According to Pak In Gon, department head at the Ministry of Fisheries, fishery stations across the country stocked the sea with 10-odd species of artificially-bred non-migratory fishes like Alaska pollack, flatfish, rock fish, swellfish and croaker in recent years.

The Ryonjin Fishery Station and other fishery stations have bred millions of fries of Alaska pollack for the last three years.

The Kimchaek Fishery Station set a water zone for flatfish protection at an appropriate area and stocked it with many fries of flatfish for the last two years.

Meanwhile, the Jonjin Taebong Fishery Station remodeled culture farms favorably to breeding flatfish, thus opening a prospect to raise one hundred thousands of brown sole and dab each. And the Riwon Fishery Station recently stocked the sea with more than one million fries of flatfish.

Nampho Taegyong and Rakwon fishery stations have pushed ahead with the breeding of swellfish and the Hongwon Fishery Station and other fishery stations with breeding of rock fish and flounder.

A fishery station in Nampho City is breeding croaker.
