The Ministry of Oceans and Fisheries has reported a 10% increase in deep-sea fisheries production in 2019, with the total output reaching 510,000 tons. However, the number of seafarers and the profit margins of seashore companies have decreased, leading to challenges in the marine industry. The majority of the catch was bonito, accounting for over half of the total production. Despite this, the number of domestic deep-sea companies and fishing vessels have decreased, while the number of workers has increased, leading to a crew shortage. Furthermore, the average assets of ocean companies have increased but so has their debt, along with a decline in profit margins.
