This study was conducted at the Boncong Bancar Marine Farming Facility in Tuban, East Java, focusing on Blue Swimming Crab (Portunus pelagicus) aquaculture. As a high-value seafood commodity with crucial export markets, the study aimed to enhance knowledge and skills, providing valuable insights for students and stakeholders. It emphasized the need for sustainable aquaculture to reduce reliance on wild harvesting, as Blue Swimming Crab demand exceeds natural supply. The research adopted a descriptive approach, including biological characteristics, survival rates, behavior, water quality, and feeding techniques according to MFF Boncong standards. Water quality measurements resulted in an average pH of 6 to 8, temperatures not exceeding 33°C, dissolved oxygen levels between 5.0 ppm and 8.4 ppm, and salinity between 30–35 ppt. In summary, Blue Swimming Crab aquaculture offers a profitable business opportunity, contributing to the country’s foreign exchange reserves, and warrants close attention from fisheries experts.
