Description

Loach efficient fishing device based on 4Ps marketing strategy

Technical Field

The invention relates to a 4Ps marketing strategy-based loach efficient catching device, and belongs to the technical field of marketing strategy application.

Background

The 4Ps marketing strategy, which was generated in the united states in the 60's of the 20 th century, emerged with the introduction of marketing portfolio theory. In 1953, Neil Borden created the term "Marketing mix" (Marketing mix) in the vocational speech of the American society for Marketing and Marketing, which means that market demand is more or less affected to some extent by so-called "Marketing variables" or "Marketing factors". In order to seek certain market reaction, enterprises need to effectively combine the elements so as to meet market demands and obtain maximum profits. Marketing combinations actually several tens of elements proposed by borden originally included 12 elements, which were generally summarized in 1960 in its Basic Marketing book as category 4: product (Product), Price (Price), channel (Place), Promotion (movement), i.e. famous 4 Ps. In 1967, philips kettler in his best-selling book "marketing management: analysis, planning and control the first edition further confirms the marketing combination method taking 4Ps as the core, namely: product: the development function is focused, the product is required to have a unique selling point, and the functional appeal of the product is put to the first place. Price (Price): according to different market positions, different price strategies are made, the pricing basis of the product is the brand strategy of an enterprise, and the gold content of the brand is emphasized. Distribution (Place): the enterprise does not directly face the consumer, but focuses on the establishment of a network of development and sales for the distributor, and the enterprise contacts the consumer through the distributor. Promotion (Promotion): enterprises pay attention to changes in sales behavior to stimulate consumers, to promote growth in consumption with short-term behaviors such as concessions, buy-and-send, marketing site atmosphere, and the like, to attract consumers of other brands, or to lead to advanced consumption to promote growth in sales. The combination of marketing factors is required and aimed to best meet the consumer needs of the target market with the most appropriate product, at the most appropriate price, with the most appropriate sales promotion method and sales network, to achieve the best reputation and economic benefits. Loach belongs to the family of loach, commonly called loach, is small in shape and slender, and is only three inches or four inches; the shape of the body is round, the body is short, the small flakes are arranged under the skin, the color is dark, the body is fully stained with self mucus, and therefore, the body is greasy and cannot be held; the front section is slightly cylindrical, the rear part is flat, the abdomen is round, the head is small, the mouth is small, the lower part is in a horseshoe shape; small eyes without down-prick; 5 pairs of the scaly hairs are tiny and round, and are buried under the skin; the back and two sides of the body are gray black, the whole body has a plurality of small black spots, the head and each fin also have a plurality of black spots, the spots on the dorsal fin and the tail fin membrane are arranged in rows, the base of the tail handle has a obvious black spot, and other fins are grey white. Loaches are widely distributed in china, japan, korea, russia, india, etc. along the coast of asia. Collected all the year round, and most in summer, and the loaches can be used fresh or dried after being captured. Loaches live in lakes and ponds, are small-sized bottom fishes, live in static or slow-flowing water at silt bottom, have strong adaptability and can live in an environment rich in humus. When the water is lack of oxygen, intestinal respiration can be carried out, and the water can be buried into mud for latency after being dried. All kinds of small animals are taken as food. The loach can breathe by using gills and skins and also has a special intestinal respiration function; when the weather is sultry or the mud and the humus at the bottom of the pool are rotten to cause severe oxygen deficiency, the loach can jump out of the water surface or vertically rise to the water surface, directly swallow air by mouth and assist respiration by intestinal wall, and when the loach rotates to slowly dive, the waste gas is discharged from the anus. At each time, the loaches in the whole water body rise to the water surface to suck air, which is a trend, so that western europe has a name of climate fish. In winter, the water body is dry, loaches enter soil, the skin is not dry by virtue of a small amount of water, and the life is maintained by intestinal respiration. In the next year, the water rises and moves outside. Loach muscle contains aspartate aminotransferase (aspartate aminotransferase). Every 100g of meat contains 83g of water, 9.6g of protein, 3.7g of fat, 2.5g of carbohydrate, 1.2g of ash, 28mg of calcium, 72mg of phosphorus and 0.9mg of iron. The fat contains docosahexaenoic acid (docosaxenoic acid) and octadecenoic acid (calendic acid). The tissues contain amines (spermine), spermidine (spermindin), putrescine (putrescine) and cadaverine (cadeverine). The dried loach skin contains gamma-butyrolactone (gamma-butyrolactone). Loaches contain a variety of enzymes: proteases (proteases), phenotyp-6-phosphogluconate deoxyases (phenotyp of 6-phosphogluconate dehydrogenase), phosphoglucomutase (phosphoglucomutase), lactate dehydrogenases (1act dehydrogenase); also contains cytosine (cytosine), xanthine (xanthine), adenine (adenine), guanine nucleoside (guanosine), guanine (guananine), pyrimidine (pyrimidine), purine