The January haul of ayu sweetfish from Lake Biwako was a mere 3% of the average, marking the lowest catch since record-keeping began in 2009. This drastic decline is attributed to poor spawning conditions caused by the scorching heatwave experienced last summer.
The low catches have significantly impacted the industry, with fisheries cooperative associations unable to fulfill orders from ayu breeders and shipments to retailers and restaurants falling behind. The situation has caused financial hardship for fishermen, with some被迫暂停运营.
The Shiga prefectural government is closely monitoring the situation and working to understand the factors contributing to the decline in ayu catches. They are also exploring potential solutions to mitigate the impact on the industry and ensure the sustainability of ayu populations in Lake Biwako.
