Embodiment 1

[0034]From March 2009 to April 2010, artificial breeding, cultivation and research on main predators were carried out at the Donghai Island Marine Biology Research Base and Zhanjiang Liusha Bay. Using nylon cloth seedling curtain as the attachment base to artificially attach seedlings, the indoor and sea areas were combined to cultivate young sporophytic seedlings, the early development process and growth of seedlings were observed, and the artificial seedling cultivation technology was explored. Thousands of plants. 2 acres of Sargassum Naozhou were cultivated in full floating raft mode, and the growth length of the cultivated algae was regularly measured, and the cultivation yield was 1700 kg / Km seedling rope with a fresh weight. Cultivation in the diurnal tidal sea area with shallow water layer and high water temperature (maximum 33.7 ℃) is conducive to the maturation of reproductive trays, which is at least one month earlier than the algae growing naturally.

Embodiment 2

[0036] From January 2010 to December 2011, this method was used to raise Sargassum seedlings and supply seedlings, and 21 mu and 20 mu of Sargassum artificial marine pastures were built in Zhuzhou Island, Maoming and Naozhou Island, Zhanjiang, respectively.

Embodiment 3

[0038] From January 2011 to May 2012, 20 mu of Sargassum seedlings were cultivated in Haishitan Sea Turtle Breeding and Protection Center of Naozhou Island, Zhanjiang, in order to solve the problem of sea turtle feed, with a fresh weight of 3500 kg / Km. Seedling rope, the total dry product output is 7 tons, and the output value is 40,000 yuan.

Abstract

The invention relates to an artificial seedling raising and cultivating method of edible sargassum.naozhouense. According to the method, a cement pit is taken as a seedling raising field, and adopted seawater is filtered and disinfected; a nylon seedling curtain is taken as an adherence for artificial spatfall, seed sargassum.naozhouense in a propagation period is selected for seedling picking and is turned manually every 4-5 hours during the seedling picking process; during the cultivating period, the seawater is used to flush mixed algaes and sludges on the seedling curtain at regular intervals, and the seawater in the pit is changed every 3 days and is added with nutrient salt; the seedlings are clamped and put in a sea area to be cultivated when growing to about 5 centimeters long; the cultivation yield is 1700kg / Km of fresh weight each seedling rope; and the seedlings are cultivated in diurnal tide sea areas with shallow water layer and higher water temperature (the maximum of which is 33.7 DEG C), thus being beneficial to the maturity of archegoniophore, and the maturity of the archegoniophore is earlier than that of the naturally growing algae by at least one month. The artificial seedling raising and cultivating method can be applied to artificial seedling raising and cultivating of the sargassum.naozhouense in a large scale, and is also an effective method for protecting and reproducing the natural resources of the sargassum.naozhouense, and the cultivated product is used for realizing commercial purposes of food, medicine, fertilizer, feed, seaweed industry and the like.

Description

technical field [0001] The invention relates to an artificial seedling raising and preparation method of large economical seaweed, in particular to an artificial seedling raising and cultivation method of edible sargassum, belonging to the field of aquaculture. Background technique [0002] my country is a big seaweed breeding country in the world, and the main cultivated species are kelp, wakame, striped laver, altar laver, asparagus, hijiki, etc. The development of seedling breeding and cultivation of large brown algae Sargassum can increase the number of new species of seaweed cultivation in our country . [0003] There are more than 400 species of Sargassum reported in the world, widely distributed in tropical and temperate waters. Among the species of Fucus in China, the genus Sargassum has the most species, with a total of 130 species. There are 39 species recorded in Guangdong Province. The biomass ranks first among large seaweeds. It is known as the seabed fores...