bases (purine bases), nucleoside (nucleotide), nucleotide 3 (nucleotide), adenosine (adenylic acid), guanylic acid (guanylic acid), uracil nucleotides (uridylic acid), deoxyguanylic acid (deoxyguanylic acid); in addition, it contains F-type prostaglandins (F-type prostagladins), muscle proteins (muscle proteins), 4-2, 4, 6-trichlorophenoxy-N-acetanilide [4-2, 4, 6, -trichlorophenoxy-cyanidide ] and 4-2, 4, 6-trichlorophenoxy formanilide [4, 2, 4, 6-trichlorophenoxy formanilide ], vitamins (vitamin) A, B1.B2, and nicotinic acid (nicotinic acid). Spermidine is the main component of sperm, and the modern medicine proves that the spermidine can promote the number and the development of human embryonic cells, delay and reverse aging, and increase the skin elasticity and the moisture degree by the U.S. patent number: 10/556,411, and can bind DNA. Docosahexaenoic acid and octadecenoic acid, which are important components of cephalin and retina, are commonly called DHA. Phosphoglyceromutase in loaches is unique to human beings, can improve dominant inheritance of chromosomes, and is a preferred food for prenatal and postnatal care. The phosphoglucose dehydrogenase stimulates the generation of alcohol oxidoreductase in human bodies, and is a necessary food for people who drink a large amount of alcohol for a long time to eat. Loach also contains abundant nucleosides, which are the main components of various vaccines and can improve the antiviral ability of the body. Phosphoglucomutase has good adjuvant treatment effect on hepatitis and cancer. In the aspect of medicine, the loach contains high-quality protein, fat, vitamin A, vitamin B1, nicotinic acid, iron, phosphorus, calcium and the like, has sweet taste and mild nature, has the effects of tonifying middle-jiao and Qi, nourishing kidney and producing sperm, has better effect on regulating sexual function, and can nourish and strengthen the body of adult men after eating the loach frequently. The loach fish is sweet and neutral in nature, and has the effects of warming the middle-jiao and replenishing qi, clearing and promoting urination, and detoxifying and recovering hemorrhoids. The loach has tender meat and high nutritive value, and its hydrostomia has antibacterial and anti-inflammatory effects. Can be used for treating jaundice due to damp-heat pathogen, dysuria, night sweat, etc. The loach has delicious taste and rich nutrition, has higher protein content and lower fat content, can reduce blood fat and blood pressure, is a delicious dish and a popular food, and is really good at the reputation of "supernatural turtledoves, underground loaches" and "ginseng in water". Has good taste, nourishing effect, easy availability, and low cost. The edible part of the loach accounts for about 80 percent of the whole fish body and is higher than that of common freshwater fish. The loach meat per 100g is determined to contain 22.6 g of protein, 2.9 g of fat, 2.5g of carbohydrate, 1.6 g of ash, 51 mg of calcium, 154 mg of phosphorus, 3 mg of iron, 0.08 mg of thioflavin, 0.16 mg of riboflavin, 5 mg of nicotinic acid and various vitamins, wherein the vitamins comprise 70 mg of vitamin A, 130 mg of vitamin B and 2440 mg of vitamin B and higher unsaturated fatty acid. Loach food with low fat content, less cholesterol, high protein and low fat contains unsaturated fatty acid similar to penaenoic acid, is beneficial to resisting vascular aging, and is beneficial to the elderly and cardiovascular patients. Loach is sweet in taste and neutral in nature, and has effects of invigorating spleen, liver and kidney, and invigorating spleen and kidney; diuresis; and (5) detoxifying. Diarrhea and dysentery due to spleen deficiency; thirst due to febrile disease; quenching thirst; night sweat and edema of children; difficulty in urination; sexual intercourse is not raised; viral hepatitis; hemorrhoids; furuncle; the skin is itchy. Has effects in invigorating spleen, replenishing qi, eliminating dampness, eliminating jaundice, invigorating kidney, tonifying yang, eliminating dampness, relieving diarrhea, warming spleen and stomach, treating hemorrhoid, and relieving sweating due to deficiency. Loach contains various nutrients, proteins, saccharides, minerals (calcium, phosphorus and iron), vitamins (VB, VA and VC), has higher fat content and less cholesterol than common fishes and shrimps, contains unsaturated fat containing the C + -C-pentenoic acid, is cool in nature and is best to eat in summer (centuries of hundredfold). As can be seen from the above, the loaches have rich nutritional values and higher medicinal values, but the loaches are not easy to capture due to the slippery bodies and generally live on the bottom layer of a water body or even in mud, and the efficiency of a common fishing device is extremely low when the loaches are caught, so that how to catch the loaches with time, labor and efficiency becomes a great problem which needs to be solved urgently, so that the loaches high-efficiency catching device based on the 4Ps market marketing strategy utilizes the 4Ps market marketing strategy principle, particularly the Promotion (Promotion) theory, starts from the characteristics of the loaches, the living environment, the living habits and the like, finds out that the loaches almost vertically swim in the water body after long-time analysis and indoor experiments, particularly, the loaches quickly vertically swim to the water bottom once catching food, and prepares granular loaches which can be suspended on the water surface for a short time according to the living habits of the loaches, after the loaches are scattered on the water surface, the loaches can swim to the water surface from one meter deep underwater quickly for eating less than half a minute, and the invention provides the efficient loach catching device based on the 4Ps marketing strategy.
