Embodiment 1

[0046] Embodiment 1. Ripe Sargassum planting vegetables are put into the filter screen 5 of the stirring tank, and the valve 10 of the collecting port is closed. Open the seawater filter 2 and its inlet valve 1, and after injecting an appropriate amount of seawater into the stirring tank 14, close the seawater filter 2 and its inlet valve 1. Regulate the rotating speed of the stirring blade 9 through the vortex type rotary agitator 8 according to the maturity of the vegetables, and set the stirring time interval for the vortex type rotary agitator 8 according to the release situation. Simultaneously, the temperature digital panel 6 is turned on, and the water temperature in the fertilized egg collection process is monitored in real time through the temperature probe 7 . When the density of the fertilized eggs released by planting vegetables reaches the collection requirement, the temperature digital panel 6 and the vortex type rotary agitator 8 are turned off. Open the collec...

Embodiment 2

[0048] The collection method of sargassum is carried out according to the following steps:

[0049] ①. Open the seawater filter inlet valve 1 to filter the seawater to rinse the mixing tank and the filter screen of the mixing tank, open the collection port valve 10, rinse the inner wall of the second collector filter screen 11, 12 and collector 13, and repeatedly clean the container 3 times, close the seawater filter inlet valve 1, and empty the cleaned seawater;

[0050] ②, select mature sargassum to grow vegetables and put them into the filter screen 5 of the stirring tank according to the male to female ratio of 6:1, and close the collection port valve 10;

[0051] ③. Open the inlet valve 1 of the seawater filter, inject an appropriate amount of seawater into the stirring tank 4, and then close the inlet valve 1 of the seawater filter.

[0052] ④. Turn on the temperature digital panel 6 at the same time, and monitor the water temperature in real time during the fertilized ...

Embodiment 3

[0060] The collection method of hijiki is carried out according to the following steps:

[0061] ①. Open the seawater filter inlet valve 1 to filter the seawater to rinse the mixing tank and the filter screen of the mixing tank, open the collection port valve 10, rinse the inner wall of the second collector filter screen 11, 12 and collector 13, and repeatedly clean the container 2 times, close the seawater filter inlet valve 1, and empty the cleaned seawater;

[0062] ②, select mature hijiki planting vegetables and put them into the filter screen 5 of the stirring tank according to the ratio of male to female of 8:1, and close the valve 10 of the collection port;

[0063] ③. Open the inlet valve 1 of the seawater filter, inject an appropriate amount of seawater into the stirring tank 4, and then close the inlet valve 1 of the seawater filter.

[0064] ④. Turn on the temperature digital panel 6 at the same time, and monitor the water temperature in real time during the fertil...

Abstract

The invention provides a device and method for efficiently collecting sargassum fertilized eggs. The device comprises a seawater filter device, a stirring device and a collector, wherein the stirring device comprises a stirring tank and a stirrer; the stirrer is arranged below the stirring tank; a stirring blade of the stirrer is arranged in the stirring tank; a stirring tank filter screen is arranged in the stirring tank; a colleting opening valve is arranged at the bottom or on the side of the bottom of the stirring tank; the collector is arranged below the colleting opening valve; and the collector is provided with at least two collector filter screens inside. By adopting the device and the method, the problems of low degree of mechanization, high labor intensity, intensive labor time,small seedling culture scale, low utilization ratio of seed resources and the like in the seedling collection process in the prior art are solved.

Description

technical field [0001] The invention belongs to the mariculture industry, and in particular relates to a device for collecting fertilized eggs of seaweed, in particular to a device and method for efficiently collecting fertilized eggs of Sargassum family seaweed. Background technique [0002] Sargassum in seaweed is an important economical algae. In recent years, many scientific research and production practices have been carried out around the artificial breeding of Sargassum. The artificial breeding technology of Sargassum is based on the sexual reproduction of Sargassum, and the mature algae are cultivated by collecting and releasing fertilized eggs. This technology has been basically successful, and is currently in the stage of application and promotion, and has a good application prospect. [0003] The collection of fertilized eggs of S. sargassum is one of the key links in the process of artificial cultivation of sargassum. This process directly affects the emergence ...
