Application a solar-powered sediment lifting device in silver barb fish culture

ABSTRACT

This study assessed the effectiveness of a solar-powered sediment lifting device (SSLD) in a fish pond. The experiment was conducted by installing the SSLD in a pond with silver barb (Barbonymus gonionotus) for50 days. The study showed that total ammonia nitrogen and nitrite in the pond without the SSLD were significantly higher than in the pond with the SSLD (p < .05). The total nitrogen, total phosphorus, total organic matter, and total organic carbon in the sediments, were significantly higher in the pond without the device than in the pond with the SSLD (p < .05). Weight gain and daily weight gain of the fish in the pond with the SSLD were higher than in the pond without the device (p < .05). This experiment revealed that installing the SSLD in fish pond culture decreases total organic matter in the water and sediments of the pond.
