Embodiment 1

[0021] A method for cultivating sea cucumbers, comprising the steps of:

[0022] 1) In February, sea cucumber seedlings were cultured in natural seawater for 80-90 days at a water temperature of 18°C ​​and an illumination of 50,000 lux;

[0023] 2) Breed in a simulated seawater culture pond to avoid sea cucumbers from aestivation. During this period, the feed ingredients are: kelp powder 40% (w / w), fish meal 15% (w / w), brown algae 15% (w / w) , Sargassum 10% (w / w), yeast powder 10% (w / w), scallop edge 5% (w / w), silkworm chrysalis powder 5% (w / w);

[0024] 3) When the natural seawater temperature drops to 22°C, remove the sea cucumber from the simulated seawater culture pond, put it into the natural seawater, and rely on the plankton in the natural seawater to maintain the growth and development of the sea cucumber;

[0025] 4) When the natural seawater temperature drops below 10°C, put the sea cucumber from the natural seawater into the simulated seawater culture pond for culti...

Embodiment 3

[0038] A method for cultivating sea cucumbers, comprising the steps of:

[0039] 1) In February, sea cucumber seedlings were cultured in natural seawater for 80-90 days at a water temperature of 19°C and an illumination of 60,000 lux;

[0040] 2) Breed in a simulated seawater culture pond to avoid sea cucumbers from aestivation. During this period, the feed ingredients are: kelp powder 40% (w / w), fish meal 15% (w / w), brown algae 15% (w / w) , Sargassum 10% (w / w), yeast powder 10% (w / w), scallop edge 5% (w / w), silkworm chrysalis powder 5% (w / w);

[0041] 3) When the natural seawater temperature drops to 22°C, remove the sea cucumber from the simulated seawater culture pond, put it into the natural seawater, and rely on the plankton in the natural seawater to maintain the growth and development of the sea cucumber;

Abstract

The invention provides a culture method capable of improving nutritional components of sea cucumbers. The method is characterized in that different culture environments matching different seasons provide more favorable production conditions for the growth of sea cucumbers; based on the physiological characteristics of sea cucumbers, feed formulas with different ingredients are provided, so that the content of arginine in the bodies of sea cucumbers increases remarkably and especially the content of L-arginine is outstanding. Such sea cucumbers are called golden cucumbers on the market, having an excellent nutritional value and an extremely high additional value. By controlling the illumination and temperature in early-stage culture, the growth and development in the hatchling period of sea cucumbers are remarkably promoted, so that the overall yield is increased. The method achieves outstanding technical effects through smart technical conceptions and has the advantages of low cost and easy control of process, thereby having a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a cultivation method for improving the nutritional components of sea cucumbers. Background technique [0002] Sea cucumber is a marine echinoderm that lives on the seashore to 8,000 meters. It has a history of more than 600 million years. Sea cucumbers feed on seabed algae and plankton. Sea cucumbers are covered with thorns and are widely distributed in oceans all over the world. There are many kinds of sea cucumbers along the coast of the South my country Sea. There are more than 20 kinds of sea cucumbers available for consumption. Sea cucumbers are as famous as ginseng, bird's nest and shark's fin, and are one of the eight treasures in the world. Sea cucumber is not only a precious food, but also a valuable medicinal material. According to the records in "Compendium of Materia Medica": Sea cucumbers are sweet and salty, tonify the kidneys, benefit the essence, take urine,...
