Living resources of the sea and fresh water have long been an important source of food and economic activity. With fish stocks continuing to be over-exploited, there is a clear focus on fisheries management, to which acoustic methods can and do make an important contribution.

The second edition of this widely used book covers the many technological developments which have occurred since the first edition; highly sophisticated sonar and computer processing equipment offer great new opportunities and Fisheries Acoustic, 2e provides the reader with a better understanding of how to interpret acoustic observations and put them to practical use.

Well known and respected authors Emphasis on practical acoustic methods Detailed coverage of a commercially and environmentally important subject

A vital tool for fisheries scientists, fisheries oceanographers, environmental biologists, ecologists, population biologists, fish biologists, and marine biologists. All those involved with design and use of acoustic equipment. Libraries in research establishments, government stations and universities where fisheries science is studied or taught will find this a welcome addition to their shelves.

Everything you will read in these pages happened. Some of the names have been changed a little to preserve anonymity but hey, we all need to keep some things secret! When we meet characters in our life who don’t conform to the norm or find ourselves in situations that take us out of our comfort zone, we should rejoice, because it is these people and these scenarios that colour our souls with the vivid shades. We realise that life is a ride where sometimes it’s easy and sometimes your metaphorical brakes fail at spectacularly inopportune moments. As I trawled through my memories of the last half-century, I picked out those moments where a particular emotion was running high, be that joy or anger or frustration. These eleven chapters tell you about such times and - guess what - describe when the brakes have failed, and, not only that, but the wheels had fallen off as well.
