A brief about Vibriosis
Vibriosis is one of the most prevalent aquatic diseases generally caused by gram-negative, facultative anaerobic rod tank bacteria such as Vibrio anguillarum from the Vibrio genus family when the fish’s immune system is low due to stress or any deficiency.
There are numerous strains of Vibrio present in the aquatic terrain at all times. Although they’re more common in marine systems, there are species that can infect freshwater fish and can infect humans, occasionally with really serious consequences.
Species affected: Salmonidae and Perciformes || Occurrence: Usually During Late Summer

Vibrio anguillarum belongs to one of the halophilic groups of Vibrios and survives at different salinities. it is able to survive in sea water for more than 50 months. More than twenty different serovars of V. anguillarum (designated 01 to 023) have been described (Pedersen et al., 1999). Serovars 01 and 02 occur world-wide and are those most often found in connection with diseases in fish particularly in salmonids and species of cod fish.
Symptoms
Red spots on body
Inflammation
Anorexia
Pale gills
Exophthalmia
Sudden death
In a suspected vibriosis outbreak, your veterinarian will collect the deceased fish or a fish close to death to be submitted to a specific laboratory. The laboratory will perform bacterial culture and antibiotic sensitivity testing to identify the prominent bacteria present and which antibiotics it’s highly susceptible to. There are known bacterial resistance to antibiotics, so the culture and perceptivity testing are critical.
Prevention
The best prevention for vibriosis is to identify and correct any implicit stressors in your aquarium. This may include Quarantining all new live additions for at least five weeks (includes plants, invertebrates and live rock) better preventive maintenance, feeding a more enhanced and balanced diet enriched with proper supplements, more balanced water conditions, or/and removing aggressive fish.
A low-stress and healthy environment is highly critical to prevent vibriosis outbreak. Generally available OTA antibiotics are not effective against vibriosis and only veterinarian specified treatment should be applied.
NB Vibrisol
Natural antibacterial aquatic feed supplement specially active against Vibrio species
A Unique blend of scientifically proven non-pathogenic probiotic strains of Bacillus subtilis, Bacillus polymyxa, Bacillus licheniformis and selected herbal extracts.
- NB Vibrisol added to cultured ponds in adequate dosages, establishes itself in the pond, and suppresses the growth of harmful bacteria such as Vibrio sp. And inhibits their growth by producing certain vibriocidal substances.
- It also selectively kills harmful organisms.
- High enzymatic activities remove the organic load caused by excess feed, fecal matter, and algae.
