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.

Seasonal nitrate drawdown transitions lake ecosystems from phosphorus to nitrogen deficiency in annual cycles

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Phytoplankton biomass is often limited by nitrogen (N) and/or phosphorus (P). Quantifying the relative availability of N and P in an ecosystem is useful in indicating nutrient limitation status. In subtropical lakes, nitrate availability generally follows a seasonal pattern with maxima in the late winter/early spring and minima in late summer ...

Disentangled Assembly Graphs Reveal Hidden Eukaryotic Diversity in eDNA Metagenomic Data

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Genome assembly graphs contain valuable yet frequently overlooked information that can enhance assembly completeness by revealing contig connectivity. Here, we demonstrate how leveraging these information‐rich structures enables the discovery of hidden microeukaryotic diversity in environmental DNA shotgun metagenomic datasets.

ChloroScan: Recovering Plastid Genome Bins From Metagenomic Data

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Genome‐resolved metagenomics has contributed greatly to discovering prokaryotic genomes. When applied to microscopic eukaryotes (protists), challenges such as the high number of introns and repeat regions found in nuclear genomes have hampered the mining and discovery of novel protistan lineages.
