Quality traits in aquaculture Aquaculture species are reared for particular traits such as growth rate, survival rate, meat quality, resistance to diseases, age at sexual maturation, fecundity, shell traits like shell size, shell colour, etc. Growth rate – growth rate is normally measured as either body weight or body length. This trait is of great economic importance for all aquaculture species as faster growth rate speeds up the turnover of production.[19] Improved growth rates show that farmed animals utilize their feed more efficiently through a positive correlated response.[18] Survival rate – survival rate may take into account the degrees of resistance to diseases.[18] This may also see the stress response as fish under stress are highly vulnerable to diseases.[19] The stress fish experience could be of biological, chemical or environmental influence. Meat quality – the quality of fish is of great economic importance in the market. Fish quality usually takes into account size, meatiness, and percentage of fat, colour of flesh, taste, shape of the body, ideal oil and omega-3 content.[18][ Read more

Plant breeding Plant breeding has been used for thousands of years, and began with the domestication of wild plants into uniform and predictable agricultural cultigens. High-yielding varieties have been particularly important in agriculture. Selective plant breeding is also used in research to produce transgenic animals that breed "true" (i.e., are homozygous) for artificially inserted or deleted genes.[1 Read more

Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds.[1] Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. Read more

isotope labeling agents Agriculture is the science and art of cultivating plants and livestock.[1] Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Pigs, sheep and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture into the twenty-first.

Politics is the set of activities that are associated with the governance of a country, state or an area. It involves making decisions that apply to groups of members. It refers to achieving and exercising positions of governance—organized control over a human community, particularly a state.The academic study focusing on just politics, which is therefore more targeted than general political science, is sometimes referred to as politology (not to be confused with politicology, a synonym for political science). In modern nation-states, people often form political parties to represent their ideas. Members of a party often agree to take the same position on many issues and agree to support the same changes to law and the same leaders. Read more

The onion, known as the bulb onion or common onion, is not only a key ingredient in many tasty and healthy vegetarian meals but also many traditional medicines. Nine new flavonoids [cepaflavas A, B (5, 6), cepadials A–D (7–9 and 14), and cepabiflas A–C (10–12)] and six known compounds (1–4, 13, 15) were obtained from the outer skins of Allium cepa L. Among them, compounds 5, 6, and 9 might be artificial products formed during extraction and isolation. New compounds were structurally elucidated using various spectroscopy/spectrometry techniques, including NMR and HRMS, and computational methods. T Read more

Most cities and towns everywhere have local business groups that meet on a regular basis. In North America the largest business group is the Chamber of Commerce. The U.S. Chamber of Commerce was formed in 1912 and the Canadian CoC soon afterwards, in 1925. According to the Canadian Chamber of Commerce website, the CoC's primary mandate is to "advocate for public policies that will foster a strong, competitive economic environment that benefits businesses, communities and families".  Read more

Wild harvesting mushrooms can also be a lot of fun, and fairly lucrative, if you know where to go and when, and can find a buyer. Many gourmet restaurants are thrilled to get wild-harvested mushrooms, so it’s worth trying to make these connections. I have done this with both morel’s and hen of the woods (see pictures below). But make sure you know what you’re doing if you’re going to hunt (for more information see below). Also anyone interested in this topic should check out Read more
