Embodiment 1

[0021] On June 1, 2019, the present invention was used to carry out a pond ecological cultivation test of scutellaria and oyster seedlings near the river. The cultivation time was 60 days, in which 2 crops of oyster seedlings were cultivated, and 1 crop of scutellaria was cultivated in the middle. The specific implementation process is as follows:

[0022] (1) Pond selection: The outdoor hard-bottomed cement pond with an area of ​​200m was selected in the bamboo forest seawater breeding test base of the Institute of Oceanography of Guangxi Zhuang Autonomous Region. 2 , The depth of the pool is 150cm, rectangular, with inlet and outlet outlets on the diagonal, which is convenient for inlet and outlet.

[0023] (2) Prepare infrastructure: use four horizontal pipes to build a "well"-shaped metal pipe culture skeleton in the pond, and fix the two ends of the horizontal pipes on the cement pool wall with expansion screws, and weld and fix them with vertical pipes below the intersec...

Abstract

The invention discloses a three-dimensional ecological pond cultivation method for sipunculus nudus and crassostrea rivularis fries. The method comprises the steps of selecting a pond; preparing infrastructure; water inflowing into the pond; stocking young sipunculus nudus; arranging an oyster fry attaching device; stocking oyster larvae; performing daily management; and performing seedling emergence. The pond culture space is fully utilized, sipunculus nudus large-size medium-culture fries are cultured on the bottom layer, and oyster fries are cultured on the upper layer. Bait is provided forsipunculus nudus fries by using oyster fry excrement, organic particle sediments, benthic microorganisms and the like; by utilizing the purification function of sipunculus nudus on a substrate, a good ecological environment is provided for oyster fries, smooth implementation of outdoor pond batch fry cultivation is guaranteed, a sipunculus nudus-oyster pond fry breeding ecological system with complementary ecological niche and function is constructed, a three-dimensional efficient ecological fry breeding mode is realized, and the production efficiency and the economic benefit are greatly improved.

Description

technical field [0001] The invention relates to a three-dimensional ecological cultivation method in a pond for seedlings of the square star worm and near river oysters, and belongs to the technical field of marine aquaculture and breeding. Background technique [0002] Sipunculus nudus, also known as naked square starworm, commonly known as "sandworm", has high nutritional value and medicinal value. It is one of the most popular seafood varieties and is an important name in southern my country. Special treasures. The gridworm mainly lives in burrows, and its natural habitat is mainly in intertidal tidal flats on coastal sandy or sandy muddy bottoms. It mainly feeds on organic debris, microorganisms, and benthic diatoms in muddy sandy bottoms. In recent years, with the continuous expansion of the tidal flat breeding scale of the square starworm, it has developed into an important new species of mariculture in Guangdong, Guangxi, Fujian, Hainan and other coastal areas. At the...
