The article highlights the challenges faced by caged fish farmers in BR-VT province, Vietnam, due to the Covid-19 pandemic. Approximately 400 tons of fish are unsold due to disrupted supply chains, low demand, and financial difficulties. The main issue is the inability of small-scale farmers, who lack the means to issue invoices and transport their produce, to sell to supermarkets. This problem is exacerbated by the high prices of fish, which are not feasible during economic downturns. Additionally, unsold fish that are too large or oversized due to overfeeding present environmental risks and are difficult to sell. The province, with over 500 cage fish farming establishments, is struggling to connect supply with demand and is experiencing challenges in farming and selling fish efficiently.
