Noakhali University of Science and Technology (NOUST) has succeeded in applying mechanization and scientific methods in fish farming. This important progress has given new hope to fisheries researchers. They believe that by cultivating fish in this way, on the one hand, it is possible to produce twice as much fish with the same labor and cost, and this fish can also make an important contribution to the country's economy.
Professor Dr. Abdullah Al Mamun of the Fisheries and Marine Science Department of NOUST visited the project area yesterday to see the success of the project titled 'Developing an Advanced Model for Intensive Fish Production through Mechanization'.
During the visit, Vice-Chancellor Professor Dr. Muhammad Ismail said that farmers will succeed in tilapia farming by using aerators through solar systems. As a result, a completely renewable system has been introduced. If the practical application of this research spreads among ordinary fish farmers, fish, one of the sources of protein demand in the country, will be more easily available and affordable. At the same time, environmentally friendly fish farming will attract foreign buyers. This production method will also contribute significantly to the country's economic growth.
At that time, he urged the representatives of the project's financial partners, the 'Bangladesh Academy of Science' and the 'US Department of Agriculture', to continue their cooperation in such research in the future.
The Vice Chancellor also said that a meeting was held between Nobipravi and the Bangladesh Fisheries Research Institute at the Ministry of Fisheries and Livestock last week. Both institutions will benefit if the memorandum of understanding is signed between the two parties.
Researchers said that a three-year study has shown that using aerators at the right time and method can increase tilapia production per hectare by almost double compared to the conventional method. For a long time, the use of aerators was limited in Bangladesh, except for hatcheries and some shrimp enclosures. Despite the potential, the desired results were not obtained due to a lack of awareness among farmers, high electricity costs, and a lack of information about which type of aerator to use and when. From this reality, Professor Mamun conducted long-term research on the water quality, oxygen supply, and productivity of the pond. His research proved that providing bubbles through diffuser discs at the bottom of the pond and operating a paddle aerator from above maintains sufficient oxygen at all levels of the water.
During the inspection, among others, Bangladesh Academy of Science representative and member of the Technical Committee Professor Dr. Abu Tayyab Abu Ahmed, Chairman of the Fisheries and Marine Science Department of Nobiprobi Professor Dr. Mehedi Mahmudul Hasan, Professor Dr. Md. Rakeb ul Islam, Professor Dr. Debashish Saha and research associate Mithun Roy were present, along with teachers, officials, students and journalists.
