The fishermen of the Chongjin Fishery Station increased the per-net and per-boat production through timely monitoring of movement of shoals of fishes and intensive and continuous net-casting casting.

The Sinam Fishery Station has introduced an advanced support system of detecting fishing grounds and dispatched fishing boats to the main fishing grounds to increase the fishing output with rational fishing methods.

Kim Chaek and Ryongjin fishery stations, too, are catching a large amount of fish through a socialist emulation among units and mobile fishing campaign.

Meanwhile, fishery stations with modern processing facilities are processing and storing fishes as soon as they are caught.
