Antioxidant Activities and Selenogene Transcription in the European Sea Bass (Dicentrarchus labrax) Liver Depend, in a Non-linear Manner, on the Se/Hg Molar Ratio of the Feeds
Espino, Marinelle; Eguiraun, Harkaitz; Diaz de Cerio, Oihane; Carrero, José Antonio; Etxebarria, Nestor; Martinez, Iciar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-31)Feeding 3.9 and 6.7 mg Hg/kg (Se/Hg molar ratios of 0.8 and 0.4, respectively) for 14 days negatively afected Dicentrarchus labrax growth and total DNTB- and thioredoxin-reductase (TrxR) activities and the transcription of four redox genes (txn1, gpx1, txnrd3, and txnrd2) in the liver, but a diet with 0.5 mg Hg/kg (Se/Hg molar ratio 6.6) slightly increased both reductase activities and the ... -

Reducing the number of individuals to monitor shoaling fish systems – Application of the Shannon entropy to construct a biological warning system model
Eguiraun, Harkaitz; Casquero, Oskar; Sørensen, Asgeir Johan; Martinez, Iciar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-08)The present study aims at identifying the lowest number of fish (European seabass) that could be used for monitoring and/or experimental purposes in small-scale fish facilities by quantifying the effect that the number of individuals has on the Shannon entropy (SE) of the trajectory followed by the shoal’s centroid. Two different experiments were performed: (i) one starting with 50 fish and decreasing ...
