Mussel larvae production for Pacific beakfish larvae ( Oplegnathus insignis ) Masatoshi F UTAGAWA * ¹ Septiembre 17, 2012 *¹ Corporación Privada para el Desarrollo de la Universidad Arturo Prat, CORDUNAP, Iquique, Chile Mussel larva shows 50 m m approximately and swims freely. The size is ideal for primary live feeds for O. insignis larva. Mussel larvae are fed at density 50 larvae/ml with 6 hours interval from Day 3 to 10. Additionally, the larva has advantages of well nutrition and easy production. This method produces 30 million mussel larvae from a female at 30 hours after fertilization. The larvae survive until D2 and eggs settle on larva tank within 6 hours approximately. 1.    Mussel gonad shows that male has cream color and female has coffee color. 2.    Insert knife below the hinge, cut ligament and open shells. Press male gonad to release sperm and keep in bucket (A) with 10 L of ...

The value of Chilean fishes in Japan market Masatoshi FUTAGAWA / CORDUNAP May 1, 2012 Market price is one of the most important factors to select culture species.  Starting from the price, establish business model which combine marketing and technology. For example, distance to market (transporting time and cost), size of market (maximum production volume which maintain market price) and potential of market expansion, products forms (live, fresh, frozen, boiled or dry), buyers (wholesalers, supermarket, restaurant or direct to individual consumer). Production location and methods are selected according to market price to take maximum profits. For example, seed production method (intensive, semi-intensive or extensive), culture methods (cage, tank or releasing) and feeds kinds (fresh, moist pellet or dry pellet). Growth speed is the very important which minimize risk and cash flow cycle during the operation.  Japan market is one of the biggest market in the world ...
