The invention discloses a method for industrial aquaculture of gloiopeltis algae. The method includes setting up an aquaculture shed with a transparent shed top and arranging a plurality of rows of transparent aquaculture devices in the aquaculture shed; placing gloiopeltis alga fingerlings in the transparent aquaculture devices, adding seawater and performing aeration to enable the gloiopeltis alga fronds to present a suspension state; suspending the transparent aquaculture devices cultivated with the breeding fingerlings on a support for breeding in the aquaculture shed which is provided with the transparent shed top and set up outdoors; and taking out the fronds regularly and fracturing into the fingerlings for enlarging cultivation. The invention further discloses the aquaculture shed and the transparent aquaculture devices. According to the method, the shed and the devices, growth of the fronds is facilitated, the working efficiency is high, and the cost is low.
