement Cmte input- ability to combine alternatives?
On 10/4 the PDT discussed data needs for the overlap analysis: what time periods, fisheries, and areas should be used? The PDT needs more input from Cmte to clarify the problem these measures are trying to address.
– is the user conflict herring fishery wide, or gear specific (MWT)? - is the user conflict more current or more historic? - what are the primary fisheries experiencing the user conflict?- are there specific areas/times user conflicts are more prevalent?
22
Fishery Overlap Metric PDT has discussed the idea of a fishery overlap index Two specific formulas being considered that would calculate
the degree of overlap. PDT plans to start with fleets in NEFSC VTR database (herring
vs. gf species that eat herring – cod, pollock) Tuna info – HMS office has provided monthly commercial
catch by reporting area. May be able to improve with stakeholder input. Fallback – seasonal overlap
Striped bass – both commercial and recreational maps could probably be created – some important caveats. Is user conflict primarily boat trips or shore fishermen?
Whale watching – other?
23
Initial Tuna work HMS Office has sent commercial tuna landings from 1996-2015 Summarized by reporting area and month Very coarse comparedto herring reportingAreas - limitations
