The Effects of Different Light Spectra, UV and Extreme Temperature on the Physiology of Endosymbiotic Jellyfish Cassiopea andromeda

open access: yesMarine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT The endosymbiotic jellyfish Cassiopea andromeda represents a yet untapped marine species that could be targeted as a new source for bioproducts, including food and feed. Also, the potential use of contained valuable ingredients, such as carotenoids and other antioxidants, under controlled aquaculture conditions might be a particularly ...

Cultivation of the microalgae Chaetoceros gracilis to feed the rotifer Brachionus plicatilis

open access: yesCuadernos de investigación UNED, 2013
The microalgae Chaetoceros gracilis was cultivated to feed the rotifer Brachionus plicatilis. Microalgae and rotifers were grown separately, each for 10 days in a growing system volume of 62,5mL to 20L (1st phase).

Chaetoceros gracilis AS A BIOINDICATOR OF SEDIMENT QUALITY

open access: yesJurnal Ilmu dan Teknologi Kelautan Tropis, 2014
Chronic sediment toxicity tests could be used to evaluate the effects of sediment on critical stages in the life of an organism like invertebrate larvae and microalgae. Microalgae play an important role in aquatic ecosystem due to their role as producer in food chain producing organic matter and oxygen through photosynthesis process.
