Embodiment 1

[0020] A kind of sea urchin culture method, comprises the following steps:

[0021] 1) In February, sea urchin seedlings were cultured in natural seawater for 80-90 days at a water temperature of 18°C ​​and an illumination of 50,000 lux;

[0022] 2) Breed in a simulated seawater culture pond to avoid sea urchins from undergoing 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), broad bean powder 10% (w / w), scallop edge 5% (w / w), silkworm chrysalis powder 5% (w / w);

[0023] 3) Cultivate to a single sea urchin with an average wet weight of 80g, remove the middle sea urchin from the simulated seawater culture pond, put it into the natural seawater, and maintain the growth and development of the sea urchin by the plankton in the natural seawater;

[0024] 4) Cultivate until the average wet weight of a single sea urchin is 140g, and put the sea urchin from natural seawater into a simul...

Embodiment 2

[0031] A sea urchin cultivation method is characterized in that comprising the following steps:

[0032] 1) In February, sea urchin seedlings were cultured in natural seawater for 80-90 days at a water temperature of 20°C and an illumination of 80,000 lux;

[0033] 2) Breed in a simulated seawater culture pond to avoid sea urchins from undergoing 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), broad bean powder 10% (w / w), scallop edge 5% (w / w), silkworm chrysalis powder 5% (w / w);

[0034] 3) Cultivate to a single sea urchin with an average wet weight of 80g, remove the middle sea urchin from the simulated seawater culture pond, put it into natural seawater, and maintain the growth and development of the sea urchin by the plankton in the natural seawater;

[0035] 4) Cultivate until the average wet weight of a single sea urchin is 140g, and put the sea urchin from natural seawat...

Abstract

The invention provides a sea urchin culture method, which provides more favorable growth conditions for the growth of sea urchins by matching different culture environments in different seasons, and at the same time matches feed formulas with different components in combination with its physiological characteristics, thereby making The content of riboflavin in the body of sea urchin has been significantly improved, with excellent nutritional value and high added value. In addition, the method significantly promotes the growth and development of the seedling stage by controlling the illumination and temperature of the initial cultivation, thereby increasing the overall yield. The invention realizes outstanding technical effect through ingenious technical conception, and at the same time, the cost is low, and the process is easy to control, so it has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating sea urchins. Background technique [0002] Sea urchins are a class under the phylum Echinodermata, which are invertebrates that live in shallow waters of the ocean. The main feature is that the body is spherical, disc-shaped or heart-shaped, and there is no wrist. The endoskeleton heals together to form a solid shell, and most species have complex chewers in their mouths, called Aristotle's lanterns, which have teeth for chewing food. The alimentary canal is long and tubular, twists and turns in the body, and feeds on algae, hydra, and worms. Dioecious, individual development through sea urchin larvae (long arms), metamorphosis into juvenile sea urchins, after 1-2 years before reaching sexual maturity. It can be divided into two subclasses, regular Echinacea and irregular Echinacea, with 22 orders. There are more than 900 species, belonging to 225...
