Embodiment Construction

[0005] A method for cultivating sea cucumbers, comprising the following steps: placing the fertilized eggs of sea cucumbers in a hatching tank for hatching, and the hatching conditions are as follows: water temperature 16°C-19°C, salinity 29‰-32‰, water body pH value 7.8 ~8.5, the dissolved oxygen is more than 5 mg per liter of water, and the hatching density is 20 grains / ml to 50 grains / ml. After hatching and producing microtia larvae, the sea cucumber larvae are cultivated in the breeding pond. The conditions for larvae cultivation are: water temperature 20°C-25°C, room temperature 26°C-29°C, salinity 27‰-33‰, dissolved oxygen per The liter of water is 5-7mg, the PH value of the water is 7.8-8.3, the water is changed 1-2 times a day, and the amount of water changed each time is 1 / 3-1 / 2 of the overall water volume of the cultivation pool, and the temperature difference between before and after the water change is less than 3°C . The bait adopts single-celled algae, such as S...

Abstract

The invention aims to provide a method for breeding apostichopus japonicus selenka. The method comprises the following steps of: placing oosperms of the apostichopus japonicus selenka in an hatching slot for hatching; breeding apostichopus japonicus selenka larvae in a breading tank after small auricularia larvae are produced by hatching the oosperms; putting attaching bases for collecting young apostichopus japonicus selenka when 20 to 30 percent of the apostichopus japonicus selenka larvae grow into doliolaria larvae; and screening and taking the young apostichopus japonicus selenka out of the tank when the young apostichopus japonicus selenka grow to the length of between 2 and 4cm, and transferring the young apostichopus japonicus selenka into a pool for breeding. The apostichopus japonicus selenka bred in the pool is not required to be fed, and natural basic bait organisms brought by water changing are taken as feeds such as chlamydomonas and benthic diatoms primarily. The apostichopus japonicus selenka is harvested by an artificial diving fishing method when growing to the weight of between 4 pieces/kg and 6 pieces/kg.

Description

technical field [0001] The invention relates to a cultivation method of sea cucumbers. Background technique [0002] Sea cucumber has the characteristics of high protein, low fat and low sugar, and has high edible value and medicinal value. Due to the improvement of people's living standards, the demand for sea cucumber as a high-grade tonic is constantly increasing, and the output of sea cucumber is far from meeting the demand of the market. The cost of the existing cage culture method is relatively high. The development of sea cucumber farming industry has been limited. Therefore, to explore a low-cost, high-yield, and easy-to-promote sea cucumber cultivation method has become an urgent problem to be solved in sea cucumber cultivation. Contents of the invention [0003] The object of the present invention is to provide a sea cucumber cultivation method, which has the characteristics of low cost, high yield and easy popularization. [0004] A method for cultivating sea...
