Abstract: (92 Views) |
Aquaponics is the integration of a hydroponic systems with recirculating aquaculture that removes waste and metabolites produced by farmed fish from the environment through nitrification and their absorption by plants. Production in an aquaponic system plays an important role in preserving water, soil, the environment, and food security. In the present study, the combined production of tilapia and edible plant products and fodder in two separate aquaponic systems with different water salinities on a home scale with a space of 1 m3 for fish farming and 3 m2 for plant cultivation was investigated over a 7-months period. The production rate of hybrid red tilapia Oreochromis niloticus × O. mossambicus was 21.6 kg/m3 in set 1 (water salinity of 2.3 ppt) and 20.9 kg/m3 in set 2 (water salinity of 11 ppt). During the 7-month production period on 3 m2 of the cultivation area, in Set 1, peppermint (Mentha piperita), beet (Beta vulgaris) and rocket (Argula eruca sativa) had significant yields of 28.6, 28 and 13.7 kg respectively, and in Set 2, glasswort (Salicornia sp.) had a good yield of 64.8 kg. The combined production of fish and plants in home-grown aquaponics systems with the aim of constant access to fresh and healthy food plays an important role in providing food for the household and contributing to the local economy, especially in small and rural communities.
