Biofloc technology as an alternative aquaculture practice in Bangladesh

Abstract

Bangladesh is one of the most densely populated countries in the world and due to rapid growth of population and expansion of human settlement water bodies for fish production are shrinking. Thus, intensification of aquaculture with the help of innovative technology is required to ensure nutrition and alleviating hunger, poverty and unemployment. Biofloc technology, which is based on the concept of recycling waste nutrients and zero water exchange, is considered as a cost effective, environment friendly and sustainable way of aquaculture. With higher growth and survival rate of fish, high stock density and lower feed cost this technology can increase the productivity of aquaculture sector and ensure sustainability. As this innovative technology is still at the early stages of diffusion in Bangladesh, promotion and adoption of this aquaculture practice is critical. So, effective information exchange and farmer-to-farmer learning are critical for the growth and adoption of this technology in the long-term. Infrastructure development, government policy and support can reduce the uncertainties about this technology and that can benefit both farmers and consumers.

Bangladesh on üks kõige tihedamalt asustatud riike maailmas ning rahvaarvu kiire kasvu ja inimasustuse laienemise tõttu vähenevad kalakasvatuseks sobilikud veekogud. Seega on toidu tagamiseks ning nälja, vaesuse ja töötuse leevendamiseks vaja laiendada ja intensiivistada vesiviljelust uuendusliku tehnoloogia abil. Biofloci kala tanki tehnoloogiat, mis põhineb jääktoitainete ringluse ja mittevoolava vee kontseptsioonil, peetakse kulutõhusaks, keskkonnasõbralikuks ja jätkusuutlikuks vesiviljelusviisiks. Suurema kalakasvu ja ellujäämismäära, suure kalade asustustiheduse ja madalamate söötmiskulude tõttu võib see tehnoloogia suurendada vesiviljelussektori tootlikkust ja tagada selle jätkusuutlikkust. Kuna selle uuendusliku tehnoloogia levik on Bangladeshis alles algusjärgus, on selle vesiviljeluspraktika edendamine ja kasutuselevõtt kriitilise tähtsusega. Niisiis on tõhus teadmussiire ja tootjalt-tootjale õppimine selle tehnoloogia pikaajalise kasvu ja kasutuselevõtu jaoks ülioluline. Infrastruktuuri arendamine, valitsuse poliitika ja toetus võivad vähendada selle tehnoloogiaga seotud ebakindlust ning sellest võivad kasu saada nii tootjad kui ka tarbijad.
