A method of increasing yield of cultivated algae, which entails the step of cultivating one or more species of algae in the presence of one or more species of PPFM bacteria, for at least a portion of the algae cultivation.

The invention belongs to a low-carbon energy-saving method for treating polluted water quality of a lake or a landscape lake, comprising an aeration type aerobic device, floating landscape aerobic devices, aquatic floating plants and cultured fishes, wherein the aeration type aerobic device is positioned in a water inlet of the lake or the landscape lake; the floating landscape aerobic devices are positioned in the lake or the landscape lake at intervals; the aquatic floating plants are distributed on the periphery of the lake or the landscape lake; and the cultured fishes are positioned in the lake or the landscape lake. The method mainly uses biological natural purification as a main method and mechanical purification as an auxiliary method, supplies power by using a clean carbon-free energy source, circularly increases the fluidity of a water body, can effectively purify polluted water, prevents phycophyta growth, improves the living environment of organisms in water and always retains aquatic oxygen content in a higher level. The invention has the advantages of simple operation, low treatment cost, low-carbon energy saving, no pollution, no noise, attractive appearance, environmental protection and good treatment effect.

The invention relates an artificial reef body suitable for aquaculture of the seafood, such as abalone and sea cucumber and the like, in particular to a multilayer combined type sea reef suitable for shallow seabed sowing aquaculture, which solves the problem of the lack of facilities dedicated for shallow seabed sowing aquaculture of abalone and sea cucumber. The sea reef body comprises a vertical column and at least two plates, wherein, the two plates are sheathed on the vertical column in a layering manner, and each layer of plate is sheathed with the vertical column through a rectangular hole; the top part of the vertical column is provided with a lifting pull ring. The facility is easily manufactured, and can provide three-dimensional perch space and shelter for aquaculture of the abalone and the sea cucumber; the reef body has wide and rough surface area for adhesion of various macrophytic algae and benthic microalgae, and is easy to form algal bed to provide adequate bait for the aquaculture of seafood; the reef body has moderate spacing, which is easy for batch harvest of aquaculture products. Aquaculture production of the seafood can be carried out in the sea region of shallow sand and mud substrate where lack of reef and is not suitable for seabed sowing aquaculture of the abalone and the sea cucumber by applying the facility, and the facility is beneficial for developing seafood aquaculture area and increases yield of the products.

The invention discloses a mariculture method based on an offshore wind plant. The method includes the following steps that firstly, single-pile type wind power foundations are inserted, a wind plant area is formed in an enclosed mode, and culture facilities are fixed among the wind power foundations; secondly, an equipment platform is arranged in the center of the wind plant area, reinforcing rods are connected between the equipment platform and the wind power foundations, and algal culture devices are fixed to the lower portions of the reinforcing rods to form an upper layer culture area; thirdly, fish culture net cages are fixed to the lower portions of the reinforcing rods to form a middle layer culture area; fourthly, shellfish culture net cages are arranged on single piles of the wind power foundations to form a lower layer culture area; fifthly, different seedlings are placed on the algal culture devices according to seasons; sixthly, fry are placed in the fish culture net cages, and algae falling from the upper layer culture area serve as bait; seventhly, shellfish are placed in the shellfish culture net cages, and algae left over by fishes and fish excrement serve as bait; eighthly, artificial fish reefs are placed at the bottom of the wind plant area and used for bottom sowing of shellfishes, fishes or shrimps and other organisms.
