Cultivation of Anabaena sp. at Different Phosphorus Excess Concentrations: Growth Parameters, Value‐Added Metabolites, and Microcystin‐LR Production

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Phosphorus is a key driver of cyanobacterial proliferation and the production of secondary metabolites in freshwater ecosystems. In this study, the effects of different phosphorus concentrations, including 7.10 (control treatment), 7.74, 8.38, and 9.66 mg L−1 (CP230, TP250, TP271, and TP312, respectively), on growth, valuable biochemicals, as ...

Culturing the solitary ascidian Phallusia nigra in closed and open water systems for tropical environmental research

Limnology and Oceanography: Methods, Volume 23, Issue 10, Page 700-714, October 2025.
Abstract Marine and coastal ecosystems have been undergoing dramatic shifts due to global environmental changes. The rise in seawater temperature, ocean acidification, hypoxia, eutrophication, and anthropogenic pollution severely affects marine organisms.

Changes in mortality rates during the larval stage of the Pacic white shrimp (Litopenaeus vannamei ) on the basis of algal (Chaetoceros calcitrans or Tetraselmis suecica) food density/Cambios en las tasas de mortalidad durante el estadio larval del camarón blanco del Pacíco (Litopenaeus vannamei ) en base a la densidad de alimento algal (Chaetoceros

Ecosistemas y Recursos Agropecuarios, 2016
In the shrimp culture, larval stages have high mortality rates, particularly in the zoea stage, this because to the star of phytoplankton feeding and an inadequate microalga species and cell density used in commercial hatcheries.

Mass production of Tetraselmis suecica (Kylin) Butch. (Prasinophyceae), under different concentrations of nutrients and additions of carbon dioxide

Ciencias Marinas, 1991
A series of four experiments with Tetraselmis suecica was carried out under laboratory conditions in order to learn the production yield in volumes of 1,000 litres, with salinity of 28‰, with absence and addition of buffer and carbon dioxide, air flow ...

Artemia Enrichment Strategies: A Comprehensive Review of Nutritional Enhancements With Emphasis on Fatty Acid Profiles in Aquatic Species

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Artemia (brine shrimp) is a foundational live feed in global aquaculture, renowned for its adaptability, ease of production, and favorable nutritional profile. However, in its natural state, Artemia contains suboptimal levels of highly unsaturated fatty acids (HUFAs), particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA ...

The Selective Supercritical Extraction of High-value Fatty Acids from Tetraselmis Suecica Using the Hansen Solubility Theory

Chemical Engineering Transactions, 2019
The aim of this work was to test the utility of the Hansen theory to predict the best cosolvent for supercritical carbon dioxide (sc-CO2) to reach the selective extraction of fatty acids from Tetraselmis suecica.

Exposure of Greenshell Mussel Spat (Perna canaliculus) to Stressors for Producing Single‐Spat From Collector Ropes

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Nursery culture can improve the efficiency of mussel aquaculture by reducing the high losses of spat and overcoming inconsistencies in wild‐spat supplies. The success of nursery systems depends on the availability of unattached single or singulated spat, which requires the separation of spat from their associated settlement substrates (i.e ...

Isolation of Microalgae from Mediterranean Seawater and Production of Lipids in the Cultivated Species

Foods, 2020
Isolation and identification of novel microalgae strains with high lipid productivity is one of the most important research topics to have emerged recently. However, practical production processes will probably require the use of local strains adapted to

Effect of sulfate availability on phytoplankton stoichiometry

Journal of Phycology, Volume 61, Issue 4, Page 895-910, August 2025.
Abstract Sulfur (S) is a key element in multiple metabolic pathways of phytoplankton cells. The effect of S availability on phytoplankton elemental quotas and stoichiometry has been addressed in few studies, using a limited number of species and with contradictory results.

The Use of Flocculation as a Preconcentration Step in the Microalgae Harvesting Process

Physiologia Plantarum, Volume 177, Issue 4, July/August 2025.
ABSTRACT Flocculation is a widely utilized separation technique in colloid chemistry, the chemical industry, and wastewater treatment. However, its application in microalgal biomass production and downstream processing remains limited. Biomass harvesting represents a significant cost factor in large‐scale microalgae production, with the separation of ...
