A hatchery for producing baby shrimp to be used as fish food in home aquariums. A water container has a removable cover with a central aperture from which an annular wall extends downwardly into the interior of the container, the bottom of the wall releasably supporting a two-part pick-up cup comprising a housing and therebelow a separable closure trap attached to a hand manipulable stem extending up through said housing, said annular wall and cover aperture. The assembly is placed under a light, and the closure trap permitted to drop to the base of the container, thereby leaving a space between the housing and the trap. Shrimp eggs that were placed in the partially filled container hatch, and the baby shrimp, attracted to the light seen through the bottom of the housing, swim toward the light, through said space and up into the housing, whereafter the stem is raised to lift the closure trap into engagement with the bottom of the housing, thereby trapping the shrimp. The two-part pick-up cup is then lifted out of the container and transferred to an aquarium, the shrimp being released, for use as fish food, by lowering the stem to separate the trap from the housing and dipping the separated trap into the aquarium water.
