goa_rebs_catch_1977_2004.RdA dataset containing trawl and longline gear catch by year for 1977-2004
goa_rebs_catch_1977_2004A data frame with 28 observations and 2 variables:
year of catch
weight of catch in t
The catches from 1977-1992 were from Soh (1998), which reconstructs the catch history using an information weighting factor (λ) to combine catch histories from both survey and fishery information. The catches from 1993-2004 were constructed used observer catch data from the FMA Observer Program (Clausen et al. 2004, Appendix A). Observed catches were available from the FMA database by area, gear, and species for hauls sampled by observers. This information was used to calculate proportions of RE/BS catch by gear type. These proportions were then applied to the combined shortraker/rougheye catch from the NMFS Alaska Regional Office to yield estimates of total catch for RE/BS rockfish.
