Assessing the Utilization of Waste from Aquaponics System as Nutrients Contributing to the Growth of Water Spinach and Tank Fish

Abstract

Due to having plentiful water resources, Bangladesh offers significant potential for fish farming. Aquaponics as a bio-integrated multi-trophic system that combines hydroponics (the growing of soilless plants) and re-circulate aquaculture (the culture of fish) to create a symbiotic relationship between fish, microorganisms and plants. This study was carried out for 95 days at the aquaponic laboratory of Khulna Agricultural University (KAU) to access the
utilization of waste from tank water as nutrients affecting the growth of both water spinach and fish using two different medias-only bricklets (
