Removing cyanobacteria and associated toxins in aquaculture ponds

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.

Biofloc technology holds potential for carnivorous fish species

Juvenile carnivorous African catfish performed well in biofloc-based systems, which could help produce better quality and more disease-resistant seed of this important aquaculture species and support the expansion of African catfish farming industry.

Aquamimicry: A revolutionary concept for shrimp farming

Aquamimicry simulates natural, estuarine production conditions by creating zooplankton blooms as supplemental nutrition to the cultured shrimp, and beneficial bacteria to maintain water quality. Better-quality shrimp can be produced at lower cost and in a more sustainable manner.

Dietary organic acids used as growth promoters, anti-microbials

A feeding trial measured growth, nutrient utilization and faecal/gut bacterial counts in triplicate groups of red hybrid tilapia (Oreochromis sp.). Study results show that dietary organic acids can potentially replace OTC as a growth promoter and anti-microbial in tilapia feeds.

Microencapsulated organic acids aid shrimp culture

A novel blend of organic acids (OAB) microencapsulated in a lipid matrix and supplemented in the diets of Litopenaeus vannamei enhanced their growth, phosphorus utilization, resistance to Vibrio harveyi and immunity. This may have implications as an eco-friendly prophylactic strategy.
