How and where is all of this stocking information communicated and organized?
The answer is a giant on-line Great Lakes Fish Stocking Database (Database) that is updated annually by Ryan Wehse of the Green Bay Fish and Wildlife Conservation Office (FWCO). Each stocking agency contributes stocking information for all species stocked in Great Lakes waters. The data is formatted into a standard database, and submitted to the Great Lakes Fishery Commission’s (GLFC) web designer Jeff McAuley by April 1st of the following year. The Database has stocking records dating back to the 1950’s and is available for the public to view at http://www.glfc.org/fishstocking/.
The Database allows fish managers, researchers, and the general public to determine the number of fish stocked by species, location and date for each of the five Great Lakes. The Database is an important data source for managers as it provides numbers of fish entering the population for stock assessment models, and provides others with the characteristics of stocked fish including fin-clip and coded-wire tag information. The Database plays an important role in supporting fisheries management decisions and informing users of historical and current fish stocking activities.
