-Outstanding issues for WA:
+#### Outstanding issues for WA:
1. There are three values for `RECFIN_WATER_AREA_NAME`: Estuary, Ocean, and Canada. Which should be included? Above table excludes Canada.
2. 2023 has a number of instances where `RECFIN_WEEK` is zero, and one instance where is it missing. In the instance where it is missing, there is no estimate of catch in mt.
3. Will likely convert the numbers in the historical sport landings to weight in mt. On the to do list.
-Outstanding issues for CA:
+#### Method for CA MRFSS catches:
-1. 2020 and 2021 proxy catches and un-ID'ed rockfish apportionment are missing.
-2. MRFSS data (1981-2004) does not have an obvious way to determine whether catches should be assigned to the northern or southern stock.
+From Albin et al. (1993), which covers 1981-1986, calculate two ratios:
+1. Total catch in Del Norte/Humboldt / total catch in all counties
+2. Total catch in Del Norte/Humboldt / total catch in all counties except SLO
+
+From CRFS data for 2005-2010, calculate total catch in Redwoods district / total catch in N. CA sub-region
+
+From MRFSS data, calculate total catch by year in N. CA sub-region
+
+For CA rec catch estimates for the assessment:
+
+- 1980-1989: Multiply total N. CA catch by Albin ratio (2)
+- 1993-2004: Multiply total N. CA catch by weighted average of Albin ratio (1) and CRFS ratio. Weights are inverse of time to last Albin year or first CRFS year.
+- 1990-1992: Interpolate between average of 1987-1989 and 1993-1995
+
+**Concern**: Catches for 1980-1989 look somewhat high. They exceed rec catches in OR in 1982 and 1983.

+1. Exclude released fish from comps
+2. Lump released and retained fish together
+3. Model a retention curve
The fish in Washington also look slightly larger than those in Oregon and California. This difference is more pronounced than it is in survey data, indicating a possible selectivity effect.
I am unsure how to filter MRFSS data to measured lengths for WA and CA. The counts in the table above filters lengths to whole numbers (mm).
