31 Gray Seal Bycatch
Page Edit 1
Change the "Data Sources" section to read as follows:
Reported gray seal bycatch estimates and potential biological removal levels can be found in publicly available documents, namely NOAA Fisheries Northeast Fisheries Science Center (NEFSC) Center Reference Documents (CRDs) on the NEFSC publications page and Marine Mammal Protection Stock Assessments respectively. More detailed documentation as to the methods employed can be found in the CRDs.
Page Edit 2 (if applicable)
change the first paragraph in the "Data analysis" section to read as follows:
Annual estimates from all fisheries as reported in the CRDs are summed together and the CV of the sum is calculated using the delta method. The 95% confidence intervals are then calculated from the sums and associated CVs, assuming a lognormal distribution.
LCI = estimate / exp[qnorm(0.975) * sqrt(log(1+CV2))]
UCI = estimate * exp[qnorm(0.975) * sqrt(log(1+CV2))]
