Artemia: a potential source of glucocorticoids for fish larvae?

StressChron Framework:

Project code 053
Acronym ARTEMIA
Role Coordinator
Research area Unravelling the impact of chronic stress across vertebrates
Research topic Feed as stressor focusing on invertebrates (e.g. Artemia), mycotoxins and fish feed constituents
Vertebrate Fish
Species Invertebrate Artemia franciscana (Great Salt Lake, USA)

Abstract:

The research goal is to unravel whether Artemia, an invertebrate commercially used as exclusive feed in the larval stage of many Teleost fish in aquaculture, is a potential source of glucocorticoids, the stress hormones produced by vertebrates including fish, and can be a potential effector of the ontogeny of the hypothalamic-pituitary-interrenal (HPI) axis in fish larvae. Hereto, an ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) method for quantification of a glucocorticoid profile, as seen in Teleost fish, in Artemia was developed in an EN ISO/IEC 17025 regulated environment and analytically validated according the requirements of the Commission Decision No. 2002/657/EC. Hereby, focus was on Artemia franciscana (Great Salt Lake, USA).
