There is provided, in a preferred embodiment, a hydroponic apparatus for growing plants within a confined space. Plants rooted in removable containers are placed within a receptacle that rotates on a vertical axis. During hydroponic fertilization a recirculating system delivers and transfers the nutrient solution to and from the receptacle. The plant container in the preferred embodiment allows for removal, replacement, and repositioning of plants within the receptacle. The preferred method increases the photosynthetic service area of the light source in a confined space by arranging a plurality of hydroponic apparatus beneath the light source. The combination of removable containers and rotating receptacles with a plural arrangement of apparatuses prevents algae growth, empowers the grower with plant manageability, and amplifies plant productivity.

The invention discloses a rock worm-gracilaria-sea cucumber pond mixing breeding method. A stereoscopic mixing breeding can be implemented in the inshore breeding ponds by manually putting in sea cucumbers, rock worms and gracilaria seedlings. Breeding space and nutrient substance of the sea cucumber pond can be effectively utilized to be converted into gracilaria plant productivity, wherein the gracilaria plant productivity is provided with economic value. Pond eutrophication can be prevented from happening. Pond sedimentary organic particulate matters of sea cucumber excrements and the like can be effectively utilized as baits for rock worms. Polluting rate of pond bottom which is caused by excessive accumulation of sea cucumber excrements can be reduced. Then, breeding benefits of a pond unit can be improved. Because the rock worms are high in economic value, benefit rate of a yield per unit area of the mixing breeding can be enhanced for 1-2 times. The rock worms can be caught in one time through a labor excavating method every three years. Pond bottom dredging and substrate renovation can be implemented at the same time in the catching process. The difficulty that substrate sludge of common aquaculture ponds of a common pond can not be cleared for a long time can be overcome.
