Plant essential oil-based antimicrobial fish filming compositions and methods of use
View Patent ↗Novel plant essential oil-based antimicrobial filming compositions that are useful in protecting, repairing and strengthening the natural slime coat found on fish are disclosed, which compositions are comprised of a mixture of plant essential oils having antimicrobial properties, filming agents, and surfactants.
1. A method for reducing the incidence of microbial infections in fish, the method comprising dispensing an antimicrobial composition into an aquatic environment, the composition comprising between about 0.2% and about 1.6% (% w/w) of at least one plant essential oil, between about 0.1% and about 0.6% (% w/w) of at least one filming agent, between about 3% and about 5% (% w/w) of a plasticizer, and between about 2% and about 6% (% w/w) of a surfactant.
2. The method of claim 1 , wherein the antimicrobial composition comprises a filming agent selected from the group consisting of chitosan, hydroxypropyl methyl cellulose, triethylene glycol, polyvinylpyrrolidone, polyvinyl alcohol-polyethylene glycol copolymers, basic polymethacrylate and combinations thereof.
3. The method of claim 2 , wherein the filming agent is a combination of chitosan, triethylene glycol, and polyvinylpyrrolidone.
4. The method of claim 1 , wherein the antimicrobial agent is dispensed daily, weekly, biweekly, monthly, bimonthly, or for longer durations of time.
5. The method of claim 4 , wherein the antimicrobial agent is dispensed daily.
6. The method of claim 1 , wherein between 0.5 ml and 9 ml of the composition is administered for every 5.0 gallons of water.
7. The method of claim 6 , wherein 1 ml of the composition is administered for every 5.0 gallons of water.
8. The method of claim 1 , wherein the desired amount is dispensed all at once or in multiple doses.
9. The method of claim 1 , wherein the composition is dispensed by dropper.
10. The method of claim 1 , wherein the aquatic environment is saltwater or fresh water.
11. The method of claim 1 , wherein the fish are adult, baby, or newly born.
12. The method of claim 1 , wherein the antimicrobial composition is administered to treat an existing microbial infection.
13. A method for reducing the incidence of bacterial infections in fish, the method comprising administering an effective amount of an anti-bacterial composition to an aquatic environment, the composition comprising between about 0.3% and about 1.3% (% w/w) of at least one plant essential oil, between about 0.1% and about 5% (% w/w) of at least one filming agent, and between about 3% and about 5% (% w/w) of a surfactant.
14. A method for reducing the incidence of parasitical infections in fish, the method comprising administering an effective amount of an anti-parasitical composition to an aquatic environment, the composition comprising between about 0.5% and about 1.5% (% w/w) of at least one plant essential oil, between about 0.1% and about 5% (% w/w) of at least one filming agent, and between about 3% and about 5% (% w/w) of a surfactant.
15. A method for reducing the incidence of protozoal infections in fish, the method comprising administering an effective amount of an anti-protozoal composition to an aquatic environment, the composition comprising between about 0.5% and about 1.3% (% w/w) of at least one plant essential oil, between about 0.1% and about 5% (% w/w) of at least one filming agent, and between about 3% and about 5% (% w/w) of a surfactant.
