Getting conflicting reports about hook spacing on the LL sablefish survey. Looks like it has varied over time and between area, and sometimes within a year and area. I'd like to keep this issue open until resolved.
Aaron Baldwin:
CLARENCE STRAIT: 118” hook spacing from 1988-1996, in 1997 it was 72", in 1998 & 1999 it was 64", them 2000 to present it was 78". (ALEX trip set ups)
CHATHAM:
1997 – 78.7”
1998 – 78.7”
1999 – 78.8”
2000 – blank
2001 – 78.7”
2002 – 78.7”
2003 – 78.7”
2004 – 78”
2005 – 78”
2006 – 78”
2007 – blank
2008 – Present 78”
I can find no Chatham longline survey setup info from those years (although I do see that surveys occurred!) I will keep digging.
There's some conflicting information in the 1997 ADFG Regional Information Report 1J97-26 (Cartwright and Carlile). For example, Table 2 suggests that hook spacing ranged from 78-84" in the 1997 Chatham LL survey.
