Iranian Experts Use Biofloc Technology to Enhance Water Quality
“The Biofloc method works based on the accumulation of microorganisms and organic matter in pond water,” Amin Safavi, the managing director of the company stationed at Islamic Azad University’s Lahijan branch, told ANA.
“In this system, microorganisms help reduce ammonia and other toxic substances by decomposing organic matter and nitrogen compounds in the water. This process makes the pond water continuously purified and eliminates the need for frequent replacement. In this method, we can have a very high density of fish,” he added.
“This method does not require much water and we can even use rainwater to irrigate the breeding area. Other advantages of this method include a 35% reduction in feed costs, which is very beneficial, and we no longer need UV, ozone, sand filters, and the additional costs of pumping and water extraction,” Safavi said.
In a relevant development in April, a cooperation agreement was signed between 12 companies and groups of stakeholders in the field of fish farming to create a value chain for caged fish farming in the Caspian Sea region in Northern Iran.
A total number of 12 influential companies and groups with a long history in various sectors of the industry, including the production of hatched eggs, baby fish nursery as the primary production input, health, nutritional and executive management of fish farms in cages, fish farms on land, export and trading of products, fishing unions and feed production factories, have agreed to create a value chain with a production capacity of 1,500 tons of fish by using all the country's hardware and software technologies to accelerate the development of the cage fish farming industry in the Northern waters of Iran.
The most important projects identified for the creation of this chain value include the completion of the technological equipment of the caged fish farm, including imaging, farm management software, etc., completion of the equipment and the optimization of the intermediate farms, including the nano-bubble, ozone, and filtration systems, and creation of the production-line of value-added products from fish waste to supply the raw materials of aquatic feed, concentrate production project to increase the safety of farmed fish by using medicinal plants to reduce the consumption of antibiotics, completing and equipping the processing unit including IQF machine, automatic processing, etc.
Design and construction of support float for caged fish breeding farm, completion of surveillance system equipment for breeding and nursery unit, implementation of the project for selection and production of Iranian triploid eggs, creation of a specialized feed production line for fishmeal, and supply of specialized vehicle for transporting fish are other projects to be implemented by the companies.
