Fish disease diagnosis using an optical immunoassay virus detection kit


A Singapore research institution has developed an Optical Immunoassay Iridovirus Detection Kit for rapid on-site diagnosis of fish disease. This kit will be useful in marine farm biosecurity risk management and will help reduce the mortality rate of freshwater aquatic animals. The institution is seeking industry partners (SMEs of any sizes or MNEs) in the agriculture and fishing sectors for licensing partnerships.

Partner sought

The Singapore institute seeks to partner MNEs or SMEs of any sizes via a licensing agreement. The partners sought can be industry players in agriculture and fishing. The partners can help in commercializing the assay kit and also in distribution of the assay kit to their customer base.


The Singapore research institution has developed the Optical Immunoassay (OIA) detection kit based on the identification and diagnosis of Iridoviruses in aquatic farms. Iridoviruses can be very effective in spreading diseases in freshwater fishes and can also increase the mortality rate in more than 32 species of marine, ornamental, and freshwater fish species including Gourami, Dwarf gourami, angel, platys, guppies, and doctor fish. The Iridoviral disease is one of the main viruses in the South-East Asian region which can affect the population of food and ornamental fishes. This virus detection kit will be very handy for conducting post vaccine fish health monitoring in aquaculture farms. This OIA kit will also enable rapid screening of the fish population for better quarantine management as compared to conventional detection technologies, which are labour intensive and also time consuming. The immunoassay kit will be used for frequent fish health monitoring which will provide actionable recommendations to farmers and help them perform intervention measures that can eliminate a possible epidemic among the aquatic animals. Besides, it will protect aquaculture farmers against financial losses associated with such unprecedented events. The research institution is keen to partner SMEs of any sizes or MNEs such as those from the aquaculture industries to license and further develop and commercialise this technology.

Advantages and innovations

The Immunoassay Kit consists of tissue and blood processing gadgets along with specific antibody response devices which can detect both the virus and the host in a single test. This kit has many features including the following: • It has a rapid detection time of Iridoviruses within 25 minutes and a total analysis time of less than 2 hours. This detection test is faster than conventional detection technologies. • It is completely field deployable with less use of manual labour and is highly user friendly with reduced logistics load and increased visual read out. This enables end users to make better decisions while monitoring fish health. • This kit also possesses 100% specificity and more than 90% sensitivity. This enables the detection limit of 5000 viral particles per millilitre (ml) of processed tissues or blood samples. The immunoassay kit can also be customized so as to enable the detection of multiple pathogens of interest to aquaculture farmers. This enhances farmers' decision making systems, ensuring an increase in return on investment for them.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
