Catfish are easy to farm in warm climates, leading to inexpensive and safe food at local grocers. Catfish raised in inland tanks or channels are considered safe for the environment, since their waste and disease should be contained and not spread to the wild.

Aquaculture in Australia is the country`s fastest growing primary industry, accounting for 34% of the total gross value of production of seafood.Mud crabs have been cultivated in Australia for many years, sometimes leading to over-exploitation. Traditionally, this aquaculture was limited to pearls, but since the early 1970s, there has been significant research and commercial development of other forms of aquaculture, including finfish, crustaceans, and molluscs.

High Quality Content by WIKIPEDIA articles! Giant kelp, Macrocystis pyrifera, has been utilized for many years as a food source; it contains many compounds such as iodine, potassium, other minerals vitamins and carbohydrates and thus has also been used as a dietary supplement. In the beginning of the 20th century California kelp beds were harvested as a source for potash. With commercial interest increasing significantly during the 1970s and the 1980s this was primarily due to the production of alginates, and also for biomass production for animal feed due to the energy crisis during that period. However commercial production for M.pyrifera never became a reality. With the end of the energy crisis and the decline in prices of alginates,...

High Quality Content by WIKIPEDIA articles! AquAdvantage salmon is the trade name for a genetically modified Atlantic salmon developed by AquaBounty Technologies. The AquAdvantage salmon has been modified by the addition of a growth hormone regulating gene from a Pacific Chinook salmon and a promoter gene from an ocean pout to the Atlantic`s 40,000 genes. These genes enable it to grow year-round instead of only during Spring and Summer. The purpose of the modifications is to increase the speed at which the fish grows, without affecting its ultimate size or other qualities. The fish grows to market size in 16 to 18 months rather than three years. The latter figure refers to varieties whose growth rate has already been improved by 2:1 as a...

Aquascaping is the craft of arranging aquatic plants, as well as rocks, stones, cavework, or driftwood, in an aesthetically pleasing manner within an aquarium—in effect, gardening under water. Aquascape designs include a number of distinct styles, including the colorful Dutch style and the evocative nature style. Typically, an aquascape houses fish as well as plants, although it is possible to create an aquascape with plants only, or even with rockwork or other hardscape and no plants. Although the primary aim of aquascaping is to create an artful underwater landscape, the technical aspects of aquatic plant maintenance must also taken into consideration. Many factors must be balanced in the closed system of an aquarium tank to ensure...

High Quality Content by WIKIPEDIA articles! The aquatic ape hypothesis (AAH) is an alternative explanation of human evolution which theorizes that the common ancestors of modern humans spent a period of time adapting to life in a partially-aquatic environment. The theory is based on differences between humans and great apes, and apparent similarities between humans and some aquatic mammals. First proposed in 1942 and expanded in 1960, its greatest proponent has been the writer Elaine Morgan, who has spent more than forty years discussing the AAH. While it is uncontroversial that both H. neanderthalensis and early H. sapiens were better suited to aquatic environments than other great apes, and there have been theories suggesting...

Swimming has evolved a number of times in a range of organisms ranging from arthropods to fish to molluscs. All cephalopods can move by jet propulsion, but this is a very energy-consuming way to travel compared to the tail propulsion used by fish. The relative efficiency of jet propulsion decreases further as animal size increases. Since the Paleozoic, as competition with fish produced an environment where efficient motion was crucial to survival, jet propulsion has taken a back role, with fins and tentacles used to maintain a steady velocity....

An aquatic animal is an animal, either vertebrate or invertebrate, which lives in water for most or all of its life. It may breathe air or extract its oxygen from that dissolved in water through specialised organs called gills, or directly through its skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land). Animals that move readily from water to land and vice versa are often referred to as amphibious. The term aquatic can in theory be applied to animals that live in either freshwater or saltwater. However, the adjective marine is most commonly used for animals that live in saltwater, i.e. in oceans, seas, etc. Aquatic animals (especially freshwater animals) are often of...

High Quality Content by WIKIPEDIA articles! Aquatic predation presents a special difficulty as compared to predation on land, because the density of water is about the same as that of the prey, so that the prey tends to be pushed away. This problem was first identified by R.N. Alexander. As a result, under water predators, especially bony fish, have evolved a number of specialized feeding mechanisms, known as filter feeding, ram feeding, suction feeding, protrusion, and pivot feeding. Most under water predators combine more than one of these basic principles. For example a typical generalized predator, such as the cod, combines suction with some amount of protrusion and pivot feeding. Suction feeding is a method of ingesting a prey item...

They feed in the same ways as other insects. Some diving insects, such as predatory diving beetles, can hunt for food underwater where land-living insects cannot compete. One problem that aquatic insects must overcome is how to get oxygen while they are under water. All animals require a source of oxygen to live. Insects draw air into their bodies through spiracles, holes found along the sides of the abdomen. These spiracles are connected to tracheal tubes where oxygen can be absorbed. All aquatic insects have become adapted to their environment...

The AraAppaloosa, also known as the Araloosa, Arappaloosa and the Ara-Appaloosa, is a horse breed that is a cross between an Arabian horse and an Appaloosa, combining the refined phenotype of the Arabian with the leopard-spotted coloring of the Appaloosa. As both breeds are noted for endurance and intelligence, the resulting cross is usually able to excel at endurance riding as well as other disciplines performed by either breed, including ranch work, and a variety of horse show disciplines. An AraAppaloosa with one purebred Arabian parent may be registered as a half-Arabian with the Arabian Horse Association, and because the Appaloosa breed still has an open stud book to horses of Arabian breeding, many Arappaloosas can also be...

High Quality Content by WIKIPEDIA articles! The Arabian Grosbeak or Arabian Golden-winged Grosbeak (Rhynchostruthus percivali) is a finch found in Saudi Arabia, Oman and Yemen. It is included as a subspecies in R. socotranus by some authorities, but in recent times the three golden-winged grosbeak populations are usually considered distinct species. The true finches are passerine birds in the family Fringillidae. They are predominantly seed-eating songbirds. Most are native to Southern Hemisphere, but one subfamily is endemic to the Neotropics, one to the Hawaiian Islands, and one subfamily – monotypic at genus level – is found only in the Palaearctic. The scientific name Fringillidae comes from the Latin word fringilla for the...

Arachnology is the scientific study of spiders and related animals such as scorpions, pseudoscorpions, harvestmen, collectively called arachnids. However, the study of ticks and mites is sometimes not included in arachnology, but is called Acarology. Those who study spiders and other arachnids are arachnologists. The word arachnology derives from Greek , arachne, "spider"; and - , -logia. Arachnologists are primarily responsible for classifying arachnids and studying aspects of their biology. In the popular imagination they are sometimes referred to as 'spider experts'. Disciplines within arachnology include...
