The Status of Kelp Exploitation and Marine Agronomy, with Emphasis on Macrocystis pyrifera, in Chile

摘要: Kelp cultivation started in Japan, China and Korea, mainly for human consumption; new applications are still expanding. In Chile, three ‘wild’ Lessonia species Macrocystis pyrifera under a strong increasing pressure of exploitation alginate production as source feed abalone. Regulatory restrictions kelp the increased demand biomass provided positive environment installation farming industry. Pilot-production studies demonstrated that 200 tonnes (fresh)/ha/year can be achieved genetic diversity breeding suggested this volume could increased. disease research is necessary condition securing future development industry, environmental on impacts large-scale aquaculture. Beyond bioremediation, ecosystem service effects provide, especially region such southern where intensive salmon mussel occurs. Life Cycle Assessment suggests energy returns investment positive, but more detailed data required.
