example 1

[0038] In 2003, we conducted a high-density artificial feeding experiment of jellyfish in Shandong Haodangjia Feed Factory. According to the test results, combined with the water quality and environmental conditions of the culture, the feed formula was adjusted. The specific ratio (by percentage) was: fish meal 48%, shrimp meal 5%, peanut meal 15%, seaweed powder 4%, feed yeast 5% %, starch 11%, fish oil 4%, choline chloride 0.5%, biological enzyme 4%, lecithin 0.4%, multi-vitamin additive 1.6%, multi-mineral additive 1.5%.

[0039] The feed factory of the breeding enterprise purchases various feed raw materials in proportion, mixes and crushes them according to the ratio, and makes them into small pellets with a particle size of 1 mm to 5 mm, which are floating, and feed them. The suspension time of small pellets can reach about 30 minutes.

[0040] At the end of the test, the experts checked and accepted on site. The results of the experiment are: 274 mu of high-density bree...

[0042]In 2003, the cooperative research on jellyfish breeding technology was carried out at Rongxing Farm, Dawa County, Panjin City, Liaoning Province. By providing formulas to guide the production of jellyfish feed, Rongxing Farm purchased feed raw materials according to the feed formula, and carried out processes such as crushing, bonding, stirring, and dilution. Processing, producing small pellet feed with good stability and long suspension time to feed jellyfish. The test feed formula (in percentage) is: fish meal 42%, shrimp meal 6%, soybean meal 16%, seaweed meal 6%, feed yeast 6% , 13% starch, 3% fish oil, 0.4% choline chloride, 5% biological enzyme, 0.2% lecithin, 1.0% multi-vitamin additive, 1.4% multi-mineral additive.

[0043] A total of 200 mu of jellyfish breeding was tested. At the end of the test, experts conducted on-site acceptance and Dawa County newspaper reports. The acceptance results were: the average umbrella diameter of jellyfish was 32.6cm, and the weig...

Abstract

The invention relates to a formula of an artificial compound feed for jellyfish and the mixture ratios of the ingredients thereof are 30-60 percent of fishmeal, 1-8 percent of shrimp meal, 0-30 percent of soybean meal and peanut meal, 1-8 percent of dried marine algae powder, 1-10 percent of fodder yeast, 5-26 percent of starch, 1-10 percent of fish oil, 0.1-1.0 percent of choline chloride, 1-10 percent of enzyme, 0.1-1.0 percent of lecithin, 0.1-3 percent of complex vitamin additive and 0.1-3 percent of complex mineral additive. The formula has stable raw material source and balanced nutrition proportions, is scientific and practical; feed granules have good stability, and the suspension time can reach more than 15 minutes. Productive practice of cultivation shows that the culture density is larger than 300 per mu, the cultivated jellyfish has good quality and improved body color; each jellyfish cultured by the invention has the effects that: average diameter of the umbrella-part is 37.6 plus or minus 5 cm; average weight is 5.27 plus or minus 2.61 kg; the yield rate of jellyfish processing is increased by 15 percent. The invention can be applied in the mass production of feed for jellyfish, can satisfy the nutrition requirements of jellyfish in culture, and ensures the sustainable development of jellyfish cultivation industry.

Description

Technical field: [0001] The invention belongs to the preparation technology of artificial compound feed for aquaculture, and is a formula for producing artificial compound feed that meets the nutrient requirements for the normal growth of jellyfish during the artificial breeding process of jellyfish. Background technique: [0002] In order to ensure the normal growth of breeding organisms and promote the healthy development of the breeding industry, along with the research on the nutritional requirements of various new varieties, their artificial compound feeds have also been applied. [0003] Since the artificial breeding of jellyfish seed was successful in the 1990s, my country has started the research on artificial breeding technology of jellyfish. At present, the production of jellyfish artificial breeding is distributed in coastal waters from Liaoning to Guangxi in my country; but after more than ten years of experiments, so far, the cultivation of jellyfish mainly reli...
