Описание: Aquaculture is the practice of cultivating aquatic animals and plants in managed aquatic environments. Aquaculture in salt-water or marine environments is called mariculture. Fish culture, or pisciculture, refers to the husbandry of finfish. The most popular aquaculture species are finfish grown in fresh waters, accounting for over 40 percent of total aquaculture production. Aquaculture has a long history, but for much of the world it remains somewhat of a novelty, being practiced less than agriculture or capture fisheries. During the last 30 years of the twentieth century, aquaculture grew at an average annual rate of 10 percent, and emerged as the only growth sector of the fisheries industry. At the beginning of the twenty-first century, aquacultures share of total fish production worldwide was 25 percent, and that proportion is projected to increase. Even though the production of fish from capture fisheries has not substantially increased over the past decade, capture fisheries nevertheless account for a far greater percentage than aquaculture. Aquaculture is practiced for a number of reasons, chief among them being food production and income generation. Most fresh-water aquaculture production (over 70 percent) comes from low-income, food-deficit countries. Even in the poorest countries, fish farming is seldom solely a subsistence activity. So while farmers may consume some of their product, typically fish are sold, thereby enabling farmers to earn income to purchase other goods and services. Aquaculture has two types, freshwater aquaculture and salt-water aquaculture. With the ever increasing demand of fish and increased fish catching activities, sea is facing shortage of fish and cannot fulfil this much demand. Freshwater aquaculture has also improved economies of many areas by providing new job opportunities. The fish produced there is mostly used by industries for processing which is then made available as canned food item. This is the ultimate guide to freshwater aquaculture, an essential resource for both professional aquaculturists and backyard fish growers.

In this magical middle-grade debut novel from Adrianna Cuevas, The Total Eclipse of Nestor Lopez, a Cuban American boy must use his secret ability to communicate with animals to save the inhabitants of his town when they are threatened by a tule vieja, a witch that transforms into animals.
All Nestor Lopez wants is to live in one place for more than a few months and have dinner with his dad. When he and his mother move to a new town to live with his grandmother after his dad's latest deployment, Nestor plans to lay low. He definitely doesn't want to anyone find out his deepest secret: that he can talk to animals. But when the animals in his new town start disappearing, Nestor's grandmother becomes the prime suspect after she is spotted in the woods where they were last seen. As Nestor investigates the source of the disappearances, he learns that they are being seized by a tule vieja--a witch who can absorb an animal's powers by biting it during a solar eclipse. And the next eclipse is just around the corner... Now it's up to Nestor's extraordinary ability and his new friends to catch the tule vieja--and save a place he might just call home.

Описание: In African Mexicans and the Discourse on Modern Nation, author Marco Polo Hernandez Cuevas explores how the Africaness of Mexican mestizaje was erased from the national memory and identity and how national African ethnic contributions were plagiarized by the criollo elite in modern Mexico.
Aliens is a highly debated topic, sometimes in favour others against it. Once again, we introduce more than fifty bioenergemal communications (BELCs) that for over the years we have presumably had, amongst others, with the bioenergeme of Khriannia, an extraterrestrial woman, occasionally with some of her close relatives and acquaintances, too, and finally with the bioenergeme of Bhrikiam, an extraterrestrial man. Both said to come from a planet named Agram, located in Andromeda constellation of the Milky Way. Besides, we have had BELCs with several alien civilizations. This rich bioinformation is exclusive of this book.

Описание: Fruit and vegetable production and consumption globally have shown a marked upward trend over the past several years. Rising consumer demand in the world has come with greater awareness of food safety issues and increased need for convenience and quality. The fresh-cut produce sector has responded to these demands, and is currently at different stages of development across the globe. Assuring the safety and quality of fresh-cut produce necessitates the selection of high quality horticultural produce for processing, and the implementation of good practice during processing operations in order to maintain produce quality and assure safety of the final product. Todays society is characterised by an increasing health consciousness and growing interest in the role of food for maintaining and improving human well-being and consumer health. In addition to their nutritional and sensory properties, foods are currently recognised as active and protective agents. In the last years, their consumption has continued to grow rapidly linked to the increased public awareness of their health benefits. On the other hand, this new trend, has also hiked the chances of outbreaks of food poisoning and food infection related to consumption of fresh fruit and uncooked salad. The book highlights the use of emerging technologies to ensure microbiological stability and quality of fresh-cut fruits and vegetables. In particular, the aim of the content is to give an insight into the current knowledge on the technologies mostly suggested to ensure microbiological stability and quality of fresh-cut fruits and vegetables, in order to marketing and supply information about this subject which remains still a major challenge for the food industry. The book provides helpful guidelines to the industry for minimizing deterioration, keeping the overall quality, and lengthening the shelf life. Technology, physiology, quality, and safety of fresh-cut fruits and vegetables are emphasised. It is well known that processing of fruit promotes a faster physiological deterioration, biochemical changes and microbial degradation of the products which may result in degradation of its colour, texture and flavour, even when only slight processing operations are used. Prior to being packaged for consumption, minimally processed fruits are subjected to one or more mild unit operations, which include washing, sanitising, peeling, cutting and/or slicing, dicing, shredding, etc. A special attention is necessary for mechanical operations considered very critical to delimit the shelf life of fresh-cut fruit commodities, causing the rupture of many cells and the liberation of intracellular products (such as oxidising enzymes); at the same time, the surface of produce is exposed to air and to possible contamination with bacteria, yeasts and moulds. It is important to underline that cutting increases the area of injured tissues favoring elevated respiration, promoting further rapid deterioration and microbial proliferation.
