Annual abundance of adult alewives was indexed in most years using 1.5 and 2” mesh gillnets.
	The catch rate rose from 1990 to 1994, remained relatively high to 1995, but had declined to below the 1990 level by 1998.
	This trend in alewife abundance parallels annual harvest of brown trout in Thunder Bay, with peak in harvest from 1993-1995, following years of high alewife catch rates.
