Global warming has caused widespread concern around the world. The resulting changes in seawater temperature will seriously affect the migration of marine life, and as a result, some small fishing companies will have economic problems. We are honored to be hired as a consultant to analyze this and provide a feasible solution. We studied herring and mackerel in areas near Scotland. Firstly, we looked at the location information of the two types of fish school activity from 1970 to 2020, integrated them, and used the time series model and regression analysis model to predict the area and location of possible fish school activity in the next 50 years. The possible range of movement of the group, which helps the company to carry out timely stopping loss of the current fishing strategy and controlling the future economic regulation. In our prediction model, changes in sea surface temperature have a large impact on the migration behavior of fish schools. In order to prevent the timely fishing due to the influence of temperature, we give the best case, worst case, and most likely case after model prediction, and visualize the data by sorting, analyzing, and calculating. The process is more intuitive. Our forecasting model is affected by many factors, which will affect the economic benefits of the company. On the one hand, if changes are made to fishing vessels to keep the fish fresh and of high quality without land support, the cost in this case is too high; but on the other hand, if we transfer the company appropriate migration will not only allow the company to reduce costs, but also promote the exchange of regional cultures and jointly benefit. For the sake of climate change and economic benefits, we have given this plan. What is slightly inadequate is that the movement process of the animal group we considered is actually continuously changing in two-dimensional space and time. The process of establishing the model in three-dimensional space is not considered in the article. But the practicability and openness of the model are also its biggest advantages, and the sensitivity analysis in the process also makes the model more rigorous.

According to the American Heart Association, “between 2013 and 2016, 121.5 million American adults had some form of cardiovascular disease.”[1] One of the major factors is that doctors may misdiagnose the patients with heart attack and fail to prevent the progressive illness from worsening in the early stage. In this paper, we construct and evaluate an efficient artificial neural network model for analyzing patients’ feature data and predicting the probability of a patient to get a heart attack. With the help of our heart attack prediction model, doctors are able to discover the heart attack early. They can also prescribe medicine for the heart attack patients accurately with the aid of the feature analyzation function of our model. Our heart attack prediction model reaches a high accuracy of 88.51%, which is better than other models.

Over the past 20 years, the way North Atlantic mackerel and herring migrate has changed dramatically. In the 1980s, the migration occurred in the late summer and autumn. Now, the start of the migration is lagging, and their migration routes move further offshore. Firstly, we establish a support vector machine (SVM) model to predict the temperature of a single geographic coordinate point, and then applied it to the whole North Atlantic Ocean. After predicting the sea surface temperatures in the next 50 years, we conduct cluster analysis using ARCGIS, the geographic information analysis tool, to optimize our SVM model. We find that 10 isotherm gradually move northward in the next 50 years, specifically, the habitat of the two fish species will move 2.5◦northward in the future, further away from the mainland. Secondly, we design an operation evaluation model for a small fisheries company based on previous forecast, and assume the best scenario, that is, the rate of global warming to maintain the status QUO, and the worst scenario, 1.5 times faster global warming speed. Our model shows that in the best case, it is unprofitable for the company continuously go fishing after 45 years, and in the worst case, only 5 years. Finally, given that fishing places might move to another country, and give constructive operation suggestions like fishing by time, by categories and by quota.

Peppermint essential oil is widely used in food industry, but it is easy to be oxidized. In order to improve its oxidation stability, the peppermint essential oil microcapsule was prepared by single factor experiment and response surface optimization experiment in the paper. The effect of core wall ratio, pH value of complex coagulation and agitation speed on the embedding rate of peppermint essential oil microcapsules was studied respectively. The optimum experimental conditions were obtained as follows: core wall ratio, 1.9:1; pH value of complex condensation, 4.0; and the optimal agitation speed, 400r/min. The maximum embedding rate of peppermint essential oil microcapsules was 89.67%. POV value showed that the oxidative stability of peppermint essential oil microcapsules was significantly higher than peppermint essential oil.

