Fishermen in Vietnam's Dien Chau district are experiencing low profits due to falling prices for jellyfish and herring, despite the current season being one of the most productive. Jellyfish prices have halved to 600-700 VND per kilogram, and herring prices have dropped to 8,000 VND per kilogram, a quarter of the previous year's price. This is attributed to the COVID-19 pandemic, which has disrupted export markets and reduced domestic demand.
