Embodiment 1

[0037] 1) Selection and transportation of sargassum-grown vegetables: In the southern region, the maturity of the algae is determined by microscopic examination of the reproductive tray, and the sargassum-grown vegetables harvested from the sea are directly loaded into the incubator before the peak maturity period arrives. and use seawater ice bottles to keep the temperature low, properly pour in seawater to ensure that the sargassum grow vegetables are moist, and then cover the incubator and seal it to transport to the destination in the north;

[0038] 2) Pretreatment of sargassum growing vegetables: the sargassum grown vegetables brought back from the south are cleaned in a seawater pool, and the sargassum branches with reproductive trays are selected, and re-clamped into seedling ropes and hung in the indoor workshop On the surface of the pool, hang 3 ropes of 8-15kg per pool, and the ratio of male to female of the hanging vegetables is 4-8:1. Carry out flowing water aerati...

Embodiment 2

[0050] The method that the present invention carries out picking seedlings and cultivating in southern regions is that described method is carried out according to the following steps:

[0051] 1) Picking seedlings: In southern regions, such as Dongtou County, Zhejiang Province, select the local sea surface to artificially clip seedlings and raise the mature algae of Sargassum as seedlings to collect seedlings;

[0052] 2) Collection of fertilized eggs: After fully washing the mature sargassum vegetables, spread them evenly in the pool where the seedling curtains have been arranged in advance. Each seedling curtain uses 0.4-0.6kg of female sargassum vegetables, and the male seeds Vegetables are matched in a ratio of 4 to 8:1, and the fertilized eggs are collected in still water. During this process, the seawater is constantly stirred or the vegetables are turned over, so that the fertilized eggs fall off quickly and attach evenly. The attachment time of the fertilized eggs last...

Abstract

The invention provides a method for large scale early bred fingerlings of northern sea area sargassum thunbergii, which is characterized in that, in the middle and last ten days of May, early matured sea surface rafting algae seedlings in south are chosen; the algae seedlings are transported to northern sea area after long-distance transportation; in an indoor seedling workshop, pretreatment and seedling collection are performed to algae seedlings; after the algae seedlings are cultured indoor for about ten days, rafting temporary rearing seedling emergence is carried out in sea, meanwhile standardized sea management is performed; after the marine cultivation of about two months, more than 4cm large sized robust sargassum thunbergii seedlings are obtained.

Description

technical field [0001] The invention relates to a method for growing seaweed seedlings, in particular to a method for growing large-scale seedlings of sargassum in advance. Background technique [0002] Sargassum thunbergii is a common wild species of brown algae in the coast of my country, which has important economic value. In my country, it is distributed from the Liaodong Peninsula in the north to the Leizhou Peninsula in the south, and its traces are all over Liaoning, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong and other provinces. With the deepening of its research in recent years, some important functions of Sargassum have been gradually discovered: in addition to occupying an important position in the marine ecosystem, it also has many exploitable potentials in medicine, health care, aquaculture and chemical industry. potential. [0003] At present, with the vigorous development of the sea cucumber and abalone aquaculture industry, the wild resources of sargass...
