Red Crab - #2 Deep-Sea Red Crab Specification Package for Fishing Years 2014-2016 SSC Meeting Presentation Red Crab PDT August 21, 2013
Previous SSC Recommendations • April 28, 2010: • Given data-poor condition of assessment, there is insufficient information to estimate MSY or OFL for deep-sea red crab • Interim ABC should be based on long-term average landings of males • Landings should be limited to 1,775 mt males • Interim ABC based on long-term average landings is safely below an overfishing threshold and adequately accounts for scientific uncertainty
Previous SSC Recommendations • June 23, 2010: • Sustainability of future landings at or below the recommended ABC is conditional on not exceeding past discard rates • Inclusion of dead discards in red crab catch limits requires improved monitoring of the magnitude of discards and research on discard mortality
Updated Landings Information 2010-2012 landings were lower than Total Allowable Landings (TAL) limit • 2010-2012 landings are consistent with average landings since 2000 • Market-driven fishery, landings reflect market demand (J. Williams) •
Updated LPUE Information LPUE data interpreted from VTR reports using same method as • developed in 2006 LPUE appears stable in 2010-2012 and shows an increasing trend since • 2007
Updated Port Sample Information 2011 Port Sampled Carapace Width 1 2 3 2010-2012 mean size of landed males is consistent with average landed • size since 2001 (2011 sampling included landed females) Differences in landed size between three fished areas, reflecting market • demand in southern region of fishery
Discard Information No new method to determine dead discards • VTR-reported discards range from 5-1000% of landings • Low level of at-sea monitoring in red crab fishery • Ongoing research to improve estimates of discard rates and discard • mortality – Conducted cooperatively by Imam Syuhada and Joe DeAlteris (URI) and Jon Williams – Comparison of size distribution in 2003-2005 and 2010 tagging studies with 2012-2013 port sampling – Length-Based Catch Curve Analysis to estimate the level of fishing mortality that would explain the observed size frequency distributions for male and female crabs
Economic Impacts Fishing Year Landed Weight Price per Pound Revenue 2002 4,673,214 $0.86 $4,004,752 2003 4,091,659 $0.85 $3,491,683 2004 4,930,204 $0.94 $4,617,380 2005 4,079,670 $0.90 $3,661,860 2006 3,841,577 $0.90 $3,474,953 2007 2,771,501 $0.92 $2,557,421 2008 2,857,162 $1.01 $2,876,510 2009 2,773,776 $0.96 $2,612,782 2010 2,743,868 $0.97 $2,669,185 2011 3,343,902 $0.97 $3,253,621 2012 2,898,962 $1.00 $2,898,962 Average 3,542,318 $0.93 $3,283,555 • 2010-2012 prices slightly above average • No direct or indirect economic impacts from status quo 1,775 mt TAL
PDT Analysis • Updated landings, LPUE, port samples do not indicate any signs of stock decline • No update to assessment since Data Poor Working Group (2009) • Insufficient information to determine OFL, MSY • No new method for discard estimation • No direct or indirect economic impacts from status quo catch • PDT consensus for status quo interim ABC of 1,775 mt males Total Allowable Landings (TAL) for fishing years 2014-2016
