| 摘要 |
A crustacean larva raising method includes the steps of providing a tank (50) to hold larva raising medium, continuously supplying sterilized, filtered larva raising medium to the tank (50) through outlets (64) adapted to cause horizontal circulation of the medium and at an outlet flow velocity preventing larva damage, continuously draining the medium through a drain assembly (65) including a larva screen and maintaining the medium at a selected temperature. Apparatus to carry out the crustacean larva raising method comprises of modular channel sections (51, 52) of the tank (50), which are bolted and sealed together, two sub tanks (53, 54), a UV sterilizer unit (55) incorporating temperature control means and a submersible pump (56) to circulate filtered and pre-sterilized medium. A crustacean larva feeding composition and a method for preparing such a composition are also provided. |
