Optimizing Microalgae Nutrition for Sustainable Aquafeed Production
Marine microalgae are proving that sustainable aquafeed does not require a compromise in performance. In this study, *Tetraselmis chuii* and *Nannochloropsis oculata* thrived in a modified F/2-NPK medium, replacing conventional macronutrients with a commercial fertilizer. Peak biomass reached 0.603 g L⁻¹, with protein content holding above 34% across treatments. The preliminary *Artemia* assay showed steady growth, though the authors rightly frame these results as a starting point, not a final verdict.
Cyanobacteria's Resilience: Metabolic Shifts During Extended Nutrient Deprivation
When *Synechocystis* sp. CCNM 2501 faces 30 days of starvation, its response depends entirely on which nutrient is missing. Nitrogen deprivation drives progressive chlorosis and a final collapse of carotenoids. Phosphorus deprivation triggers an opposite, protective surge. These are not identical stress responses. They are distinct metabolic strategies. Understanding this distinction is essential for predicting bloom persistence in eutrophic waters. Our related work on *Gymnodinium catenatum* similarly explores how nutrient shifts reshape bloom dynamics at the proteome level.
Microalgae-Larvae Carbon Transfer: A Pathway to Sustainable Aquaculture.
A 33% carbon transfer efficiency from microalgae to shrimp larvae is a measurable, validated starting point. This study on *Litopenaeus vannamei* quantifies a biological pathway that has remained poorly understood. By calculating that global hatchery seed production retains approximately 9.2 tons of carbon annually, the research gives aquaculture a calibrated, empirical tool for carbon footprint assessments. Understanding drives protection. For deeper genomic context on algal symbiosis, see our related coverage of Symbiodiniaceae Minicircles.
Harnessing Nature: Bioactives for Sustainable Aquaculture Reproduction
Synthetic hormonal induction remains the workhorse of aquaculture reproduction, but it is not the only tool worth studying. This review makes that clear by weighing microalgal and plant-derived bioactives against conventional protocols, and the evidence points to complement, not replacement. What stands out is the mechanistic honesty: direct endocrine effects are less consistently shown than nutritional or antioxidant support. That distinction matters. For readers tracking how reproductive science evolves, related coverage on pacu ovulation protocols offers a practical counterpoint.
