The Ministry of Oceans and Fisheries in South Korea is implementing a prohibition period for the catching of five fish species, including snow crab, blue crab, octopus, red skate, and pearl chicken shrimp, to protect aquatic resources. The prohibition includes certain periods for male snow crabs, blue crabs, and octopus, as well as a ban on catching fish under a certain length. The ministry urges fishermen to adhere to these regulations to ensure the future abundance of these species.
