Problems solved by technology

[0002] In recent years, due to the single mode of offshore aquaculture, the aquaculture space cannot be comprehensively utilized, resulting in the lack of nutrients in sea areas dominated by algae.
In the sea area where abalone, sea cucumber and other animals are mainly farmed, the organic matter in the sea area increases due to the massive deposition of organic matter such as residual bait and feces, causing environmental pollution in the sea area

Embodiment 1

[0019] A method for shallow sea ecological culture of kelp, Gracilaria, wrinkled abalone, Ezoma manure sea urchin, and imitation japonicus, the method comprising the following steps:

[0020] (1) Select the breeding sea area: choose the sea area near Wawushi Village, Rongcheng, Weihai, choose a sandy bottom sea area with a water depth of 15m-20m, small water level drop, slow water flow, and reefs;

[0021] (2) Breeding distribution: In order to balance the nutrient salt in the sea area and facilitate the farming management, every 13 hectares of the sea area is divided into a breeding area, and the two adjacent breeding areas with the same area are respectively the algae breeding area and the abalone breeding area , so that the kelp and Gracilaria cultivated in the algae breeding area can make full use of the organic fertilizer produced in the cultivation process of wrinkled abalone, Ezoma manure sea urchin, and imitation japonicus, avoiding the eutrophication of the sea area, a...

Abstract

The present invention relates to the field of aquaculture, and particularly relates to a shallow sea ecological culture method for kelp, gracilaria, haliotis discus hanai, strongylocentrotus intermedius and apostichopus japonicus. The method comprises the specific steps of selecting a proper culture sea region; dividing the sea region into culture regions each with the area of 13 ha, wherein the two adjacent culture regions are an alga culture region and an abalone culture region respectively; and putting regular tetrahedron-shaped artificial fishing reefs at the bottoms of the alga culture region and the abalone culture region. The culture method effectively improves the system internal material and energy utilization efficiency, the annual production value per unit area is improved by 50% or above, the influence of culture production on the environment is effectively reduced, and ecological, efficient and low-carbon culture is realized.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for shallow sea ecological cultivation of kelp, Gracilaria, wrinkled pan abalone, Ezoma manure sea urchin and imitation japonicus. Background technique [0002] In recent years, due to the single mode of offshore farming, the breeding space cannot be comprehensively utilized, resulting in the lack of nutrients in sea areas dominated by algae. In the sea area where abalone, sea cucumber and other animals are mainly farmed, the organic matter in the sea area has increased due to the large amount of organic matter such as residual bait and feces deposited, resulting in environmental pollution in the sea area. Therefore, exploring an ecological, high-efficiency, and low-carbon aquaculture method through a reasonable combination of aquaculture organisms has become a good measure to realize the sustainable development of "high efficiency, high quality, ecology, health, and safety" i...
