Embodiment

[0033] Take Huludao coastal waters aquaculture in Liaoning as an example.

[0034] ①, spring breeding, from March to May, sea cucumber seedlings are stocked in simulated seawater culture ponds, and the water temperature is kept between 15 and 20°C. From 500 heads per kilogram to 50 grams per kilogram, the survival rate has reached more than 80%.

[0035] ②, summer breeding, from June to July, fish out the small sea cucumbers that have grown larger from the simulated sea culture ponds, put them into the natural sea culture ponds, grow and develop by natural plankton, and become medium sea cucumbers. When the natural seawater temperature reached 30°C, the sea cucumbers were fished out from the natural seawater and put into simulated seawater culture ponds for cultivation to avoid aestivation of sea cucumbers.

[0036] ③. Autumn cultivation. From August to October, when the natural seawater temperature drops to 20°C, remove sea cucumbers from the simulated seawater culture pond ...

Abstract

The invention discloses a culture method of sea cucumber in the aquiculture field. A simulative seawater-culture pond and a natural seawater-culture pond are arranged. An arched shed is arranged above the simulative seawater-culture pond and is covered with a diaphanous film and a shady covering. The water used in the simulative seawater-culture pond is prepared by blending natural sea water with seaside well water containing salt, the salt content of the water ranges from 2.9% to 3.6%, and the water temperature is adjusted by controlling the proportion of the natural water to the seaside well water containing salt. Through the stages of spring culture, summer culture, autumn culture and winter culture, the method can avoid the aestivation and hibernation of sea cucumber, thus realizing the perennial growth and development of sea cucumber; compared with the natural aquiculture, the yield is enhanced. The method is applicable to the artificial culture of sea cucumber.

Description

technical field [0001] The invention proposes a method for cultivating sea cucumbers in the field of aquaculture. Background technique [0002] Before the present invention was proposed, sea cucumbers were usually cultured as aquatic products to grow naturally in seawater to obtain sea cucumber products. However, when sea cucumbers are cultured in seawater, the temperature is high in summer, and the sea cucumbers go into aestivation. In winter, when the weather is cold, the sea cucumbers go into hibernation. Sea cucumbers stop growing during estivation and hibernation, affecting yield. [0003] The patent number is 20071014607.21, a deep-water well greenhouse sea cucumber cultivation method, characterized in that: using the existing deep-water well greenhouse for industrialized cultivation of sea cucumbers, the specific cultivation methods include: [0004] (1) Seed stocking [0005] The size of the seedlings is 3cm-5cm, and the stocking density in the early stage of bree...
