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.

Book Description
Drawing on a number of case studies from around the world, this publication considers how the local knowledge and practices of indigenous fishing communities are being used in collaboration with scientists, government managers and non-governmental organisations to establish effective frameworks for sustainable fisheries science and management. It seeks to contribute towards achieving the goal of establishing international responsibility for the ethical collection, preservation, dissemination and application of fishers' knowledge.
