It is an erect annual herb with superficial adventitious roots, bulbs composed of a disk like stem ( Abebe D, 2003 ). It has long tradition as medicinal plant, started with a direction of preparing a medicinal remedy written in a cuneiform character in about 3000 BC. Scientific investigations of various garlic preparations began in 1939 ( Weiss RF, 1988 ) The use of higher plants and preparations from them to treat infections is an age-old practice. Interests in plants with antimicrobial properties have come to use again because of emergence of resistance strains against antimicrobials such as penicillin ( Dikasso D, 1999 ). There are a number of studies carried out to assess the value of herbal remedies including garlic preparations for treat of illness. This study will confirm the aqueous extract of Garlic had antib

Aquaculture and microbiological problems

  Aquaculture and microbiological problems in aqua culturing What is Aquaculture? Aquaculture is the  breeding ,  rearing , and  harvesting  of fish, shellfish, algae, and other organisms in all types of water environments . Introduction Aquaculture is the rearing of aquatic species under controlled conditions, and includes the production of fish, shellfish, plants (seaweeds), alligators, amphibians, crocodiles and turtles. The process includes self-contained processes starting with the acquisition of eggs and sperm from dedicated brood stock through to market-sized individuals, such as Atlantic salmon. Origin of Aquaculture Aquaculture may be traced back to common carp ( Cyprinus carpio ) culture in China, which is considered to have been developed during 2000–1000 BC. Fan Lai (a politician turned fish culturist, in ancient China during the 5th century BC) wrote a landmark publication on fish culture in ~500 BC; this was the earliest known monograph on carp culture

He was a leading  ecologist  and among the founders of the modern environmental movement. The First Law of Ecology     Everything Is Connected to Everything Else . There is one ecosphere for all living organisms and what affects one, affects all.  “When we try to pick out anything by itself, we find it hitched to everything else in the universe.”  John Muir The Second Law of Ecology   Everything must go somewhere . There is no “waste” in nature and there is no “away” to which things can be thrown. Any waste produced in one ecological process is recycled in another. A core principle for the Circular Economy. The Third Law of Ecology Nature Knows Best . Humankind has fashioned technology to improve upon nature, but any human change in a natural system is, says Commoner, “likely to be detrimental to that system” And in the context of chemicals of
