Method for polyculture of seaweed and striped beakfish

Abstract

The invention discloses a method for polyculture of seaweed and striped beakfish. The method comprises the following steps of culture pond environmental parameter establishment, wherein the salt degree of water is 5%o-35%o, PH value ranges from seven to nine, and the depth of the water is 50 cm-80 cm; polyculture, wherein seaweed seedlings are put into a culture pond, striped beakfish fries are put into the culture pond after 10 to 20 days, and the culture density of the striped beakfish fries is eight to ten tails per square meter; ecological management, wherein the water is changed one to two times a week, the transparent degree of the water is no less than 40 cm, and a culture pond environmental parameter is maintained; harvest, wherein the polyculture time is four to five months, the seaweed is harvested by two to three times in the period, the striped beakfish and the surplus seaweed are harvested after four to five months, and culture is completed. According to the method, the seaweed is used for being mixedly cultured with the striped beakfish, the stripped beakfish and the seaweed both have high nutrition value and economic value, and therefore the economic benefits of a polyculture system are guaranteed. According to the polyculture technique, the water can be effectively avoided from being polluted, the eutrophication of the water can be avoided from occurring, and the method has high ecological benefits.

Description

Technical field [0001] The present invention relates to the technical field of polyculture, in particular to a method for polyculture of seaweed and rock sea bream. Background technique [0002] Seaweed is a kind of seaweed that grows in the sea. It is a cryptographic plant in the plant kingdom. Seaweed contains a large amount of iodine that can significantly reduce the cholesterol content in the blood. Regular eating is beneficial to maintaining the function of the cardiovascular system, making blood vessels elastic and rich in vitamins. It can maintain the healthy growth of epithelial tissue, reduce pigment spots, and has medicinal values ​​such as anti-hyperthyroidism, anti-virus, anti-cancer, anti-cancer, and prevention of leukemia. [0003] In the cultivation process of seaweed, to achieve high yield, the nutrient content in the water is very important. Single cultivation of seaweed needs to apply enough base fertilizer to the water, which leads to higher cultivation costs. [...

The single-species farming model wastes water space and affects the economic and ecological benefits of farming

And polyculture can make full use of the space of the water body, but for unreasonable polyculture, it is easy to cause mutual cannibalism, such as the polyculture of crabs, often leads to cannibalism, and even causes damage to the mixed fish and shrimp, and There are still many deficiencies in ensuring the ecological and economic benefits of the polyculture system
