By turning to more advanced aquaculture fisheries, the Ministry of Maritime Affairs and Fisheries (MOMAF) plans to encourage the industry to reduce production costs so that it can compete favourably with its foreign counterparts. Between the period of 1997 and 2003, aquaculture production of aquatic plants dropped by 30% and mussels by 75% [14]. On the other hand, demersal fish such as olive flounder and black rockfish increased by 78% [14]. There has equally been an increased interest in farming of shrimps (P. chinensis and P. japonicus) and the mitten-handed crabs, previously only cultured in China. As a result, crustacean production has increased by 48% between 1997 and 2003. There has been a great increase in production of high value fish species, such as olive flounder and black rockfish during the last few years and a new interest in culturing penaeid shrimps. The vision of South Korea is a restructured aquaculture industry with an optimal production system and enhanced competitiveness. While doing this, Korea will be reducing by 10% production facilities devoted to high volume products such as laver and sea-mustard with no new licences to be issued during the next five years. Total funds invested were US $14.9  There is a growing concern that pollution might affect fishing and aquaculture production due to the reclamation works and construction of industrial complexes in the southern and western coastal districts of the country. Recently, the integrated aquaculture management has created an alternate plan to overcome problems such as red tide, typhoon and pollution created by human activities. In this plan, the scope of ‘aquaculture ground’ extends to open areas. It is divided into three subdivisions; land-based aquaculture, polytrophic aquaculture, and offshore aquaculture, all of which are relatively new concepts in the Korean aquaculture industry.
