Analytical Strategy for Identification and Quantification of 13 Steroids in Sole (Solea senegalensis) Tissues, Eggs, and Larvae for Application in Aquaculture Studies of Reproduction
American Chemical Society (2021)Knowing the levels of steroids in fish is crucial for understanding the reproductive processes during fish development and for reproductive success in aquaculture facilities. Although some of these compounds are present ... -
Comprehensive strategy for pesticide residue analysis through the production cycle of gilthead sea bream and Atlantic salmon
Elsevier (2017-07)Plant ingredients and processed animal proteins are alternative feedstuffs for fish feeds in aquaculture. However, their use can introduce contaminants like pesticides that are not previously associated with marine Atlantic ... -
Determination of Putrescine and Tyramine in Fish by Micellar Liquid Chromatography with UV Detection Using Direct Injection
Bentham Science Publishers (2011)This paper shows how fish samples could be directly injected into a chromatograph, without any previous extraction, using micellar liquid chromatography, taking as an example the determination of two biogenic amines: ... -
Do background levels of the pesticide pirimiphosmethyl in plant-based aquafeeds affect food safety of farmed Atlantic salmon?
Taylor & Francis Group (2020-10-20)The substitution of fish oil and fishmeal with plant-based ingredients in commercial aquafeeds for Atlantic salmon, may introduce novel contaminants that have not previously been associated with farmed fish. The organophosphate ... -
Documentació d’un peix del Miocè inferior d’Esporles (Mallorca, illes Balears, Mediterrània occidental)
Ateneu de Natura (2022)Els fòssils de peixos són molt abundants a certs jaciments de les illes Balears. Generalment, però, aquests compareixen en forma de dents aïllades o otòlits; els fòssils d’espècimens complets són molt escassos. En aquesta ... -
Identification of new, very long-chain polyunsaturated fatty acids in fish by gas chromatography coupled to quadrupole/time-of-flight mass spectrometry with atmospheric pressure chemical ionization
Springer (2021-2)The characterization of very long-chain (>C24) polyunsaturated fatty acids (VLC-PUFAs), which are essential in the vision, neural function, and reproduction of vertebrates, is challenging because of the lack of reference ... -
Multi-class determination of undesirables in aquaculture samples by gas chromatography/tandem mass spectrometry with atmospheric pressure chemical ionization: A novel approach for polycyclic aromatic hydrocarbons
Elsevier (2017)In this work, a method for the analysis of 24 PAHs in 19 different matrices, including fish tissues, feeds and feed ingredients, has been developed using gas chromatography coupled to triple quadrupole tandem mass ... -
Novel analytical approach for brominated flame retardants based on the use of gas chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry with emphasis in highly brominated congeners
American Chemical Society (2015)The analysis of brominated flame retardants (BFRs) commonly relies on the use of gas chromatography coupled to mass spectrometry (GC-MS) operating in electron ionization (El) and electron capture negative ionization (ECNI) ... -
Screening of Pesticides and Polycyclic Aromatic Hydrocarbons in Feeds and Fish Tissues by Gas Chromatography Coupled to High-Resolution Mass Spectrometry Using Atmospheric Pressure Chemical Ionization
American Chemical Society (2014-02)This paper reports a wide-scope screening for detection and identification of pesticides and polycyclic aromatic hydrocarbons (PAHs) in feeds and fish tissues. QuEChERS sample treatment was applied, using freezing as an ... -
