Aquatic Toxicology, 2023 The production and release of chemicals from human activities are on the rise. Understanding how the aquatic environment is affected by the presence of an unknown number of chemicals is lacking. We employed the chemical activity concept to assess the combined effects of hydrophobic organic contaminants on the phytoplankton species Rodomonas salina ...

Culture conditions affect the nutritional value of the copepod Acartia tonsa
Journal of Agricultural and Marine Sciences, 2015 Live feed are still necessary for the rearing of larval stages of several fish species, especially marine ones. Compared to Artemia, copepods are of superior quality. This is based on a suite of traits like size, movement, and nutritional value. Copepods

Food quality affects secondary consumers even at low quantities: an experimental test with larval European lobster. [PDF]
PLoS ONE, 2012 The issues of food quality and food quantity are crucial for trophic interactions. Although most research has focussed on the primary producer-herbivore link, recent studies have shown that quality effects at the bottom of the food web propagate to ...

Ecology, Volume 107, Issue 1, January 2026.Abstract Biologists often use organismal thermal tolerance to help explain or forecast responses of populations to climate change. Yet many studies quantify thermal tolerance under isolated laboratory conditions despite extreme events, such as heatwaves, often coinciding with other stressors such as nutrient or food limitation.

Copepod population-specific response to a toxic diatom diet. [PDF]
PLoS ONE, 2012 Diatoms are key phytoplankton organisms and one of the main primary producers in aquatic ecosystems. However, many diatom species produce a series of secondary metabolites, collectively termed oxylipins, that disrupt development in the offspring of ...

The effect of cell density on biomass and fatty acid productivity during cultivation of Rhodomonas salina in a tubular photobioreactor [PDF]
, 2020 The microalga Rhodomonas salina is widely used in aquaculture. There is a need for optimization of the growth of the microalgae and its content of essential fatty acids.

Aquaculture Research, Volume 2026, Issue 1, 2026.Efficient production of high‐quality microalgae is essential for marine aquaculture, yet large‐scale cultivation of the cryptophyte Rhodomonas salina remains labor‐intensive and technically challenging. In this study, a 500‐L tubular photobioreactor (PBR) was evaluated and compared three control strategies—manual control, a programmed standard dilution

The effect of algae diets (Skeletonema costatum and Rhodomonas baltica) on the biochemical composition and sensory characteristics of Pacific cupped oysters (Crassostrea gigas) during land-based refinement [PDF]
, 2017 Oyster refinement, a common practice in France, is aimed at increasing the weight of oyster tissue and influencing the taste properties of the refined oysters. Refinement usually takes place in land-based systems where the oysters are fed with relatively
