Countries with Biggest Production Gain. Great examples of groundbreaking technology and innovation can be found in businesses across all sectors of the UK economy, from life sciences and software to … Mattson is particularly interested in CEA. The aim of the present study was to evaluate the use of the technology we have named for the first time as FLOCponics (biofloc + hydroponic) (FP) and conventional aquaponics (AP) systems in producing Nile tilapia (Oreochromis niloticus) juveniles and lettuce (Lactuca sativa). Lettuce has been grown in the United States since colonial times. If the plants are sufficiently hardened, they will withstand freezing. Also, aquaponics contributes to save water and for the maximum utilization of nutrients and culture areas. Production technology of Lettuce The lettuce plant is a hardy annual that grows best in nitrogen-rich, loose soils that have a pH ranging between 6.0 and 6.8. A wire-bound or waxed fiber carton designed to hold 20 to 24 heads is used. Optimum temperature for growth and development is 60 to 650F.
