What data is collected?
The data collected includes lake fished, date fished, port or area of origin, grid where a majority of the fishing occurred on that excursion, hours fished (dock to dock), total number of anglers, catch (number harvested and number released) of major species, fish specie(s) targeted, and number of sea lamprey seen attached to Chinook salmon and lake trout. Space is also provided on the report form for comments and observations. Completed data forms are returned to the Charlevoix Fisheries Research Station where they are logged, coded by port, and entered on computer.
How is the data used?
Three measures of fishing effort are summarized: angler hours, angler trips, and charter excursions. Angler hours are based upon total hours fished (dock to dock) by each angler. An angler trip is one completed fishing outing by one individual. A charter excursion is one completed boat trip. For example, if a charter operator took four anglers fishing for 6 hours, total fishing effort would be 24 angler hours, 4 angler trips, and 1 charter excursion. Charter data are also used to summarize the harvest, catch, harvest rate, and catch rate of fish listed on the form. Summaries of catch and effort for selected ports around the Great Lakes, totals for each lake, and annual reports are prepared each year.
