PREFACE
Late in 1999 project staff determined that computer programs used to process data from this study and
produce estimates for 1995 through 1997 contained errors. These errors altered some angler’s
reported catch and harvest. The errors did not affect all species or fishing locations in the same way;
thus some estimates were too high, while others were too low. In addition, when generating estimates
for angler-days fished and household trips the computer programs did not properly account for anglers
who did not respond to the survey. This error resulted in estimated days-fished and household trips that
were too high for 1995 through 1997.
The division’s technical staff also determined during review of the effect of the above errors that the
approach used to account for anglers who did not respond should also be adjusted to reflect the
approach published in current scientific literature. This adjustment would affect some 1995-1997
estimates and some 1998 estimates.
The 1996 through 1998 estimates have been revised. We are unable to retrieve the raw 1995 data due
to a faulty data tape and thus those estimates cannot be adjusted. Statewide and regional comparisons
of original and revised estimates are included in the Discussion section of this report. The recomputed
1996 through 1998 estimates are also included in summary tables in this report. The more detailed
recomputed estimates will be published in revised editions of Fishery Data Series Nos. 99-41, 98-25,
and 97-29. Summaries of sport fish survey results, including revised 1996 through 1998 estimates, are
available on the Internet at:
http://www.sf.adfg.state.ak.us/statewide/participationandharvest/html/index.cfm
The division has a commitment to producing the best information possible for making make management
decisions about Alaska’s recreational fisheries and we strive to improve our studies each year. We
regret that these errors occurred, have taken steps to avoid such problems in the future, and have
committed resources to correct estimates where possible.
In light of the above, anyone who has used 1996 through 1998 estimates from the Statewide Harvest
Survey project may wish to review the changes that have resulted from these recalculations.
The purpose of this report is to provide the revised 1996 estimates. The data processing, and
estimation procedures used to produce revised 1996 through 1998 estimates are described in Howe, et
al (2001).
