Published: Dec. 18, 2023

This comprehensive review explores aquaponics as an environmentally friendly solution aligned with SDGs and food sovereignty, assessing various aspects from system design to automation, weighing social, economic, environmental benefits through literature case studies. However, challenges persist in obtaining organic certification legislative recognition, hindering its growth. Achieving remarkable water use efficiency, up 90%, relies on adaptable fish species like Nile tilapia carp. Nutrient-rich feeds notably benefit low-nutrient-demanding greens. Ensuring quality efficient nitrification are pivotal, supported by IoT systems. Despite integrating Industry 4.0 involves complexity cost barriers, necessitating ongoing innovation. Economies of scale supportive horticultural policies can bolster viability. Aquaponics, known for efficiency enhancing crop yields while minimizing waste, is expanding globally, especially water-scarce regions. pioneered the University Virgin Islands, Europe, Spain, Denmark, Italy, Germany.

Integrated agriculture-aquaculture as an alternative to improving small-scale fish production in Zambia

Frontiers in Sustainable Food Systems, Journal Year: 2023, Volume and Issue: 7

Published: May 10, 2023

Aquaculture is a significant industry in food production, and its contribution to nutrition security well acknowledged. Zambia’s aquaculture production has continued increase significantly, thus playing key role supplying animal protein sources for human consumption. However, recent estimates show that 75% of the national comes from large-scale commercial producers despite being by far minority while majority small-scale contribute remaining 25% total annual production. This low attributed insufficient financial resources, poor management utilization farm lack access competitive markets, more recently changing climate. In this research, we examine viability integrated agriculture-aquaculture (IAA) as means Zambia boost their output numerous obstacles they face. addition, could prevent farmers adopting IAA have been emphasized. We conclude potential dramatically Zambia, but information understanding must be improved make it feasible alternative.

Optimizing nutrient utilization, hydraulic loading rate, and feed conversion ratios through freshwater IMTA-aquaponic and hydroponic systems as an environmentally sustainable aquaculture concept

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: June 27, 2024

Abstract Water quality in land-based fish production can be controlled through either instantaneous water exchange or costly wastewater treatment followed by recirculation. Agricultural-aquaculture integration is an excellent alternative technique for reducing nutrient discharge levels, boosting profitability, and converting culture into valuable products. The current study employed a solar energy system to power two separate IMTA-aquaponics systems (Nutrient Film Technique, NFT, Floating Raft Systems, FRS) the cultivation of Nile tilapia, African catfish, thin-lipped grey mullet, freshwater crayfish, mussels, variety vegetables. Tilapia catfish were fed exclusively on diets under IMTA system. All from tilapia ponds, both dissolved solid, flows sequentially ponds containing other cultivated species. then system's terminal point NFT FRS before returning allowing complete control flow throughout this entire circular Two 147-day cycles concluded. results second cycle are reported.

The objective of this article is to review the historical development rice–aquatic species (RASp) integration and analyze factors that affect its performance. Compared rice monoculture, system has a more significant impact on farm production, income, land (L), water use efficiency (WUE), net revenue, labor (LBUE) reduction. Although concurrent alternate cultivations increase unit efficiency, cultivation requires 26% than monoculture. Furthermore, RASp farming promotes environmentally-friendly by reducing pesticides (insecticides herbicides), decreasing CH4 emissions approximately 14.8–22.1%, enhancing quality. These findings suggest fish in fields could be integrated into extensive aquaculture. Finally, global cooperation necessary transfer knowledge about technology, particularly from China, research needed evaluate effects context climate change practical efficiency.
