[0022] 1. Seahorse breeding environment:

[0023] Carry out glass tank (0.8m*0.8m*0.8m) breeding, the breeding water is sand filtered seawater, and the breeding density is 20-100 fish / m 3 , semi-flowing water culture, the environmental conditions are controlled at water temperature 20-26°C, salinity 26-34°C, dissolved oxygen not less than 5.0mg / L, pH value 7.8-8.5, water depth 50-100cm, natural light, controlled by shade nets The maximum light intensity is not higher than 5000lux. The air pump is inflated, 1 air stone per cubic meter. Coral stones and plastic supports were placed underwater as seahorse entanglements.

[0024] 2, the preparation method of hippocampus frozen feed

[0025] (1) Live hairy shrimps are obtained from fishing off the coast of Guangdong, and they are temporarily raised in filtered sea water for 12 to 24 hours until the hairy shrimps completely empty out the bait in their bodies;

[0026] (2), according to the final concentration of 200mg / L, add nut...

Embodiment 2

[0030] 1. Seahorse breeding environment: the same as in Example 1.

[0031] 2, the preparation method of hippocampus frozen feed

[0032] (1) Live hairy shrimps are obtained from fishing off the coast of Guangdong, and they are temporarily raised in filtered sea water for 12 to 24 hours until the hairy shrimps completely empty out the bait in their bodies;

[0033] (2), adding nutritional enhancer according to the final concentration of 50mg / L, thereby carrying out nutritional enhancement to hairy shrimp, the breeding density of hairy shrimp is 1~5inds / mL, and strengthening time is 3~12 hours; Described nutritional enhancer According to the mass fraction of 100%, it includes 95% of spirulina dry powder and 5% of nutrient concentrate, which are mixed evenly to obtain the nutrient fortifier. The preparation method of the nutrient concentrate is to add fish oil, lecithin, vitamin A, vitamin C and vitamin E according to the mass ratio of 100:0.5:2:0.001:0.1, stir to obtain the co...

Abstract

The invention discloses a method for preparing a frozen sea horse feed. The method comprises the following steps: carrying out temporary feeding on living fairy shrimps or acete chinensis until the polypides or shrimp bodies completely discharge baits in vivo; adding a nutrient supplement according or a use amount of 50-200mg in each liter of seawater, so as to reinforce the nutrition of the fairy shrimps or acete chinensis, wherein the nutrient supplement comprises 95-98wt% of microalgae dry powder and 2-5wt% of a concentrated nutrient solution, and the nutrient supplement is obtained by uniformly mixing the microalgae dry powder with the concentrated nutrient solution; sterilizing the fairy shrimps or acete chinensis by using hydrogen peroxide after being reinforced and flushing the fairy shrimps or acete chinensis with fresh water, and removing dead individuals after the sterilizing and cleaning operations; and detearing the living fairy shrimps or acete chinensis, and directly freezing the living fairy shrimps or acete chinensis in a cold storage to obtain the frozen sea horse feed. Compared with common frozen baits, the frozen sea horse feed disclosed by the invention has the advantages of few germs, convenience for storage and transportation, and the like.

Description

technical field [0001] The invention belongs to the field of rare fish feed preparation methods, and in particular relates to a preparation method of seahorse frozen feed. Background technique [0002] Seahorses are precious traditional Chinese medicinal materials. Overfishing has led to a sharp decline in wild seahorses. With the increasing market price and demand for seahorses, the seahorse breeding industry has developed rapidly. At present, seahorses have been widely cultivated in coastal areas such as Guangdong, Guangxi, Hainan, Fujian, Shandong, Zhejiang, and Liaoning. The traditional seahorse breeding mode generally uses Artemia and mysis as the main bait for seahorse farming. These baits generally lack higher unsaturated fatty acids (HUFA). Insufficient nutrition greatly reduces the survival rate and growth rate of hippocampus, which is to a large extent It has also affected the development of the breeding industry of seahorses. According to the latest research at...
