Abstract

Aquaculture waste is one of the major concerns in the aquaculture industries that cause water pollution. Worldwide statistics show that over 80% of wastewater is created, while 95% is released into untreated streams. Photosynthetic Bacteria (PSB) is assumed to be one of the natural wastewater treatments in aquaculture systems and was formed from natural sources that may replace chemical treatment in improving water quality, also encouraged solving the pollution by using organic resources. PSB are widely utilised in environmental waste control, ecological restoration, animal husbandry, agriculture, aquaculture, the chemical industry, and the pharmaceutical business, and are thought to have dual benefits as follows. PSB breaks the traditional carbon cycle and nitrification by growing photographically in the wastewater treatment process, effectively fixing CO2 and high nitrogen levels. Remediating wastewater pollution from aquaculture and identifying a natural source microbe that is generated, viable, and efficient for treating aquatic effluent have been recognised as crucial issues in this study. Therefore, the potential of PSB will be determined based on the type of wastewater used from the aquaculture system. In order to gain the potential of PSB, four types of wastewater were collected from the hatchery pond, hatchery tank, big drainage area, and another freshwater pond near the Universiti Putra Malaysia Bintulu Campus (UPMKB). During this study, the effectiveness of different PSB samples was determined and isolated by examining and analysing the water quality recorded (ammonia, nitrite, nitrate, pH, and temperature) in treating Glowlight Tetra (Hemigrammus erythrozonus). As a result, sample from (H1; H2; H3; H4; H5; H6; H8; H9; H10) was the potential of PSB produced from hatchery ponds wastewater which will be utilised to help improve and treat the water quality in the aquatic systems.
