Abstract
The bluefish (Pomatomus saltatrix) is an important marine fish species on the East Coast of the United States. They are popular amongst fishers, and are targeted both recreationally and commercially. Since 2005, the assessment of bluefish has been conducted via age structured assessment methods (ASAP). Concerns have been expressed about the adequacy of age information to assess this species. In an effort to help resolve these problems, the New Jersey Division of Fish and Wildlife initiated a pilot voluntary biological collection program in 2010. A number of sampling strategies was used to sample the recreational fishery, including: collections from volunteer anglers, fishing tournaments, party boats, and opportunistic collections associated with fishery-independent sampling programs for non-bluefish species. In 2010, otoliths were extracted from 219 bluefish harvested from a variety of locations in NJ between April and November. Thus far in 2011, otoliths were extracted from 214 bluefish. Comparison of the 2010 size frequency of bluefish from New Jersey with the coastal 2010 ALK shows that while there was some overlap, samples were often complementary but ALK gaps remain even when all data are combined.
2. • Jointly managed by ASMFC and MAFMC
• 1st Fisheries Management Plan (FMP) adopted in
1989
• Commercial Fishery
• Quota management
• Recreational Fishery
• Annual recreational harvest limit
• Daily possession limit
3. • 2005 – Age structured stock assessment
• June 2009 – Bluefish TC discussed need for
additional age samples
• February 2010 –NJ’s bluefish management board
member proposed that NJ would begin a voluntary
collection program
• May 2010 – NJ DFW began collecting samples
Steve Luell
6. • In August 2011, ASMFC proposed that the
states where at least 5% of the total bluefish
harvest were landed between 1998 and 2008
should be required to collect at least 100 age
samples per year
• If approved, the addendum will be
implemented in January 2012
7. • Samples were collected from a variety of sources:
• volunteer recreational anglers
• recreational fishing tournaments
• head boats
• fishery independent sampling for
non – bluefish species
8. • Information recorded when sampling:
• Whole lengths and rack lengths (when possible)
• Weight (if possible)
• Date
• Location
• Type of fishery
• Otoliths for aging
• Whole and rack length comparison

16. • Program is successful
• Cost effective – about $6000 / year
• ALK gaps remain
• Rack collection is feasible
• Provides useful model for other states to follow
17. • Continue sampling program
• Age otoliths
• Bluefish will next be peer reviewed at SARC 57 in
December 2013
