Abstract
A deep water drawing step of drawing deep water that exists in a deep region of the sea to a surface region of the sea with an upwelling pipe (1); and a phytoplankton culturing step of culturing the phytoplankton in the upwelling pipe (1) are included to produce, as a basic producer of a food chain, a living marine resource, such as fishes and shellfishes, with phytoplankton produced in the phytoplankton culturing step.
Claims12
A living marine resource production method in which a living marine resource is produced with phytoplankton as a basic producer of a food chain, the living marine resource production method comprising:
- drawing deep water that exists in a deep region of the sea to a surface region of the sea with an upwelling pipe formed by a light-transmitting pipe and a non-light-transmitting pipe;
- guiding light to the upwelling pipe through a light guide body and a lens, the light guide body having an inverted pyramid shape and a hole with a diameter equal to a diameter of the light-transmitting pipe;
- and
- culturing the phytoplankton in the upwelling pipe,
- wherein an outer wall of the light-transmitting pipe is coplanar with an outer wall of the non-light transmitting pipe, and
- wherein, in the phytoplankton culturing, when sunlight is irradiated to an upper end surface of the light-transmitting pipe, the irradiated sunlight is guided toward a lower end surface of the light-transmitting pipe, and around a circumference of the light-transmitting pipe.
A living marine resource production method comprising:
- drawing deep water from a deep region of the sea to a surface region of the sea with a light-transmitting upwelling pipe that has a light-transmitting property, the light-transmitting upwelling pipe formed by a light transmitting pipe and non-light transmitting pipe;
- guiding light to the light-transmitting upwelling pipe through a light guide body and a lens, the light guide body having an inverted pyramid shape and a hole with a diameter equal to a diameter of the light-transmitting upwelling pipe;
- and
- culturing phytoplankton in the light-transmitting upwelling pipe by sunlight that is received into an upper end surface of the light-transmitting upwelling pipe, and guided toward a lower end surface of the light-transmitting upwelling pipe, and around a circumference of the light-transmitting upwelling pipe.
