In contrast to the traditional vaccine feeding by injection, the innovational oral-taking vaccine for fish breeding has been newly developed by Taiwan National Cheng Kung University, promising a survival rate over 80%. Afterwards, a cooperative contract based on this achievement was signed up on 16^th October between the university and the company from Saudi Arabia for the technology extension to the Red Sea aquaculture.

According to the research institute, the developed injection process operating on aquatic food chain, need to be completed in steps:

Step 1 Escherichia coli feeding to shrimp, with the implanted vaccine;

Step 2 Feeding small fish with the shrimp from step 1

Step 3 By the devouring of those small fish, big fish is successfully implanted with the vaccine.

The whole experimental operation has been mainly operated on grouper, presenting a survival rate over 80%.
