Book Description
Excerpt from Bottom Trawl Explorations in Southern Lake Michigan, 1962-65 The alewife stocks have increased tremendously in recent years. The poundage of alewives in the trawl catch increased each year from 17 percent in 1962 to 74 percent in 1965. Alewives exhibited pronounced seasonal movements and generally were available to bottom trawls only at Specific depths. The trawls caught alewives at depths of less than 5 fathoms to over 50 fathoms. Alewives appeared to be distributed universally in the study area during most of the year but were found only in some sections in winter. Alewives were more difficult to catch between July and the end of December than during January through June.

Book Description
Excerpt from Bottom Trawl Explorations in Green Bay of Lake Michigan, 1963-65 Figure 2.-availability of alewives to bottom trawls in Green Bay by depth and month April December. Figures illustrate the catch rate of alewives at 5-fathom depth intervals. Alewives were lacking in all drags in April, and catches were light in May. By June, ale wives were spawning, and the catch rate was highest at 5 fathoms and declined sharply below 15 fathoms. The best catch rate in July was obtained at 10 fathoms. During August, fish could be taken at all depths, but the largest concentrations were at 15 fathoms. In October and November, alewives were scattered at all depths, and large concentrations on the bottom were difficult to find. During December, most alewives were in the deeper waters of the bay few were found in shallower depths. Alewives apparently move out of Green Bay into deep water in Lake Michigan in January and do not return until May. Commercially significant catche s (500 pounds or more per half hour) were made on every cruise from June through December.
