Malachite green

Malachite green is an organic compound that is used as a dyestuff and controversially as an antimicrobial in aquaculture. Malachite green is traditionally used as a dye for materials such as silk, leather, and paper. Despite its name the dye is not prepared from the mineral malachite, and the name just comes from the similarity of color.

Fish medicine

Fish medicine is the study and treatment of the diseases of fish. Although some practitioners work primarily with aquarium fish, this field also has important applications to fisheries management. Fish medicine is a relatively recent veterinary specialization; veterinary textbooks in the English language were not published until the early 1990s. The United States does not have an official specialization for fish medicine, worldwide there are several professional organizations for veterinarians interested in fish medicine, such as the World Aquatic Veterinary Medical Association, and the In ...

Melafix

Melafix is an all-natural aquarium antibiotic consisting of an essential oil from a tree in the Melaleuca genus. Contrary to popular opinion it is not made from the common Tea tree, Melaleuca alternifolia, but from Melaleuca leucadendra, also known as the Cajeput Tree. This is confirmed by the manufacturers Safety Data Sheet. It is a wide-range antibiotic product, and thus is effective for a wide variety of mild gram positive bacterial infections, such as fin rot. However, it is generally ineffective against aquatic parasites and is typically used for treating the wounds caused by them in ...

Olfactory toxicity in fish

The olfactory system is the system related to the sense of smell. Many fish activities are dependent on olfaction, such as: mating, discriminating kin, avoiding predators, locating food, contaminant avoidance, imprinting and homing. These activities are referred to as" olfactory-mediated.” Impairment of the olfactory system threatens survival and has been used as an ecologically relevant sub-lethal toxicological endpoint for fish within studies. Olfactory information is received by sensory neurons, like the olfactory nerve, that are in a covered cavity separated from the aquatic environmen ...

Pain in fish

Whether fish feel pain similar to humans or differently is a contentious issue. Pain is a complex mental state, with a distinct perceptual quality but also associated with suffering, which is an emotional state. Because of this complexity, the presence of pain in an animal, or another human for that matter, cannot be determined unambiguously using observational methods, but the conclusion that animals experience pain is often inferred on the basis of likely presence of phenomenal consciousness which is deduced from comparative brain physiology as well as physical and behavioural reactions. ...
