Embodiment 1

[0030] In this embodiment, a method for polyculture of seaweed and rock sea bream, where the seaweed is Gracilaria, includes the following steps:

[0031] 1. Selection of Gracilaria fry and stone sea bream fry: choose Gracilaria fry with a length of 7 cm or more; choose stone sea bream fry with an average body length of 8 cm and a weight of 10 g;

[0032] 2. Preliminary preparations for stocking: build a breeding pond on the coast of Guangzhou: an area of ​​40m 2 The depth of the pool is about 1.5 meters. The bottom quality is preferably sandy or sandy. Excavate into the drainage ditch. Set up 2 water inlets at the side of the pool, which are fresh water and sea water inlets, and make them face the same direction. Convenient water inlet and drainage;

[0033] 3. Construction of the environmental parameters of the breeding pond: clean the pond, use bleach powder to disinfect the pond about one month before stocking; pass fresh sea water into the pond about half a month before stocking...

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. [...
