Результаты испытаний нового отечественного научного эхолота с расщепленным лучом, предназначенного для ресурсных исследований на внутренних водоёмах

Design of Russian scientific echo-sounder for resource researches is actual, especially after imposition of sanctions against the Russian Federation by the western countries, when sale of different foreign high- tech products was prohibited in Russia. Besides buying foreign equipment which is allowed for sale in the Russian Federation, our users don’t have opportunity to contact with the western partners as well as don’t have possibilities to modernize and improve purchased equipment. This article presents short technical characteristics of new russian small-sized echo-sounder model, named MIEL. For testing of new echo- sounder there was carried out hydroacoustic survey, also using scientific Simrad EY500 echo-sounder on Vazuza basin in autumn 2018. The EY500 echo-sounder was chosen as reference standard device as many years it was used by many Russian and foreign scientific organizations for resource researches on inland water. Fish school and single fish which were registered by EY500 and MIEL echo-sounder were completely identical. Completeness and convenience of information provided on the MIEL screen was significantly higher than the information, presented by EY500 echo-sounder. Also it should be noted the high extent of results coincidence of echo-counting and fish TS. Estimated lower cost of new Russian echo-sounder as well as its high technical characteristics which are well-compared with foreign analogues, and in some parameters surpassing them, compactness, makes this model more available and attractive for solution of fisheries and environmental problems.
