The National Institute of Fisheries Science has predicted that the West Sea fall crab catch will be between 88-114% of the average, with a total of 10,225.5 tons at most. This is lower than last year's catch, which was the highest in the past 10 years. The institute makes these predictions twice a year to support safe fishing and stable income for crab fishermen. The fall fishing season is expected to see a decrease in fishing efficiency due to several factors, including the weakening of the cold water in the Yellow Sea bottom layer during the summer. A survey conducted during the closed fishing season showed a variety of crab types, with different catch rates depending on the location and time of year. The director of the fisheries department stressed the need for continued research and monitoring to ensure a sustainable fisheries industry, as crab resources can fluctuate sensitive to changes in the marine environment.
