Problems solved by technology

[0005] At present, the common diseases in mandarin fish culture mainly include bacterial gill rot caused by cellulophilus columnar, bacterial sepsis caused by Aeromonas hydrophila, white skin disease caused by flexrobacter columnar and Saprolegniasis caused by saprolegniasis, etc., the above diseases are seriously endangering the development of mandarin fish aquaculture, lack of effective preventive measures in the current culture, and there is no direct and effective medicine to treat after the onset, often wasting a large amount of medicine and still Failure to suppress the spread of the disease, resulting in double economic losses
The existing aquaculture technology mainly relies on water disinfection and antibiotic treatment for prevention and treatment, but this prevention and control method cannot effectively prevent the occurrence and spread of diseases, and it will also cause water pollution and water quality deterioration. The use also leads to the increase of antibiotic-resistant bacteria, making it more difficult to cure diseases, and antibiotic residues also affect the health of consumers

[0017] Example 2 : A special feed additive for mandarin fish breeding, prepared from the following raw materials in parts by weight: 28 parts of Pteris chinensis, 15 parts of Buttercup, 35 parts of Guanzhong, 5 parts of Baibu, 30 parts of Andrographis paniculata, 5 parts of Polygonum japonica, Chinese yam 25 parts, 15 parts of licorice, 10 parts of white peony, 9 parts of peony bark, 32 parts of paulownia leaves, 25 parts of earthworm, 5 parts of mulberry bark, 18 parts of carrot, 34 parts of kelp; the special feed additive for mandarin fish breeding The preparation method is as follows: take Pteris vulgaris, Ranunculus, Guanzhong, Libu, Andrographis paniculata, Polygonum japonica, Chinese yam, Licorice, Radix Paeoniae Alba, Cortex Moutan, Paulownia leaf, Earthworm, Morus alba, Carrot and Raw materials such as kombu are mixed and pulverized to 60-80 mesh with a pulverizer, and mixed thoroughly to obtain the special feed additive for mandarin fish breeding of the present inven...

Embodiment 3

[0018] Example 3 : Mandarin fish breeding experiment

[0019] Mandarin fish cultured in 2mX2m cages were used for breeding experiments. The cages were set up in a river bay with no pollution sources around and a water depth of about 5m. The water surface is relatively wide, the bottom is flat, the water flow is smooth, sheltered from the wind and sunny, the water level is relatively stable, and the water quality is fresh. . The transparency of the water body is about 50cm, the pH value is 7.4-8.2, and the dissolved oxygen content is above 5.1mg / L. The length of mandarin fish entering the box is 8-9cm, and the stocking density is 50 fish per square meter of water area, that is, 200 fish are stocked in each cage, and fed with compound feed. A total of 5 cages were used in the experiment. Cage 1 was the blank control group, which was fed with conventional commercially available mandarin fish compound feed; cages 2-3 were the test groups, and the feed fed by them was the conven...

Abstract

The invention relates to a special feed additive for cultivating siniperca chuatsi. The special feed additive is prepared from following raw materials in parts by weight: 20-30 parts of herba pteridis multifidae, 13-15 parts of ranunculus acris, 30-35 parts of cyrtomium fortunei, 5-10 parts of stemona sessilifolia, 20-30 parts of andrographis paniculata, 5-7 parts of polygonum flaccidum meissn, 25-30 parts of Chinese yams, 12-15 parts of glycyrrhiza uralensis, 10-15 parts of white paeony roots, 7-9 parts of moutan barks, 32-35 parts of paulownia leaves, 20-25 parts of lumbricus, 3-5 parts of morus alba, 15-18 parts of carrots and 31-34 parts of kelps. Compared with actual cultivation operation and tests, the special feed additive for cultivating the siniperca chuatsi can be used for obviously reducing the death rate in the cultivating process of the siniperca chuatsi and the growing speed of the siniperca chuatsi is also increased, so that the special feed additive has important meaning to the cultivating industry of the siniperca chuatsi.

Description

technical field [0001] The invention belongs to the field of feed and relates to a special feed additive for mandarin fish breeding. Background technique [0002] mandarin fish ( Siniperca chuatsi Basilewsky ) is a rare freshwater fish native to my country. It has the characteristics of beautiful body, tender meat, delicious taste and rich nutrition. At present, mandarin fish has become a must-have item in most aquatic product markets across the country, and it is also one of the must-have items in the live fish counters of many large supermarkets. volume will gradually increase. The breeding and market demand of mandarin fish has broad development prospects. [0003] At present, the artificial breeding of mandarin fish is mainly fed with compound feed, supplemented by small fish and shrimp. The nutrition of the compound feed is incomplete, the collocation of nutrients is unbalanced, the protein and vitamin content are low, and the palatability is poor, causing the manda...
