The National Institute of Fisheries Science projected that this year, the sardine resources in the waters near our country would maintain a level similar to last year. According to the analysis results of the scientific survey conducted in the first half of this year based on the "fusion detection technology," the influx of spawning individuals decreased slightly compared to the previous year, but the density of egg masses and the total catch volume increased. The fusion detection technology is a survey method that comprehensively evaluates the spatial distribution and resource density of sardines by detecting fish schools with scientific fishing equipment, followed by continuous egg mass collection, environmental DNA analysis, and catch trial surveys. In this year's survey, the average acoustic density of fish schools (NASC) in the main distribution area of sardines, the southern coast, was measured.
