内容简介：
William Carmichael McIntosh (1838-1931) was a Scottish physician and marine biologist and the first director of the Gatty Marine Laboratory, founded during 1896 in St Andrews. Originally published in 1921, this is the second edition of a work first published in 1899. The text is based on observations made, over a number of years, during trawling investigations off the coast of Scotland. In a lengthy and rigorous exposition, McIntosh argues that the restrictions imposed on trawling in coastal waters by the Fishery Board are unjustified, lacking a foundation in scientific data. This book will be of value to anyone with an interest in marine biology and fisheries policy.
