The article highlights the significant impact of the Covid-19 pandemic on the grouper fishing industry in Cam Thinh Dong commune, Cam Ranh city. The pandemic has disrupted both export and domestic markets, resulting in a drastic drop in grouper prices from 150,000 - 170,000 VND per kilogram to 90,000 - 110,000 VND per kilogram, a nearly 50% decrease. This has led to substantial losses for farmers, with some facing difficulties in selling their stock and experiencing financial challenges. The situation is particularly dire for those with large stocks, as the slow domestic market and limited purchases by traders exacerbate the problem.
