The Taedonggang Eel Farm has applied the microflora technology, an advanced fish breeding technology in the world, to all eel breeding ponds covering thousands of square metres.
The microflora technology makes it possible to form a food chain by artificially cultivating useful microorganisms in water to feed fish with microorganisms ingesting the excrement of fish. It is now recognized as an advanced technology in fish farming in the world as it enables farms to breed fish without changing water while solving the shortage of feed.
“We conceived an idea to form a microflora in dozens of fish breeding ponds by way of multiplying and cultivating spores of microorganisms and paid attention to the making of a mud cultivation device needed for the cultivation of spores of microorganisms,” said section chief Pak Chol Hwan.
In the course of it, researchers solved scientific and technical problems including the technology for making the mud cultivation flasks maintain their position without being damaged in a quick shake in the device and the installation of thermostat and others.
And they found out scientific and technical indices for reducing the content of ammonia and nitrous acid which grows due to the excrement of fish and leftovers of its feed in fish ponds which are inoculated with spores of microorganisms in close collaboration with scientists of the microbiology institute of the State Academy of Sciences.
While performing an in-depth analysis of water quality, they also discovered that the key to success is to provide the proper amount of carbon and nitrogen sources.
By introducing the new technology into production of fish, the farm not only solved the feed problem of fish but also saved a large amount of labour and coal which were used for changing water at certain intervals.
Most important is that it increased the fattening rate of eel by 10-20 percent and halved the death rate.
