Humpback Stock Proportions

Curtis et al. (2025) estimated humpback whale stock proportions for latitude bins along the U.S. West Coast. The R package ApportionMnStocks (Curtis, 2025), available on GitHub and forked to the SWFSC GHE organization, allows users to estimate stock proportions for a latitude (range) of interest based on these results.

• Additional data and files:
  • R code for this analysis is in the Mn-StockProportions-USWC-2025 GitHub repository that has been forked to the SWFSC GitHub Enterprise organization.
  • The version of the CRC MN ID database used for this analysis, is available at ‘SWFSC-MMTD-CMAP://Alex Curtis/Humpbacks/data/MN ID 20250303.zip/MN ID.mdb’.
