Development of loco seed production at North of Chile
Development of loco seed production at North of Chile Masatoshi FUTAGAWA September 19, 2016 Our project, between UNAP and regional government of Tarapaca chile, develop mas seed production method of loco ( Concholepas concholepas ) in order to recover loco natural resources from 2013 to 2015. We completed the method that broodstock rearing, maturation and capsule incubation. Hatch-out larvae are produced all year round constantly and over 200 million of hatch-out larvae are released to our coast. Also we produced some larvae which grew more than 130 days after hatch-out with clear water which filtered, disinfect ed by UV and sterilized with autoclave . However, we couldn’t develop mass seed production method. The mass seed production technology is under studying by decades and aim is not accomplish yet in Chile . Because of the following reasons make hard to achieve. Loco larvae has four month planktonic period (veliger stage) that very long period c...
