Fin rot is the phenomenon where the fins of a fish gradually decay and are eventually destroyed. Typically, fin rot is either a symptom of a disease, oftentimes a bacterial or fungal infection, but it can also sometimes be a disease by itself. Fin rot is most often observed in aquaria and aquaculture, but can also occur in natural populations. [1]
It attacks the feather follicles and the beak and claw matrices of the bird, causing progressive feather, claw and beak malformation and necrosis. In later stages of the disease, feather shaft constriction occurs, hampering development until eventually all feather growth stops. It occurs in an acutely fatal form and a chronic form.
Myxobolus cerebralis triactinomyxon Henneguya zschokkei in salmon beard. Diseases can have a variety of causes, including bacterial infections from an external source such as Pseudomonas fluorescens (causing fin rot and fish dropsy), fungal infections (Saprolegnia), mould infections (Oomycete and Saprolegnia), parasitic disorders (Gyrodactylus salaris, Ichthyophthirius multifiliis ...
In chronic cases, fin rot, or frayed and ragged fins, can appear. Lesions begin at the base of the dorsal fin on the back of a fish and spread over time, hence the name saddleback disease. Ulcerations on the skin, and subsequent epidermal loss, identifiable as white or cloudy, fungus-like patches – particularly on the gill filaments, may appear.
These pathogens cause an ulcerative disease known as tenacibaculosis. [5] Characteristics of tenacibaculosis include lesions on the body, necrosis, frayed fin, tail rot, eroded mouth, and sometimes necrosis on the gills and eyes. [5]
The rare find hasn’t been seen on a Cape Town beach in years.
Fins may appear dark, torn, split, ragged, frayed and may even be lost completely. [8] Symptoms begin with tissue erosion, especially on the caudal fin . Other symptoms include the skin of the jaw "ulcerations", [ 7 ] pale in color gills, increased mucus production, blindness, inflammation of the gastrointestinal system, and behavioral issues ...
Peacock tail feather. The conservation and restoration of feathers is the practice of maintaining and preserving feathers or featherwork objects, and requires knowledge of feather anatomy, properties, specialized care procedures, and environmental influences. This practice may be approached through preventive and/or interventive techniques.
