A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

Theoretical Analysis of the Potential of Silver Carp Hypophthalmichthys Molitrix in the Control of Water Blooming by Different Species of Cyanobacteria [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2009
The possibility to use silver carp (Hypophthalmichthys molitrix) in the control of water blooming by cyanobacteria is theoretically analyzed. To attain this goal the dynamic model has been developed, describing communities of two species of cyanobacteria:

Atmospheric Ammonia Deposition: A Significant Source of Nitrogen to an Oligotrophic Lake and Its Watershed

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract The increasing frequency of toxic cyanobacterial blooms (TCBs) in freshwater lakes in recent years has been problematic, both in terms of our understanding of basic drivers, and attempts to manage them. While phosphorus has been determined to limit the growth of blooms, some cyanophytes manufacture toxins with a high nitrogen (N) demand, so ...

Differential Effects of Hydrogen Peroxide and L-Lysine Treatments on the Growth of Freshwater Cyanophyta and Chlorophyta

Ecologies, 2023
Harmful cyanobacterial blooms of the toxin-producing Microcystis have become a growing problem for Southwest Florida freshwater bodies. Recently, a 2016 bloom in Lake Okeechobee and a 2018 bloom in the Caloosahatchee River both led to the declaration of ...

Physiological responses of Microcystis aeruginosa against the algicidal bacterium Pseudomonas aeruginosa

Ecotoxicology and Environmental Safety, 2016
Proliferation of cyanobacteria in aquatic ecosystems has caused water security problems throughout the world. Our preliminary study has showed that Pseudomonas aeruginosa can inhibit the growth of cyanobacterium, Microcystis aeruginosa. In order to explore the inhibitory mechanism of P.

DoesMicrocystis aeruginosahave quorum sensing? [PDF]

FEMS Microbiology Letters, 2012
Quorum sensing (QS) is a system of cell-to-cell communication by means of intercellular signaling molecules to coordinate a set of targeted gene expression or repression in many Gram-negative bacteria; it plays important roles for bacteria in adaptation to adverse environmental conditions.

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Occurrence of Microcystis aeruginosa and microcystins in Río de la Plata river (Argentina)

Acta Toxicológica Argentina, 2007
This paper is the first report on microcystins producer blooms of Microcystis aeruginosa in the Argentinean coast of the Río de la Plata river, the most important drinking water supply of Argentina. The distribution of toxic cyanobacterium Microcystis cf.

Characterization of the Biocidal Spectrum of Extracellular Filtrates of Microcystis aeruginosa [PDF]

Indian Journal of Microbiology, 2011
The effect of dichloromethane (DCM) and ethyl acetate (EA) extract of a cyanobacterium, Microcystis aeruginosa was evaluated against unicellular cyanobacteria and the phytopathogenic fungus Rhizoctonia solani. Fractionation of the filtrate showed the presence of five spots of different Rf values on silica gel coated plates indicating the presence of a ...
