Aggiungi al carrelloPaperback. Condizione: New. Print on Demand. This book delves into the results of a three-year study on the feasibility of commercial bottom trawling in Green Bay, Lake Michigan. The author presents findings from 179 exploratory trawl drags conducted over 11 cruises between 1963 and 1965. The study examined various depths and seasons to determine the abundance and distribution of fish species. The results indicate that bottom trawling in Green Bay could be commercially viable, with alewife and smelt being the most abundant species. The study provides valuable insights into the potential of bottom trawling as a sustainable fishing method in the Great Lakes region. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Aggiungi al carrelloPaperback. Condizione: New. Print on Demand. This book explores the commercial fishing industry of Lake Superior from the mid-1950s to the mid-1960s. During this time, there was a decline in lake trout and whitefish populations which forced fishermen to explore other methods to continue supporting a profitable fishing industry. The author provides a detailed account of six fishing cruises as well as information on the gear and methods that were used during the ten-year period. Analysis of the catches reveals that a limited commercial trawl fishery could be supported and provides insight into the impact of fishing on lake trout populations.
