### Objective
## 1. Calculated slot yield (n) by weight
## 2. Calculate bag specific slot reductions
#### 2.b.new, bag reductions are not length specific, bag > 4 were converted to 4 fish bags, which increased the number of 4 fish bags...
## 3. Selectivity as calculated by catch/population structure asap
## 4. Include dead discards
## 5. Explore all slot options inclusive of min size, below max size
## 6. Include rec harvest scaling for non compliant
## 7. Recrational and commercial harvest
### Options:
## cur.catch
## a. Is this for commercial or rec only?
## b. Seasonal changes? They need to be inpusted here.
## c. Are discards included?
## d. Growth information
##"C:\Users\jacob\OneDrive\UCONN\Projects\Tautog_ASMFC\eric data analysis\February 2017\total fecundity estimate new2.xls"
## e. length data is based on 2012-2015
## f. age data (for selex) is based on 2012-2015
####ASK ERIC
## g. why? because ASAP popN has fish aged to 26, but if I restrict ages to fish
## measured in 2012:2015 then max age is 17
## h. smoothing function for selectivity, used 3 year average, for all ages,
## repeated age 2 and age max-1 for age 1 and age max
### Inputs
## New_MRIP_Bag.r (MRIP_read_data.r)
## LIS Age-Length raw data read.csv("C:/Users/jacob/OneDrive/UCONN/Projects/Tautog_ASMFC/Amendment1/database/LIS_Tog_AL_data.csv
## Population age structure from ASAP (mean over last selex block)
