Value
data frame summarizing the TAMM limiting stock tab. The "block" of the limiting tab is identified with column "stock_type". "first_section" is the first section in the TAMM; this section is primarily natural fish but includes some hatchery fish if they were included in management objectives. "ALL_H" is all hatchery fish (in TAMM, block starts on row 81), "UM_H" is unmarked hatchery (in TAMM, starts on row 160), "UM_N" is unmarked naturals (in TAMM, starts row 239), "AD_H" is marked hatchery (in TAMM, starts row 318), and "AD_N" is marked naturals (unless programs begin marking natural fish, this should always be all 0s; in TAMM starts row 397).
