Seaweed mariculture is accepted to have begun during the Tokugawa (or Edo) Era (AD 1600–1868) in Japan. Mariculture of any species creates when society's requests surpass what normal assets can supply. As request builds, regular populaces habitually become overexploited and the requirement for the development of the suitable species arises. As of now, 92% of the world kelp supply comes from developed species. Contingent upon the chose species, their science, life history, level of tissue specialization, and the financial circumstance of the district where it is created, development innovation can be low-tech (and still incredibly effective with profoundly productive and basic culture methods, combined with escalated work at low expenses) or can turn out to be exceptionally cutting-edge and automated, needing ashore development frameworks for cultivating a few periods of the existence history before development out at vast ocean hydroponics locales. Development and seed-stock improvement procedures have been refined over hundreds of years, generally in Asia, and would now be able to be profoundly modern. Super advanced ashore development frameworks have been created in a couple of uncommon cases, generally in the Western World; business practicality has possibly been arrived at when high worth added items have been acquired, their business sectors got (not really because of a neighbourhood interest, but rather frequently for commodity to Asia), and work costs diminished to adjust the huge innovative speculations and functional expenses.

Since the mariculture of sea-going plants (11.3 million tons of kelp and 2.6 million tons of undefined 'sea-going plants' accounted for by the Food and Agriculture Organization of the United Nations) has grown basically in Asia, it remains generally obscure in the Western World, and is regularly disregarded or overlooked in world measurements … a circumstance we can just disclose as being because of a well-established zoological predisposition in marine scholastics, asset directors, administrators, and strategy consultants! Be that as it may, the kelp hydroponics area addresses 45.9% of the biomass and 24.2% of the worth of the world mariculture creation, assessed in 2004 at 30.2 million tons, and worth US$28.1 billion. Mollusk hydroponics comes next at 43.0%, and the finfish hydroponics, the subject of many discussions, in reality just addresses 8.9% of the world mariculture creation.

The seaweed hydroponics creation, which nearly multiplied somewhere in the range of 1996 and 2004, is assessed at 11.3 million tons, with 99.7% of the biomass being developed in Asia. Earthy colored kelp addresses 63.8% of the creation, while red seaweed addresses 36.0%, and the green seaweed 0.2%. The kelp hydroponics creation is esteemed at US$5.7 billion (again with 99.7% of the worth being given by Asian nations). Earthy colored kelp rule with 66.8% of the worth, while red seaweed contribute 33.0% and the green seaweed 0.2%. Roughly 220 types of kelp are developed around the world; be that as it may, six genera (Laminaria (kombu; 40.1%), Undaria (wakame; 22.3%), Porphyra (nori; 12.4%), Eucheuma/Kappaphycus (11.6%), and Gracilaria (8.4%)) give 94.8% of the seaweed hydroponics creation (Table 4), and four genera (Laminaria (47.9%), Porphyra (23.3%), Undaria (17.7%), and Gracilaria (6.7%)) give 95.6% of its worth. Distributed world measurements, which routinely notice 'information bar sea-going plants' in their tables, demonstrate that in 2004 the main ten individual species created by the worldwide hydroponics (50.9% mariculture, 43.4% freshwater hydroponics, and 5.7% brackishwater hydroponics) were Pacific measured shellfish (Crassostrea gigas – 4.4 million tons), trailed by three types of carp – the silver carp (Hypophthalmichthys molitrix – 4.0 million tons), the grass carp (Ctenopharyngodon idellus – 3.9 million tons), and the normal carp (Cyprinus carpio – 3.4 million tons). Be that as it may, indeed, the kelp, Laminaria japonica, was the main top species, with a creation of 4.5 million tons
