The article highlights the significant rise in the cost of commercial cotton lobster and green lobster in Van Ninh district, Khanh Hoa province, with prices reaching over 2.1 million VND per kilogram. This has led to a surge in interest in lobster farming, although the limited supply of lobster seed is posing a challenge for farmers. The majority of lobster seed is imported from countries in South Asia, but the COVID-19 pandemic and environmental issues have impeded this supply. As a result, farmers are forced to buy lobster seeds at higher prices and wait for extended periods. In 2020, Khanh Hoa province saw over 1,500 tons of lobster output, but the industry is currently facing sustainability concerns due to environmental pollution, unstable production, and the lack of artificial reproduction of seed. The province aims to raise 52,700 lobster cages in 2021, a decrease from the previous year, due to these challenges.
