A kind of artificial raising method of sargassum sargassum

Abstract

The invention discloses an artificial seedling-raising method of Sargassum holm, which includes collecting seed algae, promoting the early and synchronous maturation of female and male reproductive cells, promoting the early and synchronous discharge of germ cells in the female and male reproductive cells, collecting fertilized eggs and seedlings There are five steps in cultivation. The invention adopts a self-designed algae culturing device to promote the maturation and discharge of the algae reproductive receptacles under controllable conditions, so that the female and male reproductive receptacles can be matured in advance and synchronously, and the reproductive cells in the reproductive receptacles can be advanced and synchronized in advance and synchronously. Emission, the fertilization rate of egg cells reaches 90-95%, and the amount of seedlings is significantly increased; the seedlings are cultivated under controllable conditions, and the oyster shells are attached to the culture in the early stage of cultivation. 5cm, the seedling cultivation period is shorter than the whole process of attachment cultivation. The invention not only improves the utilization rate of water body obviously, but also shortens the seedling raising period by about 3 months compared with the traditional artificial seedling raising method, thereby improving the seedling raising efficiency.

Description

technical field [0001] The invention belongs to the technical field of artificial seedling cultivation of sargassum algae, and in particular relates to an artificial seedling raising method of sargasso algae. Background technique [0002] Sargassum whole ( Sargassum integer rimum Tseng et Lu, 2000) is a large brown alga endemic to China, belonging to Phaeophyta, Fucusaceae, and Sargassumaceae. The algae are dioecious and naturally grow in the rock marsh in the low tide zone, mainly in the coastal areas of Guangdong Province. Sargassum whole margin has high nutritional value and medicinal value. Along with its increasing market demand, natural Sargassum sargassum resources can no longer meet the market demand. Moreover, in recent years, the natural resources of Sargassum sargassum have also declined sharply due to damage from natural or human factors. Artificial breeding will become the main way to obtain Sargassum sargassum, and sufficient seed supply is a prerequisite f...

Problems solved by technology

According to the survey on the natural breeding habits of Sargassum sargassum, the algae growing in the natural sea area are generally fully mature in late May, and when the environmental conditions in the natural sea area are suitable in late October, the naturally bred seedlings begin to grow rapidly, so the artificial It is most suitable to transplant the bred seedlings to the sea area around the end of October. However, according to the current artificial breeding method of Sargassum, it usually takes 6-7 months from collection of seedlings to cultivation of seedlings larger than 5cm, which makes it impossible to grow the seedlings. Transplanting the seedlings to the natural sea area for cultivation at an appropriate time will inevitably affect the yield of Sargassum whole

[0005] It can be seen that the production of Sargassum algae seedlings according to the currently established Sargassum artificial seedling raising method inevitably has technical problems that need to be solved urgently, such as low seedling harvesting amount and long seedling raising cycle, which restrict the large-scale artificial breeding of Sargassum algae. production, seriously hinders the development of its large-scale commercial cultivation, so, in the process of artificial seedling cultivation of Sargassum sargassum, it is urgent to explore a method of raising seedlings that increases the amount of seedlings collected and shortens the seedling cultivation cycle, which is of great importance to promoting its large-scale commercial cultivation.
