ACOUSTIC FISH RECONNAISSANCE

For a long time and until now, there has been a serious need for the work that would systematically present the whole subject of the acoustic fish reconnaissance and detailing all the most important and major technical aspects of the application of the acoustic equipment in the field of commercial fish reconnaissance, and also offering readers sufficiently deep and thorough analysis of the actual effectiveness of the established fish-finding techniques.

The publication by K. Yudanov and I. Kalikhman was specifically worked out and released to respond to this need through provision of the required comprehensive overview of both theoretical and practical aspects of the acoustic detection and search, as well as the interpretation and estimation of the population, performed for commercial benefit. Particular and close attention has been paid by the authors to the accounting surveys for the quantitative estimation of relevant bio-resources and fishing conditions in the areas considered traditional for fishing activities.

They have also analyzed different applications of the acoustic technique on the basis of the extensive investigations carried out by themselves. The main content of the volume includes the results of the applicability of the various fish-finding tools, and useful recommendations on the improvement of the techniques in question.
