Problems solved by technology

Since the main species of sea cucumber cultured in my country is sea cucumber in northern China, that is, sea cucumber imitation, most of the current sea cucumber compound feed research is aimed at this species, and there is no report on the compound feed research on sea cucumber

Embodiment 1

[0014] Example 1: To make 100 kg of compound feed, 10 kg of Sargassum powder, 10 kg of Sargassum powder, 10 kg of phylloxera powder, 40 kg of oyster shell powder, 10 kg of soybean protein, 5 kg of fish meal, and 10 kg of sea mud , 1 kg of shrimp bran, 0.5 kg of yeast powder, 0, 5 kg of immune polysaccharides, 1 kg of multivitamins, 1 kg of inorganic salt mixtures, 1 kg of binders. Weigh the components of the above weight, grind and mix them fully in a pulverizer, screen 100 mesh size, add water, granulate, and dry to make pellet feed.

Embodiment 2

[0015] Example 2: From October 26, 2012 to January 26, 2013, the experiment site was Liaoning Provincial Academy of Marine Fisheries Science. Select sea cucumbers with similar specifications as the experimental material. Use plastic baskets with black corrugated plates at the bottom of the baskets. The plastic baskets are suspended in the pool. Each basket contains 4-5 sea cucumbers. The water surface does not exceed the basket surface after each water change. To prevent the sea cucumbers from climbing out of the basket, use temperature-controlled heating equipment to keep the water temperature at 21±0.5°C. Different kinds of feed were prepared with seaweed powder, sea mud, soybean protein, and oyster shell powder as main ingredients. The feed composition is shown in Table 1. Each feed was fed to three baskets of sea cucumbers.

Abstract

The invention relates to a compound feed for sea cucumbers, in particular to a compound feed suitable for the growth and ripening of sea cucumbers. According to the characteristics of the food composition of the sea cucumber, the invention adds a high proportion of oyster shell powder as a main raw material to prepare a compound feed suitable for the sea cucumber. The feed comprises the following components (weight ratio): 10% of Sargassum powder, 10% of Sargassum powder, 10% of Zorophyllum powder, 10% of soybean protein, 40% of oyster shell powder, 5% of fish meal, and 10% of sea mud , shrimp bran 1%, yeast powder 0.5%, immune polysaccharide 0.5%, multivitamin 1%, inorganic salt mixture 1%, binder 1%. All raw materials are pulverized with a pulverizer, sieved with 100 meshes, fully mixed, added appropriate amount of water, granulated by a granulator, and dried into pelleted feed. The length of the pellets is 1-2 cm, and the diameter is 3-4 mm. The feed has no pollution, no residue, and no toxic side effects. Compared with the traditional sea cucumber feed, the proportion of oyster shell powder in the feed composition is increased to replace part of the seaweed powder, thereby reducing production costs. Apostichopus japonicus has good adaptability to this feed, and it can achieve good growth and ripening effects after feeding.

Description

Technical field [0001] The invention relates to a sea cucumber compound feed, which is characterized by a compound feed suitable for the growth and ripening of sea cucumber. Background technique [0002] Stichopus variegatus (Stichopus variegatus) belongs to the phylum Echinoderm, Class Sea Cucumbers, Fistulas, Stichopaceae, and Stichopus genus. Stichopus stichopus is distributed in the coastal areas of Guangxi, Guangdong, Nansha Islands, Hainan Island, Leizhou Peninsula and other coastal areas in my country. It has the characteristics of high nutritional value, high temperature resistance, and fast growth. It is one of the high-quality edible sea cucumbers produced in southern my country. It is also a popular food and medicinal material in Southeast Asia, and is the main target for the development of sea cucumber farming in the South. [0003] Since the breakthrough of artificial breeding technology of sea cucumber at the end of last century, sea cucumber aquaculture in my country...
