Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in an artificial environment. Terrestrial or aquatic plants may grow freely with their roots exposed to the nutritious liquid or the roots may be mechanically supported by an inert medium such as perlite, gravel, or other substrates.
Any worm that lives in a marine environment is considered a water worm. Marine worms are found in several different phyla, including the Platyhelminthes, Nematoda, Annelida, Chaetognatha, Hemichordata, and Phoronida. For a list of marine animals that have been called "sea worms", see sea worm.
Trout is a generic common name for numerous species of carnivorous freshwater ray-finned fishes belonging to the genera Oncorhynchus, Salmo and Salvelinus, all of which are members of the subfamily Salmoninae in the family Salmonidae. The word trout is also used for some similar-shaped but non-salmonid fish, such as the spotted seatrout/speckled trout.
The largemouth bass is a carnivorous freshwater ray-finned fish in the Centrarchidae (sunfish) family, native to the eastern and central United States, southeastern Canada and northern Mexico. It is known by a variety of regional names, such as the widemouth bass, bigmouth bass, black bass, bucketmouth, largie, Potter's fish, Florida bass, Florida largemouth, green bass, bucketmouth bass, green trout, Gilsdorf bass, Oswego bass, LMB, and southern largemouth and northern largemouth.
Vermicompost (vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast. This process is called vermicomposting, with the rearing of worms for this purpose is called vermiculture.
A vending machine is an automated machine that dispenses items such as snacks, beverages, cigarettes, and lottery tickets to consumers after cash, a credit card, or other forms of payment are inserted into the machine or otherwise made. The first modern vending machines were developed in England in the early 1880s and dispensed postcards. Vending machines exist in many countries and, in more recent times, specialized vending machines that provide less common products compared to traditional vending machine items have been created.
Ascariasis is a disease caused by the parasitic roundworm Ascaris lumbricoides. Infections have no symptoms in more than 85% of cases, especially if the number of worms is small. Symptoms increase with the number of worms present and may include shortness of breath and fever in the beginning of the disease. These may be followed by symptoms of abdominal swelling, abdominal pain, and diarrhea. Children are most commonly affected, and in this age group the infection may also cause poor weight gain, malnutrition, and learning problems.
Aquaponics is a food production system that couples aquaculture with hydroponics whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
A ticket machine, also known as a ticket vending machine (TVM), is a vending machine that produces paper or electronic tickets, or recharges a stored-value card or smart card or the user's mobile wallet, typically on a smartphone. For instance, ticket machines dispense train tickets at railway stations, transit tickets at metro stations and tram tickets at some tram stops and in some trams. Token machines may dispense the ticket in the form of a token which has the same function as a paper or electronic ticket. The typical transaction consists of a user using the display interface to select the type and quantity of tickets and then choosing a payment method of either cash, credit/debit card or smartcard. The ticket(s) are then printed on paper and dispensed to the user, or loaded onto the user's smartcard or smartphone.
Georgia is a brand of coffee drinks sold by The Coca-Cola Company. The brand is named after Coca-Cola's home state of Georgia. Launched in 1975, it has since expanded to markets in Singapore, South Korea, India, Bahrain, and the United States of America.
Hymenolepiasis is infestation by one of two species of tapeworm: Hymenolepis nana or H. diminuta. Alternative names are dwarf tapeworm infection and rat tapeworm infection. The disease is a type of helminthiasis which is classified as a neglected tropical disease.
The common bream, also known as the freshwater bream, bream, bronze bream, carp bream or sweaty bream, is a European species of freshwater fish in the family Cyprinidae. It is now considered to be the only species in the genus Abramis.
Saprophages are organisms that obtain nutrients by consuming decomposing dead plant or animal biomass. They are distinguished from detritivores in that saprophages are sessile consumers while detritivores are mobile. Typical saprophagic animals include sedentary polychaetes such as amphitrites and other terebellids.
Live food is living animals used as food for other carnivorous or omnivorous animals kept in captivity; in other words, small preys fed alive to larger predators kept either in a zoo or as a pet.
Soft plastic bait, commonly known as soft lure, soft plastics, plastic bait, worm lure or just worm, is any of a range of elastomer-based fishing lures termed so because of their flexible, flesh-like texture. Soft lures are available in a large range of colours, sizes and particularly shapes, and are typically impaled directly onto a fishing hook like an ordinary bait.
Envipco is an American manufacturer and distributor of reverse vending machines. Envipco's corporate headquarters are located in Naugatuck, Connecticut. Envipco stands for Environmental Products Corporation.
Fishing bait is any luring substance used specifically to attract and catch fish, typically when angling with a hook and line. There are generally two types of baits used in angling: hookbaits, which are directly mounted onto fish hooks and are what the term "fishing bait" typically refers to; and groundbaits, which are scattered separately into the water as an "appetizer" to attract the fish nearer to the hook. Despite the bait's sole importance is to provoke a feeding response out of the target fish, the way how fish react to different baits is quite poorly understood.
Fishing for walleye is a popular sport with anglers. The current IGFA all tackle record is 11.34 kilograms, caught on August 2, 1960 in Old Hickory Lake, Tennessee.
Invasive species of earthworms from the suborder Lumbricina have been expanding their range in North America. Earthworms are considered one of the most abundant macroinvertebrates in the soil of ecosystems in temperate and tropical climates. There are around 3,000 species known worldwide. They are considered keystone species in their native habitats of Asia and Europe because, as detritivores, they alter many different variables of their ecosystem. Their introduction to North America has had marked effects on the nutrient cycles and soil profiles in temperate forests. These earthworms increase the cycling and leaching of nutrients by breaking up decaying organic matter and spreading it into the soil. This thins out the soil rapidly because earthworms do not require a mate to reproduce, allowing them to spread fast. Since plants native to these northern forests are evolutionarily adapted to the presence of thick layers of decaying organic matter, the introduction of worms can lead to a loss of biodiversity as young plants face less nutrient-rich conditions. Some species of trees and other plants may be incapable of surviving such changes in available nutrients. This change in the plant diversity in turn affects other organisms and often leads to increased invasions of other exotic species as well as overall forest decline. They are considered one of the most invasive animals in the Midwestern United States along with feral swine.
Tevnia is a genus of giant tube worm in the family Siboglinidae, with only one species, Tevnia jerichonana, living in a unique deep-sea environment. These deep sea marine species survive in environments like hydrothermal vents. These vents give off gas and toxic chemicals with the addition of having superheated temperatures. The giant tube worm prefers environments such as these despite the harsh temperature and toxic sea water.
