Fisheries production hit 2.03 million tons in the January-June period, up from 1.82 million tons tallied for the previous year, the data released by Statistics Korea showed.
The latest findings showed fish caught in coastal waters moving up 14.3 per cent on-year, while those produced by aquaculture shot up 16.5 per cent, YonhapNewsAgency.
On the other hand, fish caught outside South Korea in international waters or those caught in exclusive economic zones of other countries backtracked 3.9 per cent.
The statistics office said that the total value of fish output stood at 3.34 trillion won ($2.8 billion) down 1 per cent from 3.37 trillion won for the first six months of 2014.
It attributed the dip to more inexpensive fish being caught in coastal waters and a sharp drop in expensive tuna and Antarctic krill being caught by South Korean fishing boats operating abroad.
