Embodiment Construction

[0029] The present invention is further discussed below through specific examples, but those skilled in the art should know that the examples do not limit the scope of the patent protection of the present invention in any way, and those skilled in the art will understand the invention without changing the thinking of the present invention. The modification or transformation of the technical solution shall be included in the scope of protection of this patent.

[0030] Sea millet of the present invention and sea cucumber cofferdam polyculture method specifically comprise the following steps:

[0031]1. Cofferdam construction: The cofferdam requires that the area of ​​the cofferdam be no less than 0.5 hectares, the bottom of the cofferdam should be gravel or rock reef, and the water depth of the cofferdam should be 2 to 3 meters. The daily water change capacity is above 10%, and the number of days when the water temperature is between 1 and 23°C is not less than 200 days per yea...

Abstract

The invention relates to a three-dimensional cofferdam culture method for ginatesargassum kjellmanianum and sea cucumbers, and belongs to the field of aquaculture. For solving a plurality of problems such as water body eutrophication, low dissolved oxygen content, high illumination and bad bottom substrates which exist in the traditional single culture variety culturing process, a three-dimensional cofferdam culture method for the ginatesargassum kjellmanianum and the sea cucumbers is established by integrating the technical advantages of seaweed culturing and the technical advantages of sea cucumber culturing and learning from each other. The method comprises the steps of cofferdam building, culture environment adjusting, fry putting, culture managing, product harvesting and the like. Related experiments show that polyculture of the ginatesargassum kjellmanianum and the sea cucumbers is beneficial for improving the culture water body environment, improving the culture quality of the sea cucumbers, increasing the yield of the sea cucumbers and transforming from a traditional extensive aquaculture mode to an intensive aquaculture mode.

Description

technical field [0001] The invention relates to a method for polyculture of sea millet and sea cucumber cofferdams, belonging to the field of aquaculture. Background technique [0002] In recent years, due to the improvement of people's living standards, the demand for sea cucumbers has also increased. However, due to the serious pollution of the surrounding sea areas in my country, and sea cucumbers have extremely high requirements for the water environment, farmers can only turn to indoor breeding. Although wild Sea cucumber cultivation began to decline, but indoor cultivation is booming. Due to the rise of indoor cultivation, the output of sea cucumbers in my country has increased rapidly. [0003] Cofferdam cultivation of sea cucumber refers to the construction of dikes and cofferdams in suitable inner bays in combination with the trend of rocks and the characteristics of the mouth of the bay. In addition, dikes and cofferdams can also be built according to the terrain i...
