Artificial-induction upwelling marine ranch

Abstract

An artificial-induction upwelling marine ranching technology belongs to the technical field of marine fishery biological resources culture and proliferation. The artificial-induction upwelling marine ranching technology comprises building artificial fish reefs in shallow sea to providing breeding and foraging for marine organism, wherein the reefs with a certain slope can generate upwelling under the action of ocean currents of a certain velocity to improve the fishing yield. The artificial fish reefs are confined to water depth, ocean currents, terrains and substrate conditions and accordingly are high in investment cost. The artificial-induction upwelling marine ranching technology greatly breaks through the confine of the artificial fish reefs and can be implemented in shallow seas dozens of meters deep as well as in deep sea hundreds or thousands of meters deep to achieve artificial upwelling induction, and meanwhile, is low in investment cost. The artificial-induction upwelling marine ranching technology technically has the advantages of changing rigid materials into flexible materials, a three-dimensional mode into a planar mode and complexity into simplicity, avoiding confine of water depth, ocean currents, terrains and substrate conditions, being applicable to being implemented in ocean waters, achieving high economic benefits and significant social and ecological benefits and accordingly having an incomparably wide application range and great market economic value.

Description

technical field [0001] The artificially induced upwelling marine pasture technology belongs to the technical field of marine fishery biological resource augmentation breeding. Taking the surface of the deep ocean as the stage, carbon dioxide and water as raw materials, sunlight as the energy source, nitrogen, phosphorus, silicon, iron and other nutrients as the skeleton, and the marine ecosystem as the factory, to solve the problem of human food supply shortage as the driving force, artificially induced Upwelling is the basic technical approach to turn carbon dioxide, the culprit of climate warming, into a treasure. Large-scale production of plankton through photosynthesis of phytoplankton, enrichment and transformation of plankton with fish, shrimp, crab shells, and finally into fish meat, fish meal, fish oil, shrimp Crab shells and other food. Background technique [0002] The ocean area accounts for 71% of the earth's surface area, and the upwelling sea area, which accou...

Problems solved by technology

Variety improvement, increased per unit area yield, water conservancy construction, and the risky import of genetically modified food may temporarily alleviate the severe situation of food supply shortage, but they cannot fundamentally solve the problem of food crisis

Importing food from the international market can only make up for the urgent needs of the moment, and cannot be used as a guarantee for the daily life of such a large population in China