Organic tea refers to the tea products and reprocessed products that produce fresh leaf raw materials according to the organic agricultural production system and method in the production area without any pollution source, and are not polluted by any chemicals (synthetic fertilizer, pesticide, growth regulator, etc.) in the process of processing, packaging, storage and transportation, and reviewed and certified by the organic tea certification authority. But it's just tea green. The quality of organic tea stir-fried depends on the climate, altitude, craftsman's skills, and other factors, which are not quantifiable, and the cost is quite high. Organic tea is a kind of pollution-free healthy drink. It adapts to people's increasing health care awareness, has a great potential market, can obtain higher economic benefits, is conducive to tea export, and conforms to the basic national policy of national environmental protection. This paper will mainly focus on the current situation of organic tea planting, point out the planting elements of organic tea, and finally discuss the high-yield cultivation technology of high-quality organic tea. 1. Current situation of organic tea planting Organic tea is a kind of green, environmental protection tea, which conforms to the International Federation of Organic Agricultural Movements (IFOAM) standard. It is a kind of tea produced and processed based on the organic agricultural production method, without using any synthetic food additives, pesticides, fertilizers, etc. Organic tea is grown in the most natural state on the land not polluted by pesticides and chemical fertilizers. At the same time, synthetic compounds, chemical fertilizers, and transgenic technology are eliminated during the cultivation period, and no external chemical components are added during the processing of the assembly line. From the processing, production, packaging assembly line production are strictly abide by the specific organic principles. The organic certification of international standards needs to be reviewed annually by a third-party organization from cultivation, processing, production to tea sales. At present, China has established an organic tea production base of about 400 Hm2, with an annual organic tea production of about 500 tons. In China, green tea is the main organic tea, while a small amount of Oolong tea, black tea, etc. But at present, the amino acid content of green tea in China is generally only 2% 7%, the average content of flat tea in Inner Mongolia of Sichuan is 4.8%, the average content of other flat tea is 3.8%, and the "Emei organic tea" is as high as 24.8%.

Fusion enzyme refers to a comprehensive enzyme binding body composed of two or more independent enzymes or domains. It is mainly obtained through the connection of two or more enzymes, which largely retains the function of several domains and is an efficient protein binding body. Recently, with the development of fusion protein technology, the research on the function of fusion enzyme has become a hot spot. Scientists believe that there is a need for the natural evolution of fusion proteins with linkers. In the process of building fusion enzymes, the introduction of linkers can avoid the interference of different domains in the process of protein folding and catalysis, so as to achieve the efficient expression of fusion enzyme.

as a new breed of freshwater culture in China, Murray cod (Macculochella peelii) has attracted much attention. In order to improve the culture benefit, This Article is concentrated on the artificial breeding and fry rearing techniques of Murray cod, including the selection and culture of parent fish, artificial inducing, insemination, hatching, the feeding start time for the fry, food switching, domestication and fish seed culture. This is a reference for the majority of breeding workers. Murray cod is endemic to the Murray-Darling River System, and it tops the four economic fishes in Australia and it is one of the largest freshwater fish in the world. The meat of Macculochella peelii is tender, delicious and thick, and there are few fish bones between muscles. It also contains 4 kinds of amino acids, EPA, DHA and other nutrients. It is high in protein and low in fat, so it is popular among the people. However, due to overfishing, environmental pollution and destruction of spawning grounds, its resource is decreasing day by day. Australia calls it the national treasure fish. Macculochella peelii has the characteristics of fast growth, strong adaptability to environment, high fecundity and survival rate, great disease-resistant ability, easy domestication and high conversion rate of artificial compound feed, so it is suitable for intensive culture in different culture areas [1]. In 1999, it was first introduced to Taiwan from Australia, and in 2001, it was introduced to the mainland of China [2]. At present, as a new breed of freshwater culture in China, the fish has attracted much attention and has great prospects for development. There are many related researches on Macculochella peelii[3-9]. This paper mainly introduces the industrialized artificial breeding technology of Macculochella peelii in China. 1. Artificial breeding 1.1 Selection and culture of parent fish The sexual maturity time of Macculochella peelii is 3-5 years old, and generally, more than 70% of the 4-year-old fishes are mature, the spawning is one batch a year, and the suitable water temperature is 16-20°C. Through the study, we found that under the same conditions, the breeding effect of the parent fish over the age of 6 was better than that of the parent fish at the younger age. We should choose the healthy fish without disease or injury and the body color should be normal. The weight of male is 4~10kg, the weight of female is 5~10 kg, and the ratio of male to female is 1~2:1. The selection of parent fish usually starts in autumn, and it needs about half a year of artificial intensive culture. We need to provide sufficient high protein feed, adjust the fat ratio, add vitamin C, vitamin E, n-3 HUFA and liver-protection products. The nutritional requirements of the parent fish vary with the water temperature. In autumn (September to November), when the water temperature is suitable, the protein required for nutrition is ≧45% and the fat required for nutrition is ≧15%; in winte
