The Ministry of Fisheries, in close ties with researchers of the Institute of Fishery, established a culture ground and succeeded in the artificial spawning of various kinds of flounder fries including stone flounder, brown sole, dab and plaice.

It also solved such problems as promoting the artificial maturity of spawners and boosting the survival rate of fries by ensuring early and assorted feeds with unicellular seaweeds, rotifers and brine shrimp.

Since last year, Ryonjin, Kim Chaek, Yanghwa, Riwon and Cholsan fishery stations have put over two million flounder fries into the sea.

It is the plan of the ministry to increase the number of fishery units and breed many more flounder fries.

According to Kim Yong Chol, vice-director of the ministry, it is striving to establish an artificially spawning technology of fleshy and high nutritive starry flounder.

Meanwhile, the ministry built bases for producing fries of Alaska pollack, salmon, swellfish, flatfish and rock fish and settled their artificial spawning problem to put millions of fries into the East and West seas of Korea.
