What are the features of the parasite control technology developed by the Okinawa Churaumi Aquarium?

This technology applies artificial amniotic fluid techniques developed in 'shark artificial uterus' research, using a solution of seawater, freshwater, and urea to safely remove parasites from fish species that cannot be treated with freshwater baths.

What types of fish is this control method suitable for?

It is particularly effective for jawless fish (such as hagfish) and cartilaginous fish (such as sharks and rays) that are sensitive to freshwater environments.

What is the patent information for this technology?

The invention is named 'Method for Removing Monogeneans from the Skin Surface,' with Patent Number 7866821, registered on May 20, 2026.

Can you explain the specific procedure for the control method?

The infected fish are immersed in a solution of seawater, freshwater, and urea (urea water) for about 5 minutes to remove monogeneans from their skin surface.

Is this technology already in practical use?

Yes, it has already been used at the Okinawa Churaumi Aquarium to treat a captive purple hagfish.
