Аннотация:
В работе представлены результаты эхометрических исследований трёх экспедиций ВНИРО в атлантический сектор Антарктики. Объект исследований - миктофиды. Гидроакустические работы в этих экспедициях включали: проведение эхометрических съёмок, изучение поведения скоплений, определение степени наполнения трала и промысловой значимости при облове скоплений миктофид./The article presents data of acoustic surveys from three cruises of VNIRO to the Antarctic Atlantic Sector. Lanternfish were the object of research. Hydroacoustic investigations in these cruises included assessment surveys, behaviour studies, estimates of the accumulation of the catch in the trawl and the evaluation of commercial importance of exploited lanternfish concentrations. Biomass assessments for surveyed areas in different seasons are given. It is noted that summer and summer-autumn periods favour acoustic surveys, while summer is more preferable for fishing operations. The method is suggested for the evaluation of commercial importance of concentrations and control of the catch accumulation in the trawl during fishing operations using echo integration through relevant regression equations.
