Columnaris disease in young fish is acute and damages the gills, leading to death by respiratory distress. [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]
Fin rot starts at the edge of the fins, and destroys more and more tissue until it reaches the fin base. If it does reach the fin base, the fish will never be able to regenerate the lost tissue. At this point, the disease may begin to attack the fish's body; this is called advanced fin and body rot. Fin rot is common in bettas due to poor water ...
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.
Asian arowanas grow up to 90 cm (35 in) total length. [9] Like all Scleropages, Asian arowanas have long bodies; large, elongated pectoral fins, dorsal and anal fins located far back on the body; and a much larger caudal fin than that of their South American relative, the silver arowana, Osteoglossum bicirrhosum. The mouth is oblique with a ...
The primary causative agents of fin rot are gram-negative bacteria such as Pseudomonas fluorescens and Aeromonas hydrophila. [71] Poor water quality, overcrowding, and stress are significant contributors to the onset and progression of the disease, as they create an environment conducive for bacterial growth and can compromise the fish's immune ...
Japan's Fisheries Agency has proposed a plan to allow catching fin whales in addition to three smaller whale species currently permitted under the country's commercial whaling around its coast ...
Treatment starts with testing the water to ensure cleanliness, then the goldfish should fast for three days if no improvements are made. If the fish still seems ill, then it should be fed low-protein foods and vegetables. [4] Fin Rot is developed from bacteria eating or deteriorating the fins. The disease originates from "poor water quality ...
Japan will add large fin whales to its list of commercial whaling species, government spokesperson Yoshimasa Hayashi said on Thursday, five years after leaving an international body that regulates ...
