abstract
The experiment was conducted for 108 days from 27 September 2016 to 11 January 2017 in Bolashpur, Pagla Bazar and Boyra, the peri-urban areas of Mymensingh sadar to assess the integration effect of aquaponic system with wish pond concept in producing safe food by addressing water pollution associated with wish pond alone. Juvenile tilapia (Oreochromis niloticus) of 5.97 ± 1.36 cm and 4.73 ± 3.97 g and walking catfish (Clarias batrachus) of 6.93 ± 1.35 cm and 2.77 ± 1.88g initial size were stocked at the rate of 100 fish/pond. Commercial floating pellet feed were used at a rate of 10% body weight of fish. Survival rate, total production of fish and vegetables were higher (84%, 18.78 tons/ha/108 days and 58.64 tons/ha respectively) in wish pond-aquaponics system than the wish Pond system (78%, 15.80 tons/ha/108 days and 47.07 tons/ha). Nutrient loads were significantly lower in wish pond-aquaponics system at the end because of utilization by the plants therefore performed better than the wish pond system in maintaining water quality.
