This creation system is a kind of built-in automatic hatching feeder, hatches shrimps using what, includes: a circular tube shaped ontology, a upper cover and a lower cover. Circular tube shaped this system is made of lighttight material, over and under is respectively provided with an opening, and internal with an accommodating space, is equipped with a transparent block close at lower section on front side of circular tube shaped ontology, and transparent block is equipped with an elongated perforation, and is equipped with an impermeable baffle plate in the Hou side of transparent block. Upper cover system covers the opening above circular tube shaped ontology, and upper lid is equipped with a gas vent. Lower cover system is fixed on the opening of circular tube shaped ontology lower section. Thereby, shrimps can be hatched automatically and easily, while shrimps naupiar larva, chorion, dead ovum can be automatically separated again, to avoid fry have chorion, dead ovum and cause death.本創作係為一種內置式自動孵化餵食器,應用於孵化豐年蝦,包含:一圓管狀本體、一上蓋以及一下蓋。圓管狀本體係為不透光的材質所構成,上方及下方各設有一開口,且內部具有一容置空間,在圓管狀本體前側接近下方處設有一透明區塊,且透明區塊上設有一長形穿孔,並在透明區塊的後方設有一不透光擋板。上蓋係罩覆在圓管狀本體上方之開口處,且上蓋上設有一排氣孔。下蓋係固定在圓管狀本體下方之開口處。藉此,能夠自動且便利的孵化豐年蝦,同時又能自動分離豐年蝦無節幼蟲、卵殼、死卵,以避免魚苗吃到卵殼、死卵而造成死亡。
