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]
In chronic cases, fin rot, or frayed and ragged fins, can appear. These begin at the base of the dorsal fin on the back of a fish and spread over time, hence the name saddleback disease. [3] Ulcerations on the skin, and subsequent epidermal loss, identifiable as white or cloudy, fungus-like patches – particularly on the gill filaments, may ...
Pseudomonas fluorescens has multiple flagella, an extremely versatile metabolism, and can be found in the soil and in water.It is an obligate aerobe, but certain strains are capable of using nitrate instead of oxygen as a final electron acceptor during cellular respiration.
Like humans and other animals, fish suffer from diseases and parasites.Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth.
Fin Rot is a common bacterial infection affecting the fins of aquarium fish. It is characterized by the fraying, discoloration, and gradual degradation of the fish's fins, giving them a ragged appearance. [8] If left untreated, the condition can progress from the fins to the body, leading to a more severe form known as body rot.
It includes a trophont stage residing in the fish surface (gill epithelia, skin and fin epidermis). This stage is the feeding stage which continuously ingests cellular debris and live host cells in its epidermal location, making the parasite able to grow rapidly over a short time - depending on temperature.

Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere .
