The Effect of Natural Zeolite (Clinoptiolite) on Aquaponic Production of Red Tilapia (Oreochromis sp.) and Lettuce (Lactuca sativa var. longifolia), and Improvement of Water Quality
The study investigates the impact of natural zeolite (Clinoptiolite) as a bed medium in an aquaponic system on the growth of red tilapia (Oreochromis sp.) and lettuce (Lactuca sativa var. longifolia), as well as its effects on water quality. The experiment utilized a completely randomized design with two treatments: a control group without zeolite and a treatment group using zeolite. Each experimental unit contained 42 lettuce seedlings.
Results indicated that the treatment with zeolite significantly enhanced the growth of both fish and lettuce. The individual weight of tilapia increased from an initial mean of 6.23 g to 37.50 g in the zeolite treatment, compared to 32.50 g in the control. Lettuce yield was also markedly higher in the zeolite treatment (1507 g/unit) compared to the control (275 g/unit). Water quality parameters showed that total ammonia-N, phosphorus, and potassium concentrations were significantly lower in the zeolite treatment, suggesting improved water quality.
The study concludes that using natural zeolite as a bed medium in aquaponic systems can effectively promote plant growth and enhance water quality, thereby supporting sustainable aquaculture practices.
This research paper is significant in the field of aquaculture and sustainable agriculture as it explores innovative methods to improve the efficiency of aquaponic systems. The findings contribute to ongoing discussions about sustainable practices in aquaculture, particularly in managing waste and enhancing productivity. By demonstrating the benefits of natural zeolite, the study offers practical insights for aquaponic farmers and researchers looking to optimize growth conditions for both fish and plants while maintaining water quality. The research highlights the potential of integrating natural materials into aquaculture systems, which can lead to more environmentally friendly practices and reduced ecological impacts.
