Problems solved by technology

Although there have been more and more studies on the comprehensive utilization of fish scraps in recent years and some progress has been made, the overall application level has not improved significantly, and the main problems are: (1) Some research results are more or less flawed, such as Residue of fishy smell, loss of certain nutrients, etc.
For example, the acid-storage liquid fish protein prepared from fish leftovers is used as a feed additive for broiler chickens, layer hens, piglets, pork pigs and fish feed, but the product has a high moisture content of 80%, and storage and transportation needs Larger space; the composition of minerals, vitamins and other nutritional components of the product needs to be further studied; the source of fishy smell, trimethylamine, has not been significantly reduced, and the product still has a certain fishy smell
(2) Most of the researches are only for a certain kind of fish. Different fish species have different nutritional components, so the processing technology is naturally different. The processing technology of a certain kind of fish may not be suitable for another kind of fish; determine the best technological conditions for each kind of fish As well as reducing production costs and increasing added value still need a lot of research
(3) The traditional method of processing and utilizing fish scraps has more or less problems such as immature technology, low economic benefits, troublesome operation, long process flow, and large infrastructure investment.
[0005] In order to solve the shortcomings of the traditional utilization method of fish leftovers, the invention discloses an application method of fish leftovers in the cultivation of ginseng seedlings

Embodiment 2

[0048] Other steps are the same as in Example 1, the difference is that the disinfectant solution is made up of the following weight ratios: every 100 parts of 85% ethanol adds the following Chinese medicinal materials and auxiliary materials in parts by weight: 40 parts of Tujing bark, 20 parts of bar plate , 20 parts of Phellodendron, 10 parts of Sophora flavescens, 10 parts of Artemisia argyi leaves, 4 parts of auxiliary materials; the preparation method of disinfectant solution: chop the soil wattle bark, bark bark, Phellodendron flavescens, Sophora flavescens, and Artemisia argyi leaves separately, dry at 65°C, and then Grind to 70 meshes with a Chinese herbal medicine pulverizer for later use; respectively weigh 40 parts by weight of dried and pulverized Tujingpi, 20 parts of barbarum, 20 parts of Cortex Phellodendri, 10 parts of Sophora flavescens, and 10 parts of Artemisia argyi, and place After fully mixing in the Erlenmeyer flask, add 100 parts of 85% ethanol, soak fo...

Embodiment 3

[0054] Other steps are the same as in Example 1, the difference is that the disinfectant solution is made up of the following weight ratios: every 100 parts of 85% ethanol adds the following Chinese medicinal materials and auxiliary materials in parts by weight: 50 parts of Tujing skin, 25 parts of bar plate , 25 parts of Cortex Phellodendri, 15 parts of Sophora flavescens, 15 parts of Artemisia argyi leaves, 5 parts of auxiliary materials; the preparation method of disinfectant solution: chop the soil wattle bark, bark bark, Cortex flavescens, Sophora flavescens, and Artemisia argyi leaves respectively, dry them at 70°C, and then Grind them to 70 meshes with a Chinese herbal medicine pulverizer for later use; weigh 50 parts by weight of dried and pulverized Tujing bark, 25 parts of barbarum, 25 parts of Cortex Phellodendri, 15 parts of Sophora flavescens, and 15 parts of Artemisia argyi. After fully mixing in the Erlenmeyer flask, add 100 parts of 85% ethanol, soak for 48 hour...

Abstract

The invention discloses an application of fish leftover in thelenota ananas seedling culture, and belongs to the aquaculture field. Chaetoceros danicus is the most important and favorite bait of thelenota ananas seedlings in sea, and the quality and quantity of chaetoceros danicus are the key points of thelenota ananas seedling culture. In the conventional chaetoceros danicus culture, a formula, which is developed by the Zhanjiang Fisheries College, is adopted, and thelenota ananas seedlings are cultured in an open cement pool. The conventional method has the disadvantages of slow growth, easy pollution, high cost, low profit, inconvenient operation, and large workload. In the provided method, a white plastic barrel, which is aerated in advance, is used to culture the thelenota ananas seedlings. A culture is also provided and is composed of the following nutrients: fish leftover leachate, ammonium bicarbonate, potassium dihydrogen phosphate, sodium glutamate, urea, 920 plant growth stimulant, a vitamin S-3 solution, a M-F trace element solution, ferrous gluconate, soil leachate, and sea mud leachate. The growth speed and output of chaetoceros danicus are both greatly improved, moreover the culture method has the advantages of convenient operation, low cost, and high profit, and the yield is increased by 240%.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an application method of fish leftovers in raising ginseng seedlings. Background technique [0002] In the fish processing process, a large amount of leftovers will be produced, including fish heads, fish skins, fish fins, fish tails, fish bones and residual fish meat, which account for about 40-55% of the raw fish by weight. If it is not treated effectively, it will not only pollute the environment, but also waste a lot of nutrients. For example squid viscera contains 20%-30% crude fat, the gas chromatographic analysis result of its fatty acid composition shows: unsaturated fatty acid content is 86%, n-3 series fatty acid content is 37% (wherein EPA accounts for 12%, DHA accounts for 24%) %); silver carp fish head, fish skin, and fish bone spur mixture, the protein content is 14%, and the oil is 9.22%. Making full use of these leftovers can increase the added value of fi...
