Results of this study demonstrated that a commercial, granular, SCP-based algaecide corresponding to 2.5 mg/L H2O2 can be recommended as an eco-friendly strategy to effectively remove populations of the cyanobacterium Planktothrix sp. without compromising water quality or other plankton communities.
Cleaning is part of the daily management to ensure adequate rearing conditions, but additional water treatment is occasionally required to further improve the water quality. A disinfectant like sodium percarbonate can reduce the bacterial load.
An over-reliance on medical and chemical controls, along with warming waters, led to a surge in sea lice. With such treatments waning in effectiveness, operators turn to other, safer measures.
Formalin use is a common fish parasite control, but the chemical’s potential work safety and ecological impacts are leading to a search for alternatives.
Hydrogen peroxide is a candidate for water treatment in aquaculture systems for it has antimicrobial effects and easily degrades to harmless byproducts.
In studies, sodium carbonate peroxyhydrate proved an effective alternative to formalin and hydrogen peroxide as a treatment for controlling fungal infections of catfish eggs and improving hatch rates.
