Embodiment 1

[0008] Take a cage with a length and width of 3 meters * 3 meters, with a mesh of 2.5-3 centimeters, fix the bottom of the cage with wood, bamboo, plastic or metal materials to form a flat bottom, and place the cage in seawater at a depth of 10- In a sea area with a depth of 20 meters, the bottom of the cage is 5-10 meters from the bottom of the sea. In early March, 100 juvenile white pomfrets weighing 5 kg were released. At the same time, 3,000 juvenile pearl oysters and 10 kg of purple large red algae were released. Seawater salt was monitored during the process. degree, so that the seawater salinity range is between 1.018-1.025. When it rains, cover the net cage with plastic cloth to prevent the rainwater from directly pouring on the seaweed, or move the seaweed to the seawater layer with a depth of 5-10 meters to make the net cage float in the seawater. The seaweed on the sea surface is moved to the sea, and cultivated until mid-April, harvesting 500 kg of seaweed, and the ...

Embodiment 2

[0010] The cultivation method is the same as the embodiment, except that the fish species to be put in is grouper, the pearl oyster to be put in is white butterfly pearl oyster, and the seaweed to be put in is Kappa algae.

Embodiment 3

[0012] The breeding method is the same as that in Example 1, except that the fish species to be put in is turbot, the pearl oyster to be put in is Martensii oyster, and the seaweed to be put in is eel.

Abstract

The invention discloses a polyculture mode for marine products. Traditional marine product culturing modes are culturing modes of single varieties, fodder needs to be cast in the culturing process, the utilization rate of net cages is low, and the culturing cost is high. According to the polyculture mode for the marine products, pearl oysters and seaweeds are cast in a net cage in which fishes are cultured, the fishes, the pearl oysters and the seaweeds are cultured in the net cage together, the cast quantity of the pearl oysters meets the standard that a pearl oyster layer with the thickness of 10-12 cm is formed at the bottom of the net cage, and the quantity ratio of the cast quantity of the seaweeds to the cast quantity of the fish is 10 kilograms : 100-300 pieces, and the seaweeds meet the standard that the carrageenan content reaches 25-60%, the seaweeds are suitable for growing in the environment with the seawater temperature of 25-33 DEG C and the seawater salinity of 1.018-1.025 baume degrees. The three different cultured varieties can form a food chain in benign circulation, so that fodder does not need to be cast in the whole culturing process; by means of the food chain in benign circulation, a culturing sea area is made to be clean and environmentally friendly, the water body is clean, pest and disease damage is not prone to occurring, the culturing cost is low, and benefits are obvious.

Description

technical field [0001] The invention relates to a polyculture method for marine product cultivation, in particular to a polyculture method for fish, pearl oyster and seaweed, and belongs to the technical field of seawater cultivation. Background technique [0002] At present, mariculture is in the ascendant in our country. People make full use of the gift of the sea, change the traditional way of catching, and develop the mariculture industry through aquaculture. The types of mariculture include fish, shrimp, snail, crab, and sandworm. , shellfish and seaweed are all cultured in a single species. Fish are cultured in fish ponds or cages, shellfish are cultured in sea areas, ponds or cages, and seaweeds are cultured in shallow sea areas, Breeding in the breeding pond, separate farming, this farming method is the most conventional farming method, has become a common understanding of people, but this farming method, only a single species is harvested, and feed is needed during ...
