Chile: EcoSea Farming’s confinement system scored a new milestone: after the climatic emergency in the Asian country, the fish were kept “in optimal conditions, without mortality or stress”.

Some good news recently came from Chilean-made technology for submersible cage rafts, developed by EcoSea Farming for growing Buri, a type of Seriola, in Japan.

The CEO of the company, Nicolás Castillo, tells Salmonexpert that during last September, the south of Japan -where EcoSea Farming has clients operating- suffered the passage of typhoons Maysak and Haishen, “where the last one was classified by the Japanese Association of Meteorology as “Very Strong”, with wind speeds of 157 to 192 km/hr, and whose eye passed over the prefectures of Kumamoto and Nagasaki, causing torrential rains and multiple landslides, which led to the evacuation of 8 million inhabitants in the region ”.

“Currently, EcoSea Farming has customers using its confinement systems with submersible technology for Buri farming on Azuchi-Oshima Island, Nagasaki Prefecture, a site that received winds of up to 90 Km/hr and waves that reached 10 meters high, those who used the qualities of technology for the first time, which successfully withstood these inclement weather”, highlights the executive.

Prior to the passage of the typhoons, indicates Castillo, the producers, with the support of the EcoSea Farming technical team, “performed the submersion maneuvers reaching a depth of 14 meters, and keeping the fish submerged for 3 days during each event. Once the climatic emergency was over, they returned to the surface, where it was confirmed that the fish were in optimal conditions, without mortality and without signs of stress (with completely normal feeding behavior), in addition to corroborating the structural integrity of the system”.

Meanwhile, the CEO of EcoSea Farming pointed out that the company “developed and validated submersible technology off the coast of Chile under different energy conditions, including tidal waves and tsunamis, and today it is working through its office and team in Japan, in supporting the development of local aquaculture, both with producers and with the Government, allowing safe and sustainable production 365 days a year”.

Thus, Castillo assured that “it has been shown that the technology of submersible cage rafts that we make in Chile is capable of installing crops in any part of the world, in different conditions, however inclement they may be. The truth is a great sign for us, as a country, to remain in the global aquaculture leadership”.
