This is a specific catch issue. Rather than adding to the long thread in #9, I'm adding as its own issue.
California rec data has a number of gaps that need decisions to fill.
Currently there are no 2004 data in RecFIN or MRFSS. The issue is for all species. Issue likely wont be resolved by RecFIN until off-cycle.
Solution Use a value of 10.59 mt, provided by @JohnBudrick via email on March 18, based on a past pull during the gopher rockfish assessment. The previous canary rockfish assessment appears to have used only landings data, not A + B1, so is why we dont use that value.
PC mode estimates are zero during the period 1990-1994, and negligible for 1995.
Solution No estimates are available for any mode 1990-1992. So for 1993-1995 I suggest 'estimating' PC values based on the ratio of PC to PR as opposed to any type of interpolation. I use an average ratio across all years, but omit 1995 because of the VERY low estimate for PC.
There are no estimates in 1990-1992 for any mode.
Solution Can do linear interpolation (blue dots below), or take averages (average 1987-1989 for 1990, 1987-1989 and 1993-1995 for 1991, and 1993-1995 for 1992; red line below). No one is right, so pick one and go with it. UPDATE: went with average in commit 6601c20
Estimate in 1980 from MRFSS is somewhat high. Redid same assumption from the 2015 assessment to average 1979 estimate from historical period with 1981 estimate from MRFSS.
