    Abstract

    Acoustic surveys are the most powerful tool of krill abundance estimation and distribution mapping. The International Community needs to prepare standard requirements and procedures for acoustic instrumentations to be used, as well as for survey design, data acquisition, processing, storing and analysis. In the paper possibilities and approaches to preparation of recommendations for acoustic surveys of different scales (macro, meso, micro) are reviewed. It’s concluded that the most items of the recommendations and standard procedures could be prepared and agreed basing on existing experiences and approaches to survey design and data analysis. The paper could be considered as a base for critical discussions of the recommendations to be prepared by international group of specialists.
